A REPOR UPON THE GRASSES AND FORAGE PLANTS .VXD FORAGE CONDITIONS OF THE EASTERN ROCKY MOUNTAIN REGION. BY THOMAS A. WILLIAMS, ASSISTANT A(;m)STOLOc;iST. PREPARED UNDER THE DIRECTION OF THE AGROSTOLOGIST. WASHINGTON: GOVERNMENT PRINTING OFFICE. 1898. y LETTER OF TRANSMITTAL. U. S. Department of Agbiculture, Division of Agrostology, Washington, I). C, April 23, 1898. Sir: I have the honor to transmit herewith, and recommend for publication as Bnlletin Xo.l2of this Division, a report upon the grasses and forage plants and forage conditions of the eastern Rocky Moun- tain region, by Thomas A. Williams, assistant agrostologist. Field agents of the division have been carrying on investigations in the region embraced in this report during the past three years, and Mr. Williams, of tbe division staff, has visited, during the seasons of 1S96 and 1897, the more important grazing districts, where, under the direction of the Agrostologist, he has studied the present forage problems of the region and investigated the native grasses and forage i)lants, noting their characteristics, distribution, general prevalence, and economic impor- tance; he has endeavored to ascertain how the most desirable sorts may be preserved or increased, and has also made close personal obser- vations with the view of determining some practical means of restoring the ranges to their original grazing value, or at least preserving them from further injury through careless and short-sighted practices. The present report is based upon these studies and investigations, as well as upon the results of work done by the field agents of the division. While carrying on these investigations the work of the field agents has not been confined to the districts easily accessible from the rail- roads and other common lines of travel, but, by means of wagon trips and side excursions on horseback, they have penetrated into the less-known localities, in every case making extensive collections of specimens and seeds, as well as obtaining all the data possible relating to the question of forage supply. One field agent thus covered nearly 1,(100 miles in a wagon trip of two months during the past season. (See fig. 1.) There has also been included much valuable information acquired through correspondence with i)rominent citizens and leading stockmen, who have most cordially resi)onded to letters of inquiry relative to the matters in question and materially aided the Department in the prose- cution of these grass and forage-plant investigations. Hearty thanks are here expressed to all those correspondents who have thus cooper- ated in the work of the division. 3 4 Some idea of the importance of the subject of this Eeport upon the Grasses and Forage Tlauts and Forage Conditions of the Eastern Kocky Mountain Kegion is indicated by the following statements: It is estimated from Report Ko. 7, Division of Statistics, that in the State of Wyoming about 15,000,000 acres are taken up by mountains and forest areas, about 10,000,000 acres are irrigable and hence suitable for general agriculture, while nearly 40,000,000 acres, or almost two-thirds of the entire State, may be regarded as pasture lauds only. In Mon- tana the proportion of pasture lands is fully as great as in Wyoming, while in Colorado it will probably fall but little below. At the beginning of the year 18U7 there were in these three States about 350,000 head of horses and mules, valued at about 89,000,000, over 3,000,000 head of cattle, valued at nearly $56,000,000, and over 6,200,000 head of sheep, valued at over $10,500,000, or a total valuation for the stock supported chiefly by these native pasture and meadow lands of about $75,500,000. The first report on the investigations of the forage plants of the Northwest, from this division, was Bulletin No. 5, on the Grasses and Forage Plants of the Eocky Mountain Region, by P. A. Rydberg and C. L. Shear. This was followed by Bulletin No. 6, on the Grasses and Forage Plants of the Dakotas, by T. A. Williams, aided by Prof. M. A. Brannon, of North Dakota, aud E. N. Wilcox and 1 )avid Griftiths, of South Dakota. Embracing much the same field is Prof L. H. Pam- mel's Notes on the Grasses and Forage Plants of Iowa, Nebraska, and Colorado, published as Bulletin No. 9 of this Division ; and another, on The Red Desert of Wyoming and its Forage Resources, by Prof. Aven Nelson, is now in press. In the present bulletin the topographical features of the region are considered, including a discussion of the soil, water supply, etc. This is followed by detailed accounts of the cultivated grasses and forage plants and the more important forage plants, both grasses aud species of other families, native to the region, concluding with suggestions on methods of improvement of the forage conditions of the ranges.

INTRODUCTION. Stock raising will always be an importaut iiidastry in the vast expanse of territory lying between the Kocky Mountains and the one- hundredth meridian. The early settlers recognized its many natural advantages for this purpose, and at once began to cover the hills and valleys with cattle and other stock. Under the stimulating influence of high prices, resulting largely from the demand created by the civil war, stock raising rajiidly grew to be an industry of immense proportions. At til St forage was plentiful ; everywhere the supply seemed inexhaust- ible, and the ranchnmn's chief concern was to get more stock in order that he might turn into cash the grasses of the prairies. Stock grew and fattened on no other feed than the native grasses throughout the entire year. At length, however, stockmen became aware of the fact that not only was there a possibility, but a probability, that the supjdy of forage would soon be exhausted if they continued to follow the old methods of stock raising. Under this old system of mismanagement the ranges were stocked to their utmost capacity, even for the most favorable conditions, and consequently the past series of dry seasons resulted in a great shortage of feed. Eanchmen are already confronted with the necessity of ])roviding extra forage supplies for use in seasons when the grasses on the range are short. With a view to finding some practical means of bettering existing conditions and encouraging stockmen in their efforts to grow forage crops, a series of investigations of the various forage problems existing in the West and Xorthwest, particularly in the States of Montana, Wyoming, and Colorado, is being carried on by the direction of the Secretary of Agriculture through the Division of Agrostology. These investigations are designed to secure full and accurate information regarding the present condition of the forage problem; what the great- est needs are, and how they can be met in the most practical manner; to study the native grasses and forage plants, their characteristics, dis- tribution, abundance, and value; to ascertain the best means of pre- serving the more desirable sorts, and to introduce into cultivation such as promise to be of value; to devise some practical treatment for the 8 ranges whicL will not only restore tlieir original grazing valne but guard against future injury through overstocking and other careless and shortsighted practices. The information upon which this report is based has been gathered from various sources. During the past three seasons iield agents of the division have been working in the different parts of the region in question studying matters pertaining to the forage supply. The writer has made two trips into the more important grazing districts, and, under the direction of the chief of the division, has studied the condi- tions and needs by consulting with the stockmen and collecting all facts likely to aid in the work of getting at a i^ractical solution of the Fig. 1.— In the field. various forage problems confronting the ])eople at the present time, and thereby laying the foundations for more intelligent and economical practices in the future. In April, 1897, the following circular letter with the aj^pended (jues- tions was sent to prominent stockmen, farmers, and others interested in the forage problem : Unitkd States Dei-aktment oi' Agricultcre, Division of Agrostology, IVashhigfon, T). C, Ajfril, 1S07. Deaii Sir: Under tlio direction of the Secretary of Agriculture this division is investigating the forage question in tlie Northwest, particularly in the States of ^lontana, Colorado, and Wyoming. In this investigation particular attention is being given to the native grasses and for.ige ])laats, their characteristics, distribu- 9 tion, abundance, and valne; the best means of preservinf;; the more valuable kinds, and the methods to be employed in reclaiming those ranges which have been ren- dered of little or no value for grazing, through overstocking or other causes. In order to obtain a more definite idea as to what the present conditions and greatest needs are, and to gain all possible information that will aid us in determining the most practical methods of improving these conditions, by the introduction and cul- tivation of new grasses aud forage plants or by the preservation and cultivation of native species, correspondence is hereby invited with all interested in the develop- ment and preservation of the stock-raising and dairying industries. There are over 225 different grasses native to this region, and it would be difficult to give an adequate estimate of their immense value as a natural resource. Ever since the Northwest has been settled these grasses have been the chief source of food for the many thousands of horses, cattle, and sheep raised there, and many of them will undoubtedly prove more valuable under cultivation than they are in the native state. Any assistance you may render in this undertaking, either by sending us the names and addresses of leading farmers, stock raisers, and dairymen of your region, or by furnishing information relative to the points above indicated, will be highly appreciated Yours, truly, F. Lamson-Scribnkr, Agrostologist. Approved : James Wilson, Secretary of Agriculture. (1) What is the chief forage problem in your section — that is, do you need hay plants, soiling crops, drought-resistant crops, winter forage, or early spring or late autumn forage? (2) How many head of cattle, horses, or sheep can be safely pastured to the square mile under existing conditions? (3) Has the stock-carrying capacity of the ranges and pastures in your section been diminished through overstocking or other causes? If so, to what extent? (4) What treatment do you recommend for restoring, renewing, and improving the rauges where they have been overstocked? (5) What are the most highly valued native grasses and forage plants, and are there any tame grasses or forage plants which might be profitably introduced on the ranges to take the place of the valuable wild grasses of former years? (6) What is the general character of the land in your locality, and what grasses flourish best on it? Answers were received from about 600 persons, and the following may be taken as representative of the ideas expressed by the great majority of them. From Governor Robert B. Smith, of Montana, tbe following answers were received: (1) We need drought-resistant crops and winter forage. (2) Fifty head of horses or cattle or 2,^0 sheep. (3) Where sheep range, destroyed at least one-half. (4) If sheep were compelled to be kept in certain portions of the range and the remainder left free for cattle or horses, the range would be fully restored in three years. Sheep destroy the range ; cattle and horses do not. (5) Blue-joint and buffalo-grass are the best native grasses. Do not know of any tame grasses to take their places. (6) Light gravelly land; soil not deep but rich, and with large per cent of alkali. Buffalo-grass and blue-joint flourish best. 10 From Hon. John C. Bell, M. C, of Colorado: (1) In the rncompaligre, Gunnison, and C4ran(l valleys, the San Luis Valley, and the upper portion of the Arkansas Valley, our great field plant is alfalfa. The mountain sides, mesas, and foothills are covered with bunch grass which supplies all herds from about April 1 to December 1. If we could find some grass that would flourish in the low foothills without irrigation for winter feed it would bo a great boon to all of Colorado. Our summer forage is ample and of the very best (luality. (2) The ranges vary so that no approximate estimate can be made. On some hiuh mesas where the snow is deep in winter the grass is very abundant, but lower down it decreases. But these ranges are ample for all the stock that can be wintered in the valleys below. (3) Not in the mountainous regions. (i) Cattle and horses rarely impoverish a range, as they do not feed in close bunches, but sheep tramp out and practically destroy the grasses wherever they are kept. Horses and cattle will not remain or feed with them on the range. (5) Buncb-grass and blue-stem in the mountain regions can not be surpassed unless some grass could bo found that would stand the drought in the foothills. (6) We have three varieties — adobe, black loam soil on the river bottoms, and the high " red oxide " mesa lands. Vegetables grow best on the black loam, wheat and oats on the adobe, fruit trees and alfalfa on the high mesa, though it is all better than the average lands of the country for any of the ordinary crops, and would probaljly produce most of the common grasses, though but little experiment has been made in this direction. From Hon. Jos. M. Carey, Cheyenne, Wyo.: (1) The introduction of a forage plant that will mature during our short seasons and will afford good grazing all the year, the seed of which would germinate and grow by simply being raked or '-disked in"on the native soil. The native grasses are so valuable that it would ho unwise to destroy them, but with nutritious grasses to supplement them the capacity of a given section for grazing purposes might be greatly increased. (2) This depends upon circumstances. Some sections as they were left by nature would scarcely carry an animal ; others, 30 to 40 head. Should say average 1.5 head for three hundred and sixty-five days. (3) Yes; but as soon as cattle are removed the ranges again grow up to the native grasses. When I speak of cattle I mean neat cattle and horses. Where sheep graze for a number of years weeds take the place of native grasses. (4) Kest. (5) Bunchi-grass, blue-stem, and buflalo-grass are the varieties best known to stockmen. I do not know of any. (6) Sod free from brush of any kind. The native grasses referred to; with irriga- tion all of the small grains and forage plants that are common in this latitucU' pro- duce well. Alfalfa does well everywhere in this State when irrigated, where the altitude is not over 5,000 feet. Three crops may be harvested; season's production, from 3 to 6 tons an acre. A glance tliroustriict from the report of Mr. David firiffitlis, who served as field a<;<'nt for the divinion in South Dakota and Wyoming under a commission extending fri>m the middle of July to the middle of September, 18137. 21 beds which hold water until late iu the summer. The trees getting started around these water-holes are supplied with sufficient moisture during- the growing season. The stockmen and Indians have exercised much vigilance of late in keeping out fires. Near Bixby it was stated that it has been ten years since fire has passed over that region. When fire does get started, it is not so destructive to trees and shrubbery as it would be if there was more grass on the ground. Almost invari- ably we found the feed very short near the water- lioles. During the summer the range cattle feed near the water, working back on to the o])en range as feed conditions de- ma n d . Consequently, by the time vegetation is dry enough to burn, the grass in the vicinity of the water- holes is very short and fire does not do so much damage. The timber along the Mo- reau is made up of cotton- wood, willows, buffalo berry, box elder, green ash, white elm, plums, and cherries, with buck-bush, poison oak, and various species of rose as uudershrubs. On the bluffs on either side are found Rhm trilohata and an occasional red cedar. Sage-brush ( A rte- misia JongifoUa) is common over limited areas in the western portion of the region, while species of cactus are common everywhere. The feed on the Indian reservation is much superior to that farther west, the main reason for this being that it is not pastured so closely. The Indians have only a few cattle, and it appeared that they were taking considerable pains to keep the feed along the Moreau River for winter use. However this may be, Ave saw but few cattle on the river bottom while on the reservation. Neither were any Indians seen except- ing at three points on the river. Their log houses and stables were in evidence all along, but no Indians or cattle to speak of. They were Fig. 4. — Fresli-water cord-grass (Spartina cynosuroides) : a, spikelet, showing three stamens; &, spikelet, show- ing the projecting stigmas of the pistil; c, the same, with the outer glumes removed. 22 congregated at Wliite Horse camp and tlie agency. Near each one of tliese bouses was a small piece of ground, from 2 to 3 acres, fenced and under cultivation. Their crops consist of corn, potatoes, pumpkins, and melons. These were usually well tended and a good crop. There were a few pieces of wheat which were an average crop. The Indians evidently do not cultivate the same piece of ground for many years in succession. It was not an uncommon thing to find patches of ground, which had once been under cultivation, all grown up to weeds, and the fence removed from it, possibly to get fresh soil, but probably more often to get rid of the weeds. It was learned that the Indians make almost no preparation for winter feeding, except to save, as much as pos- sible, the feed around their winter quarters. As they have but a small bunch of cattle, they are able to keep close watch of them. (^)uite a number of cattle were seen which were being driven down to the agency to be sold for beef They were invariably in good condition. After leaving the Missouri bottoms no big sand-grass {Calamovilfa longifoUa) was noticed until the party arrived at the Moreau near White Horse camp. Big cord-grass {Spartina cynosuroides) (fig. 4) is the principal grass along the ravines and gullies, and big sand-grass is very common on the knolls farther west. The distribution of big sand- grass, of course, throws much light on the character of the soil. Both of these grasses were pastured closely in the western portion of the region where the feed was short. Usually these grasses are not cut for hay, but this season it is said that they will form the bulk of it, owing to the scarcity of wheat-grass, Prairie June-grass {Koekria cristata) is a much more important grass on the high prairie in the eastern portion of this region than anywhere else we visited. The small table lands back 3 or 4 miles from the river invariably contain fine growths of this grass, at times almost to the exclusion of the other grasses. There was a large area near Virgin Buttes that stood 10 inches high and so thick that the heads which were then ripe gave a brown appearance to the whole area. It is very common on all the high ground. rorcui)ine-grass {Stipa spariea) and needle-grass {Stipa comata) are found to some extent all along the Moreau bottoms, the latter becoming a very important pasture grass to the westward. Feather bunch-grass {S. viriclula) is more important on the highland regions eastward. Here it is a very valuable pasture grass and is often found with western wheat-grass {A(/ropi/ron spicatum) and blue grama [BouicUma oUfi<>- stachya) in sufficient (piantity to nnike considerable hay. The more important grasses and forage plants of the region are as follows: Blue grama {Boiiteloua olujostaclnja), western wheat-grass {Agropyron Hpicatum)^ big blue stem {Andropogon provhicialis), prairie June-grass (Koeleria cristata), big cord-grass (.S>rrr^/?ja cynosnroides), needle-grass {Stqjci comata), feather bunch-grass {S. riridula), big sand- grass {Calamovilfa longifoiia), buffalo-grass [Bulbil is dactyloides), 23 Dakota vetch {Lotus amtricanus), wild rye {Elymns canadensis), and Carex fiUfoJia. The hist is of special value early iu the season. Dakota vetch {Lotas amcricanus) is very abundant along the river bottoms. There are often large patches of it which are almost pure. If this proves valuable under cultivation it will be easily propagated, for it produces an abundance of seed. It has, however, the disadvan- tage of ripening its seed unevenly. Usually the older pods have burst open before the later ones have ripened. BUTTE POST-OFFICE TO DEVILS TOWER. The change that takes place as one proceeds along the Owl Butte road from Dead Horse Creek toward the foothills of the Black Hills is something wonderful. One passes from a region where the ranches are 5 to 40 miles apart, where there is practically no cultivation, and where there is nothing to break the monotony of the scene but bunches of cattle feeding in the "draws" and an occasional patch of scrubby box elder and ash on the creek bottoms, to a thickly settled region, where thei c are good buildings, excellent crops of grain and hay, and where everything iu the shape of vegetation makes a thrifty growth. The greater part of the land along the Belle Fourche from Butte to the Tower is fenced, either for growing cultivated crops or for winter feed. For about half the distance from Butte to Belle Fourche the route was through a narrow lane left for a road and in which there was no feed whatever — everything being pastured closely. The farmers fence their crops, pastures, and hay land, and turn their cattle out into the roads which lead into the Black Hills on one side and into the open range on the other. The party, at times, experienced some trouble in finding feed for their horses. Nearly everything depends on irrigation here, the water being car- ried from tributaries of the Belle Fourche by a system of ditches and sluices onto the land. Nowhere is water taken from the Belle Fourche itself, the reason being that the river has not sufficient fall to enable farmers to get the water onto the land without too great an expense. It was learned also that the volume of water in the river fluctuates greatly, a rise of many feet occurring in a few hours at times when heavy rains fall in portions of its drainage basin. Damming has been tried in several localities without success. As the tributaries from the hills are quite numerous, the farmers are usually able, by judicious management, to get a sufficient volume of water for their crops from them. Usually the water is exhausted before the middle of July, but by an intelligent use of their supply during May and June they are able to raise fine crops. In many instances the farmers get along by building a dam across a gully and holding the water derived from melting snows and spring rains until it is needed later iu the season. In the immediate vicinity of Belle Fourche opportunity was afforded to study the effect of an abundant supply of water the entire season. It is here obtained from one of the tributaries of the Bed Water. 24 Here was found a most luxuriant growth of both native and culti- vated vegetation. As flue fields of wheat were found here as in the great small-grain belt in the eastern part of the State, while the hay croj) was something wonderfal. The uuirrigated lands, however, pre- sented an appearance not unlike the drier portions of the open range farther east. The principal hay crop is alfalfa, of which, they obtain about 4 tons per acre from three cuttings, which is the usual method of handling. The farmers were experimenting with a fourth cutting this year, and were considerably encouraged over the prospect at the time the region was visited. This crop is prized very highly because of the fact that they are able to get such a yield per acre. Many other hay crops are grown very successfully, but none yields such a quantity of feed as this one. Kedtop makes the finest growth here of any place visited on the trip. On the Seth Bullock ranch there is a large meadow which w;is sown to redtop and timothy eight or ten years ago. The timothy is now nearly all run out, while the redtop this year is a fine stand about two feet high. Besides the above may be mentioned timothy, white sweet clover {Melilotus alha), millet, and June clover, all of Avhich make good growths. White sweet clover {Melilotus alba) is so persistent in its habits that it assumes much of the characteristics of a weed along the ditches and among otlier jierennial forage crops. It makes an immense growth wherever it gets started on irrigated land. At Belle Fourche was seen near a spring about an acre that stood about 9 feet high. Native grasses are also irrigated with good success. When, however, a piece of ground is irrigated year after year, that invaluable species, Aiiropyron spicatum, runs the other grasses out. Several instances of this were seen and attention was called to it, not only in the vicinity of Belle Fourche, but farther west, in Wyoming, as well. The most striking example was near Snoma, S. Dak., where there was a meadow of 30 or 40 acres of this grass, with a crop of about 2 tons to the acre. About one-fourth of it was headed out. It was raining at the time of the visit and the grass, therefore, looked fresh and thrifty. Such a large field of this glaucous leafed grass made a very pretty sight. It was ascertained that this meadow had l>een irrigated and cut lor five consecutive years with a good crop of hay upon it each year. Such a condition is really extraordinary, for ranchmen on the range and even the farmers in the eastern part of the State are seldom able to cut crops of this on the same ground for more than two years in succession. Even when pastured closely year after year the quantity of feed becomes very small. P>ut this is sim[)ly one more evidence of Avhat a ])roper amount of water will accom])lish when applied to this soil. llarnyard-grass (Panicum cnis-galli) makes a fine growth along the ditches and roadsides where the sod has been ])artially subdued. It 25 has two distinct forms of growth. Along the ditches and among other grasses it assumes an upright form, while along roads and in barnyards, where the ground is packed down to some extent, it is almost prostrate and often strikes root at the joints. It appears to thrive as well under this form of irrigation as it does under artesian irrigation in the eastern part of the State. Squirrel-tail grass {Hordeum Juhatum) is a bad weed wherever the perennial grasses are ii^rigated on low, alkaline ground. Besides the usual forage crops there is a great deal of rye, wheat, and oats cut for hay. Winter rye is usually sown. These crops are resorted to only in the drier portions of the region or where no water is available for irrigating purposes. Although small grain is raised here successfully with irrigation, the main crop is hay. There is consider- able feeding done during the winter. The big cattle companies make provision with the settlers here, and also with the ranchmen farther out on the range, for the wintering of calves and weak cows which are picked up during the last beef " round-up " in the fall. The distribution of precipitation is very peculiar. The rainfall is much more abundant in the vicinity of the Black Hills than on the open range on either side. While irrigation is resorted to with profit wherever practicable, the region is not dependent on it entirely. Occa- sionally good crops of grain are raised without irrigation, but it is rather uncertain. When wheat and oats are sown for the grain and the crop proves to be a failure, it can usually be told in time so that it can be cut early enough to make good hay, which is always in demand. In the vicinity of Sundance, Wyo., and elsewhere along the base of the Bear Lodge Mountains, very fair crops are usually raised with no arti- ficial watering. This year the prospects near Sundance were very good, but they had the misfortune of being "hailed" out. The Bear Lodge Mountains are in general covered with pine {Pint(s sco2)uIo}'um), with an occasional grove of oak, poplar, and birch. The pine is especially heavy on the outer slopes of the mountains and in the "draws" and gulches farther up. Along the divides and edges of "draws" there is very fine pasturage. The range cattle do not get in here to any extent, partly from choice but principally on account of the fact that ranchers have fenced most of the land along the base of the mountains separating the open range from the mountain pasture lands. Common along the Bear Lodge Mountains is King's fescue (Festuca kingii), which makes a fine growth below the lower timber line and is very common at higher elevations. It is highly prized by the ranchmen along the base of the mountains on account of its early spring growth. It furnishes pasturage at a much earlier date than any other native grass. Occasionally it makes some hay, but it is looked upon as a pasture rather than a hay grass. 26 DEVILS TOWER TO NEW CASTLE. As one proceeds up the Belle Foiircbe from the Tower he can not helj) but notice the gradual decrease of the pine timber. It becomes more and more scrubby until it practically disappears at the mouth of Wind Creek. On the bluffs ou either side of the stream is a growth of jtine, with some oak, and on the bottoms there is a good growth of Cot- tonwood, with more or less of the bufi'alo berry, green ash, box elder, and an occasional plum and cherry thicket. There is always a very vigor- ous growth of roses, buck-bush, and sage-brush. There are large areas on the bottoms covered with long-leafed sage {Artemisia longifoUa), almost to the exclusion of other vegetation. Some difficulty was experienced iu finding feed for the horses in the upper Belle Fourche region, not that the country is not productive, but there are too many cattle. It would be difficult to tell what grasses grow ou the river bottom were it not for the winter pastures which are fenced in. During the two nights spent here the party managed to camp in these winter pastures where there were good growths of blue grama {Bouteloua olifjostachya), needle-grass {Sfipa comata), feather bunch-grass {S. riridula), western wheat-grass {Agropijron spinitum), jirairie June-grass {Koeleria cristata), big sand-grass [Calamovilfa longifnlid), big cord-grass {Spartina eynosHroide.s), slender cord- grass (ularly called "gumbo," and washes very badly. The rain does not soak into the ground much, but runs off" into the streams, often swell- ing them to enormous extent. Amcmg the sage-brush and cacti are good growths of grasses, generally those which do not form a sod under ordinary conditions. Among the most important may be mentioned 27 needle-grass {StijJO, comata) and western wheat-grass {Agropyron fipi- cation ). On the divides are found big sand-grass {Calamovilfa loiuji- folia) and blue grama {Bouteloiia oligostachya), while big cord grass {Spartina cynosuroides) and salt-grass {Distichlis spicata) are the most common on the low ground, is eedle- grass {Stipa comata) is a very important grass m this region. Xorthwest" of New Castle, near the junction of the Burlington and Missouri River llailroad and Skull Creek, it is especially common. In this vicinity and extending south- ward into the oil regions are large areas among the sage-brush where no other grasses grow. As one approaches Inyan Kara Mountain the country assumes much the appearance of that around Sundance, as would be expected. There are more streams, and consequently more water available for irrigation. The rainfall is also more abundant, and the soil has more sand and humus in its make-up. The mountain and all the elevations in the neighborhood are covered with pine, while groves of poplar, birch, and oak are common. The creeks have a growth of cottonwood, box elder, and green ash. Springs of pure soft water are common near the base of the mountain. Near Inyan Kara we found a ranchman drilling with the expectation of getting a tiow of water. He started in last year, when he struck a stratum from which water raised within a few feet of the surface. Be renewed his efibrts this year, hoping to get a sufficient flow to irrigate from. The open range is closely pastured here also. Here again it was learned that until about four years ago haj" could be cut anywhere on the upland, but for the past few years the cattle have become so numerous that they keep the grass eaten off so closely that the effect is much the same as successive cutting year after year. Occa- sionally a ranchman attributes the short crop of the past few years to drought, but the majority of them agree that it is due to overstocking. We found more and better farming along Skull Creek than along the Upper Belle Fourche. This is probably due largely to the better facili- ties for irrigation. There are ranches at short distances along the creek, and considerable hay was being put up. Alfalfa is their main crop whenever they can get water onto the land. Timothy is raised to some extent, and rye and oats are common hay crops. Xo running water was found until the party got down near the Burlington and Missouri River Railroad. There is as good an illustration of the effect of water on the growth of vegetation here as one could wish to see. On the one hand there is a perfect wilderness of sage-brush {Artemisia longifolia and A. tridentata) as far as the eye can reach, with the usual light growth of grass, forming no sod to speak of; on the other, native grasses, alfalfa, oats, and garden truck make a fine growth with arti- ficial watering. 28 THE SOUTHERN BLACK HILLS REGION. The arable laud in the region between Xew Castle, Wyo., and Eapid City, S. Dak., is contined to the valleys and creek bottoms which lie between the difterent ridges in the Black Hills uplieaval. The crops raised are about the same as at Belle Fourche and along the eastern foothills. It appears to be the practice in localities here as at Belle Fourche to seed for a crop of grain, and if the yield does not promise well it is cut for hay before it becomes thoroughly ripened. Some very fine crops of alfalfa, wheat, and oats were seen in Spring Creek Valley. Eedtop and timothy are common on the larger areas of low ground. Eedto]) is espe- cially abundant, and there was a fine crop of hay in Rapid Creek Yalley to the southwest of Rapid City. The climatic conditions are in marked contrast with those at a lower elevation. Harvesting was in jirogress in the vicinity of Belle Fourche the 1st of August, but I'O or 25 days later, when the party crossed the Black Hills on their return trip, a great deal of wheat and oats were still green. Only about one- half of the crop through the hills had been cut at this late date. A beautiful arrangement of native grasses is found along the foothills near Rapid City. There are a great many cattle pastured here, and the grasses are conse(piently kept eaten down ([uite closely. There are three species, which form a perfect sod in places. The country is roll- ing— sometimes hilly. In the depressions are patches of ground several acres in extent which are as smooth as though they had been laid out by artificial means. On these areas are full sods of blue grama {Bouteloua oli(fostachya), black grama {B. hirsiita), and builalo-grass [Bnlbilis (lactyloides) (see fig. 5), arranged in natural lawns, as it were, according to nature's own fantastic designs. It made a very pretty siiiht. Xo artificial lawn could be more desinible.

RAPID CITY TO PIERRE. Nowhere on the trip was better feed found than along the trail from Rapid City to Pierre. No pasturing had been done here except at certain points, as Pceno Tlills and Grindstone Buttes. This is due mainly to the fact that our route lay along the divide, where water is scarce. It was the intention of the party to take the Bad River road, and they would have done so had they not been informed that everything was pastured closely all the way. Blue grama {Bouteloua olujostacliya) makes a fine growth here and was nice and green the 1st of September. Con- siderable hay was being put up in the eastern portion of the region. It consisted principally of Western wheat-grass {Agropyron splcatum) and blue grama [Boutelona oligostachya), together with some feather bunch- grass {Stipa viridula) and needle-grass {8. comata). In the "draws" there is more of the Agrojjyron and less of the Boutelona. In the larger draws there is a good growth of big cord-grass {Spartina cynositroides) and on the knolls a light growth of big sand-grass {Calamovilfa longi- folia). At Pierre the cattlemen were much exercised over the fact that the grass on the range was so backward in ripening. They were fearful lest it should remain green until frost struck it, thereby leaving their winter feed in poor condition. They were therefore well pleased with the hot, dry weather which prevailed during the first ten days in Sep- tember. CULTIVATED GRASSES AND FORAGE PLANTS. The failure of the ranges to sux^ply sufficient forage for all seasons of the year has led to an Increased effort on the part of the stockmen and farmers to cultivate the various standard grass and forage crops. In many instances experiments have been made with the different novel- ties introduced and sold by seedsmen or distributed g; atuitously by the United States Department of Agriculture. As was to be expected, the old and so-called ''tame'' grasses have refused to accommodate them- selves to the extreme conditions of soil and climate prevailing in some parts of the region, and while a few of the newly introduced plants have proved valuable, many others have shown themselves to be practically worthless. The '' tame " grasses most commonly found in meadows and pastures are timothy, redtop, Kentucky blue grass, smooth or Hun- garian brome-grass, meadow fescue, and orchard grass. The millets and the various small grains are quite generally grown for summer for- age and for hay, and corn and the sorghums, both saccharine and non- saccharine varieties, are occasionally grown for fodder. Nearly all the 30 common clovers are successfully grown in some part of the region, alfalfa and red clover being in most general cultivation. Very few of the large ranches are without fields of timothy, redtop, clover, or alfalfa; often all are grown on the same ranch. Sometimes these fields cover hundreds of acres and yield thousands of tons of hay. Almost without .exception they are irrigated, at least for a portion of the season. In many localities the proprietors of the large ranches prefer not to bother with the extensive cultivation of forage crops that would be necessary to properly feed their herds during the winter, depending upon the small ranchmen and farmers in the valleys for their winter forage sup- ply. The liay is sold to the ranchmen, or more often the cattle are brought to tlie farmer and he winters them at so much per head. This winter feeding of range stock is becoming quite an industrj' and could, no doubt, be more generally practiced with advantage to both the large and the small ranch owner. Up to the present time winter feeding is largely, in fact almost entiiely, confined to cows, calves, and bulls: the most of the stock being expected to -'rustle*' its living on the range except during very stormy weather, when a little hay may be fed. TIMOTHY. Phleum jJratense. This is more widely cultivated than any other " tame " grass in the eastern Rocky Mountain region. The cheapness of the seed, the ease with which a meadow can be seeded down, and the excellent (juality of the hay make this grass a great favorite. In most localities irrigation is necessary to grow it successfully, but with plenty of water enormous yields are often obtained, particularly in the rich valleys in the north- ern part of the region. Reports of the successful cultivation of this grass have been received from every county in both Montana and Wyoming, and from nearly every county in Colorado, but always under irrigation except in some of the moister valleys in or near the moun- tains. Sage-brush lands when cleared, irrigated, and seeded to tim- othy make fine meadows, but the greasewood lands are too strongly im])regnated witli alkali. Timothy can be grown successfully at a higher altitude than most of the other commonly grown grasses, and is becoming quite generally established in waste places and along trails throughout the entire region. Several of the field agents of the divi- sion have reported finding it well established in many places in the mountains. Professor Pammcl found it llonrishing at an elevation of 10,.jOO ieet in northern Colorado, and the writer found it at a similar elevation in the central part of the State. In the Bear Lodge ]Moun- tains and in the Black Hills it is very abundant at 5,000 and (1,000 feet, making a very fine growth, and is sj)reading very ra])idly in moist, open situations along the trails. In the Big Horn Mountains of Wyoming and in the Spanish Basin in Montana it was found to be abundant, growing with alpine timothy {Phleum alpinum L. ) ar liom 31 7,000 to 8,000 feet or more. This ability of timothy to establish itself and thrive at comparatively high altitudes makes it of special value for a large i)ortioii of this region. Speaking' in this connection Mr. W. S. Coburu, of Delta County, Colo., says "timothy grows to perfec- tion up to an elevation of 9,000 feet," and Mr. T. P. McDonald, of Carbon County, Mont., says "alfalfa aud clover do well below the 4,500-foot level, but above that altitude timothy is the most successful." RBDTOP. Af/rostis alha. This grass stands very close to timothy in its importance as a meadow grass for this region. Its cultivation is less general than that of timothy, however, being more strictly confined to the lower mountain valleys and better irrigated localities, and it is much more generally grown in Montana than in either Wyoming or Colorado. Like timothy, it is becoming well established in the native meadows and waste places. It thrives best on quite moist bottom lands, and is especially valuable on meadow lands liable to overflow. It is a common practice to sow this grass in irrigated native meadows to supplement the native spe- cies. It occupies the low marshy places and resists. the encroachments of sedges and rushes better than timothy or the common native grasses. Though usually grown in connection with other grasses or with clovers, it makes a fine meadow when grown alone under proper irrigation. One of the finest redtop meadows ever seen by the writer was on a large horse ranch on the Gray Bull Eiver, Wyoming. About 80 acres of the grass were standing at the time of the visit (August, 1897), and some had already been harvested. The land was the common sage-brush land of the valley, and had been given but little cultivation before being seeded down, but was well irrigated. The field was " as even as a floor," and as the mower passed along, it was noticed that the grass came well up along the sides of the horses. Almost all the cultivated land on this ranch was devoted to this crop, which is fed to fine-bred horses. KENTUCKY BLUE GRASS. Foa pratensis. The principal use of Kentucky blue grass in this region is for lawns. With irrigation fine lawns can be made almost anywhere, if the land is not too strongly impregnated with alkali. The great difficulty often experienced in getting a good stand of this grass is one of the chief drawbacks to its culture here. The seed as sold in the markets is too often so poor that the farmer fails to get a good stand for his first sow- ing and gives up in disgust. Then, again, it takes some time for the grass to form a good sod, and the average Western farmer is too impa- tient for immediate results to wait for it. ifevertheless this grass is becoming quite abundant in many of the older settled localities and is gradually working its way into the meadows and pastures. Together 32 with Canadian blue grass {Poa compressa)^ low spear-grass {Poa anmia), and redtop, it follows along the irrigating ditches, forming bright green borders, and affording many juicy mouthfuls for the cattle and other stock. Like most of the other cultivated grasses, it thrives best in the rich valleys of the lower mountains and foothills, where it is ])rotectcd from drought and the excessive heat of midsummer. It is indigenous in many parts of the Rocky Mountain region. SMOOTH OR HUNGARIAN BROME-GRASS. Brornus inermis. Of all recent introductions smooth brome (see fig. 6) is the most promising hay and pasture grass for the dry portions of the Northwest. i^^ot only does it possess ex- cellent drought - resistant qualities, but it starts much earlier in the season than the common grasses and continues growing well into the autumn, two things very nnich to be desired in a grass for cultivation in this region at the present time. In Colorado the grass lias been tried in a number of localities with good success. In speaking of grasses for dry situations oil theraiiges, Mr. R. E. Beatty, of Arapa- hoe County, says, ^^ Brornus inermis comes the nearest to a suitable grass that we have tried so far;" Mr. Thomas R. Pace, of Gar- nett, "recommends smooth brome-grass," and Mr. George C. Baker, of ]\Iosca, sayj ^'Brornus iiwrmis is our best tame grass." It is regarded as the most promising of the introduced grasses tried at the Colo- rado experiment station. The grass seems to have been given less attention in Wyoming than in either Colorado or Mon- tana. Mr. Griftiths, in his report for the past season, speaks of seeing a plot of it on the ranch of JNIr. John Baugh, of Carlisle, Wyo. Ue says, Fi(i. 6.— Smooth or Hungarian lirome-grass (Bromxis iner- mil): a, Hi)ikclet; 6, tlowering filume seen from the back; c, floret seeu from tlio anterior side, allowing palea. 33 <'Mr. Baugli has been experimentiug' two years, botli with and without irrigation. He seems to think that the smooth brome-grass does not thrive so well under irrigation. The effect of irrigation was really quite peculiar. The irrigated portion of the plot was fresh and green (middle of August) while the unirrigated portion, though it had made a much better growth, was completely dried up. I am not certain but that a thorough wetting at less frequent intervals would have produced better results. He irrigates by means of a tank and windmill. The water is conducted to the gar- den by a pipe and the crop is sprayed. All his garden truck looked well. Cabbage and to- matoes were especially fine." In Colorado smooth brome has done well under irrigation, particularly when pastured. In Montana smooth brome has received considerable at- tention, and reports regarding it are very satisfactory indeed. Hon. Paris Gibson, of Great Falls, says, ''In the experi- ments I have made with new forage plants I find Bronius inermis the most hardy. It api)ears in the spring much earlier than our native grasses." Similar reports were received from Messrs. M. W. Jones and E. Vine, of Miles City, and from Director Emery of the State Experi- ment Station. Judging from these reports and from the excellent results already ob- tained in growing this grass in Canada, as well as in the Dakotas and other Northwest- ern States, it seems probable that smooth brome will prove of great value for cultivation on the dry lands of the iS^orthwest. It should be given a thorough trial, especially as a grass for reseeding worn meadows and pastures. THE FESCUES. About the only fescue that seems to have been tried to any extent is meadow fescue {Festuca elatior ^yraten.sis), and this is only occasionally seen in cultivation— usually in mixture with other grasses or with 20013— :No. 12 3 Fig. 7. — Sheep fescue {Fe.itnca ovinii). 34 clovers. Ou rich loamy soils, with abundant irrigation, it seems to do quite well. Favorable reports have been received from several points in central Colorado and central and southern Montana. Mr. Griffiths found it doing well in northeastern Wyoming. It is frequently met with along irrigating ditches and in public parks in the cities and towns, often occurring in waste places as an escape and already well established in favorable situations. It does not seem to thrive in soils containing much alkali. At the Utah Station this grass has been grown with fine success as an element in permanent pastures and meadows, and it is altogether likely that it can be so used in many portions of the Eocky Mountain region. Many native forms of both sheep fescue {Festuca ovina) (fig. 7) and red fescue {Festuca rubra) occur in this region, and although the cultivated varieties have been given little, if any, attention, it is not unlikely that they could be used to advantage in reseeding the ranges, particularly in the foothills and lower moun- tains. ORCHARD GRASS. DactylU glomerata. Like meadow fescue, tliis grass has received but little attention from farmers and ranchmen in this region. It has been tried at the experiment stations, sometimes with success and sometimes without. It requires fairly rich soil and a reasonable amount of moisture, and hence thrives best on irrigated lands of the valleys and benches. It has succeeded quite well at the Utah station, and good reports of it have been received from central and southern Montana and from nmny parts of Colorado. It was seen on several ranches near Evanston, Wyo.. the past season and was making a fine growth. Mr. \V. C. Burke, of Las Animas, Colo., in an answer to the questicm as to what grasses and forage plants do best in his locality, includes this grass, with the statement that "when irrigated it produces about 2 tons of hay per acre." It is deserving of more general cultivation as an element in mixtures for permanent meadows and pastures and for seeding down sparsely wooded areas. ALFALFA. By far the most important forage plant cultivated in this region at the present time is alfalfa. Scarcely a farm or ranch under irrigation can be found in the entire region without its alfalfa field, and on many of the larger ranches hundreds of acres are devoted almost exclusively to this crop. It flourishes on the l)ettcr drained valley lands and irrigated bench lands in all parts of the region where the altitude is not too great, and alfalfa liay constitutes the principal winter feed for many thousand head of horses, sheep, and cattle. Of recent years it is being extensively used in fattening sheep and cattle for market. There is great need of a good su])plem('ntary forage to be fed along with the alfalfa. It is so rich in muscle-making food elements that, as ordinarily 35 fed, its full value is not obtained, and ranclinien are beginning- to realize the necessity of mixing it with corn fodder, sorghum, prairie liay, or other forage containing an excess of fat forming elements in order to feed in the most economical manner. Three or more cuttings are obtained each season unless, as is often the case, it is more desirable to pasture off" the later growth. This is done when summer i)asturage is scarce or when there is no market for the hay and the ranchman gets enough for his own use from the first one or two cuttings. During the past season it was learned from sev- eral ranchmen in the Big Horn Basin tliat they very seldom made more than two cuttings, for the reason that they needed no more for wintering their own stock and the price of the hay was so low that it paid them better to pasture tlieir fields for a portion of the season. This was in a region where the summer pasturage was short because of drought and previous overstocking, though at the present time the number of stock kept on the range is undoubtedly much below what the land ought to support under a proper system of grazing and supplementary feeding. One of the things which makes alfolfa so valuable for this regiou is its ability to thrive on land containing a considerable quantity of alkali. There are few cultivated crops that will stand as much alkali as this. The injurious effects of too much water upon the growth of alfalfa is well illustrated by the conditions at present prevailing in a number of localities in Colorado, particularly in the southern i)art of the State. The soil, either from natural causes or as a result of the methods of irrigation practiced, has become saturated with water to witliin a short distance of the surface. As a consequence the roots of the alfalfa rot and the plants become sickly and finally die, rendering it impossible to produce anything like a permanent meadow. Here in Colorado, as well as in many other parts of this region, the best success is obtained with alfalfa on the bencli lands. It is surprising what a small amount of labor is required to obtain a good alfalfa meadow in some portions of this region. For example, it is a common practice to give sage-brush land no more plowing or other preparation than is necessary in taking oft" the sago-brush. The brush is cut and grubbed out, raked up and burned, and the seed sown directly on the unplowed land, covered and watered. The soil is so loose as to require little or no stirring, and water is the oidy thing necessary to make it produce abundant crops of alfalfa. Of course more thorough preparation will give an evener and more lasting meadow, but the writer has seen many fine alfalfa meadows on land untouched by the plow except to make ditches for distributing the water. RED CLOVER. Next to alfalfa, red clover is the most widely cultivated legiuninous forage crop in this region. It seems to be more generally grown in 36 Montana than in either Colorado or Wyoming, and its cultivation is chiefly confined to rich valleys and bench lands near the mountains where there is a good supply of moisture or where irrigation is prac- ticed. It is usually grown with timothy and other meadow grasses, and is cut for hay or used as a soiling crop. Very fine crops are raised in central and southwestern Montana and in northern and central Colo- rado, and it is occasionally seen elsewhere in these States. Bed clover is not generally grown in Wyoming, though it is being tried in many localities with very fair success. During the past season it was observed in successful cultivation in Crook, Johnson, Bighorn, and Uinta counties. ALSIKE. Although less commonly grown than red clover, alsike is certainly a valuable crop for many jjarts of tliis region. Many farmers who have grown them side by side prefer the alsike to the red clover as a forage crop for their respective localities. For example, Mr. C. C. Willis, of Horse Plains, Mont., writes that he much i)refers alsike on account of its heavier yield of forage and greater drought-enduring qualities. Excellent fields of alsike and timothy were seen in 1890 in the Gallatin Valley, and reports of the successful growing of this clover have been received from various points in central and southwestern Montana, northern Wyoming, and northern and central Colorado. As a general thing the alsike seems to be hardier than red clover and is better adapted for permanent meadows, and some maintain that it does better on the heavy '' gumbo " soil found in so many i^laces in the Northwest. It has also given good results in many parts of the Dakotas, where it has received a thorough trial. It deserves more attention from farmers and ranchmen in the Northwest generally. WHITE CLOVER. It is rarely that this clover is sown in this region excei)t on lawns or in dooryards, but its ability to gain a foothold and maintain itself among other vegetation is well shown in the fact that it is found everywhere in patches of various sizes along the margins of irrigating ditches, in waste places, and in pastures and meadows. Beports from several counties in central and western Montana and central Colorado indicate that it is occasionally sown in i)astures and is growing in favor, more particularly for use in i)astures i'or sheep and dairy stock. In extended trips through this region in both 1890 and 1897 the writer found but very few instances of its having been sown ])urp()sely in pas- tures, though it was often present even in native pastures in greater or less quantities. The excellent sliowing made by this clover during the season of 1897 was very notic«'able throughout the West and Northwest generally, particularly in the older-settled districts. In eastern South Dakota, northwestern Iowa, and eastern Nebraska this clover made a remark- 37 able development. Almost everywhere aloug roadsides, in waste places, and in pastures could be seen the masses of white blossoms. Pastures in which scarcely an appreciable amount of the clover had ever been observed before were white with it. In many cases no clover seed has ever been sown in the pastures, but it has gradually worked in from accidental sources, and though the progress has undoubtedly been slow, it has nevertheless been sure, and this clover has come to occupy a very important place among the vegetation of the pastui es. The tendency of white clover to develop in alternating periods of light and heavy growth has often been observed in the past, and its appearance in such quantity in the present instance is a good illustration of the changes in the composition of pastures that are going on constantly, though they are not always for the betterment of the pasture, as in this case. MISCELLANEOUS FORAGE CROPS. Aside from the preceding list of standard grasses and forage plants, there are a number of crops of greater or less importance that are grown in the various parts of the region. In most cases their cultiva- tion is not general, sometimes because the plants are not well enough known and sometimes because of their inability to thrive under the conditions prevailing over a large part of the region. In the dry portions of Colorado where irrigation is not practiced the sorghums, both saccharine and nonsaccharine varieties, are grown to some extent for winter forage and for soiling. The great drought- enduring qualities of the sorghums and their ability to thrive on land containing considerable alkali render them especially valuable for cer- tain portions of this region. Mr. E. E. T. Hazen, of Phillips County, Colo., reports good success in growing several of the nonsaccharine varieties (yellow milo maize, brown doura, and Jerusalem corn), and S. Keedham, of Prowers County, regards " sorghum as very valuable for winter forage on nonirrigable lauds." Only the early maturing- varieties like Early Amber are grown in Wyoming and Montana, and these not to any great extent. The common cereal crops, such as rye, oats, wheat, and barley, are often grown for forage. Eye and oats are used for this purpose more often than any others, although it is a common practice to cut any cereal for hay if conditions are such that it is not likely to mature a crop of grain. Eye is being very successfully grown for late and early pasturage in many localities, and its cultivation is becoming more general each year. It is already quite extensively grown in central Colorado, northern Wyoming, and some parts of Montana. Sown in early autumn, it gets the benefit of the rains and snows of fall, winter, and early spring, and usually matures a fair croj) of grain in addition to furnishing much pas- turage, when spring-sown crops would fail unless artificially watered. Other crops that have been grown in some parts of the region with success are field peas, rape, sand or hairy vetch, and esparcette. Par- 38 ticularly encouraging results are reported from central Colorado regrarcl- ing the growing of field peas for forage, and the crop has done well in many other parts of the region. Profitable crops of rape, vetch, and esparcette are reported from Montana and elsewhere. Millet is more gericrally grown for hay than any other annual. Com- mon millet and Hungarian are usually preferred for the average uplands. Broom corn millet is sometimes grown as a grain crop, but yields too lightly for a hay crop where the better varieties can be grown. As a general rule all the millets are used as '' catch crops " rather than as regular crops, and as such they fill an important place in north- western agriculture. They are most commonly grown in the northern part of the region. NATIVE GRASSES AND FORAGE PLANTS. There are about 1*70 species and varieties of grasses known to be indigenous to this region. Naturally a great majority of these are too small or too rare to be of much importance in the production of hay or pasturage. The most valuable species are quite widely distributed, althougli occasionally a species of but local occurrence may be of con- siderable importance in its particular locality, as is the case with some of those occurring in the mountains. The great economic importance of the native grasses is at once appar- ent when one recalls the many thousands of sheep, cattle, horses, and mules that are raised in this region, and that depend entirely upon the native grasses and forage plants for subsistence for from eight to twelve months of the year. That the quality of the forage aftbrded is excellent is shown by the fact that most of the vast numbers of fat cattle and sheep annually shipped to the Eastern markets from this region receive no other food than that furnished by the natural mead- ows and pastures of the ranges. From the economic point of view the important native grasses of this region may be classed into two groups, namely, meadow grasses and pasture grasses. To be sure, no hard and fast line can be drawn, but as a general thing the best pasture grasses are of little use for hay, and within late years, at least, wherever good hay-producing grasses occur in any great extent, they are fenced off from the open range and pre- served for winter forage. NATIVE MEADOW OE HAY GRASSES. LOWLAND MEADOWS. The grasses most abundant in the meadows at thelower altitudes are usually quite different from those which i)red()raiiiate in the mountain meadows, although it is seldom that any sharp line occurs where the strictly mountain grasses begin and the lower valley grasses leave off. The change is rather a gradual one. Hay meadows are almost entirely 39 confined to the valleys of the larger streams, the prairies and hilly conutry being given over to grazing. Occasionally a rich plateau or <' bench'' may be found with a sufficient sujiply of moisture to produce a growth of grass luxuriant enough for hay, but these are rare. The grasses of most importance in the meadows in the lower valleys are wheat-grasses {Agropyron spp.), meadow-grasses {Poa spj).), manna- grasses {I'anieularia spp.), sand-grasses or blue-joints {Calamagrostis spp.), and wild rye- grasses {Elymus spp.). Of these the wheat- grasses are by far the most valuable. A great many species occur in this region, but there are three which are of special importance as hay-producing grasses. These are Western wheat-grass {A[/ropyron spi- catum), known also as Col- orado blue-stem, slender wheat- grass {Agropyron tene- rum) (see fig. 8), and false quack-grass {Agropyron pseudorejien.s). These grasses are very generally distrib- uted over the region, and grow naturally on a great variety of soils. All respond readily to cultivation. Usu- ally all that is necessary to convert a piece of good sage- brush or valley land into a wheat grass meadow is to clear off the brush and large stones, keep off the stock, and water the land. The grasses will soon take complete possession. On nearly every well- kept ranch in the eastern Rocky Mountain region can be seen fine natural meadows made in this manner. Western wheat-grass is usu- ally more abundant than either of the other sorts, and it is not an uncommon thing to see a meadow of 40, 80, or more acres composed almost exclusively of this grass. Without irrigation it is rarely possi- ble to cut more than one crop in two years, as the grass requires time to recuperate. Even with irrigation it is seldom possible to obtain good crops for many consecutive years without cutting up the sod to over- come its "hidebound" condition and give opportunity for the growth Fig. 8.— Slender wheat-grass (Aijropyron tenerum). 40 of new slioots. Under favorable conditions, however, these meadows may yield good crops for a number of years with nothing more than proper watering. Mr. Griftiths reports seeing a meadow of about 40 acres the past season, near Snoma, S. Dak., yielding a crop of about 2 tons of hay per acre, which had afforded a good croi) for five consecu- tive seasons. In the wet or boggy places in lowland meadows the wheat-grasses are replaced principally by the meadow-grasses and, if the soil is sandy, the sand-grasses or blue joints are often present in considera- ble quantity. Of these grasses reed meadow- or manna-grass [Panieularia americana) (see fig. 9) and nerved manna- grass (P. nervata) are common in very wet boggy places unless the soil is too strongly impregnated with alkali, when they are often replaced by alkali meadow-grass [PuccinelUa airoides). This last grass is usually quite rigid and wiry and grows in close bunches, but furnishes considerable for- age in some localities. Often it is about the only grass to be seen among the sedges and rushes of the wet, alkali mead- ows, and in such places it is more succulent and i)ahitable than when growing in drier sit- uations. It is very abundant in the overirrigated meadows along the Little Laramie Kiver in Wyoming, and is quite widely distributed over the Western plains and through- out the valleys in altitudes be- low 8,000 feet. The true meadow-grasses {Poa si)p.) are of much more value gener- ally than those just mentioned. These are most abundant in the moist meadows near the foot of the mountains. Among the valuable kinds are the indigenous forms of Kentucky blue grass (Poa pratcn.sis), the "bunch-grasses" {Poa buvUeyawt, P. laerujata, and 7'. Incida), Wyom- ing blue grass (P. wheeleri), bench-laud spear-grass (/'. (irida), wood- land meadow-grass (P. nemoralis), 'Nevadd blue grass (/*. nevadensis). and foMl meadow-grass or false redtop [P.Jlava). Many of these are of as much importance, under present conditions, for pasturage as for Fig. 9. — Keed meadow-grass (Vanicidaria atnericaiia) . 41 hay, but with a proper supply of water all afford good yields of excel- lent Lay. In the valleys Kentucky blue grass, in either its native or introduced form, is perhaps most commonly seen, and is becoming more and more abundant as the country is settled up and the native meadows brought under irrigation. Of the "bunch-grass" Poas, P. hucMeyana (fig. 10) is apparently the most widely distributed, being, if anything, more common on the dry uplands than in the valleys, and hence x)erhaps more properly to be regarded as a pasture grass. However, under irrigation it be- comes less densely tufted, the leaves are broader and more luxuriant, and the yield of hay is good. Smooth bunch-grass (P. Uevigata) and pale bunch-grass (P. lucida) are more often found in the lowlands and are excellent meadow grasses. They are most abundant in the middle Rocky Mountain region. Wyoming blue grass is often found with Kentucky blue grass in moist meadows and along banks of streams, but it ascends higher uj) the mountains, where it is frequently abundant in open pine and spruce woods, some- times occurring in dry situations, but generally where the soil is well supplied with moisture. It is especially abundant in parts of Wyoming and central Mon- tana, usually occurring at an al- titude of from 0,000 to 8,000 or 9,000 feet, but sometimes ascend- ing to 10,000 feet. In the rich moist soil of "burnouts" in pine and spruce woods it makes a magnificent growth. Bench-land spear-grass (see fig. 11) is quite generally distributed throughout this region. It usually occurs in rather dry meadows, often in patches of considerable extent, but never forming a close sod, as does Kentucky blue grass. The forage is of i)oorer quality than that furnished by the latter and the yield is lighter. However, the grass is one of the earliest of the native species and thrives better on dry soil than Kentucky blue grass. Under cultivation it would probably be more valuable for pastures than for meadows. a -J, Fig. 10. — Buncli-grasis {Poa huckleyana) 42 There are few of the native meadow-grasses that grow naturally under such a wide range of soil and climatic conditions as woodland meadow-grass in its several varieties. It is common in Avoodlands along the prairie streams, and follows up the valleys into the foothills and mountains, where it becomes an important element in the moist meadows. It also occurs on rocky hills and mountain sides, some of its forms flourishing at an altitude of 10,000 feet, or even more, in Col- orado. Some of the forms growing in the rich lowland meadows approach fowl meadow-grass in size and appearance, and afford a large amount of excellent hay. Nevada blue grass (fig. 12) is more common on the west side of the Conti- nental Divide than on the east, but it is nevertheless sufficiently abundant in the latter region to form an impor- tant part of the vegetation in many of the natural meadows. It occurs as far east as the Pine Ridge of Nebraska and the Black Hills of South Dakota, but is most abundant in the valleys among the foothills and mountains. Some forms of it grow on rather dry soil in open woodlands and on rocky mountain sides. It prefers rich soil with a medium supply of moisture and does well under irrigation. Under favorable conditions it makes an ex- cellent growth of leaves, and yields a large amount of hay compared with most of the native species of Foa. It is rarely found above an altitude of 8,000 or 9,000 feet in this region. Fowl meadow-grass is not as abun- dant in the immediate vicinity of the mountains as it is farther to the eastward, but nevertheless is found quite plentifully in certain localities. It occurs most frequently along streams about the edges of thickets, and on moist banks and bottom lands subject to overflow in the early i)art of the season. For such places it is a valuable grass, making a good yield under conditions that would "drown out" most of the common grasses. It is much more valuable for hay than for pasturage. In some localities this grass is called false redtop. The sand-grasses or blue joints found in the meadows are remarkable for their abundance of long root-leaves and the consequent large yield \ Fig. 11.— Beiicli-land spcargrass {I'oa arida). 43 of hay, which is usually of an excellent quality. One of the most widely distributed species is the common blue joint {Calamagrostis canadensis), locally known as false or native redtop. This grass is often very abundant in moist, sandy river bottoms, and some of its many forms ascend well uj) into the mountains. It has been cultivated with good success and is worthy of extended trial in the Northwest. Sand-grass or yellow-top [Calamagrostis americana) is also well dis- tributed throughout this region. It is most commonly found along the sandy banks of streams, ponds, and lakes, often (espe- cially along sloughs) forming a well-defined "yellow-top" zone of vegetation, noticeable from a considerable distance because of the characteristic color of the grass. It seems to thrive better in alkali soils than its relatives, and is generally confined to com- paratively low altitudes. Big sand-grass {Calamovilfa loufjifolia), altliough common on the plains and in the valleys throughout, is not so valuable as the preceding species because of the very coarse and fibrous nature of the forage which it produces. It is most commonly found in dry, sandy swales and on sandy hillsides, and in the bad lands and other dry dis- tricts, where the better grasses are scarce, it is often plentiful. In such localities it is regarded as a valuable grass, and is used for hay. There are several of the wild rye-grasses that occur in suffi- cient quantities to be of importance in the vegetation of the native mead- ows. All are most abundant as a rule in rich, open, rather dry meadows and on hillsides, and are rather coarse, harsh plants, affording ctmsider- able hay of an average quality. The kinds of most importance are common wild-rye {Elymus canadensis), Macoun's rye-grass [U. macounii), and giant rye-grass (jE. condensatus). The first of these is the most gen- erally distributed, and is probably the most valuable, although the second, which is also quite common, is a finer grass and produces a better a alpina) and mountain meadow-grass {Foa leptocoma) are the pre- dominating species. An interesting thiug in connection with the dis- tribution of these two grasses was observed in northern Wyoming the I)ast season. In the Bear Lodge range, in northeastern Wyoming, alpine blue grass was frequently met, and it was also very abundant in the mountains at the head of Meeteetse Creek in the north- western part of the State, but extended search failed to re- veal any of this grass in the Big Horn Mountains in the north central part of the State and nearly midway between the other two localities. Mountain meadow-grass was ' very abundant in the Big Horn Mountains, and was also found in the mountains at the head of Meeteetse Creek, but was not seen in the northeastern part of the State. Alpine blue grass is most abundant in sandy or gravelly soil near the streams, and moun- tain meadow-grass j) r e f e r s cold, wet, boggy meadows and mountain sides. Alpine timothy is very wide- ly distributed at the higher elevations in the Eocky Moun- tain region. It is qui^e abun- dant in the Black Hills above 6,000 feet. In the Big Horn Mountains it vies with tus- sock-grass for first j)lace in many of the meadows at 7,000 to 8,000 feet, particularly on the western side of the range, where it is much more abundant than on the eastern slope. In central Montana it is most plentiful at and above 6,500 feet, rarely occur- ring below 6,000 feet, the ordinary limit for common timothy. It is rarely found below 9,000 feet in Colorado, except, perhaps, in the northern part of the State, but is plentiful up to 13,000 feet. Hay made from this grass is highly prized by ranchmen, especially for horses. Fig. 13. — Wyoming blue grass (Poa wheeleri). 46 Mountain foxtail (fig. 14), which is also sometimes called mouutain timothy, has much the appearance of true mountain or alpine timothy, but is usually more robust and of a softer texture and produces a better looking hay, much like that from the cultivated meadow foxtail {Alojyecnrus 2)rattnsis), which this grass resembles in habit of growth. Although found throughout the Rocky Mountain region, and having similar altitudiual limits, it is much less common as a rule than alpine timothy. It is abundant in the rich, moist meadows of the Spanish Basin and elsewhere in south- western Montana, and makes a remarkably luxuriant growth, frequently reaching a height of three or four feet, and is one of the most promising of the native grasses for cultiyation in meadows at the higher altitudes. ' Several of the native brome- grasses are of great value in the native meadows at an altitude of from 5,000 to 8,000 feet in Wyoming and Montana and from 0,000 to 9,500 in Colorado. The most valuable of these brome- grasses are short-awned brome [Bromus breviaristatus) (see fig. 15) and Western brome {Bromus pumpellianns). Both are coarse- growing perennials and occur throughout the Kocky Mountain region, chiefly in the rather dry valleys and "i^arks;'^ the former selecting the moister situations and the latter the drier ones. Although they are often found growing together, Western brome- grass seems to have a somewliat higher alti- tudiual limit, its point of best development usually ranging from 500 to 1,000 feet above that of short-awned brome. The latter is occasionally abundant down as low as 4,000 feet in central Montana, while the former is but rarely found at that altitude. In northern Wyoming short-awned brume is most abundant at from 5,000 to 7,000 feet and Western brome at from 0,000 to 8,000. Both of these grasses have been cultivated in some parts of the Northwest with suc- cess and promise to be valuable for meadows at high altitudes. West- ern brome has very much the same appearance and habit of growth as Fio. 14.— Mountaiu Foxtail (Alopecurus occidentalis) . 47 the recently introduced smooth or Hungarian brome which is being grown with such excellent success in the semiarid West and Northwest. Tussock-grass [Deschampsia avsintosa) is perhaps the most abundant and widely distributed grass in the native meadows of the Eocky Mountain region. It has a very wide altitudinal range. For example, it is abundant in wet meadows in the Gallatin Valley about Bozeman, Mont., at an altitude of about 4,000 feet, and ascends to above the timber line in the mountains on either side of the valley. On account of its tufted habit of growth it does not form an even sod, and hence does not make a good meadow by itself In most instances, however, it is accompanied by other grasses, such as the true meadow-grasses, redtop and blue joint, which fill in the spaces between the tufts, making a fairly good meadow sod. Some observers have reported this grass as of no practical value for either hay or pasturage, but such state- ments are not borne out by the reports of our field agents nor by the opinions advanced by the ranchers. While neither the yield nor the quality of the forage is equal to that obtained from timothy or redtop, there can be no doubt that the grass fills an important place Fig. is.— Short-awned Brome-grasa (Bromus hreviaris- among the native meadow faf-^>:«,tbe floret seen from the side; 6, palea.c, ^ . joint of tbe racliilla; d, gram; e, lower portion of pis- and pasture grasses of this til, showing lodioules;/, young seed or grain. region. It flourishes in wet, boggy places where many of the better grasses can not grow, and by its dense tufts of tough fibrous roots helps to convert these bogs into usable meadow lands. Moreover, continued mowing and pasturing have the eflect of reducing these tufts materially, so that with a few other grasses to act as fillers a comparatively even sod is produced. Such a condition of things may be seen in many of the mountain valleys, as, for example, in the valley of the Little Laramie River near Sheep 48 Mountain. In the varieties of tussock-grass growing in the higher altitudes the leaves become considerably reduced, and, of course, pro- duce little forage of any sort, but the varieties growing in the meadows at from 4,000 to 6,500 feet develop a much greater leafage and aftbrd a large amount of hay and pasturage. A form of red fescue is not uncommon in the moist meadows at from 4,000 to 9,000 feet altitude in the northern part of the Kocky Mountain region, and is of much value for hay in some localities. It seldom forms tufts of any size, spreads by means of very slender underground stems, and is usually found mixed with other grasses. It is quite abun- dant in the Spanish Basin and else- where in southwestern Montana, and also in the Big Horn and Shoshone mountains in Wyoming. Eough-leafed bent occurs natur- ally in wet, boggy meadows and along banks of streams and ditches. The best hay-producing forms occur at elevations of from 4,000 to 0,000, or occasionally 7,000, feet. This grass produces an abundant leafage, much more than the common redtop, and also produces a large amount of seed — two things very desirable in a grass for cultivation. In the wild state it seems to be even more hardy than redtop, and while flour- ishing best with plenty of water it will, nevertheless, endure consider- able drought when once iirnily es- tablished. It is quite an important element in the native meadows in portions of northern Wyoming and central and southern Montana, and is perhai)s more common on the west side of the Continental Divide than on the east. As ordinarily seen in the natural condition, rough-leafed bent has a closely tufted habit of growth, but when thicl^ly seeded, as when in cultivation or occasionally in native meadows when conditions are favorable, this habit is largely lost, and a fairly even sod is formed. Its good quali- ties as a meadow grass commend it to those experimenting with our native species. It will doubtless be found to be better adapted for meadows at higher altitudes than most of the common so-called tame grasses. There are several of the oat-grasses found in greater or less abun- dance in the meadows and "parks" of the mountains and foothills of FiQ. 16.— Kocky Mountain oat-grass (Dantho- nia intermedia). 49 this region. The most important are Californian oat grass {Danthonia californica), Eocky Moimtaiu oat-grass [Danthonia intermedia) (see fig. 16), and Parry's oat-grass {Danthonia parryi). As a rule these oat grasses occur naturally in rather dry meadows and on mountain sides, Californian oat-grass being more inclined to seek moist situations than either of the others. It is the largest of the native oat-grasses, reaching a height of 3 feet under favorable condi- tions, and is also the most abundant Northwestern s])ecies. In northern Wyoming and Montana it forms a considerable portion of the meadow vegetation at from 5,500 to 8,000 feet. It is occasionally found as low as 5,000 feet, but is most abundant at from 6,000 to 7,000 feet. On rich, irrigated meadows it makes a very fine growth. It is rarely found as far south as Colorado, where it is replaced by Parry's oat- grass. Eocky Mountain oat grass is often found growing along with Califor- nian oat-grass; but it is a smaller plant, preferring rather drier soil and having a somewhat higher altitudinal range — seldom occurring below 7,000 feet, abundant at 8,000 to 10,000 feet, and ascending to 11,000 feet or even 12,500 feet in Colorado. It is probably of more value for pasturage than for hay. Parry's oat-grass is most abundant in the park region of Colorado, but also occurs in southern Wyoming. Although occurring naturally in rather dry meadows and on mountain sides, it makes a fine growth under irrigation and is occasionally found in some quantity in timothy meadows. It has a much more tufted habit of growth than Californian oat-grass and its altitudinal range — from 7,000 to 10,000 feet — corre- si)onds very well to that of its more northern relative. Although of local occurrence it is abundant in places, soujetimes almost completely occu- pying the open woods and parks in the mountains of central Colorado. The blue joints are usually conspicuous elements in the vegetation of the moister mountain meadows. They are the chief grasses in many of the deer parks in the higher mountains, and are ijarticularly abun- dant in the wet, boggy, open aspen thickets so frequently found in the Northwest, There are about a half-dozen species which are found in sufficient quantities to be of importance as forage producers. By far the most abundant is mountain blue-joint {Calamaf/rostis canadensis acuminata), a near relative of the common blue joint, which it replaces in the higher altitudes. It produces a large amount of excellent hay in the wet, sandy or gravelly valleys along the mountain streams, and usually occurs at an altitude of from 5,000 to 8,000 feet in the North, but ascends to 10,000 or rarely to 11,000 feet in Colorado. In northern Wyoming and central and southern Montana it makes an enormous development in the rich, moist soil of some of the mountain parks, frequently covering areas several acres in extent with a dense growth, reaching a height of 3^ or 4 feet. Northern blue joint or Langsdorff's reed-bent {Galamagrostis lanc/s- dorffii) is often found growing along with mountain blue joint and has a 20013— No. 12 1 50 similar range, but is much less abundant antt Las rather higher alti- tudinal limits. In localities where it is plentiful it is highly prized by stockmen, by whom it is often called " purpletop" on account of the l^revailing color of the inflorescence. It is much more common to the northward, being but rarely found as far south as Colorado, and then only in the higher mountains. Other blue joints deserving special mention are Scribuer's blue joint {CaJamagrostis serihneri) and Suksdorf's blue-joint [G. sulsdorfii). Both are northern in distribution, the latter being found in this region only in central and western Montana and most abundant west of the Continental Divide, and tbe former reaching down into central or rarely into southern Wyoming and Colorado. Both have an altitudinal range of about 3,000 feet, seldom occurring below 5,000 feet or above 8,000 feet in Wyoming and Montana. Suksdorf's blue joint, although reach- ing its best development in the moist land of the valleys, is often found on the drier ridges and mountain sides. NATIVE PASTURE GRASSES. Naturally much the greater portion of the grass land is used for grazing. At the present time nearly all the land not under irrigation is used for this purpose. This includes by far the larger part of the upland prairies, the bad lands, tbe broken foothill country, and the accessible mountainous country. Some of these pasture lands, notably those in the mountains and higher foothills, can be used during only a portion of the year, but the remainder are grazed through the entire year. In some localities cer- tain portions of the range are protected during the growing season in order that the grass may make a good growth and furnish forage for fall aiul winter grazing. Sometimes the stock is kept from these areas by fencing, but often the ranchmen, by common consent, keej) the stock on other ranges during the summer, and bring it to the protected areas only when forced to do so by the approach of severe winter weather. In localities where the meadow lands and winter pastures are fenced in, the open range is usually in very bad condition. Every ranchman is eager to get his " share" of the oi)en and free range, and naturally turns out all his stock during the summer. As a result, the grasses and better forage plants are eaten up or trampled into the ground before the end of the season. What wonder that the grasses are dying out on the o])en range! The wonder is that they have survived as long as they have. During the past season, while making wagon trips through the Belle Fourche and Big Horn Basin countiies, it was often necessary to drive many miles in order to find sul'licient ])asturage for the team. All tlie grass lands not under fence "were ] ticked bare in July and August, and it was imi)ossible to get feed along the trail except by obtaining permission of the ranchers to cami) inside the inclosures. Of course the grasses are l)eing pre- 51 served witbin the fenced areas, but these comi)ose but a relatively- small part of the total pasture lands, and the get all-you-can system is rapidly and certainly ruining the ojien range. In jjarts of the range region the scarcity of stock during the past few years, together with a few favorable growing seasons, has allowed the grasses to recuperate somewhat, but already the stockmen are beginning to increase their herds in order to be able to take advantage of the anticipated rise in prices of beef cattle, mutton, and wool, and there is danger that those lauds not already overstocked will soon be so unless something can be done to convince these stockmen of the shortsightedness of such a policy. In the higher foothills and mountains the pasturage is generally in good condition — much better than on the prairies. There are two prin- cipal leasoiis for this. In the first place, there is usually a good supply of moisture, and in the second place, the lands can be grazed during only a portion of the year on account of the heavy snowfall. xVs the lands can be grazed for but four or five months of the year at the out- side, there is a long j^eriod during the early part of the season when the grasses make a considerable growth, so that they are already well along in the vseason's development, sometimes maturing seed, before grazing begins. GRASSES OF THE PLAINS. Out on the open ranges of the plains, however, there are few locali- ties in which the pasturage is anything like as good as in former years. Leading stockmen from nearly all parts of the plains region estimate that the stock-carrying capacity of the pasture lands has been reduced on the average from 40 to 50 per cent in the last ten or fifteen years. The real reason for this is overstocking. The real stock-carrying capacity of a given area of pasture lands is the amount of stock that can safely be grazed on it during a dry or unfavorable season; and if these lands are to be kept in proper condition this limit should never be exceeded except perhaps temjDorarily during particularly favorable seasons; and the number of stock should be reduced as soon as it is seen that the grasses are being grazed too closely. Under the i)resent system, or rather lack of system, of controlling the open grazing lands, it is hardly to be expected that the ranchman will do otherwise than to continue to try to get his " share" of the forage on the open range, and in so doing will continue to add to its already overburdened condition. There are many thousands of acres of the imblic lands in this region that are of more value for grazing than for any other purpose, and in view of their importance and of the great danger of permanent injury resulting from the present methods of grazing it would seem urgent that some rational system of controlling them should be devised and adopted at once. All the native grasses are grazed by stock to a greater or less extent, but many kinds are too small to afford much forage; others are too 52 coarse and woody, or otherwise unpalatable, to be of much value; and still others, while affording nutritious forage, are of most value for hay, and have been considered in the preceding pages of this report under the discussion of the native meadow-grasses. The principal i^asture grasses of the dry plains region are the gramas {Bovtelono spp.), buffalo-grass {BulhiUs dacti/loides), wheat grasses, already discussed under meadow-grasses, prairie June-grass [Koeleria cristata), and needle-grasses {8ti2)a spp.). Other grasses of considerable value for graz- ing, but of more or less local distribution, are Indian millet {Eriocoma cnspklata), rush- grasses {Sporobolus spp.), Montana sand-grass (Ca/awta- grostis moutancnsis), salt- grass {Di-siicJiUs siylcata), and several of the bunch-grasses and wild ryes already men- tioned. There are three gramas found in this region, and all are valuable pasture grasses. The best, and by far the most abundant, is blue grama {B o ntelo u a oligosf<(clii/a). (See tig. 17.) It is one of the most generally distributed grasses of tlie prairies, and also occurs in considerable (quantities on the higher bench lands and mesas, in the foothills, and in dry soil here and there in the lower mountain valleys. Every- where it is regarded as an exceedingly valuable grass for both summer and winter pasturage, but i)arti('nlai'ly for the latter, vying with buffalo-grass for lirst place. At the ])resent time it is probably of greater actual vahie on account of its more general occurrence, greater yield of forage, and greater ability to hold possession of the soil under excessive pastnringand extremedrought. In therather loose, sandy soil, so common to the prairies of this regicm, blue grama forms closely sodded areasofvarying extent which, on accountofthe ])ur- plish color of the foliage, stand out in strong contrast to the prevailing Fig. 37. — Bine grama {Boutelona oligostachya) : a, empty glunu-s of a spikclct ; 0, spikelet with the empty glumes removed. 53 pale color of the remaining grass vegetation. Often these areas may be found alternating with similar areas of the much paler buffalo-grass, and the checkerboard appearance thus given to the prairie is peculiarly strik- ing. Although primarily a pasture grass, blue grama, under favorable conditions of soil and moisture, makes a fine growth of leafage suffi- cient to afford a good yield of hay of a very flue quality. Under ordi- nary conditions, however, this grass cures so well on the ground that stockmen prefer to use it for winter pasturage rather than go to the trouble of putting up the hay. Black grama [Bouteloua hirsuta) is much more local in distribution than blue grama, to which it is very similar in ax)pearance and habit of growth. It is con- fined largely to rather lim- ited areas on sandy or grav- elly knolls and hillsides, and is valuable chiefly because it thrives in these poor soils, furnishing considerable psis- turage where but few other grasses can do more than simply exist. The third grama found in this region that deserves special mention is tall or side-oats grama (Bouteloua curtipendula). (See flg. 18.) It is a larger grass than either of the foregoing, and, while occurring throughout, is more abundant in the rich prairie soil of the eastern portion of tlie region. It produces a fine growth of long, slender leaves and on good soil makes a good yield of hay. In Nebraska and the Dakotas, where this grass is very abundant, it is regarded as of more vahie for hay than for pasturage, as it yields well, and the tough, rather harsh leaves are more readily eaten by stock as hay than wlieu in the fresh state. In the principal range region, how- ever, the grass is seldom present in the meadows in much quantity, and on the drier soils the growth is not sufficient for hay; but it cures well on the ground and is readily eaten by range stock which are more accustomed to feeding on harsh herbage. Fig. 18.— Tall or side-oats grama {Bouteloua curtipendula): a, one of the short spikes; b, a spikelet; c, a splkelet with the outer empty glumes removed. 54 There is no other orass which has a reputation for excellence for both summer and winter pasturage equal to that of buffalo- grass. However, not all of the praise bestowed upon this grass really belongs to it, for the gramas are often confused with it, and to them, particularly to blue grama, belongs much of the credit given to buffalo-grass in many parts of the range region. In the minds of many ranchmen "buffalo-grass" includes blue grama and black grama as well as the true buffalo-grass {Bidbilis dactyloides), while in the minds of others grama or " gram- mer," as it is often pronounced, includes all three. However, there is no doubt of the great value of the true buffalo- grass for pasturage. That it is one of the most palatable of native grasses is shown by the fact that, with plenty of other grasses on every hand, stock will keep it eaten close to the ground, and this is probably the reason that it is one of the first grasses to be killed out in over- stocked ranges. It is reported to have practically disappeared from many places where it was formerly one of the commonest species, but while this is no doubt true of some localities, it is certainly not true of all. Examination has shown that it is still quite abundant in some of these localities, but is easily overlooked, as it is kept grazed so closely that it is seldom able to make enough development to show its charac- teristic habit of growth, much less to bloom and mature seed. The wheat-grasses usually furnish a larger percentage of the pastur- age on the prairies than is generally supposed. Tlie most valuable varieties for grazing are provided with underground stems or root- stocks, which run along a short distance below the surface and at fre- quent intervals send up erect branches, either bearing only tufts of leaves or more rarely producing "heads." When too closely grazed, or during unfavorable seasons, much of the growth of the plant is made by these underground stems and very few, if any, fertile branches are devel- oped. On this account many people have an idea that these grasses grow only once in every two or three years, when as a matter of fact the actual yield of forage may be almost as much for an "off" year as for any other. Although regarded primarily as meadow or hay grasses, the wheat-grasses furnish a large part of the pasturage throughout the entire range region, and on the more strongly alkaline soils are otten the only grasses of any value to be found at all. The needle-grasses {^tipa spp.) are among the most conspicuous members of the grass vegetation of the plains and lower mountains and foothills. All produce a relatively large amount of leafage, which makes an excellent quality of forage. During the late summer, when the seed is maturing, some of the needle-grasses cause much trouble and often severe in.jnry to stock, ])articularly to sheep, as the sharp-pointed needles or "spears" work into the llesh of the animals, making painful sores and sometimes causing the death of the animal, in some of the best forage-producing species the "spears" are very blunt, and hence do little or no damage. Where the range is kept closely grazed the 55 plants seldom seed in sufficient quantity to be troublesome. As soon as the seed ripens the " spears'" fall and work into the soil, so that these grasses can be used for hay or late grazing. The common needle-grass {Stipa comata) of this region is valuable for both hay and pasturage. On poor rocky or gravelly soils, where it is one of the characteristic species (see tig. 19), it affords a large amount of pasturage, and on the rich prairie soils it makes a good yield of hay which is considered by many ranchmen to be equal in quality to "blue- stem" or wheat-grass hay. Here in the range region it takes the place of porcupine-grass {Stipa spartea), so abundant in the Lower Missouri Valley region, but which only occurs in any considerable quantity along Fig. 19.— a bit of the "range" in N. E. Wyoming. (Photographed by David Griffiths.) the eastern limits of the range. In some parts of the range, as for examx)le in some localities of central and northern Wyoming, the com- mon needle-grass sometimes composes the entire grass vegetation of the sage-brush prairies. Another of the needle-grasses common in some of its many forms in this region is that most commonly known as feather bunch-grass {Siipa viridula). This is usually found in rather dry sandy soil, and forms dense tufted masses of leaves and stems, which afford good grazing. On account of its very blunt-pointed "spears" it seldom does any dam- age to stock and, as it endures close feeding well, it is one of the most desirable of the needle-grasses for grazing. Because of its densely tufted habit of growth and less luxuriant production of root leaves it is 56 of less value for liay than common needle-grass. Nelson's needle-grass {Stipa nelsoni) and purple-top needle-grass {Stipa minor) are also of value for pasturage, but both belong more properly, perhaps, to the higher altitudes. On the Big Horn ranges, at about 8,000 feet altitude, purple-top needle- grass is an important pasture grass and is also frequently cut for hay. Sleepy- grass {Stipa vaseyi) is quite abundant in the south- ern part of the eastern Rocky Mountain region. It takes its common name from the fact that in some localities it is thought to have a narcotic effect upon stock eating it. It is a coarse-growing grass, and the forage could hardly be very palatable in any event. How- ever, in times of scarcity of pasturage it is quite closely grazed, in central Colorado at least, but whether with any ill effects has not been detinitely ascertained. It is possible that the narcotic principle is not everywhere produced in '/j^ injurious quantities. One of the best early pas- ture grasses on the range is prairie June-grass {Koeleria cristata). (See fig. 20.) It is widely distributed, ti(mrishes on a variety of soils, and is one of the earliest grasses to afford pasturage on the prai- ries. It has a tufted habit of growth and seldom exceeds a foot in height on the dry prairies, but in moist, valleys it fre(iuently reaches 2 feet or more and affords an excel- lent (piality of hay. It nuitures its seed early and then dries up, fur- nishing l)ut little fresh pasturage afterwards unless well watered. It usually seeds heavily. Stockmen regard it as one of the most valuable native pasture, grasses because of its earliness and palatability. To many it is known as wild or prairie timothy, because of its external resemblance to the comnion cultivated timothy. One of the most common and valuable "bunch-grasses" on the plains is Poa buvklcyana. It is most abundant on the high elevated plains and ri Fig. 20.— Prairie June-grass {Koeleria cristala) : a. empty gluiin's; b, tlie two Horets raised above the empty glumes. 57 bench lands nearer the mountains, and is usually accompanied by- prairie June grass, blue grama, and some of the wheat-grasses. It is not as early as prairie June-grass, but affords a larger amount of forage and is much better for winter pasturage. It has a very wide distribution in the Rocky Mountain region and is represented by a great variety of forms, some of which, as already mentioned in another connection, are valu- able hay producers. In poor sandy soil, or in that containing a large percentage of alkali, the rush -grasses {Sporobolus spp.) are impor- tant pasture grasses. They are all rather harsh and un- palatable and are valuable chiefly because they thrive in soil that will produce none of the better grasses. When for- age is plentiful, stock will not eat them to any great extent, and the plants soon become tough and woody, but during seasons of scarcity these grasses are, like others, kept closely grazed throughout the season and are tenderer and more palatable. During the past season a number of extensive pastures were observed in the Big Horn Basin composed almost exclusively of fine-top rush-grass or salt-grass {Sporo- bolus airoides). (See fig. 21.) These pastures were in alkali bottoms and old lake beds, and were almost the only grass- covered areas of any consequence in that locality. They were grazed by horses principally, and were reported to be improving with con- tinual pasturing. This grass is most abundant in the southern portion of the region, though occurring throughout. Among other rush-grasses of general occurrence in this region are rough-leafed salt-grass {Sporobolus asj)erifolius), a characteristic "bad- land " grass; sand rush grass {S. cryptandrus), often abundant in sandy prairies and river bottoms; and prairie rush-grass {S. depauperatus). There are two forms of the last occurring in this region; one found chiefly in dry soil of prairies and hillsides, too small to be of much value Fig. 21.— Fine-top salt-grass (Sporobolut airoides). 58 for forag^e, and the other in moist, more or less alkaline bottom land, tall and slender and producing a greater amount of forage. Another grass abundant throughout this region in strongly alkaline soils, but of little value except in times of scarcity of forage, is the common salt- or alkali-grass (7)i.s/(W<7/s.s;2?w'aroducing a great deal of leafage, it is harsh and unjialatable and is refused by stock as long as other grasses are to be obtained. Sheep eat it more readily than other stock. It is abundant in the bad- land regions, and, as better grasses are usually scarce there, it is sometimes cut for hay. In localities where the land is be- coming "alkalied " through im- proper irrigation, this grass is spreading rapidly and often be- comes quite a pest. Montana sand-grass {Cala- magrostis montanensis) is the only representative of this genus that is of much impor- tance as a pasture grass on the dry prairies and foothills. Its distribution is rather local, but where it does occur in any quantity it is a valuable grass. It thrives on sterile, sandy prairies and hillsides and produces a large amount of leaves. It cures well on the ground, and hence affords good winter pasturage. It has not been reported south of the Big Horn Basin, in Wyoming, where it was found the past season in considerable abund- ance, particularly along the Gray Bull Iliver, on the west side of tlie basin. It was first observed in quantity at about 5,000 feet altitude, growing on dry, sandy tlats and bluffs, continued plentiful up to about 7,000 feet and then gradually became less and less common, disappearing entirely at 8,000 feet.

C, June 29^ 1S9S. Sir: I have the honor to tiausniit lierewith and recommend for pnblication as Bulletin No. 13 of this Division a report by Prof. Aven Nelson on The lied Desert of Wyoming and its Forage Resources, l)repared in accordance with the instructions of the Agrostologist. The Bed Desert region of Wyoming is a waterless and nearly treeless area. During the summer season it is practically uninhabitable, and a visitor at this time would doubt very much whether the region could be utilized in any way, especially as a stock range, but as a matter of fact this Red Desert actually affords excellejit winter pasturage. Here are fed the herds and tiocks of adjacent summer ranges, and many of the stockmen in northwestern Colorado, eastern Utah, and southern Idaho And in this region a desirable place to winter their stock, espe- cially their sheep. So far as I am aware, we have in this report the first presentation of the value of the Red Desert and other similar regions which occur in the interior of all large continents as ranges for stock, and the account given of the various forage plants npon which thousands of cattle and sheep graze during the winter months can not fail to be of interest. Among these plants which aftbrd nutri- tious food and apparently thrive in the driest climates and in strongly alkaline soil there are doubtless varieties that are well deserving of propagation, and by their cultivation land now totally waste may be rendered valuable. Respectfully, F. Lamson-Scribner, Ayroatologist. Hon. James Wilson, Secretary of Ayriculture. f I CONTENTS. Page.

Excluding from this rectangle the southwest corner, which 12 is fairly well watered, tbere still remains a tract approximately 85 by 130 miles in extent, embracing more than 11,000 scjuare miles, an area mncli larger than the State of Massachusetts. This vast area is included in that part of Sweetwater County east of Green liiver and certain portions of Carbon County west from the Platte. TOPOGRAPHY. The Red Desert is a high, undulating ]ilain or plateau, crossed and intersected at intervals by low ranges of liills (PI. 1, fig. 2). Occasional buttes occur, standing sentinel over the groui^s of hills that rim in the shallow basins or form the zigzag blufts of the many dry draws or the infrequent creeks. Far toward the northern boundary one sees the large, isolated butte known as Steamboat Mountain, and beyond this, on the horizon's rim, Antelope Hills, Green Mountains, and 1^'erris Mountiiins. This series, extending from east to west, forms the watershed on the south side of Sweetwater liiver and the northern boundary of the desert. To the north of the railroad are the Leucite Hills. IJlack Rock Butte and Orendo Butte are well known landmarks. Toward the east, as viewed from the heart of the desert, no relief appears, unless, perchance, a little toward the north one sees the tops of the Seminole Mountains. The southern boundary is made by ranges of hills and occasional wooded mountains, the view of which, however, is intercejited by the high blurt's that border the narrow valleys. On the western border, in the Green River bluffs, there is scenery of no mean type. Here buttes, long famed, overlook a valley that has had a reputation for grandeur and pictures! pieness for more tlian half a century. Crossing the desert from north to south, east of the center, is the height of land — the watershed of the continent Here are parted the waters of the Platte and the Green, liowing, respectively, toward the Atlantic and Pacific. The railroad intersects this line near Cres- ton, the exact point being marked by a signboard announcing this fact. From an altitude of 7,0.j8 feet at Creston, the land slopes away grad- ually toward the east and toward the west, but probably the average altitude for the whole region, if one takes into account the increased altitudes both in the northern and southern jiortions, is not far from 7,000 feet. The lowest altitudes are found in the narrow, bluff-bordered valley of Bitter Creek, which (PI. II, fig. 1), with an elevation of (;,7(K) feet at Bitter Creek Station, drojis to (i,077 feet at its junction with Green River near the town of that name. GEOLOGY.' The geology of the Red Desert is so varied that it is almost imi)os- sible to give a suitable brief descrijjtion. Considering that the desert ' The aiillior is iiidcOited to Prof. W. ('. Kiiij^ht for this summary of the geological features of Ibu lied Desert. 13 extends from the llawliiis uplift west to the Green Eiver, and from the Colorado line north to the bluffs south of the Sweetwater Eiver, it can best be described as follows : In the western portion there is an island- like mass of Cretaceous rocks surrounded by Eocene Tertiary beds. The Cretaceous exposure has been caused by an anticlinal fold whose western limit is some distance north of Salt Wells, and which extends in a southern direction nearly to the State line. The exposed core of this fold belongs to the Fort Pierre group, around which are extensive beds of Fox Hills and Laramie formations. (Ju the east Hank of this fold are the coal mines at Point of Pocks, Hallville, and Black Buttes; on the west are the celebrated coal mines at Rock Springs. To the west of Rock Springs the (ireen River Eocene ( ?) lies conformable ui)on the Larjimie. The Green River beds are made uj) of shales that are cut by deep and almost inaccessible canyons. The canyon of the Green River is at some points more than 1,000 feet deep. From Black Buttes eastward there is a synclinal basin that is cov- ered with Wasatch and Bridger Eocene, beyond which to the east the Laramie outcrops and extends from the State line north to Green Mountain, forming the eastern bouiulary of the desert. The Tertiary rocks covering the basins are quite level, and only form bluffs and escarpments occasionally along the railroad. To the north the country is level for from 30 to 40 miles to where it is hemmed in by high and precipitous bluffs. This rough country extends along the entire northern border. In the northwestern portion the country is very broken, and the castle-like buttes rise to a height of 2,000 to 3,000 feet above the level country. Oregon Butte is a famous old landmark, and is in reality a mountain made by erosion. South of the railroad the country is also broken, but is in no way comi^arable with the northern border. Another interesting feature is the eruptive overflows in the Creta- ceous rocks some 12 or 15 miles north and west of Point of Rocks. The main eruptive mass is known as the Leucite Hills, but there are numerous outlying elevations, such as Pilot Butte, Flat Top, and Black Rock Butte. SOILS. The soil of the Red Desert differs materially in the different parts of the region. It is, however, little more than the geological formations would indicate. Probably all the soils of the region must be charac- terized as saline, but the absolute amount of salts present in any par- ticular locality depends to a great extent upon the conformation of the surface. Through long-continued processes of leaching some forma- tions have lost and others have gained in salt content. Flats and basin-like depressions, receiving the drainage from the slopes, have become more and more heavily impregnated. The rainfall is too limited 14 to carry mucli of this salt away, so it is found incrnstiiig" the banks of the creeks and the margins and beds of the dry or sliallow lakes. Some of the abrupt slopes where lieaA^y winter snowdrifts lie are fairly free from injurious salts, and, judging from the a>ppearance of the vege- tation, have nearly normal mountain soil. Almost all the soils are poor in humus. The character of the soil as determined by constituents and water content gives five fairly distinctive formations. These may be desig- nated and characterized under the following divisions: Flains soils. — Surface more or less undulating, hence fairly well drained and losing slowly some of the soluble salts; soil consisting of clay, gravel, or sand, or these mixed in various i)roportions. Strictly speaking, it is not a true plain, but undulating or even hilly, with long gentle slopes leading to the basins and ravines. It includes all the land with sutticient slope for drainage. AlJcali soils. — Depressions or basins without drainage and flats adja- cent to creek beds; salt constituents increasing; soil, a mixture of fine clay and sand with the salts. Paludal soils. — Marshy bogs about springs and the margins of some of the few creeks; bogs of all characters from nearly fresh to highly saline or mineralized. Snowdrift soils. — The draws and abrupt slopes where snow accunui- lates and lies till late spring or early summer; gravelly or sandy soil, often of a loamy character, due to the considerable amount of decom- posing vegetation. Cedar Bluffs soils. — More or less abrupt slopes of shale, sandstone, or sand; soil inferior, but fairly free from salts; hence a somewhat varied, though stunted, vegetation. COMPOSITION OF ALKALI IN RED DESERT SOIL. The analyses^ of some representative soils from the desert show that they are among the most pronounced of the so called alkali soils, and that the principal salts are sodium chloride and sodium sulphate, while sodium carbonate, or black alkali, is not wholly absent. The following analysis of soil for the alkali contents from the desert 21 miles northwest of llawlins may be taken as fairly representative of the better soils of the Ked Desert in general : Alkali (water-soluble a.ilts), 0.12 per ceut of soil. Composition of alkali: I'er oent. .Sodiuin chloride 18. 5 Sodium sulphate :i7. 1 Calcium sulphate 35. 0 Magnesium sulphate 9. 4 100.0 ' The author is indebted to Prof. E. E. Slosson, chemist of the Wyoming Experiment Station, for the analyses, and to Professors IJutVuni and Kuight for one each of the samples. 15 A sample from Bitter Creek flats (second bottom land, on which salt- sages flourish) shows tlie following composition : Alkali (water-soluble salts), 0.<% per cent of soil.

In the bed of a dry pond a species of H^cirpus was growing where the surface soil contained more than GO per cent of soluble salts. CLIMATE. No reliable data are at hand from any locality within the desert either as to temperature or precipitation. On this account only general statements can be made, based upon limited personal observation and such information as could be gathered from the residents of the region. TEMPERATURE. The temperature is certainly very variable, rising during the long, clear days of summer to almost tropical heat and falling at night nearly or quite.to the freezing point. The dry, rarefied air of these high alti- tudes permits the free passage of the sun's rays, so that during still days 16 tlie plains and hills are subjected to almost blistering beat. IJadiation beiny the end of June n)ost of them are dead and blown away, only a few seed stalks lingering to tell the tale of what has been. FORAGE. The Eed J)esert is distinctively a stock region. Outside of the few- favored spots kept fresh by springs, there are no farms or gardens. From the 1st of June till the 1st of J^ovember the region is practi- cally devoid of stock of all kinds. With the coming of the snows the herds and flocks are worked back into the desert from the summer pas- tures in the hills and mountains. Through the winter and spring months thousands of head feed upon this rougli forage, the snowdrifts furnishing the water for all. The sheep herder in his wagon, also dependent upon the snows, guides his flock from district to district as new pasturage is needed. By the time the stock is taken to the sum- mer range the desert is barren indeed. Grasses, sage-brush, salt sage, white sage, rabbit brush, and even cedar boughs have been grazed so close that every edible sprig is gone. • AMOUNT OF FORAGE. The number of head of stock that the vegetation of a district will support gives some idea of the amount of forage produced. While giv- ing no facts in pounds or tons, yet relative estimates may be secured. 8in-ce the de.sert neither occui)ies the whole of auy one county nor is confined altogether to a single county, no statistics separate from those of the several counties which are in i)art within the de.sert can be given. The desert includes a large part Sweetwater County, a county some- what smaller tliau the whole of the desert. Tlie following ollicial fig- ures for this county, showing the number of head of stock supported, will, therefore, be a fair estimate for the desert as a whole. The figures are given for three years, in order to show what may be expected from its forage one year with another. Stock supported in Sweetwater County. Year. Horses. Mules. Cattle.

These are driven al(»ng slowly, the i)as- sage i)i' some of the Hocks through the <'ounty occupying weeks. During the winter months the adjoining counties, especially Carbon County, and the adjoining iStates — Colorado, Utah, and Idaho— gre.itly 21 swell the total of the stock that feeds within the desert. Flocks of sheep are brought in from all directions, and while of these there has not up to the present been any official record, yet enough is known to indicate that the estimates of the most conservative sheepmen are too low rather than too high. These place the total number of sheep in the desert, during some five months of the year, at 3()0,000 to 500,000. Some estimates for the winter of 1890-97 were as high as 800,000. Of the surrounding counties, Carbon- County sustains the closest relation to the Red Desert. A portion of the county is included in it, and its large flocks of sheep either feed in the desert proper or on vegetation similar to that of the desert during the winter season. The following official returns show what this vegetation will support. *S7oc/i: supported in Carhon County. Year. Horses. Cattle. Sheep.

The figures given for Carbon, Fremont, and Uinta counties are the actual assessments, and do not cover a considerable number that prob- ably escape enumeration each year, nor those flocks temporarily in these counties as " trail" sheep. 22 QUALITY OF FORAGE. The quality of forage, as Judged by results, is of the best. Horses, cattle, and sheep do well. If the winters are not too severely cold nor the snow too deep, all kinds of stock not only subsist upon these plants but actually remain in good Hesh throughout the winter. Of the grasses that cure upon the ground the Wheat-grasses are the most abundant, and these have long been known to possess high nutritive value. It is, however, the shrubby vegetation that furnishes the larg- est amount of valuable feed. Such plants are much more succulent than appearances would indicate. (Irowing on strongly saline or alka- line soils, the Salt-sages and many other plants take up these salts in such quantity that one readily detects them on tasting even a small fragment of a leaf. Stock feeding upon such plants secures the necessary amount of salt from the food, so that the salting of stock that must be resorted to dur- ing the mouths when the animals are feeding upon the mountain grasses is wholly unnecessary. MEANS FOR IMPROVEMENT OF THE FORAGE. How to improve the quality and increase the quantity of available forage in the Red Desert is a most diflicult problem. The soil condi- tions and water su])ply are such that not much may be hoped for through the expenditure of ordinary effort and means for the desert as a whole. Nor will any sudden or spasmodic ettbrt suflice. Only forces and plans operating for a number of years can be expected to give noticeably great results. It is very evident, however, that the forces now at work are tending toward improvement. According to the most reliable sheep men the same areas that twenty years ago would only support one sheep will now better support from tliree to live. This they attribute, to gain in the strength of the soil due to the accumulating manure. It seems probable that a more potent factor i.s found in the following: The vegetation chiefly depended upon for forage is composed of the large number of small shrubs of many kinds previously mentioned. The cut- ting down to the ground of such vegetation enormously increases the number of annual shoots. From winter to winter this shrubby vegeta- tion has l)een browsed down (doser and closer to the woody bases of the plants, until now the tender annual shoots are produced in much greater abundance. The effectiveness of this browsing is, of course, dependent ui)on the region being used as a winter pasture only, giv- ing time for growth and recovery each summer. Something can (;ertaiidy be done in a small but eftective way in the vicinity of those ranches that are now found within tlie region, or such as may yet be located. Salt-sages or other alkali-enduring vegetation, if the ground be seeded to them, can be made to yield much more 23 heavily thau at preseDt. For this purpose either native or valuable introduced forms (discussed elsewhere in this report) may be used. The native grasses also are worthy of trial. The writer has seen wonderful results from seeding the ground to sojne of these, especially the wheat-grasses, and this, too, where the water used for irrigation was far from the best and the ground strong with alkali. Further- more, the increase in the water supply is not quite hopeless. The region contains many natural basins in which, by the expenditure of a little labor in the construction of dams, much of the water from the accumulated winter snowdrifts might be saved for use later in the season. On the outskirts of the desert, the problem is much the same as in the greater arid west. Those measures which may be successfully introduced in other localities will be equally successful here. CHARACTERISTIC DESERT PLANTS. A question needing full investigation is the relation of plants to alkali or other salts in the soil. Practically all that we know is that some species have adapted themselves to endure or even thrive in soil containing greater or less amounts of various salts. Different species even in the same genus behave very differently in this respect; ibr example, Cheiiopodium albion L. seeks a soil free from salts, while for C. (jlauciim L. there can hardly be too much. If alkali affects a plant injuriously it seems to do so throughout its entire development. It has been shown that alkali retards germination or entirely prevents it in most seeds in direct proportion to the amount of the salt present.' Some families of plants have adapted themselves to saline soil more tiian others. Easily first in this respect is the goose-foot family {Clicnopo- diace(v). To this belong a large number of distinctively alkali plants, such as the Salt-sages, White Sage, Grease- wood, Russian Thistle, and Australian Saltbush. In regard to the question of largest representation by species of the families of plants found in the desert, the writer found on examining the collections that the family represented by the largest number of species is not necessarily the most characteristic of the region. The obvious vegetation, that which gives character to the landscape, can be included in a half dozen genera, Artemisia, Tetradymia, Chri/so- thaniHUs, Atrijdex, Sarcohatm, and Ar/ropyron. Kemove all the plants belonging to the three families, Gompositcc, Chenopodiacew, and Chutnii- new, and the region w^ould look like a true desert. Many other families are better represented in number of species, but the individuals are either small or scattering, and bear the same relation to the great mass of vegetation that the occasional weed in a well-tilled field bears to the main crop. The plants of the following list are worthy of special note. It is 'Bull. 29, Wyoming I'xperiiuent Stition. 24 intended to include only tliose tliat are of first importance either because of the large amount of forage produced or because of tbeir great nutritive value and those that give promise of good results under cultivation. They are here arranged rather in the order of importance for the two regions: (1) Vegetation of the desert, or winter, range (see PI. 1); and (2) vegetation of the hill country, or summer, range (see PI. IT, tig. 2). VEGETATION OF THE DESERT, OR W^INTER, RANGE. (1) The Salt-Sages.— The salt-sages rank first in the amount of for- age produced, and, judging by the number of cattle supi)orted on the winter pastures and the reported fine condition of the stock, these plants possess high nutritive value. NuTTALL's Salt-sage {AtripUx nuitalUi S. Wats.).— Of the several species, this stands first in the matter of distribution. It is found nearly everywhere except on the most pronouncedly alkali ground. It belongs not only to this desert and this State but is the most generally distributed salt-sage of the entire arid west. It is the sheepman's most highly-prized winter forage, and certainly here furnishes one half of the whole supply. Sheep thrive upon it both when it is green and also in the winter after it has cured upon the ground. It is a perennial with a woody base, calculated to endure severe pasturing and much trampling. It is each year eaten down to the ground, leaving only the woody base. It produces seed in abundance, which is greedily eaten, and this probably accounts for its high nutritive value. It seems unsuited for cultivation, except where a i)erennial ])asture is desired, on account of its woody char- acter and slow growth, but where well established it is a source of much feed for all kinds of stock and should not be carelessly destroyed. Nelson's Salt-sage {Airiplex pabnlaris A. Nels.).— This new species seems to be a form of great promise as a forage plant. Like the preceding, it is a perennial, but the woody base is almost wholly underground. The herbaceous stems are i)roduced in much greater abundance, forming often a close, continuous, erect growth. So far as known it is not widely distributed, being confined to strongly saline areas, such as the Hats adjacent to Bitter Creek and its tribu- tarii's and the dry beds of alkali basins. It fruits freely, makes a considerable annual growth, and is certainly worthy of trial with a view to forming a permanent i)asture on otherwise valueless alkali ground. Its habit of growth would also make it i>ossihle to harvest it by the methods applicable to the grasses. Slieepmen unite in ])ronouiiciiig it prime forage. TuMnLTN(^ Salt-sage {Airiplex rolutans A, Nels., PI. Ill, fig. 2).— This heretofore overlooked annual may prove a more valuable ]>lant for certain alkali soils than any of the f-ireign species that have been so highly recommended, it is a plant of rank growth, and 25 wheu not crowded, forms in one season a compact subspherical mass 3 feet or more in diameter. If left to mature on tlie ground the slender tap-root breaks in tlie autumn and tlie plant becomes a tumble-weed. After that time it bas probably little nutritive value. If it is ever utilized as a forage plant it must be harvested shortly before maturity. If closely grown this would not be diffi- cult with ordinary machinery. It produces a great abundance of seed that could be thrashed out with very little trouble. Spiny Salt-sage {Atriplcx confcrti/oUa S. Wats,). — To see this spiny shrub one would hardly think of it as a valuable form of forage, yet sheepmen look upon it as such. They say there is no fault to be found with it except that "there is not enough of it." It is popu- larly known as Shad scale. It belongs peculiarly to the desert region, where it is eagerly sought in late spring for its tender shoots and leaves. The large quantities of leaves and fruits produced during the summer months are mostly dropped before autumn, but are collected by the winds into little piles under the shrub or in the little hollows of the plain. These the sheep eagerly seek, so that where a band of sheep has fed it is difficult to find either leaves or fruit. (2) The Sage-Brushes {Artemisia). — The amount of sage-brush con- sumed in the desert is simply amazing. Sheepmen and herders say that for sheep a straight sage-brush diet at certain times seems to "meet a long felt want." Whole bands will leave all other for- age and browse sage brush for a day or two at a time, after which they will not touch it again for some days, or even weeks. This is especially true of the common sage-brush {Artemisia tridentata Nutt.), while some of the other species are so much sought after at all times as to need special mention. Bud-brush, Bud-sage {Artemisia spinescens Eaton). — This is the sheep- man's "bud-brush." It grows to the height of only a few inches from strong, woody, underground parts. It puts forth numerous leafy stems, profusely covered with clusters of yellowish flowers. The large, bud-like clusters of flowers have suggested the common name. It develops early, being at its best by the end of May. It is said that sheep run hastily from clump to clump in search of this succulent morsel. Silvery-sage {Artemisia cana Pursh). — This in quality probably does not differ materially from the common sagebrush, but, in propor tion to area occupied, it produces much more forage. It is found chiefly in the alluvial soil on the banks of streams. Its forage value is due to the production each year of a very large number of long, slender, tender shoots, which are eaten at intervals, as before stated. (3) Wheat-Grasses { A gropi/roti).— For quality these grasses would take first place in the desert forage, but the amount is quite limited. 26 Tliey cure readily on the ground, and remain more nearly intact throughout the winter months than any of the other grasses of the region. The species of most importance are given as follows: Slender Wheat-grass {Agropyron tenernm Yasey). — This wheat- grass is very generally distributed throughout the area. It is found in all parts of the desert, as well as in the better soils of the summer range. It grows in dry, poor soil, but thrives better in good soil, and responds readily to cultural advan- tages. A moderate amount of water in irri- gation produces best re- sults on this grass. It will hardly stand flooding at all. For pasture pur- [>oses there are grasses that will endure more hard treatment than this, but as a meadow grass it must be given first place. It often forms a close, uniform growth that yields as much per acre as an average field of timothy. Considering its high nutritive value, no more profitable grass can be found than this for the desert region, especially on saline soil and where the (J uantitj^ of available water is limited. While not seeding very freely, the re(iuisite amount for sowing can easily be ob- tained after the first crop has been harvested. It is easily thrashed out in a machine, or maybe Hailed out if no better method is at hand. Seed of tliis grass is now on the market. Colorado Blue-stem, Western Wheat-grass {Af/ropi/ron sjiica- tioit S. & S., tig. 1). — This grass is (capable of enduring drought to a remarkable degree. Naturally, however, it nuikes a very sparse growth. Distributed rather generally throughout the region, it is found occupying the driest banks ami bench lands. It is capable of rank and dense growth under favorable conditions, as sho\\ n in Fl(i. 1. — Wcstcni Wlicat Kiass {Aijinjiiiron njn'ratinii) I'luiily };lmii('S; b, llori'is. ", 27 irrigated meadows, where it occurs as the principal grass. r>est results will be secured on second bottom lauds with moderate water. Flooding should be avoided. (4) Indian Millet {Eriocoma cusimJata Xutt,, lig. 2), — The value of this grass has been greatly underrated. It is not only widely distributed, but manages to make a fair growth in desert places, where other grasses are almost wholly absent. It develops early and keeps in fair condition throughout the season. Under favorable conditions it grows to a good size, but even dwarf s])('cimens fruit freely. A 1 1 k i 1 1 d s of stock relish it, but horses are particularly fond of the seeds, and will go from bunch to bunch cropping out the heads. On sterile and stony ground it may prove more profitable than any other that could be sown. (5) Giant Rye-Grass (/•;///- mns eondensatus Presl). — This is worthy of note be- cause of its conspicuous uess rather than its great forage value. To the casual observer this is the grass that would characterize certain lo- calities. It would be thought of as a part of the general relief of the re- gion. Thedensebuiu'hes, sometimes 5 to 7 feet in diameter and G feet high, stand out very promi- nently on otherwise naked slopes. It is found all the way from creek banks to the deep "draws" and slopes where snowdrifts accumulate. As forage it is eaten to some extent while young, but becomes unpalatable and harsh as it matures and cures on the ground. It is considered valuable as fodder if cut and cured before it matures. In this condition it is fed to advantage to cattle and horses through the winter months. Possibly if sown thickly and harvested early it might be profitable on account of the quantity produced. Fig. Indian Millet (Eriaturtiia cuspidata) : a, spike- let; b, iloret. 28 (6) Desert Juniper [Juniperus lin'ujlitii A. Nels.). — To list a tree of any cliaracter as a noteworthy forage plant is at least a little unusual. This scrubby, shrub-like juniper,' or, as it is usually called, "bluff cedar,'' has, however, saved many a flock of sheep from extinction. During some of tlie terrible blizzard-like snow- storms that occasionally occur and last for two or three days the only available forage consists of the branches and tops of this Junii)er. The experienced herder keeps worliing the slieep about, so as to have them on top of the snowdrifts instead of under them. Gradually a trampled-down yard is formed, which, if it be among the cedars, will enable him to hold his flock for some days safely. "Cedar boughs" are not refused under such circumstances, and if not very nutritious, they at least fill the stomachs of the hungry animals. VEGETATION OF THE HILL COUNTRY, OR SUMMER, RANGE. A complete discussion of the forage of tlie vast area which constitutes the summer range of the flocks and herds that winter in the desert is not called for in this report, and would necessitate a more critical investigation in the field of the jilant formations that characterize the different areas than they have yet received. Enough is known, how- ever, to enable one to state the character of the forage with a degree of certainty. It may be said then, first of all, that the summer forage is distinct- ively herbaceous, strikingly in contrast with the more or less shrubby vegetation of the desert; that it consists primarily of grasses, sedges, and rushes, in contrast with the woody jflants of the winter range. The Slimmer range consists of the monntainous and hilly areas on the outskirts of the desert. It does not include the impenetrable and rugged fastnesses of the higher ranges, such as the Medicine l>ow, the Wind Kiver, and the Uinta, but mountains of medium elevation, with rounded slopes, only partially wooded, and well watered Avith springs and creeks. The timber upon such is oi)en, or, if dense, is interspersed with i)arks or meadows of most luxuriant growth. Here is a grove of quaking asjten, there some scattering i)ines, and yonder a spruce- covered summit. In the narrow valleys springs and snow-fed stream- lets are found on whose banks occasional cliim])s ot willow or alder occur. In tlicse regions grasses flourish as they never do on the ]»]ains. The better soil and the lre<|uent snnunei' showers furnish the conditions Cor luxuriant growth. Of grnsses there are many genera, of which the fcjllowing are the more valua))le: Tiie Spear grasses {Fon) are easily first as to number and value. After these come a number of groui)s, all of great value, or at least containing one or more valuable species. Among these are the Brome- grasses {Bromus), Wheat grasses (Af/ropi/ron), llye-grasses {Eli/mn.s), Dropseed grasses {tiporohoUis)^ Timothy (I'lilenui), Manna, or Reed, 29 Meadow-grasses {Panicnlar'm)^ Bhie-joiuts ( Galamagrostis), Hair-grasses {Deschampsia), and Bent grasses (Agrostis). {D The Spear-Grasses {Poa species). — The Spear-grasses, of which :here are many valuable species, are most abundant in the hills and mountains and along water courses, but they are not absent even in the desert. In looking over the large list of species secured and the held notes upon them, I find myself unable to fix upon any one as preeminently the most promising or valuable. Some have a wide and general distribution, but are of scattering growth. Others, more local, grow luxuriantly, and for their par- ticular localities stand first. All must be reckoned as pasture grasses of first importance. Some are meadow grasses of impor- tance, especially in native meadows, but for cultivation for hay greater returns can probably be secured from other kinds of grasses. Among those of very general distribution may be men- tioned Bunch-grass (2'oa bneklcydna), Alkali Blue-grass (P. ./w/ici- folia), Smooth Bunch-grass {P. laevigata Scribn.), Wood-Meadow grass (P. nemoralis L.), Kentucky Blue-grass {P.pratensis L.). The last mentioned is undoubtedly native in a large part of the North- west. In many native meadows and pastures, along water courses, and in the foothills it forms an important part of the sod, and occa- sionally makes quite a rank growth. Among the more local but very valuable Spear-grasses are Western Blue-grass [Poa arida Vasey), Fowl Meadow-grass {P.Jlava L.), Shiny Bunch-grass (P. Incida Vasey), Sheldon's Blue grass [P. sheldoniVsksey), Mountain Meadow-grass (P. rejiexa Vasey & Scribn.), and Wyoming Blue- grass (P. whceleri Vasey). Of these last P. slieldoni appeared the most promising, as seen in the field. It is one of the most impor- tant grasses of this range, forming a large percentage of the forage on the park meadows among the hills. It is freely eaten by stock and vseems to hold its own under the severest pasturing. (2) The Brome-G-rasses [Bromus). — The several species of this genus are hardly thought of as pasture grasses on account of their rank growth. Some of the mountain species, however, are valuable as summer forage, while they are also plants of great i)romise for meadows. Some of the species are well known and have been suc- cessfully introduced into many localities. It seems possible, how- ever, that the best are yet to be introduced. Of the eight species collected in the area under consideration, a form common in the Sierra Madre Mountains and their westward extension on the Col- orado-Wyoming line seemed by far the most promising: Large Mountain Brome Grass {Bromus multiform Scribn.). — This is a most striking grass, one that attracts attention at once in a region where fine grasses are the rule. This is the grass that characterizes the locality. To the general observer this would be recalled as the grass not only peculiar to but distinctive of the region. The miners think of it as the feed that their horses sub- 30 sist upon. It grows upon the hillsides among the fallen timber. It is hardly abundant enough in any locality to form a continuous meadow, but if cut would, on account of its size, supply a fair crop of haj^ Horses eat it with avidity and seem to do well upon it. They prefer it to the other abundant grasses of the locality. It was collected at altitudes between 9,000 and 10,000 feet in the parks and open woods, localities in which vegetation hardly starts before June, for almost uutil that time snow covers all. In conse- quence of its habitat it matures late, but if introduced into lower altitudes it would undoubtedly prove as early as other grasses of its kind. It grows to a height of 3 to 4 feet, produces an abun- dance of leaves, and if it would thrive under cultivation as well as in its native habitat it would give an enormous yield. (3) Dropseed {S2)orobolii.s dipmipcratHS Scribn.). — This grass grows along streams, in the foothills, and open parks in the mountains, and even in some of the draws in the desert. It forms a close dense sod, especially where it is freely pastured. On mnnjM)ottom lands it is the prevailing grass. All kinds of stock seek it out, so that it is difficult to find mature si)eciniens except on inclosed grounds. It seems that it might be introduced with profit into most pastures not only in the mountain regions but generally else- where as well. It might also jnove valuable as a lawn grass in places where water for irrigation is limited or in lawns that have to endure much trami)ling. It is possibly a little harsh for this purpose, but frequent catting would thicken up the sod and reduce the harshness to a mininum. (4) Reed Meado^v-Grass {Panicularia americana MacM.). — Among the several nianna-grasses this seems by far the most valuable for this region. It is probable that its value as a meadow-grass is not appreciated. For exceedingly wet ground it must prove especially desirable. Here is a grass that will stand Hooding. It is adapted to land that is submerged during the growing season, and only needs it to be dry in time for harvesting. It is quite abundant in some localities, and if it were introduced to take the i>lace of the sedges and rushes that so abound in wet or Hooded meadows there would be a distinct gain in both quantity and quality of the hay. On Mr. Jacob Johnson's ranch, where it was particularly observed, it occupies many acres. It was being mown at the time, and was accounted one of the most valuable hay grasses. Horses relish it greatly. They were seen wading in nnul and water to their knees to secure this when other excellent grasses were superabundant. (5) Redtop {Af/rosti.s (dlxi L.). — Presumably introduced and undoubt- edly sown in some meadows, but so widely distributed and in such out-of the-way ])laces as to iiulicate that it is also indigenous in the .Stute. It thrives in low, wet ground, and will stand Hooding much Ix'ttei- tiiiin most of the other valuable grasses. It forms a large l)ercentage ol the meadow glasses on the l>ear Kiver bottoms. To 31 substitute it for the sedges aud rusbes in tlie meadows of tbe Laramie river would be tbe part of wisdoni. With this aud the tall I'eed ]\Ieadow grass the wettest ground could be utilized. (6j The Sedges [Care.r). — Of this genus the region affords a very- large number of species. They are of varying- abundance and value, but it is hard to select, even after observation in the field, the most profitable. Many of them are cut for hay and certainly have nutritive value, but they are hardly to be compared to the better grasses. In nniny fields, however, they have almost re- jjlaced the grasses owing to over irrigation. The senseless manner in which the water is applied to some of the grass lands must be attributed either to ignorance or indifference. Early in the spring, while the ground is still wet aud cold, the lauds are submerged and kept in that condition through the season, and are only drained in order that the mowing machines may be taken into the fields. A few seasons of this kind of treatment gives the land over to sedges and rushes and makes it reclaimable with the greatest dif- ficulty. For lands that are natnrally wet some species of Carex may be found better adapted than the true grasses, at least in cer- tain kinds of soil. Among those that are peculiarly adapted for hay purposes may be named Carex athrostachya Olney, C. /estiva stricta Bailey, G. lanuginosa Michx., (7. marcida I5oott, C. nehras- Jcensis Dewey, C. trichocarpa aristata Bailey, and C. utriculata minor Boott. The dense growth of leaves in C. hinug'Diosa and C. trichocarpa aristata makes them particularly desirable for hay. The latter yields enormously in some of the fields on the Laramie bottoms. For a pasture sedge there is nothing to compare with Carex media, dejiexa Bailey. It belongs in the mountains, in the open parks, and on the ridges at 9,000 feet and upward. In such places it forms close mats several feet across, and these in places almost touching each other. It grows to only a few inches in height, bnt produces an abundance of leaves and fruited stems that are much sought after by stock of all kinds. Where it is accessible to stock it is hard to find matured, or fruited, speci- meus. There are forage ])lants of more or less value among the rushes, the legumes, and in a few other groups, but these Avill be noticed in their order in the systematic list. LIST OF THE FORAGE PLANTS OF THE SUMMER RANGE. The following grasses and forage plants were collected on the sum- mer range (the hill country bordering the desert) during the season of 1897: GRASSES. Pauicum virgatum L. (Switch-grass, fig. 3).— A grass with rather rigid, waud-like, few-leafetl stems, 20 to 30 inches high, the fruiting pedicels slender, spreading, the spikes (if few luit lariie seeds. Probalily rare in the State, as it has been secured only near the .Nebraska border. IMue Bluffs, July 6 (362G). 32 i^ Phalaris artindinacea T.. (Rked Can.\kv-(;i;ass).— A tiill, luiiidsomo grass, 3 to 5 feet Li^b, willi ;imple, fiieen leaves and loiij;, close jjauides. 1 1 occurs in wet ground along ditches and creek banks, in shallow bogs and ponds; nowhere observed in abundance, and therefore in its nativ*^ state of little economic importance. .lobnson's Kanch, Big Jjarainic, August 7 (3910) ; Grand Encamp- ment Creek, August 13 (3987). Savastaua odorata Scrihn. (Seneca-grass, fig, 4).— A small grass, 6 to 12 inches high, with largo heads; whole plant emits a delightful fragrance. It occurs in cold, swampy ground from middle to high altitudes, some- times in such quantity as to constitute a perceptible part of the forage. Willow Creek, May 22 (2908). Aristida fasciciilata Torr. (PuR- I'i,eI>eari>-c;kass). — A closely tufted grass, with slender, very numerous stems, short, sh'Tider loaves, the heads with long, divergent awns. Not of frequent occurrence in the State, hut in one locality very abundant, where it occui)ied the dry foothills, especially the loose, broken ground. Pine Bluff's, July 6 (3617). Stipa Columbiana Macoun (Co- lumbian Needle-grass). — A bunch grass with numerous long leaves, the ui)per part of the stems naked and hearing a long i)aniclo with awns of moderate length, 2 to 3 feet high. It is a rare grass and was sparingly found in scat- tering bunches in the o])en woods on the Medicine Bow River, August 20 (4074). Stipa comata Trin. vV Rupr. (Neeole-grass). — One can scarcely think of this tufted grass, with its long, twisted awns and barbed seeds, as anything butai»est,but.stock- nien assert that it is valuable for pasture before it heads, and that if cut after the "seeds" have dropped it forms a good quality of hay. It is very abuiulant on the plains and in the dry foothills of the eastern part of the State. Pine Blutl's, .July 5 (3G03). Stipa nelsoni Scribn. (Nelson's Nkedi.e-gisass). — This grass belongs to the sum- mer range especially, but it was also secured within the l\cd Desert. In the wooded, mountain areas it attains to greater luxuriance and is of more frequent occurrence. Woods Creek, August 9 (3963); Battle Lake, August 17 (1059 and 4060). Fi(i. 3.— Switfh-graas (Panicum virijatum) : a, apiki^ets b, Htaininalo lioret ; r, floret ; d, auterior view of saino. 33 Stipa minor (Vasey) Scribu. (Pukplk-top Needle-grass). — A bunch grass with nnnierons slender root leaves, slender, somewhat wiry stems terminated by long heads with divaricate and Aariously twisted or bent awns of moderate length. Theroot system, with the dead leaves and stems of the previous year, forms a firm, harsh mat, from which the new stems and leaves arise, 15 to 2.5 inches high. It seems to belong to the mountain slopes in the region of permanent winter snows, especially among the fallen timber on partially open hillsides. It is not known whether the awns are such as to lessen its forage value. "G." Summer ranch, July 23 (3828); Battle Lake, August 16 (4026). Stipa tweedyi Scribn. (Tweedy's Stipa). — A bunch grass of spreading habit with long, gen- iculate, bent awns ; stems 20 to 30 inches long. In general appear- ance it much resembles S. comata, and its forage value may well be compared with that. Sheep Mountain, July 3 (3297). Stipa viridula Trin. (Feather Bunch-grass). — A tall, coarse bunch-grass, with a long, close panicle, awns bent, of moderate length, seeds falling early. It occurs in the eastern part of the State on the dry, open plains, but never iu any great abun- dance. Pine Bluffs, July 6 (3613). Oryzopsis micrantha Thurb. (Small - flowered Mor xtain Rice). — A rather handsome, slender, spreading grass with long, slender root leaves, pan- icles loose and spreading, the spikelets on slender, divaricate pedicels, mature seeds large. This was secured but once, among the broken rocks in the bottom of a dry canyon. It must be of excellent quality, and if it Avould thrive under cultivation it would form a valuable addition to our forage plants. July 6 (3615). Eriocoma cuspidata Xutt. (Indian Millet).— A valuable grass of very wide dis- tribution in the State. Pine Bluffs, July 5 (3606). Muhlenbergia comata Bentli. (Hairy Muiilenuergia). — A smooth perennial with rather scanty leaves, 1 to 2 feet high, heads spike-like, soft-hairy, the awns short and fine. Not plentiful; usually on river bottoms and most frequently among the stones on the low banks. Evanston, July 28 (3857); Grand Encampment Creek, August 13 (3994). Muhlenbergia gracilis breviaristata Vasey. — Growing in tufted, mat-like clumps; leaves mostly radical, short; stems slender, 6 to 12 inches high; heads large for the size of the grass, awns very short. It occurs in the hills, mostly on the naked 3018— No. 13 3 Fig. 4. — Seneca-grass {Savastana odorata) : a, spikelet; b, rtorets; c, palet; d, pistil. Pine Bluffs, 34 summits and ridges, sometimes in sufficieut abundance to constitute an appreci- able part of the forage. Head of Pole Creek, July 22 (3431). Phleum alpiuum L. (Alpine Timothy).— Very similar in general appearance to the ordinary field timothy, except that it is somewhat smaller. Il is found on moist slopes and in the valleys at 8,000 to 11,000 feet, often constituting a large per- centage of the most valuable forage. Beaver Basin, July 22 (3816) ; Battle Lake Mountain, August 17 (4050). Alopecurus geniculatus fnlvus Scribn. (^Maksh Foxtaii,).— A succulent grass with an abundance of soft leaves, forming small, usually decumbent bunches, stems 12 to 20 inches long. It fre quents wet ground, especially creek banks and shallow stream beds, Avhere it forms tufts among the cobblestones. It is relished by stock, though it is probably rather watery in its composition.

(Mountain Foxtail, tig. 5).— A valuable grass in the moun- tain meadows and parks. Bat- tle Lake, August 10 (4017). Sporobolus airoides Torr. ( Fine- top Salt-gi:as8, lig.fi). — This grass forms large mats or sometimes considerable areas of harsh, raised sod, the short, stiff root-leav(!S and wiry stems giving it a disa- greeable feeling to the touch ; 1 to 2 feet high, producing a large, widely spreading pan- icle. In spite of its stiffness, on the open bottom lands stock keep it well eaten down, and it is difficult to find fruited specimens. Little Laramie River, July 24 (.34.52) ; Tine Bluffs, July 7 (3619); Granger, July 30 (3877). Sporobolus asperifolius Thurb. (Rough-leafed Salt-gijass, tig. 7).— Harsh but sleiulor leaves and stems; 9 to 15 inches high, the numerous capillary i)edice]s of the panicle widely spreading. Probably of little value, though it may furnish some of the summer pasture on tiio bottom lands where it occupies the drier knolls, or more rarely is intermingled with other grasses on the lower, moist ground. Granger, July 30 (3876 and 3889). Sporobolus coufusus Vasey (fig. 8).— A small form growing in little tufts, the stems and leaves almost hairlike, and the delicate panicle widely spreading, 3 to t) inches high. \ot oliserved except on stony or gr.ivelly stream banks, where it forms a scattering, inconspicuous growth. Laramie h'iver, July 12 (3361); Grand Encampment Creek, August 13 (3990). Fig. 5.— Mountain Foxtail {Alopecurus occidenlalig) : a, spikelet; 6, fioret. 35 Sporobolus cryptandrus A. Gray (Sand Dropseed). — A tufted form with spread- ing-stems, 12 to IS incbfs long, occurring on sandy knolls and ridges; usually of very scattering growth, so that, thougli it is a nutritious jjasture grass, it is of small economic importance. Hillsdale, July 7 (3660) ; Laramie, July 20 (3417). Sporobolus depauperatus Scribn. (Dkopsekd). — Somewhat tufted, but still form- ing a continuous sod, stems and leaves slender, 6 to 12 inches high. A most excellent pasture giass. Centennial Valley, July 2 (3274); Evanston, July 27 (3841); Granger, July 30 (3883); Johnson's Ranch, August 8 (3901); Grand Encampment Creek, August 13 (4002); Wagon Hound Creek, August 21 (4403). Sporobolus simplex Scribn. — A tiny alpine form, growing in little tufts, or sometimes as small patches of uniform sod; the fruiting heads slen- der and few-seeded ; the fine root-leaves numerous and nearly as long as the capil- lary stems, which are 2 to 4 inches high. It occurs on the uaked slopes in the vicinity of the permanent winter snow banks. Battle Lake Mountain, August 16 (4011). Agrostis alba L. (Red top, Herd's-grass). — This well- known grass occurs through- out the valleys of the whole region investigated. In many places it has no doubt been introduced, but in some of the localities where it was secured it must have been in- digenous. It prefers wet ground, and thrives im- mensely under irrigation. In some of the valleys it is con- sidered one of the important meadow grasses, as, for in- stance, at Evanston, in the Bear River Valley. Hills- dale, July 7 (3663); Evans- ton, July 27 (3832 and 4444) ; Granger, July 30 (3888); Grand Eiuampment Creek, August 13 (3995). fig.6.. Agrostis asperifolia Trin. (ROUGII-LK AFED BeNT- GRASS). — An erect grass with long heads and numerous, ample leaves. It prefers wet ground, such as the banks of streams, partially shaded l>ottom lands, and more rarely boggy ground. It is a valuable constituent of the forage in such situations, and forms a part of the hay in wet meadows. Evanston, July 28 (3856) ; Woods Creek, August 9 (3964). Agrostis scabra Willd. (Rough Hair-grass). — Erect, with slender leaves and stems and narrow, or, in older specimens, widely spreading panicle, the pedicels extremely long and hair like. It forms a small part of the native grasses on most of the bottom lands; occurring as scattering specimens or small clumps, most frec^uent in the loamy soil of stream banks, probably of little value, but -Fine- top Salt-grass (Sporobolus airoides) : a, spike- let; 6, floret. 36 on open grounds grazed down with the other grasses. Head of North Vtrniilion Creek, July 20 (3792) ; Evauston, July 28 (3851) ; Battle Lake, August 16 (4021). Agrostis tenuis Vasey (Slknder Haiu-gkass).— Resembling the preceding, but smaller, the panicle and its i)edicels shorter and less spreading. Collected but once, in ground then fairly dry, hut probably boggy earlier in the season. Low (6 to 12 inches high), and in small quantity. Battle Lake, August 1G(4014). Agrostis huniilis Vasey (fig. 9).— A bunch grass of very small proportion, only 3 to 5 inches high; seemingly very rare; only one small bunch secured on an alpine summit near a snowbank. Battle Lake Mountain, August 17 (4070). Calamagrostis hyperborea americaua Kearn. (Sano-grass; Ykllowtoi-).— A tall fine-looking grass, with close cylindrical heads, often 3 to 4 feet high. In this range it seems to be found in a-bun- dance in wet draws and on banks where seepage water is abundant. It often forms a close, even growth, but as it requires so much water it can not be utilized, except on tlie wettest ground, as a meadow grass.

Calamagrostis cauadenfis (Mx.) Beauv. ( Bu'e-joixt grass). — Stems and leaves stouter than in the preceding, heads close and full, 2 to 3 feet high ; in- frequent, usually in wet places or on creek banks. Head of Pole Creek. .Inly 22 (3437). Calamagrostis canadensis acu- minata Vasey (Mountain Blue-joint). — Much resem- bling the preceding in general appearance; in age the pani- cle is loose and sitreading. It is the commoner form of this range, occurring both in t>pen and in partially shaded ground. Its luxuriant growth and am)>lc leaves suggests that it may be valuabic under cultivation. In one mountain locality it formed a luxuriant and continuous growth among the fallen timber. Johnsons Kanch, August 9 (3905); Woods Creek, August 10 (3946); Battle Lake, August 16 (4018). Calamagrostis moutanensis Scribn. (Montana Bluk-.ioint).— A small erect form, with close cylindrical heads, rarely more than a foot high. It occurs on dry or even on rocky slojjes, and on the drier parts of th«' bottom lands as scattering spec- imens or irregular i)atches of various sizes. It must be considered as a pasture grass of some value. Horse Creek, July 13 (3381) ; Big Creek, August 11 (3970).

(Puri'LIsii Reed-grass, fig. 10). — A mountain form, 12 to I'U inches high, with amjjle root-leaves and close cylindrical heads. The specimens secured formed close hunches on the rocky clitfs and on the highest summits; not abundant. Battle Lake, August 16 (4047 and 4056). Calamagrostis scribneri Beal CScribxer's Reed-grass). — Erect and stout, with a wealth of long broad leaves and ample heads 3 to 4 feet high; the handsomest grass of the genus, often making a dense close growth that yields an abundance of hay, presumably excellent, though the leaves are somewhat scabrous to the touch. It jtrefers wet ground, but thrives on the bottom lands anywhere or even on the lower slopes of the adjacent hills. Johnsons Ranch, August 9 (3920) ; Woods Creek, August 10 (3954) ; Grand Encampment Creek, August 13 (3989) ; ^ledicine Bow River, August 20 (4082). Calamovilfa longifolia Scribn. (Big Sand-grass). — A coarse grass occurring in occasional clumps, 2 to 4 feet high. Rare in this range and probably confined to the eastern part of the State, where it occurs on the dry sandy plans or hill- sides. Hillsdale, .July 7 (3G(J6j. Deschampsiacaespitosa Beauv. (Tufted Hair-grass). — Uensely tufted, with an abundance of long root leaves, the slen- der stems exceeding the leaves and ter- minating in large, loose, spreading panicles. It is of frequent occurrence throughout this entirf range, occurring on all the streams, in the mountains on all the moist slopes, and even on alpine summits. Little Laramie River, July 4 (3337); Pine Bluffs, July (5 (3623); Bea- ver Basin, July 22 (3817); Evanston, July 28 (3860) ; Grang.-r, July 30 (3890) ; Woods Landing, August 7 (3904) ; Battle Lake, August 16 (4008). Tri.setum subspicatum Beauv. (Downy Oat-grass). — Usually growing in small tufts, which are irregularly scattered on mountain slopes or more rarely in the valleys, root-leaves abundant, the up- per stem nearly naked and bearing a short, cylindrical head, with soft, di- vergent awns. As a pasture grass it has value in proportion to its abun- dance. Battle Lake Mountain, August 17 (4045 and 4061). Danthouia californica Boland. (Cali- FORXiAX Oat-(;rass). — Decumbent at base and somewhat spreading or de- clined in habit, stems leafy, 20 to 30 inches high; panicle small. It is certainly very rare in the region, for which reason its forage value need not be taken into account. Observed but once as a scattering growth in an aspen grove in a moist valley. Greentop, June 29 (3253). Danthonia intermedia Vasey (Mountain Oat-grass). — An erect, handsome grass with well-developed heads, 15 to 25 inches high. It occurs in small patches as an open sod in the margins of the woods or in the small parks in the mountains. In many x)laces it is sufficiently abundant to have much value as a pasture grass. Battle Lake, August 17 (4037 and 4055) ; Woods Creek, August 9 (39.59). Danthouia parryi Scribn. (Parry's Oat-grass). — Somewhat similar to the preced- ing, but lower and with looser heads, more inclined to be tufted at base. This Fig. 8. — tSporobolus con/usus : a, b, c, npikelets; d, floret. 38 also is of rare oecnrrence, and is met with only in the liills s.i far ns ohserved. Secured on open hillsides, where it oocnrred iu small patches, grow inj; on a soil of disintegrated granite. Greeiitop, June 29 (3245). Spartina gracilis Trin. (Si.EXDER Cord-GRASS, tig. 11).— A perennial from tough underground root-stocks, rather rigid and woody, hut not harsh; possibly of some value when young. It occurs as a scattering growth on sandy, alkaline soil on creek or pond hanks.

(IW.ack (;i:ama).— l^omewhat tufted or matted, )>ut often a fairly uniform growth over sevei.il rods of ground in a place, the numer- ous leaves are largely basal, tin; slender stems w hich Ik ar the one sided heads, 10 to 1« inches high. This is j)reemiiiently the grass of the jdains, occurring in greater or less abundance every where on the arid pasture lands. It is of especial 39 valne as a pasture grass, but furnishes a part of the hay on the drier second hot- torn meadows. It has the reputation of being very nutritious, and the condition of the stock pastured upon it bears out this idea fully. Laramie Plains, July 19 (3409); Pine Bluffs, July 6 (3619); Hillsdale, July 7 (3658); Woods Landing, August 7 (3909). Beckmannia erucaeformis Host. (Slough-grass, fig. 12).— A grass of the bogs and of the margins of ponds and irrigation canals; erect, well leafed, heads long and slender, seeds flat and large, falling early and leaving the raohis bare almost as soon as it is mature. Probably of no special value, but in very wet ground it often constitutes a percep- tible part of the plants that are cut for liay. Much of it, however, can not be utilized, as it grows in places where it is not ac- cessible until so late in the season that it has lost its value for any purpose. North Fork Vermilion Creek, July 19 (3763) ; Ev- anston, July 27 (3831); Granger, July 30 (3881). Bulbilis dactyloides Raf. (Buffalo grass). — Low and matted, ordinarily only a few inches high; staminate and pistillate heads on separate culms. Not nearly so common as is generally supposed, for much of what passes for this is generally one of the species of Grama grass. They are, however, readily enough distinguished, es- pecially when they are headed out. On the open range these are all grazed down so closely that it be- comes difficult to recog- nize them. This grass occurs on the open plains, but especially in flat draws among the ridges of hills that intersect the plains at intervals. It has no sig- FiR. 11.— Slender Cord-grass (Spartina gracilis): a, spikelet; b, floret. nificance except as a pas- ture grass, and there seems to be some foundation for the belief that it is gradu- ally disappearing from the range. Pine Bluff's, July 6 (3616). Eatonia obtusata Gray (Early Bunch-grass).— Soft, handsome, and well leafed, 18 inches to 3 feet high, with slender, close panicled heads. In moist ground, either open or partly shaded, it makes a most luxuriant growth. Certainly a good pasture grass, and in some meadows it is a valuable part of the hay crop. (Granger, July 30 (3886); Grand Encampment Creek, August 13 (3993). Koeleria cristata Pers. (Phairir J une-(;i{ass).— Somewhat tiilted, verv leafy at the base; stems strict and erect, bearing a close cylindrical head, very variable in size, 40 from a few inches to a foot or two in height. Perhaps the most generally dis- tributed of our valuable pasture grasses, as it occurs in greater or less abun- dance on both plains and foothills, as svell as to some extent in the mountains. It is quite variable, also, in appearaiice, depending no doubt largely ui)on the stage of development that it has reached and to some extent npon its habitat.

Melica bulbosa (ieycr (BiMsors Melic-gkass, fig. 13).— A tall, handsome, grass, bearing small bulbs at the base of the straight stems; heads slender, but the spikeh'ts plump ; 2 to 3 feet high. An excellent grass, but usually of very scat- tering growth ; often protected from stock by growing among the undcrshrubs on Ihe banks of ravines. Not very widely distributed, in fact, observed only a few times in the foothills, (ireeu Top, June 29 (3265); Slieep Mountain, July 3 (3306) ; Battle Lake, August 16 (4023).

Poa fendleriana Vasey (Fendler's Spear-grass). — A small bimch-grass, 10 to 15 incbes high, with numerous leaves and ample panicles. It occurs on rocky slopes in tbe foothills in the western part of the State; seemingly neither frequent nor abundant, but undoubtedly an excellent pasture grass. Evanstou, May 29 (2970, 2986, and 2998). Poa flava L. (False Redtop). — Tall and slender, 2 to 3 feet high, with long, spreading panicles. In some localities a conspicuous grass in the wet draws on bottom lauds at least, so in inclosures where it is allowed to head out. In open ground and in pastures, stock graze it down closely, indicating that it is among 42 tlio most relished of pasture grasses; of consiclerablo importance in localities near Kvaiiston and Medicine liow Iviver. Evauston, Inly 27 (3848 and 3858); Medicine Bow River, Angnst 21 (4093). Poa glauca \ alil. (Speak c.hass). — Tliissiiiooth, handsome bunch-grass occurs spar- iuuly in the mountains. It prefers moist places, where, under favorable con- ditions, it will attaiu a height of 12 to 18 inches. It is an excellent pasture grass, as evidenced l)y the extent to which it is sought out by stock. Head of Pole Creek, June ill (3196). Poa laevigata 8cribn. (Smooth IjUNCII-cuass). — A bunch-grass of mnch value, 1 to 2 feet high. It has adapted itself to very diverse conditions, as shown by its being found iii all kinds of soil — on the strongly alkaline of the r.itter Creek Hats to that of the o])en mountain parks; on moist creek banks and dry hill- sides and ridges. It develops early, hence is of mnch value as early summer jjasture. North Vermilion Creek, .July 19 (3766); Colorado-Wyoming line, July 22 (3807) ; Evanstcm, .Inly 27(3837); Granger, July 30 (3891). Poa leptoconia Trin. — A rare grass of scatteiing growth, the stems weak and the lea\es soft and broad; observed but once as scattering, individual speci- mens on th(! broken banks of a streamlet in a subalpiuo ]>ark. Battle Lake, Angu.st 16 (1019). Poa longepedunculata Scribn. (LONG-.STALKKI) BUNCH (iU.VSS). — A remarkably line bunch- grass, the tufts large and close, 20 to 30 inches high ; leaves short and largely basal, the numerous naked stems slender and erect; ])aniclo amjile but close. It is a grass of the hill regions, occupy- ing the slopes and summits, often in considerable abundance. Sheep Mountain, July 3 (.3292). Poa lucida Vasey (Siiixixc Brxcn-OUAss). — .V wile, loose and spreailing; an excellent grass, attaining a height of 2 feet or more.

Probably a form of higher altitudes. Head of Pole Creek, July 22, (3435). Poa nevadensis Vasey (Nevada Blue-grass, fig. 15). — Forming small bunches, the ample leaves, numerous stems, and well-developed heads make this a grass that always attracts attention. In the open range it is always browsed down except where protected by fallen timber or otherwise. It seems to ])refer open woods on the slopes of the foothills or, more rarely, the partly shaded stream banks. Laramie Hills, June 16 ^3179^; "G." Summer ranch, July 23 (3823) ; Granger, July 30, (3891a). Poa pratensis L. (Kentucky Blue- grass, tig. 16). — This well- known grass needs no descrip- tion. It is widely distributed and everywhere recognized as a most important grass.

Poa reflexa Vasey & Scribn. (MouxTAix Blue-grass). — A beautiful form of the higher mountains, usually as a bunch grass but often more scattering; stems moderately slender, 10 to 18 inches high; panicle loose and ample, the pedicels retlexed in age. It occurs in ravines and sometimes in abundance on the slopes in subalpine stations. That it is an excellent pasture grass hardly admits of doubt, but it is too often in most inac- cessible places. Battle Lake Mountain, August 17 (4038 and 4044). Poa sheldoni Vasey (Sheldon's Blue-grass, PI. IV). — Stems slender and erect with well- formed heads; leaves mostly basal, short, slender, and some- what rigid; usually occurring as a bunch grass, varying in height from 1 to 2 feet, according to location probably belongs to the arid region, but is not contined to th(^ drier situations. In fact, it occurs more frequently on the drier portions of the bottom lands and on the higher ground about spring bogs. In all such situations it must be con- sidered as one of the valuable grasses. Its earliness detracts from its value as a meadow grass unless it can be grown by itself, as it is out of condition before the other constituents of the meadow are in condition for harvesting. Pine Bluffs, July 7 (.3644); Beaver Basin, July 22 (3806); North Fork, Vermilion Creek, July 18 (3754 and 3785); Evanston, July 28 (3869).

This buuch grass is valuable as jiasture, but, like the i)rt'ceding, would be more so if it oftener descended into the lov\-er altitudes of the foot hills or the plains. Cen- tennial Valley, .July 2 (3290) ; Battle Lake, August 17 (4049). Graphephorum muticum Scribn. (?).— A handsome grass, with broad green leaves; rather large stems, 2 to 3 feet high; head a close, nearly cylindrical panicle, 3 to 6 inches long. Probably very rare; secured but once. Battle Lake, August 16 (4012 and 4013). Panicularia americana MacM. (Keed Meadow-grass; Tall Manna-grass). — Stems stout, 2 to 4 feet high ; leaves large and abundant ; the panicle ample, loose, and sjireading, 6 to 12 inches long. This very hand- some grass thrives on wet bot- tom lands and in the shallow sloughs that border our streams. Its forage value is much under- estimated, for not only can im- mense crops of it be produced, but the quality of the hay is far above the average ordinarily secured from wet lands. Evans- ton, .July 24 (3871) ; Woods Land- ing, August 7 (3907). Panicularia borealis Nash (North- ern Meadow-c;kass). — Stem weak, moderately leafy, 2 to several feet in length, some- times rooting at the nodes in the mud at the bottoms of the ponds in which it grows; pani- cle very long and open, soon naked through the early disin- tegration of its spikelets. Of no economic importance, for it occurs, so far as my observation goes, only as scattering speci- mens in deep, clear, fresh-water ponds. Johnson's ranch, August 8 (3936); Grand Encampment, August 13 (3986). Panicularia nervata Knntze (Nerved Manna-GRA.ss, fig. 18).— Soft, succulent leaves and stems, rather weak, 2 to 3 feet high ; usually as a scattering growth in partly shaded bottom lands, but sometimes in considerable abundance in wet open meadows. It is greedily eaten by stock, but as a hay grass it probably lacks weight and substunce. North Vermilion Creek, .Inly 19 (3769); Woods Creek, August 9 (39').")); Cooiter Hill, August 22 (1405). Panicularia nervata stricta Scril>n.— Similar to the preceding, but smaller. Of small economic ini|Mirtance, as it oceiirs only as scattering specimens in the bioKen s]aut. It is, however, a bog form and hence difficult to utilize. Centennial Valley, July 2 (3275); "G," Summer ranch, July 23 (3822) ; Grand Encampment Creek, August 13 (3996). Carex nebraskensis Dewey (Nebraska Skdge).— This swamp sedge is very vari- able in size, but often attains a height of 2 feet or more. The leaves are very abundant, relatively broad and often nearly as long as the stems, on which are borne two to four large cylindrical heads. Though the hay produced from it will not weigh very heavy in proportion to the bulk, yet it must be considered as a valuable product. In meadows that are flooded early in the season it constitutes a considerable part of the whole hay crop. Pine Blufls, July 7 (3654); Evanston, July 27 (38.30); Cooper Hill, August 22 (4409).

Battle Lake Mountain, Anirnst 17 (4042). Carex nova Bailey (The New Sedge).— Erect and slender, stemmed with short Hat leaves; 15 to 25 inches high; somewhat scattering, in the wet spruce woods ;ind along the creeks in the mountains. Probably of value as pasture. Battle Lake, August 16 (4007). Carex preslii Steud.

Carex pyreuaica Wahl.— A very suiall, tufted form, only a few inches high, strictly alpiue, observed only about the permanent snowdrifts on the mountains. Baltic Lake Mountain, August 17 (4058). Carex raynoldsii Dewey (Raynolds' Sedge).— Erect but weak stemmed, leaves broad and Ihit; the short cylindrical heads usually two, a foot or more high; rare and very scattering. Battle Lake, August 16 (4020). Carex scirpoidea Michx. (Rush-like Sedge).— Erect with an abundance of short root leaves, only 6 to 10 iuches high. It develops early on wet ground on bottom lauds and so furnishes a perceptible part of the spring pasture. Pine Blufls, May 15 (2901); Laramie, May 31 (2943), Carex siccata Dewey (Hillside Sedge).— From strong, tufted root-stocks, slender stems and numerous leaves as long as the stems. This is a dry-ground sedge, being abundant on fertile hillsides, where it develops early and gives much valuable pasture. Evanston, May 29 (3001); also frequently collected in the Laramie Hills. Carex stenophylla Wahl. (Dwarf Sedge).— This is the earliest on the Laramie plains, but in many places it also maintains itself till late in the season. It often forms a fairly uniform growth, but its small size (4 to 6 inches in htight) and slenderuess make it seem rather insignificant. As spring pasture on the plains, it has value.

(Soft-leafed Sedge).— A very delicate, slender-stemmed and soft-leafed plant, a foot or less high, usually in damp, shaded places; never observed in sufficient abundance to have any economic signiticance. Woods Creek, August 9 (.3941). Carex tolmiei Boott.— A stout, mountain form with long, broad leaves, a foot or so high, usually as strongly root-tufted bunches. Not abundant enough to have much signiticance but evidently relished by grazing animals. Battle Lake, August 16 (4005 and 4072). Carex trichocarpa aristata Bailey (Awned Sedge),— One of the largest of the sedges, stems thick and producing a succession of heads, the leaves broad, flat, and often overtopping the stems, the whole producing a very dense growth 3 to 4 feet high. It prefers very wet ground, but produces abntidantly on ground that dries out in late summer. I have seen considerable areas yielding an immense amount of forage harvested with the usual niadiinery. Laramie, Sep- tember 15 (4469). Carex trichocarpa imberbis Gray (?).— This is much smaller than the pre«ediug with longer, denser heads; somewhat tufted and usually growing in the margins of creeks or ponds; not plentiful. North Vermilion Creek, .July 20 (3S02). Carex utriculata minor Boott. (Small Bottle Sedge).- A rank-growing sedge of the wettest ground, with thick stems and Jong, broad leaves, often 2 or 3 feet in lieight; heads usually three to four on each culm. It is very abundant and wididy distriinited; on grounds that become sufficiently dry to admit of it, it is cut and is said to Ibrm fair hay. Head of North Vermilion Creek, July 20 (3801); Evanston, July 28 (3861); Johnson's Ranch, Big Laramie, Augusts (3><96) ; Battle Lake, August 16 (4036), 53 Carex vallicola Dewey. — Soft-leaved aiid slender stemmed, less tlian a foot high; oil (he hiilsides, uot abimdunt. Hvanstoii, May 29 (3000). Carex variabilis Bailey (?). — A slender, erect form usually found in the margins of streams, 12 to 20 inches. Pine Bluffs, May 15 (2900). Carex variabilis elatior Bailey. — A bunch sedge of the most pronouuced sort, so tufted that it can scarcely he broken up, leaves abundant and stems fruiting freely, 20 to 30 inches higli. Probably of small economic value. Woods Creek, August 9 (3937) ; Glrand Encampmeut, August 13 (3985). Carex eleocharis I>ailey (?). — Filiform stems and leaves from tiiberous root-stocks, only 5 to 8 inches high. It makes a very close growth and has the aspect of an Eleocharis. In the locality where it was secured it was exceedinaly abundant in the drier parts of the meadows, even to forming continuous sods. Big Creek, August 11 (3972). Carex sp. — A small, leafy species, 6 to 8 inches high, somewhat tufted and forming a considerable growth on saline ground bordering some lakes. Little Laramie Kiver, July 24 (3445). OTHER FORAGE PLANTS. Besides the grass-like plants given in the preceding list there are many in the region designated the summer range, that furnish much browsing during the summer months, but these need not be mentioned in detail here. It is sufficient to call attention to the following as among the more important: First in importance are Legriminosce, which throughout the entire range are abundaiitly represented. Species of Astragalus abound everywhere and many of tlieni are freely eaten. In view of the fact that some {Astragalus nioUissimus, etc.) have reputed poisonous proper- ties, it is a question yet to be solved how generally they may be accepted as forage plants. Species of Thermopsis, abundant in some localities, are not without suspicion of having injurious properties. Among the legumes that pass unchallenged may be named the clovers {Trifolium longipes ^STutt., and other species) and Hedysarum (//. ameri- canum liritt. and H. mackcnzii Kich.), all of which are of frequent occur- rence and in some localities abundant. These are greatly relislied by stock and furnish an important part of the pasture. In the eastern i>art of the State another genus that is particularly well represented is Psoralea, the following species being abundant: P. laneeolata Pursh, P. UnearifoUa T. & G., and P. temiiftora Pnrsh. Of the valne of these species the writer can not speak for he does uot even know that stock feed upon them. Attention may be called to the following list, the plants of which are abundant in the summer range as well as in the desert. (For more or less conq)lete notes ui)on their economic value see the JJed Desert list (l). li4) in which they have been individually considered.) Astragalus. Chenopodium. Liipinus. Sarcobatns. Vicia, Sueda. Atriplex. Eriogonum. Eurotia lanata. Artemisia. 54 FLORA OF THE RED DESERT. The Red Desert is a fairly distinct area, an area with a flora peculiar to and characteristic of an arid, saline region. Its plants are there- fore listed separately, and all vascular forms that were secured are included, whether they are forage plants or not. This is done to indi- cate as fully as possible the real character of the vegetation and thus, by inference, the economic possibilities of the region. The following list of plants is based upon specimens secured during the summer of 181)7 along the line of the Union Pacific Railroad, from Pine Bluft's, on the eastern border, to Evanston, on the western border of the Desert. There are represented, besides the districts contiguous to the road, localities both north and south, some of which are from 40 to 70 miles distant from it. As the following are but the collections of one season, they must fall far short of constituting the complete flora of the region. CONIFERiE. Juniperiis knightii A. Nels. (Desert Juniper). — UsTially a shrub-like tree, much branched from the base, but occasionally more arboreous. Common in the sand- stone bluffs along fitter Creek and its tributaries. (See p. 7.) Point of Rocks, June 1 (3096); Eock Springs, .luly 26. SCHEUCHZERIACEiE. Triglochin maritima L. (Seaside Arrow-grass). — A low, tender, herbaceous plant, 6 to 10 inches high, abundant on wet alkali flats; possibly eaten by stock to some extent. South Butte, July 13 (3748). GRAMINEiE. Stipa comata Trin. &■ Kupr. (Needle-grass). — A loosely spreading bunch grass, easily known by the long, twisted awns that tbe fruits bear. A grass of some forage value and readily eaten by stock in the autumn and winter after the long, vicious beards have fallen. Bitter Creek, July 12 (3700). Stipa lettermani Vasey (Lkttkkmax's Nekdlk-(;rass). — A slender form with short awns, growing as a bunch grass among the sage-brush on the dry summits of the hills. Probably in itself valuable, but only occurs in small quantity. South Butte, July 13 (3738). Stipa nelsoni Scribn. (Nki-son's Needle-grass). — A tall grass, with very long beads and awns of medium length, foniiing small and ratlu^r loose bunches, with a fair amount of leaves; usually fouml in ()])eii-timbcrt'd areas, but also among the sagebrush on the sl(>])es below the pennaiient winter snowbanks; not })len- tiful. Fiftecn-iMilc Si)rings, July 13 (3731). Eriocoma cuspidata Nutt. (Indian Millet, see fig. 2). — A widely distributed bunch grass, from a few inches to a foot or more in height, easily known by its peculiarly branched pauich^s and tbe large, softly silky seeds. It is a glass of much value. Point of Rocks, June 1 (3094); Red Desert, June 3 (3122); Wam- sutter, July 10 (3680); Creston, August 28 (4416). Sporobolus airoides Torr. (Fine-top Salt-grass, see fig. 6). — This grass forms patches of various sizes on the huumiocks and drier ridges of bottom lands. The sod seems stitf and the stems, while somewhat slender, are also rather rigid. It forms, however, in some localities much valuable pasture. Black Rock Springs, July 13 (3723); Creeu River, September I (4457). 55 Sporobolus depaiiperatiis Scribn. (Dropseed). — A small hut valuable grass, form- lug a close, eveu sod of numerous slender leaves and stems; valuable as pasture, but of rare occuri^euce in the desert. South Butte, July 13 (3745) ; Creston, August 29 (4425). Calamagrosti-s hyperborea americaiia Kearn. (Sand-grass; Yellow Top). — A tall, slender grass, usually forming an even growth, on wet ground in either open or shaded places. Kara in the desert, occurring only about spring bogs. Black Rock Springs, July 13 (3717). Calamagrostis neglecta Gaertn. (Pony- grass). — An erect grass usually found in the margins of ponds and ditches, forming an even growth and bearing an abundance of slender leaves ; a fine appearing and valuable grass. South Butte, July 13 (3750). Deschampsia caespitosa Beau v. (Tufted Hair-grass). — A bunch grass with slender stems and numer- ous leaves, common throughout the State, sometimes in comparatively dry ground, but usually along streams and about spring bogs. It furnishes much pasture, but after it matures and dries on the ground it does not seem to be relished by stock. Black Rock Springs, .Inly 13 (3718); Fifteen-mile Springs, July 14 (3727). Koeleria cristata Pers. (Prairie June- grass).— A straight, slender grass with cylindrical heads, forming small tufts, 8 to 12 inches high. Common on the plains and in the hills, and form- ing an important part of the early pasture ; far from common in the Red Desert. Creston, August 28 (4417). Catabrosa aquatica Beauv. (Water WHORL-(iRASS, fig. 22). — A soft, watery grass, usually with stems partly prostrate and rooting in the soft mud of the sluggish streams and spring-led bogs, where it abounds. Horses and cattle eat it readily and will wade knee-deep in the mud to secure it. South Butte, July 13 (3734). Distichlis spicata Greene. (Salt-grass; Alkali-grass). — A stiff, pale, harsh grass, occurring on alkali flats, even where the ground is white with salt. Though far from the best, it is eaten down by stock where other forage is scarce. Black Rock Springs, July 13 (3722). Poa buckleyana Nash. (Bunch-grass). — A slender-stemmed, narrow-leafed bunch- grass of much value in this State, but of small significance in the Desert proper. On some of the luoister slopes and draws it becomes of some importance. Green River, June 1 (3067) ; Bitter Creek, June 2 (3100) ; Creston, August 28 (4418). Poa juncifolia Scribn. (Alkali Blue-grass, PI. V).— A small, erect bunch-grass with slender, pointed leaves. This new species belongs to the arid region, but it is not confined to the desert exclusively. Usually of scattering growth, it sometimes forms almost a continuous sod. Reported as one of the desirable Fig. 22. — "Water Whorl-grass {Catabi-osa aquat- ica) : a, 6, apikelets ; c, d, florets. 56 pasture grasses, and would probably be of value as a meadow grass, especially where the soil and the irrigatiou waters are not of the best. Black liock Bntte, July 13 (3721). Poa laevigata Scribn. (Smooth Bunch-grass). — ^This species is found throughout the southern ]tart of the State, in the desert as well as in the hills and moun- tains, sometimes in comparatively dry places, l)ut preferring moist banks and wet Hats. It forms a valuable part of the early summer forage. Red Desert, June 3 (3118); Pole Creek, June 19 (3197); Wamsutter, July 10 (3668): Bitter Creek, July 12 (3708); Point of Rocks, July li (3751). Poa lucida Vasey (Shixixg Buxch-grass. )— A grass of more than usual importance. It grows to a height of 1 or 2 feet, producing numerous stems and broad leaves of excellent quality. It constitutes an api>reciable part of the forage in the desert as well as in the summer range. It is found on the dry plains, but is more abundant and luxuriant in the vicinity of spring bogs and creeks. Point of Rocks, June 1 (3093) ; Bitter Creek, July 12 (3707) ; South Butte, July 13 (3733). Poa sheldoni Vasey (Sheldon's Blue-grass).— Bitter Creek, July 12 (3696). Puccinellia airoides Wats. & Coult. (Alkali Meadow-grass).— This slender, erect o-rass is seldom seen except in the margins of ponds and ditches, and seems to prefer water with a considerable percentage of alkali. Whether it could be introduced to advantage on wet alkali groun to 9 inches high; on the drier ridgea about the spring bogs; not abundant. Black Rock Springs, .July 13 (3720). Carex multinoda liailey. — This slender-stemmed sedge produces a large amount of long, tender leaves, and forms a close sod. It is one of the most valuable from a forage standpoint of the sedges of the desert. South Butte, .July 13 (373.^). Carex uebraskensis Dewey (Nkbkaska Sei>ge). — Very leafy, the leaves broad, almost as long as the stems. 1 to 2 feet or more in height. Usually in very wet ground, such as ditches and meadow bogs. When these dry out in late summer it is cut to a considerable extent for hay. It of course occurs in the desert only rarely, but in some of the bogs it is quite almndant. South Butte, July 13 (3741). Carex stenophylla Wahl. — A small, scattering form only a few inches high, usually developiug early; among the sagebrusii in the desert it is too scattering to have .any signiticance. Creston, August 2S (4415). Carex teretiuscula Good. — This form has very slender, almost cylindrical leaves and stems but makes a very (-lose and even growth on wet saliue soil, often in pjitches of considerable size. Black Rock Springs, July 13 (3710 and 3725); South Butte, July 13 (3734a). JUNCACEiE. Juncus balticus Willd. (Baltic Rush). — A well-known rush with rather rigid stems which arise (juite regularly from a creeping, underground root-stock. It varies greatly in both size and habitat. In wet ground, as in the juargins of a stream, it may attain a height of 3 feet or more; on dry sandy slopes, where it was sometimes found to occur in the desert, it may be scarcely a foot high. It proba- bly has little forage value, though it is eaten to some extent with the other vegetation when intermingled with it. I'oiut of Rocks, June 1 (3095); Bitter Creek, July 12 (3690). Juncus confusus Coville. — A slender form of compact growth, 10 to 15 inches high. In some of the deeper draws in the desert where the spring snows lie late this forms extensive patches of close sod. Whether it is eaten to any extent by stock of any kind the writer is unable to say. Creston, August 29 (1427). Juncus xiphioides moiitanus Kngelm. — Tall and slender with aiujile U.it leaves, 20 to 30 inches high. It is abundant in many of the spring bogs, aud seems to be freely browsed by stock. South Butte, July 13 (3739). LILIACE^J. Allium mutabile Michx. (Wili> Oniox). — Peculiar among the wild onions in that it sometimes produces little bulbs in the inflorescence. All of the specimens colle(;ted bore bulblets. Not common. In a draw among the hills north of Uotk Si)rings. The (iaj), .July 25 (3600). Allium reticulatum Don. (Fkaskr's Wild Onion). — A common (brni on the slopes of the hills throughout the ilesert. Green River, May 31 (3033;; Point of Rocks, June 1 (3076). SALICACEiE. Salix cordata mackenzieana Hook. — This willow becomes a small, rather shapely tu-c. It seems to be a very common form on the banks of Green River and some of its tributary creeks. Green River, May 31 (30()6). 59 Salix fluviatilis Xutt. (River-baxk Willow). — This little alentler-stpmmed and slender-lcafeil form so conimon on all creek and river banks seems to he equally common on tb(; banks of Bitter Creek and its tributaries. It forms a green fringe or even large patches on the low, salt-encrusted banks. Not usually thought to have any value, but here in the desert occasionally browsed by sheep, especially wben snow makes other feed hard to obtain. Bitter Creek, .June 2 (3102). Salix bsbbiana Sargent. (Bebb's Willow). — It was something of a surprise to find tMs willow in the heart of the desert. In a draw near the railroad at Creston, August 27 (4270). POLYGONACEiE. Eriogomim campanulatum Nutt. (Narrow-leafed Eriogonum). — Often browsed by cattle, but of no considerable value. The Gap, north of Rock Springs, July 25 (.3.597). Eriogonum effusum Xutt. — A small, branched plant with a woody base, the young stems tender and eaten by sheep; not plentiful. In the clay draws at the head of Salt- Wells Creek, .July 17 (37.53). Eriogonum ovalifolium Nutt. — A small ca^spitose plant, exceedingly common on Ixith plains and hilis. There are several forms of it, the commoner one having white flowers, but in the desert, wbere it is especially abundant, bright yellow forms predominate. It is probably of no economic importance". Point of Rocks, June 1 (3087) ; Bitter Creek, June 2 (3099) ; Red Desert, June 3 (3117). Rumex tuberosum A. Nels. (TtiBEROXs Dock). — On some of the alkali-covered flats adjacent to Bitter Creek this unusual plant was found. A dock springing from large oblong tubers which lie shallowly buried in the loose, ash-like alkali soil. From these the plants spring up early, the stems, a foot or more in height, bearing long spikes of flowers; the large, bright-red wings of the fruits make them very conspicuous on the otherwise almost naked ground. Bitter Creek, June 2 (3114). CHENOPODIACEiE. Chenopodium album L. (Lamb's Quarters). — This well-known weed seems to be at home even in the desert, except in the more pronounce feet high; very rare within the borilers of tlic desert; only below the permanent Avinter snowdrifts. South Butte, July 13 (3536). Potentilla glandulosa Lindl. (Glandclar Cinquefoil). — A handsome perennial plant, some 18 to 30 iu(;hes high, sparingly branched; flowers yellow. Only on moist slopes below snow banks. South Butte, .July 13 (3534). Potentilla anserina L. (Silver-weed). — A tufted, spreading plant, common on wet, saline soil everywhere in the desert as well as elsewheie iu the State. Gaum macrophyllum Willd. (Lar(;i:-leai"ED Avens). — A ptjrennial herb, a foot or two in height, sometimes l)ranched above, with large, lobed root-leaves ou long ])etioles. Infrequent; on the moist slopes below the winter snow lianks. South Butte, .luly 13 (3.543). Cercocarpus parvifolius H. & A. (Mountain Mahoc.anv). — A stiff, scraggy shrub, 3 to 6 feet liigh; common on rocky slo])e.s throne iiout the southern part of the State. Observed in several i)lace8 in the desert ou the vviuter snow slopes. 63 DRUPACEiE. Prunus demissa Walp. (Western Wild Cherry).— A shrub or small tree, vary- ing greatly iu size in different situations. In the desert it occurs only below the brow of some of the steeper hills, where the winter snows become piled and remain late in the season. Observed in a few localities and collected at The Gap, south of Kock Springs, July 25 (3599). PAPILIONACEiE. Lupinus argenteus Pursh. (Silvery lupine).— A perennial, bushy, branched plant, 1 to 2 feet high, bearing long, dense spilces of purple flowers ; pods, silvery, silky, and containing only a lew large seeds. In some of the grassy draws among the hills. Creston, August 29 (4428) The lupines set'iii to thrive in the desert, and if it could be shown that they have any economic value they could undoubt- edly be cultivated. Lupinus leucophyllus Dougl.— Somewhat similar to the i>receding, but occupying drier situations. The driest bluffs and ridges do not seem to be unsuited to it. It is by far the commonest lupine in the desert, and great crops of it were observed even on the suniuiits of the white Green River bluffs. Green River, May 30 (3023) ; Bitter Creek, June 3 (3109) ; Fifteen-Mile Spring, July 13 (3729). Astragalus grayii Parry (Gray's Milk-vetch).— A small, erect form, 8 to 12 inches, with yellowish-white flowers iu a rather short raceme. Scattering and rare. Bitter Creek, June 3 (3115) and July 12 (3.530). Astragalus haydenianus uevadeusis Jones.— This form was collected and noted in several places. Of unknown forage value. Bitter Creek, June 3 and July 12 (3116 and 3711). Astragalus hypoglottis L. (Purple Milk-vetch).— A low, spreading plant, only a few inches high, but often forming compact beds. It has the appearance of making excellent pasture, and looks as if it might be a good substitute for clover. Stock graze it down in some localities, and it is said that as an ingre- dient of hay, sheep pick this out flrst. It thrives on saline soil even where there is an excess of alkali, as for example on the low banks of Bitter Creek. There is no reason to think that it would be more difficult to secure a crop of this than of many other plants that are used for forage. The question that remains to be settled is. Are the plants of this genus nutritious and safe? Some of the species have reputed poisonous qualities; for example, A. mollinsimnH, one of the "locos.'' It is yet to be determined which are the valuable and safe species. Bitter Creek, July 12 (3688). Astragalus megacarpus Gray (Large Bladder-pod Vetch).— A spreading succu- lent plant with large, thin, inflated pods and small seeds. This also thrives iu saline soil, forming large, green mats on the alkaline flats of Bitter Creek ; June 3 (3113). Astragalus sp. — An erect, slender-stemmed and slender-leafed form, found in the sandy slopes of the Bitter Creek hills. Point of Rocks, June 1 (3081). Vicia dissitifolia Greem- (American Vetch),- A slender-stemmed, vine-like plant, climbing over other plants among Avhich it is growing; vines 2 to 3 feet in length; accounted most excellent forage. On several occasions stockmen have brought specimens saying "If you can tell us how to secure enough of this we will be satisfied; we want nothing better." It makes excellent hay; sheep especially do well upon it. It is widely distributed, but rarely forms anything like a full crop of forage. The possibilities under cultivation are yet to be determined. Bitter Creek, July 12 (3703). Vicia linearis Greene (Narkow-leafed American Vetch).— Very similar to the preceding, but smaller iu every way, with very narrow leaves. Equally valu- able as forage, but not abundant. Bitter Creek, June 2 (3104). 64 LINACEiE. Linum le^visii Pursh. (Lewis's Wild Flax), — A plant with slender leaves and wand-like stems arising from a woody, perennial root, 1 to 2 feet high; common in the Wtate, but rare in the desert. Red Desert, June 3 (3119). ANACARDIACEiE. Rhus trilobata Nutt. (Stinking Sumach). — A small, glabrous, branching shrub; leaves, three-lobed; very common on dry ridges and canyon sides. Green River, May 31 (3065). MALVACEiE. Malvastrum coccineum Gray (Red False Mallow). — A much-branched perennial herb, with silvery leaves and large, red flowers. Plant not more than a few inches high. Green River, May 31 (3057). LOASACEiE. Meutzelia sp. ( ?). — A small form not yet determined; possibly new. CACTACEiE. Echinocactus simpsoni minor Engelm. — A small, globular cactus; infrequent. South Butte, July 13 (3.-)53). Opuntia polyacantha Haw. (Many-spined Opuntia). — Composed of many flat, obovate joints, flercely spiny. Very abundant. Wamsutter, .July 11 (3523). Opuntia polyacantha platycarpa Coulter. — In general appearance very similar to the preceding. Both are here often called Prickly Pear cactus. Bitter Creek, July 12 (3528). ONAGRACEiE. Epilobium sp. (?). — Two species in this genus were collected, but they do not seem to agree exactly with any of the descriptions at hand, so they are left unnamed. Nos. 3512 and 4272, from South Butte and Creston, respectively. Taraxia breviflora Nutt. — A small, steuilcss plant, with a cluster of root-leaves out of which the flowers hardly rise. Creston, August 29 (4273). Auogra albicaulis Brittou (Praikie Evening Primrose). — An herbaceous plant, with rather slender white stems, almost simple or branched from the base, G to 15 inches high; large wliite flowers, becoming pink as they grow older. Green River, May 31 (3064); Point of Rocks, June 1 (3075). Chylisma scapoidea Small. — An herbaceous branching plant, with dark green leaves, an6). Cymopterussp. ( ? ). — \ species of this genus that is as yet undcterniined was sciureil at I'oint of Rocks, June 1 (30H3). GENTIANACEiE. Gentiana afllnis CJriseb. (Oiu.oN(;-leaki;i) (Jkntian). — A perennial with leafy cliis- tired stems, 6 to 12 iucbes high. Common on low, wet ground. I'oiiit of Rocks, August 30 (4275). 65 POLEMONIACEiE.

Differing from the other Rabbit-brushes of the region in that it does not form close clumjjs. but grows as single, conspicuous shrubs, branched above, thus simulating in habit a miniature tree. C'reston, August 2S (4419). Chrysothamniis stenophyllus fireene. — A small shrnb, the older branches s])read- ing, the younger sonunvhat fascicled and erect, white.

This grass is (Hiite distinct from the Fig. 1— Couch-grass (Agropyron repent) . "Blue-stem" grasses of Nebraska, which are Bpeciesof Jn(ho2)ogoii (A. 2)rovincialis). There are a num- ber of other species of Agropyron or wheat-grasses in the Rocky Mountains, some of which are evidently excel- lent hay grasses and well deserve the attention of the agriculturist. No. 6. Agropyron tenerum Vascy. Slender Wheat-grass. A perennial buncli grass growing in the northern prairie region from Nebraska to Montana and Manitoba. Seed of this grass is now on the market, its sterling quali- ties for hay having long been recognized by North- western fainiers. It produces an abundance of soft, leafy stems and root leaves, and ripens a large amount of seed that is easily gathered — two of the chief re(|ui- sites of a good hay grass. This grass is well adapted for cultivation, and the area devoted to it is deservedly increasing each year. Fio. 2. -Redtop alba) . {Af^rostis No. 7. Agrostis alba Liiin. liedto]» or Herd's-grass. Und(!r the botanical name of Agroslia alha are included a number of varieties, some of which have received distinct Latin names; :i8, for example, Agroaiia vulgaris and Agrostifi stoUnifera, and many Englisli or local names; that most generally applied in the Middle and Eastern States heing llerd's-grass, and in the South and West, Redtop. The great variability of this grass has led to much diversity of opinion in regard to its value. The taller forms are largely cultivated for hay, being usually mixed with timothy and clover. This grass requires con- siderable moisture in the soil, and is one of the best for permanent pastures in the New England and Middle States. It makes a very resistant and leafy turf, which Avell withstands the trampling of stock. It grows well, also, as far south as Tennessee. Among the forms of low growtli are two varieties which are unsurpassed, either in fineness or richness of color, for making lawns. No. 8. Agrostis asperifolia Trin. Rough-leafed Bent. This grass is common in the Rocky Mountain regions and on the Pacific Slope, grow- ing chiefly in the mountain parks and along water courses. Its slender leafy culms are 2 to 3 feet high, and the narrow, pale-green, and densely flowered panicles 4 to 6 inches long. .Judging from the appearance of this grass, it is likely to prove, under cultivation, superior to the Herd's-grass or Redtop of the East, at least for hay. No. 9. Agrostis canina Linn. Rhode Island Bent. This species of bent has been introduced into this country from Europe, and ia cultivated to some extent in the Eastern States. It resembles Herd's-grass (Red- top) somewhat, but has shorter and narrower leaves. It makes a close sod, and is considered valuable for permanent meadows and pastures. It is one of the best grasses for lawns, and for this purpose should be sown at the rate of 3 to 4 bushels per acre. Retail price of seed quoted in New York catalogues, $2.75 per bushel. No. 10. Agrostis coarctata (Reicbb.) Ehrh. Sea-coast Bent. A creeping perennial with sleuder culms, the upright branches 1 foot high, short and narrow flat leaves, and densely flowered panicles 2 to 4 inches long. It grows in damp soils and sands along the sea coast from Newfoundland to New Jersey, often occurring where constantly drenched by the flying salt spray. It is a fine- leafed, excellent turf-forming species, valuable for lawns. A similar if not identical species is common in western Oregon and Washington. No. 11. Agrostis exarata Trin. Northern Redtop. The grass upon which this species was founded is a native of Alaska, but a number of forms which occur in the Rocky Mountain regions and on the Pacific Slope have been referred to it. Some of these have been characterized as distinct species, and there are several among them which, from their tall, leafy habit and vigorous growth, indicate the possession of considerable agricultural value, although none of them have as yet been introduced into cultivation. They are deserving of the attention of the agriculturist, and their culture is recommended, particularly on the Pacific Slope. They would doubtless thrive in the Eastern and Middle States, and possibly supplant, by their greater luxuriance and better qualities, some of the species now cultivated. No. 12. Agrostis scabra Willd. Rough Bent. A slender, erect, tufted annual, with numerous very narrow basal leaves, and deli- cate, widely spreading capillary panicles, which at maturity break away from the culm, and are blown about by the wind, hence one of the common names, "fly-away-grass." Before the panicle has fully expanded, this grass is some- times gathered and sold under the name of "silk-grass " for dry bou(iuet8. It is widely distributed throughout the United States, but is of little or no agricul- tural value. In irrigated meadows of the Northwest this species, or a form of it, is occasionally sufficiently abundant to furnish a large amount of hay which is regarded of good quality. 10 No. 13. Agrostis stolonifera Linn. Creepiuj? Bent. By some regarded as only a variety of Agrostis alba, with long, prostrate or creeping stems, well adapted for sandy pastures near the coast, and useful, perhaps, for binding shifting sands or river banks subject to wash or overflow. It makes a good pasture grass for low lands, especially for those which are somewhat sandy, and produces a fine and enduring turf for lawns, for which is is especially well adapted. It is not a productive hay grass, although it has a record of yielding on rich, peaty soil 7,742 pounds of hay and 2,722 pounds of green aftermath per acre. If sown alone, sow at the rate of 2 bushels per acre, or for lawns 3 bush- els. Current retail price in New York, $3.50 per bushel. No. 14. Agrostis vulgaris With. Herd's-grass ; Redtop. This is little more than a variety of Agrostis alba, already noted. It is quoted in the seed catalogues as a distiuct species, and is recommended for mixtures designed for permanent pastures or meadows. It suc- ceeds as far south as Tennessee, and is often sown with timothy and red clover. Retail price of seed, New York market, $1 to $1.50 per bushel. No. 15. AlopecurusgeuiculatusLinn. Water Foxtail. (Fig. 3.) A low, usually procumbent grass, with slender stems 8 to 18 inches long, often rooting at the lower joints. It usually grows iu wet places, and is A-ery widely distributed throughout the north temperate zone. It has cylindrical heads or panicles, resem- bling those of Meadow Foxtail, but much smaller. This grass enters into the natural herbage of low. wet meadows and pas- tures, and in such places affords excellent grazing, being tender and nutritious. Alopecurus fnlrua is simply a variety of this, with short-awned flowering glumes. Under favorable cireumstauces this grass makes a good turf and a pleasing lawn of a deep rich green color, remaining green throughout the severe winter weather of the Middle States. No. 16. Alopecurus occidentalis .Scribu. Mountain Foxtail. A grass of the mountain mejidows of the Rocky Mountains, growing in rich soil along streams and in the open parks. It has sleuder, erect stems 2 to 3 feet high, with short, oblong heads, thicker and shorter than those of common Meadow Foxtail. This grass is occasionally found covering extensive areas to the exclusion of other 8i)ecies. It yiehls a large bulk of tine, long, bright- colored hay, which is highly valued where it can bo obtained. For the more elevated meadows of the Rocky Mountain region, and doubtless also for the New r.ngland and Xortli Middle States, this grass would form an excellent addition to the cultivated species, and its introduction is recommended. No. 17. Alopecurus pratensis Linn. Meadow Foxtail. (Fig. 4.) This well-known European grass has been introduced into this country and culti- vated to some extent in the New England and Middle States. It is a valuable grass for moist meadows and pastures, particularly the latter, on account of its Fig. 3.- -Water Foxtail (Alopecurus (jeniculatuH) . Bui. 14, Div. of Agrostology Plate I.

Department of Agriculture. 11 early growth, being one of the earliest of the cultivated grasses. It is very hardy, and on good soil yields a large amount of excellent forage. In Europe it is reoarded as one of the best perennial pasture grasses. It should enter into all nuxtures for permanent pastures, V>ecause it is very last- ing, highly nutritious, and earlier than most other species. This grass has a record of producing 20,418 pounds per acre of green grass, 6,125 pounds of hay, and 8,167 pounds of aftermath. It is never sown by itself, but is always mixed with other grasses and forage plants, because it gives a full yield only in the second or third year. Average number of seeds in a pound, 907,000. Price of seed quoted in New York catalogues, $2.30 per bushel, or $32 per 100 pounds. No. 18. Ammophila arenaria (Linn.) Link. Beach-grass, (Fig. 5.) This grass grows more or less abundantly along the sandy coasts of the Atlantic and the shores of the Great Lakes. It has strong, creeping rootstocks, upright stems 2 to 4 feet high, and long, rather rigid leaves. The narrow, densely flowered panicles which terminate the stems are from 3 to 10 inches long. It is one of the most valuable grasses adapted to bindinjj; the drifting sands of our coasts, and has been culti- FiG. 4. — Meadow Fox- tail {Alopecuruspra- vated for this purpose in this as well as in other countries. The action of this grass in hold- ins: the drifting sands is like that of brush or bushes cut and laid upf)u the ground in accu- mulating snow when drifted by the wind. The sand collects around the clumps of grass, and as it accu- mulates, the grass grows up and overtops it, and will so contiuTie to grow, no matter how high the sand hill may rise. This process goes on over the whole surface of the plantation, and thus many acres may be raised far above their original level. A plant will, by gradual growth upwards, finally form stems and roots sanded in to the depth of fully 100 feet. Beach-grass is best propagated by transplanting (PI. I, fig. 1). The grass is pulled by hand and planted 1 to 2 feet apart, according to the slope, by forcing a long spade or shovel into the sand, which is then carried forward, making an opening into which the roots are thrust, the spade then being withdrawn and the sand pressed close about them. The planting may be done either in the spring or fall, preferably in the fall. When propa- gation is by seed, the sowing should be done early in the spring and brush laid over the ground for holding the sand and seed temporarily in place. Beach- grass has been used for the manufacture of coarse paper, and it makes an excel- lent and very durable thatch. It is of no value for fodder. Fig. 5. — Beach-grrass (Arn^yio- phila arenaria): a, base of culm; 6, inflorescence: c.ligule. 12 No. 19. Andropogon contortus Linn. Twisted Beard-grass. A stout, leafy perennial, 1 to 3 feet liigb, aifording excellent grazing when young, but the mature seeds are much dreaded by sheep owners, as by their peculiar structure they not only become attached to and injure the wool, but often pene- trate the skin and even the intestines of these animals. The strong rhizomes and tough fibrous roots which this grass has, commend it as a soil binder for river banks, dams, etc. The awns indicate by their twisting the amount of moisture iu the air, and may be used as rain or fair weather indicators. In India this grass is used for thatching. It is a native of tropical and subtropical regions of both hemispheres, extending northward into western Tc^xas, Now Mixico, and Arizona. No. 20.

It grows in low grounds and marshes from southern New York to I'lorida, also occurring in Mexico and liower CaliCnrnia. This species is esteemed a valual)lc pasture gra.ss in the South. Its stems and leaves when young, are tender and .juicy and are relished by sto(;k of all kinds. Later the stems become tough and woody and are of less value. No. 21. Andropogon halepensis (L.)

The jtanicles are expanded during llowering and arc from (> to 12 inches long. It is a native of southern Europe and the warmer parts of Asia and northern Africa. It was introduced into this country about sixty years ago, ;ind h.iH now become widely distributed and well known throughout the Southern 13 states. In the warmer parts of the Southern States it makes rapid growth, la but little affected by drought, and the hay, if cut just as the grass is coming into bloom, is much liked by all kinds of stock. Two or three cuttings may be made during the season. The extensively creeping rootstocks are fleshy and tender, and hogs are very fond of them. These roots literally fill the ground near the surface, and every joint is capable of developing a new stem. This grass, when once it has become established, is exceedingly difficult to eradicate, and hence has come to be greatly feared by the majority of farmers. Unless one wishes to give up his laud entirely to Johnson-grass, and can certainly prevent its spreading to the lands of others, its introduction would be of doubtful econ- omy, owing to its powerful and rapidly spreading roots. In India the natives make rude writing pens from the stems. No. 22. Andropogon hallii Hack. Turkey-foot. This is a stout grass, from 3 to 6 feet high, closely related to the Big P.lue-stem {Andropogon 2)rovincialw), but appears to be confined to the sandy regions of the West. It is a good sand binder and is common in the sand hills of Nebraska, and extends southward into Texas. Its agricultiiral value is not known, but although more woody, it is probably nearly as valuable as Big Blue-stem. No. 23. Andropogon nutans Linn. Bushy Blue-stem. (Fig. 7.) This is a stout perennial, 4 to 6 feet high, growing in dry soil along the borders of fields and open woods, and on the prairies of the West it often forms a large proportion of the so-called prairie hay. It is held in little esteem in the Eastern and Southern States, but in the West it is said to make excel- lent hay, and is particularly valuable because of the rela- tively large amount of long root-leaves which it produces, is given the first place among Fig. 8. — Big Blue-stem (Andropogon provincialis) : a to g, details of the spikelet. All stock eat it greedily. In South Dakota it the native grasses as a hay-producing species, thriving best on the rich prairie bottoms. During the dry season it produces but little seed, though it usually makes a good growth of root leaves. In the middle Atlantic States this grass seeds freely and the seeds are easily collected. No. 24. Andropogon provincialis Lam. Big Blue-stem. (Fig. 8.) A stout perennial, with erect, more or less branching, and often bluish or glaucous stems, 2 to 6 feet high, long leaves, and flowers in short spikes, which stand two to five close together at the apex of the stem or its branches. These spikes are bluish or purple, sometimes pale green, and more or less hairy. This grass has 14 a wide range, extending over the United States east of the Kocky Mountains, and in the West and Northwest, particularly in the Missouri region, it is very abundant, and is highly valued for hay. It grows in a great variety of soils, and under extremely varying conditions of climate, and enters largely into the composition of the hay of the prairies. The early growth consists of a great adundance of long leaves, and if cut in early bloom the hay is readily eaten by horses and cattle, but if allowed to fully mature the stems become hard and woody and the hay produced is of inferior quality. Investigations of the seed production of this Andropoaon indicate that it matures seed rarely. It is stated that a very favorable season of moisture is required to make it fruit abun- dantly. This lack of fertility, if really true, will be a serious obstacle to the general propagation of the grass by the usual and convenient method of seeding. No. 25. Andropogon saccharoides Swz. Feather Sedge-grass. A variable grass, growing to the height of 1 to 3 feet, with nar- row, silvery-bearded panicles. Some forms of this species have been introduced into cultivation for ornament. It is a native of our Southwestern States and Territories, in some of its varieties extending southward to Chile, where it is re- garded as one of the best pasture grasses of the Cordilleras. No. 26. Andropogon scoparius Michx. Little Blue-stem. (Fig. 9.) A rather slender perennial, 1 to 3 feet high, more or less branched above; the slender racemes are single and terminate the culm or its branches. This grass has a similar range to the Big Blue-stem, extending over nearly all of the United States east of the Kocky Mountains, and in the prairie regions it is nearly always found associated more or less abundaiitly with the Big Blue-stem and Bushy Blue stem. It is common in the mountain districts of the South, and is valued there for grazing. In the West it is cut for hay, but is not so much thonubt of as the Big Blue-stem. In South Dakota this is one of the most common grasses in the basins of the Bad Lands. No. 27. Andropogon sorghum sativus Hack. Includes the cultivated varieties of sorghum. Andropogon sorghum includes many varieties, a number of which have been recognized by some iintbors as distinct botanical species under the genus Sornlunu; otheis, includ- ing Hackel, have referred them all to the genus Androimjnn. Hackel has elaborately worked out the botanical characters of the species and characterized tlie known varieties, giving to each a technical name. It is not necessary here to follow out his classification, which is apparently good. In the works of otliers there is much confusion in the botaui(;al classification, and still more in the applica- tion of the connnon or English names. The same name has been applied to ditferent varieties and the same variety has often been designated under vaiious names. All the forms are of Eastern origin, and have arisen probably from a common stock through ages of cniltivation. From varieties of this species are obtained grain, which furnishes nutritious food for man and domestic animals, particularly poultry. Sirup and sugar in commercial quantities are obtained from the saccharine varieties. The variety mcchavatus, or caiinese sugar-grass, yields about 13 per cent of sugar, lirooms and brushes, used in ill civilized countries, are made from the iuliorescence of the variety known as l)room corn, and all furnish fodder of more or less value for farm stock. Fio. 9.— Little Blue- stem (Androimgon tcoparhin). In Africa alcoholic 15 drinks are prepared from the grains, and useful coloring pigments are con- tained in the fruiting glumes. The variety known as Kalir corn (PI. I, tig. 2), which grows to the height of 4 or 6 feet, has been cultivated with great success as a fodder plant in the semiarid regions of the West. In fact, all the sorghums will grow in drier climates or under more trying conditions of drought than Indian corn. They may be cultivated in much the same Avay as that cereal, but the seed may he planted more thickly. In chicken corn or white Egyptian corn (var. cernnuvi) the deusely flowered panicle is abruptly bent or recurved, so that it points downward. This variety is largely cultivated in tropical and northern Africa and in some parts of southern Asia, where it is used as a cereal. It is occasionally grown in this coun- try, the seed being prized as food for poultry. The vari- eties adapted for the production of fodder or silage are particularly valuable for cultivation in the South and Southwest. The amount of fodder produced is often very large, of excellent quality, and there are few among the larger grasses better adapted for soiling. Yellow Mile Maize, AVhiteMilo Maize, and .Jerusalem Corn, non- saccharine varieties of Andropogon sorghum, are grown both for fodder and for the seed, particularly in the Southwestern States. No. 28. Andropogon squarrosus. Linn. fil. Vetivert. A stout perennial, 4 to 6 feet high, with strong, fibrous, and highly fragrant roots. A native of India, occurring also in some of the West India Islands and Brazil, growing in marshes and on river banks. Introduced into l.oui- siana many years ago, and now spontaneous in some of the lower parts of that State. Cultivated successfully at Knoxville, Tenn., where the fragrance of the rhizomes and roots was developed to a marked degree, btit the plants did not bloom. In India this grass is largely used for thatching, and is woven into mats, which serve as screens or shades for doors and windows (tatties), awn- ings, covers for palanquins, and fans, and brushes used by weavers in arranging the thread of the web are made from either the roots or the whole plant. The roots, laid among clothing, impart a pleasing fragrance to the gar- ments and are said to keep thorn free from insects. Fans made from the root fibers were among the articles on sale at the World's Fair in the Javanese bazaar. The roots are an article of commerce sold by druggists. In Euro- pean drugstores the roots are known as lUtdix miatheri or Radix vetiveriw, a stim- ulant or antiseptic. They yield a perfume known as vetivert, or, in India, itar. No. 29. Andropogon virginicus Linn. Broom-sedge. (Fig. 10.) A rigidly erect perennial, 2 to 4 feet high, bearing a narrow, elongated, and loosely- branched panicle of silky-bearded racemes. The stems are strongly flattened near the base, and at maturity they are too hard and woody to be eaten by stock or to be of any value for hay. When young, however, this grass affords most excellent grazing. Milch cows fed upon it are said to yield butter of superior quality. There is probably no native grass better known to the farmers of the South than this, aud although possessing some value, as here indicated, it is, broadly speaking, one of the worst weeds of that section, interfering seriously with the formation of permanent meadows. Constant tillage or very close graz- ing appears to be the only means of keeping this grass from occupying the land. Fig. 10. — Broom Sedge (Andrupoc/on virgini- cus). 16 No. 30. AntLoxanthum odoratum Linn. Sweet Vernal-grass. (Fig. 11.) A jierennial, early-flowering, sweet-scented grass, introduced into this country from Eurojie, and tiow widely distribut<>d over the Eastern and Central States. It is an inferior fodder grass, but owing to its earliuess it possesses some value in mixtures for pastures, and its sweet scent adds a pleasing fragrance to hay, of which it should form only a small percentage. The leaves have a bitter taste, and the grass is apparently unpalatable to stock, for they will not readily eat it. It is regarded as a serious jjest in New Zealand. The stems have been used in the manufacture of imitation Leg- horn hats. Average number of grains in 1 pound of pure seed, 924,000. Price of seed cjuoted in New York catalogues, $6 per bushel. Weight per bushel, about 10 pounds. No. 31. Aristida fasciculata Torr. Needle-grass. (Fig. 12.) Needle-grass grows from 6 inches to a foot high, and is a njitive of the arid re- gions, from Montana southward to Texas, where it is particularly abun- dant in poor soils, and presents a great variety of forms. It is usually found in dry, gravelly soils on the plains, mesas, and foothills. In the Eastern and Middle States the species of Aris- tida are deemed of little or no value, but in the Southwest, where every mouthful of fodder of any sort has value, they are not wholly worthless. Artiropagated l>y transplanting the roots, which work may be done at any time during the season. After growth has fairly commenced the subsequent development is very rapid, and for this reason it is one of the most important plants of its class for quickly producing scenic elVects or for concealing un- sightly objects. No. 37. Astrebla pectinata F. v. Mnell. Mitchell- grass. A smooth, <'reet grass, 1^ to 3 feet high, with liat. long-pointed leaves and densely llowered terminal spikes or heads. It is a native of Australia, grow-" ing naturally upon the inte- rior })lain8. It is regarded by the stockmen of that country as the best of all native grasses, both for its drought- enduring qualities and for its fattening projierties. If cut just when coming into bloom, it makes excellent hay. The setnl is produced in abnndance, and is easily collected. This may prove a valuable grass for the seniiarid districts of the Southwest. The seeds of this grass, as well as tliose of the closely related Axtrebla triticoides, weic formerly used as food by the natives of Australia. No. 38. Avena americana Si ribn. American Oat-grass.

An erect annual, 2 to 3 feet high, with loose, ojien piiniclcs, 8 to 10 inches long, the whole aspect of the plant closely resembling forms of the cultivated oat. The spikelets are larger, however, and the flowering glumes are covered with long, brown hairs, and have a twisted awn an inch in length. It is a native of the Mediterranean region, but is now widely distributed over grain-growing coun- tries, and with the closely related J. harhata Brot. is especially common in Cal- ifornia and Oregon, and has spread eastward to Minnesota. It is of rare occurrence in the Eastern States. By some this is 8ui)posed to be the original of the cultivated oat (Avena satira), which is said to readily degenerate into it. Avena fatua is in most places regarded as a troublesome weed. When abundant in the grain fields, it occupies the place of better plants, and reduces the gr.ule of the thrashed grain by the admixture of its inferior and lighter seeds. The stiff and twisted awns are injurious to stock, as they freijuently cause irritation of the nostrils and mouths of the cattle feeding upon them. In California the young plants, before the bearded or awned spike- lets mature, are esteemed for grazing and forage. "The use of the Wild-oat, with its brown, hairy seed and twisted awn, as an artificial fly by fishermen, is well known, the uncoiling of the awn when, wetted causing those contortions by which it imitates a fly in trouble." (Hooker.) A form of the Wild-oat with the flowering glume smooth (var. (iJahrescena Coss.) is quite widely distributed on the Pacific Slope, where it has become a most trouble- some weed in wheat fields. Fig. 15.— Wild Oats {Avena fatua) . No. 40. Avena pubescens Linn. Downy Oat- grass. This grass is similar in habit and appearance to Arena fatua, l)ut is much less com- mon. It is a European grass, and. has thence been Introduced into this country. It is occasionally found in the grain region of the Pacific Slope. The soils best suited to the growth of this grass are sandy loams, upon which it is valuable for early mowing and pasturage Under favorable conditions it has produced 15,654 pounds of green fodder, or 5,870 pounds of hay, and 6,860 poundj of after- math per acre. No. 41. Avena sativa Linn. Oats. A well-known erect annual, 2 to 4 feet high, with flat leaves and expanded panicles of rather large pendulous spikelets. There are many varieties, which have been divided into two classes, "panicle oats" with widely spreading panicle branches; and "banner oats" with the panicles somewhat contracted and one-sided. These two races are divided into "chaffy'' and "naked-fruited" sorts; further varieties are established upcwi the color, form, or some special character of the grain. Oats have been cultivated from very early times in Europe, and they 20 form the princii)al grain of such northern countries as Norway and Sweden, and Scotland, and iu these countries boiled oatmeal and oatmeal cakes are impor- tant articles of food. Boiled oatmeal is also much used in this country, espe- cially at breakfast. The grain, however, is principally cultivated here as food for horses. In the Southern States, oats, particularly winter oats, are largely grown for forage. Sown in August, they fiu'uish the best grazing from Octo- ber to the latter part of Aiiril, and will then yield a more certain and a larger crop of grain than spring-sown oats. They are often cut green for soiling and for hay. Oat hay is quite extensively used in the South and in Calif(U-nia. The practice is to cut Avheu the grain is iu the ''dough" stage, or when the straw commences to turn yellow below the head and the leaves are still green. The yield ranges from 3 to 4^ tons per acre, according to the variety and the season. The feeding value of oat hay is higher than that of tinutthy, containing about 8.8 percent of crude protein, and 55 to 05 percent of fat formers, while the latter (timothy) contains from 5 to 7 per cent crude protein, and 45 to 55 per cent fat formers. Among the cereals, oats are the most nutritious, hut oaten Hour lacks the gluten of wheat, rendering the making of bread from it impossible. Oatmeal is richer in nitrogenous matter than soft wheats, and contains more fat than any of the other grains. Russian "quae'' beer is made from oats. No. 42. Avena sterilis L. Animated Oats. A stout, oat-like grass, with one-sided panicles, and very large, awuedspikelets ; the awn is very long, twisted, and "kneed" or geniculate. It is the twisting and untwisting of these awns when exposed to changes of moisture and dryness that has given to this grass the common name of "animated oats." The untwisting or coiling-up of the awn causes the spikelets to tumble about in various directions, suggestive of independent motion or life-like activity. No. 43. Bambusa. Bamboo. The bamboos belong to the Bamhusea, a trihe of grasses numbering about 175 species, chietiy limited to South America, southern and eastern Asia, and the East Indies. There are no Euro]tean species, and only two in North America (see Arundinaria). Of the whole number of species only one is common to both hemispheres. The largest bamboos attain a height of IL'O feet, with a diameter of a foot or more. A South American species has leaves 3 to 12 inches wide and 5 to 15 feet long. In India are extensive bamboo forests, and in countries where these grasses abound they are employed for many jnirposes. They furnish material for the complete construction and furnishing (including domestic utensils) of houses. They are used iu shipbuilding and in the construction of bridges. Buckets, liitchers, llasks, and cups are made from sections of the stems. Baskets, boxes, fans, hats, and jackets are made from split bamboo. Ropes and Chinese paper are made from these grasses. A Chinese umbrella consists of bamboo paper, with a bamboo handle and split bamboo for a frame. The leaves are used for packing, filling beds, etc., and occasionally serve as fodder for stock. The young shoots serve as a vegetable. Tabashir, <>r bamboo maiiua, a silicious and crystalline substance which occurs in the hollow stems of some bamboos, is regarded as itossessing medicinal properties. Good drinking water collects in quantities in the hollows of the internodes of many of the larger bamboos. All sorts of agricultural implements, appliances for spinning cotton and wool or for reeling silk, are often (onstructed entirely from bamboo. Aery many articles of househohl use or decoration made from bamboo have become articles of com- mene in Europe and this country. So many and varied are the uses of the several species of bamboo, that it is possible to mention here only a small part of them. Bamboos are propagated by seed, but more often by cuttings. I'lants from the seed do not attain a sufficient growth to admit (Topi)iiig under 10 or 12 years. 21 No. 44. Beckmannia erucaeformis (L.) Host. Hlongh-grass. (Fig. 16.) A stout, erect, subiifiuiitic perennial, 1 to 4 feet high, with narrow, densely flowered panicles. The leaves are hroad and Hat, and the stems are coarse but tender, becoming somewhat woody when old. It grows along the banks of streams and rivers and frequently follows the course of the irrigating ditches. When young, however, this grass is palatable and readily eaten by stock. In some portions of the North- west, to which region this grass is confined in this country, it often occurs in such (|uantities as to constitute an import- ant part of the forage of low pasture lands. It may be recog- nized by the peculiar, si)ike-like branches of the panicle, which have some resemblance to the rattles of a rattle- snake, and for this reason it is sometimes called "Rattle- snake-grass." It i.s deserving of trial under cultivation for low meadow lands in the more Northern States, and is especially adapted to irrigated alkaline lands. No. 45. Bouteloua curtipendula (Mx.) Torr. Side Oats. ■ (Fig. 17.) This is among the tallest of our species of Bouteloua, the rather stout, tufted stems being from 1 to 3 feet high. It has tough, perennial, fibrous roots, flat, long-pointed leaves, and many short spikes arranged along the upper portion of th<- stem. Its range extends from New .lersey westward to the Rocky Mountains and south- ward through Texas into Mexico. Where abundant, it is said to make fair hay, and the numerous root leaves afford good pastur- age. The hay is readily eaten by stock, but on the range cattle show a decided preference for Blue Grama. Several species of Grama have been successfully grown in small cultures at some of the experiment stations, but none of them, although apparently most valuable as i»asture grasses for the semiarid regions, have been introduced into general cultivation. No. 46. Bouteloua eriopoda Torr. Black Grama. This is one of the species of Grama so valuable for grazing in New Mexico and Texas. The slender stems are 1 to 2 feet high, and from its thrifty habit of growth it forms dense and excellent pasturage wherever it grows abundantly. It is a common grass along the Rio Grande and in the region between the Pecos and the Gila ; also in the Olympia, Guadalupe, and Eagle mountains, and on the Staked Plains in Texas. The woolly-jointed stems at once serve to distinguish this from the allied species of Bouteloua. No. 47. Bouteloua oligostachya (Nutt.) Torr. Blue, or White Grama. (Fig. 18.) This is one of the most abundant and most valued of the Grama grasses, and extends from Wisconsin westward to California, and southward into Texas and northern Mexico. It is a perennial, 6 to 18 inches high, its strong rhizomes and numerous Fig. 16.— Slough-grass (Beckmannia eruece- formig). Fig. 17. — Side Oats {Boute- loua curtipendula). 22 root-leaves forming dense and more or less extensive patches of excellent turf. In Montana it is known as Buft'alo-grass. It frequents the bench lands of th it State, growing at elevations of from 3,000 to 4,000 or 5,000 feet, and not infre- quently covers wide areas. Xo other grass better withstands the tramping of stock, and it is unsurpassed for grazing purposes. In the early dajs in the Southwest it formed a large proportion of the hay delivered at the various mili- tary posts and stage stations, and was considered the best ol)tainable there. Like the true Bufl'alo-grass, it cures during the dry season in the turf into perfect hay, losing none of its nutritious properties. No. 48. Bouteloua polystachya Torr. Low Grama. This is a small, slender grass, of good quality. It is one of the smallest of the Gramas, aud only occurs sparingly here and there in scattered tufts. It rarely exceeds 6 inches in height, and is confined to the arid regions of the Southwest. No. 49. Bouteloua repens (HBK.) Scribn. Creep- ing Granui. A common grass in the vicinity of Acapulco, Mexico, where, according to Dr. E. Palmer, it occurs on the highest mountains and down their stony slopes to the water's edge. Greedily eaten by stock. No. 50. Bouteloua texana Watson. (Seed Mescjuit.) This is a small but excellent grass, common about 8an Antonio and at other i)oints in Texas, chieHy along the Rio Grande. It is recognized as an important grass in the stock ranges. No. 51. Brachypodium japonicum Miq. Japanese Wheat- grass. A promising Japanese perennial, closely resembling Bearded Wheat-grass (Agropi/ron caninum), but of rather stronger growth. It was iutroduced into California by the Agricultural Experiment Station of the University of California, at Berkeley, from New Zeahmd, in 1886, and the first seed was dis- tributed in California in 1889. It has been culti- vated with success at a number of points in Cali- fornia and at several of the exi)erimeiit stations in the East. In tlie Southern States it is regarded as a valuable grass for winter, grazing, as it makes its best growth during the cooler months. Small Quaking-grass. (Fig. 19.) An erect ])erennial, from 1 to 2 feet higli, introduced into this country from Europe ]»ecause of its pleasing ornamental apitearance. It has escapiMl from cultivation in many places, and has becomt; sparingly naturalized. It is occasionally e and is recommended as an admixture for i)as- tures on dry, thin soils. liriza minor is a smaller and niorc^ delicate annual species, .also cultivated occasionally as an ornamental and for dry bouquets. /!ri:(i maxima, also an annual, is a larger ornamental species.

An erect perennial, 2 to 5 feet high, with strong creeping rootstocks, and a loose open panicle, 4 to 6 inches long. A native of Europe introduced into this country by the Agricultural Experiment Station of the University of California about 1880,. which gives considerable promise of value both for haj^ and pasturage. It is strongly stoloniferous, and quickly makes a thick, firm turf. It appears to' grow with equal vigor in Canada and in Tennessee, remaining green through- out the winter season in the latter Stiate. The strong p«rennia.l character of Fig. 19. — Small Quaking-grass (Bnza media). Fig. 20. — Smooth Brome-grass (Bromus inermis). this Brome-grass and its unusual drought-resisting powers are qualities which recommend it for general cultivation, particularly in the semiarid regions of the West and Northwest. It thrives well on dry, loose soil, but of course the better the soil the greater the yield. Its nutritive value is comparatively low, and before undertaking its cultivation the fact should be remembered that it is somewhat difEcult to eradicate when once established, although by no means so difficult as Couch-grass or Johnson-grass. In Europe it is classed among the best hay grasses. The seeds are quoted in New York catalogues at from $20 to $22 per 100 pounds. A bushel weighs about 14 pounds. Sow three bushels to the acre if sown alone. In this country the yield of seed per acre has been 600 pounds, which at the prices named would make it a very profitable crop. Pro- fessor Fletcher, of Canada, reports a yield of 3f tons of hay per acre. 24 No. 55. Bromus pumpellianus Scrihn. Western Brome-grass. A native of tlu^ Northwestern States in the Rocky Mouutaiu region, extending into Canada. In habit of growth it closely resembles Hungarian, or Smooth Brome- grass (B. inermis), and is doubtless equally valuable. Prof. .Jame.s Fletcher, who has cultivated this grass at the experiment station at Ottawa, Canada, says, "This is a very valuable grass, producing an abundance of leaves, continuing in flower for a long time, and giving a heavy aftermath." No. 56. Bromus racemosus Linn. Upright Chess. An introduced annual, 1 to 3 feet high, with more or less spreading and nodding panicles and smooth sjiikelets. This is a very common grass in cultivated lields and waste places, and is often mistaken for Chess, from which it differs chiefly in its narrower pauides and .straight awns, which are nearly as long as the Fio. 21.— Chess {Bromiu seealinui). Fig. 22.— Rescue-grass (Bromux xmioloides) . flowering glumes. This grass has become very common in certain .sections, par- ticularly in the South. A lield of it presents an attractive appearance, and the hay produced is of good quality. No. 57. Bromus secaliuus Linn. Chess; Cheat. (Fig. 21.) A well-known, weedy, annual grass, introduced into this country many years ago, and now common in grain fields and waste lauds. The panicle is spreading and more or les.s drooping, and the awns of the flowering glumes are usually much shorter than the glumes themselves and more or less fltjxuose. The idea that Cheat or Chess is degenerated wheat has no foundation whatever in fact. Only Cheat seeds will produce Cheat, and it is certain that wherever these plants appear they were preceded by ( "heat seeds, which may have been introduced with the grain sown, or brouglit by birds or animals from other lields. Cheat and wheat are only remotely related; they belong to quite distinct tribes in the grass 25 It grows to the height Fig. 23.— Buffalo-grass (Bul- hilis dacti/loicleg) . a , female plant; b, male plant. family; wheat is less likely to change into cheat in a single generation than into the more nearly allied oats, or than wheat is to change into barley, with which it is very closely related. No. 58. Bromus unioloides Willd. Rescue-grass. (Fig. 22.) This Bromus, which is a native of South America, and probably also of the extreme southwestern ijortion of the United States, is a strong-growing grass, with rather broad, much flattened, usually bearded spikelets. of 1 to 3 feet, and in the more vigorous plants the branches of the nodding panicle are widely spreading. It grows rapidly, seeds freely, and dies after seeding. If, by frequent mowing or close grazing, it is prevented from going to seed, its duration may be continued over two or three years or more. If the seeds are allowed to fall, as they frequently do when mature, young plants soon appear, and a fairly continuous growth of this grass may thus be maintained. In many parts of the Southern States, where it has been most cultivated, it has come to be regarded as one of the best winter grasses, as it makes its chief growth during the cooler months of the year. Sow in Augnst or September, at the rate of 30 to 40 pounds to the acre. No. 59 Bulbilis dactyloides (Nutt.) Eafin. Buffalo- grass. (Fig. 23.) This is the true Bnff'alo-grass of the Great Plains region, which is reported to have been much more abundant and more widely distributed in times past than it is at present. Now, however, it is known to extend from the British Possessions southward into Texas, where it is considered an invalu- able grass and one of the best constituents of sheep pastures. It has a low habit of growth, rarely more than 5 or 6 inches high, and pro- duces numerous creeping and widely spreading branches or stolons, which root at the joints, each joint forming a new tuft, and in this way the grass often covers large areas with a close mat of fine-leafed herbage, which is greatly relished by all grazing animals. As a winter for- age, it is without an equal. The habit of growth of this plant is very similar to that of Bermiula-grass, but the stems and leaves are much finer and the turf formed more compact. Live roots transplanted from Nebraska to the grounds of the Department of Agriculture at Washing- ton, D. C, have groAvn with remarkable vigor, and it may be possible to utilize this most palatable and nutritious grass in portions of the Eastern or Southern States. No. 60. Calamagrostis canadensis (Michx.) Beauv. Blue- joint. (Fig. 24.) A native grass common in the Northern and Northwestern States, extending clear across the continent, usually growing in moist meadows. The leafy stems are 3 to 5 feet high, and the open brown or purplish panicles have some resemblance to those of Redtop. Occasionally it is found occupying considerable areas to the exclusion of other grasses, and under such conditions it yields a large amount of excellent hay, highly prized by farm- ers and eaten with avidity by all farm stock. This grass grows naturally on low, moist meadows, and has succeeded well under cultivation. In the northern por- tion of the United States its more extended culture for hay is recommended. Fk;. 24.— Blue-joint (Gal- amagroetis canadensis). 26 No. 61. Calamagrostis cinnoides (Mulil.) Spreng. Reed Bentgra.ss. A stout, reed-like grass, 3 to 5 feet bigh, not infrequent in low, moist grounds and swamps, ranging from New England southward to Tennessee. No attemi)t& have been made to cultivate it, and little is known of its agricultural value. Probably of some use for low woodlands where grasses are desired for pasturage, and if it will thriv^e in the open it would make a most excellent hay-grass for low meadows. No. 62. Calamagrostis hyperborea americana (Vasey) Kearu. Yellow-top. A very common grass in low meadows and shady river banks throughout the North- west. It artords a large amount of excellent hay if cut in proper season. A good grass for cultivation in moist, sandy meadows. No. 63. Calamagrostis neglecta(Ehrh.)Gaertn. Pony- grass. A rather slender, erect i)erennial, with narrow leaves, and a contracted, densely flowered, brownish panicle, 3 to 6 inches long. A native of Northern Eurojie and North America, ranging along our northern borders from Newfoundland and Maine to tlie Pacific, being most abundant in the Rocky Mountain region. Under experimental cultivation it has succeeded well. It is a productive grass, much liked by stock, especially horses, and is deserving a place among the cultivated species. No. 64. Calamagrostis suksdorfii Scribn. Pine-grass. A rather slender, erect grass, 2 to 3 feet high, with smooth stems, narrow leaves, and contracted, usually pale, straw-colored panicles. A common grass in the Northwest, growing in low pine woods or on moist mountain slopes. It is said to be one of the most common grasses in Washington, and it presents all the ([ualities of an excellent hay or pasture grass. No. 65. Calamovilfa lougifolia (Hook) Scribn. Sand- grass. (Fig. 2.5.) A stout, long-leafed grass, 1 to 4 feet high, growing in sands or sandy soil along the siiorcs of the (ireat Lakes and iu the Missouri region of the West, ex- tending southward to Kansas. Its very strong and far-reaching rhizomes or creeping "roots" make this an exceedingly valuable grass for binding drifting sands, or those subject to wash by swift currents or the beating of the waves. As a sand binder for interior regions of the country this grass is probably unsurpassed. Its bmg, tough leaves suggest a possible vahn- for jtajier making. No. 66. Campulosus aromaticus (Walt.) Sdribn. Toothache-grass. (Fig. 2t!. ) A perennial grass with erect stems 3 to 4 feet high. Native of the Southern States from Virginia southward, growing in the wet pine barrens, possessing no agri- cultural value, liut rather cnrinus in ajtpearance. The strong rootstocks are leuion-scented and have a pungent taste. No. 67. Ceuclirus echinatus Linn. Cock-spur. A rather stout annual, with branching culms 1 to 2 feet long, and dense heads or spikes made n\> of 20 or more globul.ir, spiny burs containing the sj)ikel<'ts. It is a weed of the fields and waste places of the Southern and .Southwestern States. Fig. 25. — .-^aiul-jri-jms (Oalamo- vilfa lumjifolia). 27 No. 68. Cenchrus tribuloides Linn. Saud-bur. (Fig. 27.) A widely distributed grass growing in sandy soils along river bants, tie seasliore and more or less scattered tbroughout tbe interior of tbe country in sandy dis- tricts. It is one of tbe w orst of annual weeds wherever it becomes abundant. The prostrate branching stems are 1 to 2 feet long ; tbe spikes are composed of 10 to 15 strongly spiny burs, which readily become detached and adhere to passing objects. No pains should be spared in efforts to exterminate this grass wherever it makes its appearance. No. 69. Chaetochloa glauca (Linn.) Scribn. Yellow Foxtail. (Fig. 28.) An erect annual, 1 to 2 feet high, with flat leaves, and a bristly, cylindrical, s])ike- like, densely flowered panicle 1 to 3 inches long.

It is especially common in the Southern States, where it continues t<> bloom throughout the season, from June to Octo- ber. It is distinguished from Seta^-ia viridis by its somewhat larger sjiikelets and more widely spreading yellowish bristles. No. 70. Chaetochloa italica (Linn.) Scribn. Millet; Hungarian-grass. (Fig. 30.) This grass, in some of its varieties, has been cultivated in the East for many centu- ries, and in some parts of India and Trans-Caucasia it still forms an important article of food. Its culture extends back to an early date in Egypt, and in the lake dwellings of the stone age it is found in such quantities that it must be regarded as tbe main bread supply of the prehistoric peoples (Hackel). In Europe and in this country it is cultivated to some extent for fodder and for the 28 Beed, the latter being used chiefly for fowls. It grows rapidly, and may he cnt within sixty or sixty-live days from the time of sowing. If used for fodder, it should he cut just as it begins to head, before blooming, for when more advanced it is apt to be injurious to stock fed upon it. When cut in good season it is one of the most valuable of soiling plants. German Millet, Cluvtochloa germanica (fig. 29), is only a variety of ChwtocMoa italica, distinguished by its smaller, more compact, and erect heads, the bristles of which are usually ])nrpli8h.

It grows in tufts like Deachamptiia caapitoaa, and is Fig 35. — Crowfoot-grass ( Dacttfloctenivm (vgypt'nna) . 33 more common in the Eastern States than that species, but is even less valuable for meadows. It is, however, of some value for Avoodland pastures, as it will grow very well iu the shade. It extends southward along the mountains into North Carolina and Tennessee. Its range westward is limited. It has a record of producing- 12,209 pounds of rowen and 3,318 of dry hay per acre. The price of seed quoted iu New York catalogues is $15 pur 100 pounds. No. 86. Distichlis spicata (L.) Greene. Salt-grass. (Fig. 37.) An upright, wiry grass, 10 to 20 inches high, with strong, extensively creeping root- stocks. Common along the coast on both sides of the continent, and abundant in the alkaline regions of the interior, where it is often found covering consider- able areas to the exclusion of other grasses. It thrives even iu ground heavily crusted with alkali and other salts sufficient to destroy almost any other kind Fig. 36.— Wood Hair-grass (Deschampsia Jlexuosa). Fig. 37.— Salt-grass ( Distichlis spicata). of vegetable growth. Prospectors and miners consider its presence a sure sign of water near the surface, and when crossing the desert select spots where it grows to dig for water (Orcutt). In fanning lands it is deemed a nuisance, for its tough, matted roots make a sod almost impossible to break up with a plow. Although sometimes eaten by stock in the absence of better sorts, it has little agricultural value. It is a good grass for binding loose sands or soils subject to wash. No. 87. Eatonia obtusata (Michx.) Gray. Early Bunch-grass. A tufted perennial, 1 to 2 feet high, with flat leaves and rather densely flowered nodding panicles. This is a native species, growing usually in moist soil, and ranging from New York to California and so>uthward. A tender grass, readily eaten by stock, which, when abundant, supplies considerable native forage of good quality. 4393— Eo. 14 3 34 No. 88. Eleusine coracana (L.) Ga-rtn. African Millet. An erect auniuil grass, 2 to 4 feet high, closely related to and much resembling our common crowfoot {Eleusine indica), but of rather stouter habit and with larger spikes and seeds. It is cultivated in India, southern China, Japan, and in many parts of Africa for the grain, which is used as food. It forms the principal food of many African tribes. In spite of the bitter taste of the Hour, a kind of bread or unleavened cake is made of it. Beer is brewed from the grain in Abyssinia. Said to yield good crops, even on very poor soil, and may be culti- vated in the same way and for the same purposes as millet. The seeds are marked with very tine, comb-like lines. No. 89. Eleusine indica (Linn.) Ga^rtn. Goose-grass. (Fig. 38.) A coarse, tufted annual, with erect or spreading stems, 6 inches to 2 feet high ; spike- lets arranged in a number of spikes which are clustered at the top of the stem. This grass is distributed throughout the warmer countries of the globe, and is particularly abundant in the Southern States, growing in culti- vated grounds about dwellings, etc. It has somewhat wiry, flattened stems, many springing from a single root, and rather thick leaves. Some authors have spoken of it as being nutritious and good for grazing or soiling and for hay, but it is more generally regarded as a weed, and often a troublesome one in door- yards or lawns. No. 90. Elymus areuarius Linn. Sea -Lyme-grass. (Fig. 39.) A stout, coarse grass, 2 to 8 feet high, with strong, creeping rootstocks, smooth stems, long, rigid leaves, and dense terminal spikes 6 to 12 inches long. The spikelets are about an inch long and three- to four-llowered. This grass is common along the sea- coast of northern Europe, our north Atlantic coast, and on our Western shores from Santa Cruz, Cal., north- ward to within the Arctic zone. It is one of the best grasses known for ))iuding the drifting sands of the coast, and in northern Europe has been cultivated along with Beach-grass for this jmrpose. These two gra.sses when eoiiibiiied seeiu admirably ada])ted for the pur- po.sc of forming a barrier to the encroachuient ol' the sea ; the sand that Beach- grass arrests and c(dlects about itself the Lymc^-grass secures and holds fast. The seeds are used for food by the IMgger Indians of the Northwest, and as the grass springs up around their deseited lodges it is called by the settlors "lianche- riii'' grass. This J>yme-grass is usually regarded as possessing little or no forage value, but in very moist climates or under certain favorable conditions it may yield a valuable fodder, for w hen young the grass is tender and nutritious. No. 91. Elymus canadensis J^inn. Wild Rye. A rather stout, smooth ])crcnuial, 3 to 5 feet higli, with broad, llat leaves, (> to 12 iuilies long. The bearded spikelets are arranged in a terminal spike or " head," which has some resemblance to a head of rye. Common in low thickets and Fiii. ;i».— Goo.se-gra8.s (Eleusine indica). 35 along streams in rich, open woods thronghout tbe country. In the Northwest it is regarded as of some agricultural value; its cultivation is evidently worthy of trial, for if it could be successfully grown its yield of hay would be large, and, judging from appearances, the hay would be of good quality. No. 92. Elymus condeusatus Presl. Giant Eye-grass. The largest of the native Rye grasses, growing to the height of 5 to 10 feet. Common in the Eocky Mountain regions and on the Pacific slope, usually growing along rivers or streams the banks of which are protected and held together by the strong, spreading rootstocks of the grass. This grass is useful for holding the sand on railway banks, etc. When young this grass makes excellent hay, and when allowed to stand it affords a considerable amount of fodder for stock on the winter ranges. The seeds are used for food by the Indians. No. 93. Elymus macoimii Vasey. Maconn's Rye-grass. A perennial grass, found (^uite abundantly in moist meadows, in the gravelly foothills of the northern Eocky Mountains. The culms are leafy, and this grass contributes cxuite largely to the nati\e hay cut by the ranchers of the North- west. It is apparently a very valuable species. No. 94. Elymus mollis Triu. Soft Sea Lyme-grass. A grass which closely resembles and has the same habit of growth as Elymtis arenarius. It is distinguished by having the stem soft-downy just be- low the head or spike and in having five to seven flowered spikelets, the outer glumes of which are broader and five- to seven-nerved. This grass occurs along the shores of the Great Lakes and northward on both the Atlantic and Pacific coasts. No. 95. Elymus triticoides Xutt. Wild Wheat. Fig. 39.— Sea grass (Ell/ in nariui). Lyme- iis are- r>y some this has been regarded as a small, reduced form of Ehimiiv condensatu!^, mentioned above. It grows to the height of 2 to 3 or 4: feet and is native of the Eocky Moun- tain region and Pacific Slope, extending eastward nearly to the Mississippi. While it is a grass of good appear- ance and possibly of some agricultural value, no attemjits have been made to cultivate it. No. 96. Elymus virginicus Linn. Terrell-grass. (Fig. 40.) The most common of our native species of Lyme-grass, growing along streams, the borders of woods and thick- ets, more rarely in the open ground. It is an erect, smooth grass, 2 to 3 feet high, with rigid terminal spikes, which are often partly included within the upper leaf- sheath. This grass has the appearance of possessing some agricultural value; it forms an inferior turf, and by the time it blooms all the lower leaves are usually dead. When young it doubtless possesses some value as a native pasture grass. In Kansas, South Dakota, and Nebraska it is regarded a valuable grass for wood- land pastures. Fig. 40. — Terrell-gi-ass (Elymus virjiiiiciis) . 36 No. 97. Epicampes rigens Benth. Deer-grass. (Fig. 41.) A stout, erect grass, 3 to 4 leet Ligh, with rigid, wiry stems, and a very long, narrow, densely llowered, spike-like panicle. This grass is not uncommon in Arizona, southern California, and New Mexico, growing in sandy soil. It is regarded as one of the best native dry-land grasses, and is closely grazed wherever stock tan get at it. The roots of E})!- campes mucroura — Mexican Broom-root or Mexican Whisk — are used in making brushes and are exported from Vera Cruz to Europe fof this purpose. No. 98. Eragrostis abyssinica Link. Teft'. A brauchiug. leafy annual, 2 to 1 feet high, with widely spreading capillary panicles of many spikelets. This grass grows readily from seed, wiiich is produced abund antly, and it may be of some value for hay in parts of the Sou til or Southwest. In northeastern Africa, when; the grass is apparently native, the grain is extensively used for food, l)eing made into l)read, which possesses a slight but agreeable acid taste. There are two va- rieties cultivated, a white and a red variety, the for- mer being much superior to the latter and used only by the higher classes. It is sometimes grown in gar- dens for the elegant pani- cles, which are used in bou(iuets. KviKjrosUti neo- mexicana Vasey, with the general habit of growth of Teft", occurs in New Mex- ico, si)ringiug up after rains, particularly in the region about Doming, 1^ where it is called "Crab-grass." It is an annual, growing to the height of 2 to 4 leet, with widely spreading, many llowered panicles, and is largely cut for hay. No. 99. Eragrostis major Host. Stink-grass. (Fig. 42.)

No. 100. Eragrostis obtusiflora (Fourn.) Scribn. Mexican Salt-grass. A rigid perennial, 12 to 18 inches high, with strong and extensively scaly rootstocks, stiff and sharp-pointed leaves, anil nujre or less sjireadiug i)auicles. Abundant in the highly alkaline soils ol" Suli»hur Springs Valley, Arizona, where the large rootstocks serve to bind the shifting sands. In the absence of other grasses it is eaten by stoiik. No. 101. Eragrostis pilosa ( Linn.) Hoauv. Slender Meadow-grass. A slender l.raucliing annual, (I to 18 inches high, with narrow. Hat leaves and capil- 37 lary, open panicles. This grass is widely distributed throughout the subtropi- cal aud warmer temperate regions of both hemispheres. In this country it has received no attention or is regarded as little more than a w eed, but in Australia and India it is spoken of as being an excellent fodder grass, and the seeds are eaten by the natives of Ajmere, India. No. 102. Eragrostis purshii Schrad. Southern Spear-grass. A native annual, similar in appearance to Eragrostis pilosa, and growing in similar situations. It is common from the Middle States southward, and extends south- westward into Texas and Arizona, where it exists iu a great variety of forms. It grows to the height of 1 to 2 feet. It is nowhere considered of any agricultural importance. No. 103. Erianthus ravennae Boauv. Plume-grass. A stout grass growing to the height of 8 or 10 feet, with large and plume-like pani- cles 10 to 20 inches long, resembling in some degree Pampas-grass.' t^ultivated for lawn decoration, as is also the variety with variegated leaves. A nat'ive of the Mediterraueau region. ^^>,;. \ ' ' ' :- ^^^ No. 104. Erianthus saccharoides Michx.

Of no agricultural value, but deserves notice as an orntsj^^fal grass for lawns and gardens. No. 105. Eriochloa aristata Vasey. Mexican Everlasting-grass. A branching leafy annual, 2 to 3 feet high ; native of Mexico. Seed of this grass was obtained by the Dei»artment in 1888. It was cultivated in the grass garden located at Starkville, Miss., by Prof. S. M. Tracy, who says that it is a much more promising grass than E. annulata, more hardy, less injured by drought, aud produces a heavier growth. It will make two good crops of hay annually in the South, the best crop being from the second growth, which is ready to cut in October. The grass produces an abundance of seed and reseeds itself, making its production comparatively inexpensive. No. 106. Eriochloa punctata (Linn.) Hamilt. Everlasting-grass. A quick-growing, smooth, succulent perennial, 2 to 3 feet high, with flat leaves and narrow panicles 2 to 4 inches long. Widely distributed within the tropical and subtropical regions of both hennspheres. In Australia it is regarded as an excel- lent pasture grass, lasting all the year round and well liked by stock. The seed, which is produced abundantly, is easily gathered. This grass deserves the attention of Southern dairymen. In Arizona it grows throughout the valleys iu irrigated soil, or iu the rich moist places of the plains, yielding abundant herbage eagerly sought by all kinds of stock. No. 107. Eriocoma cuspidata Nutt. Indian Millet. (Fig. 43.) A grass of rather striking appearance, 1 to 2 feet high, widely distributed through- out the Rocky Mountain region from British America southward to Texas and New Mexico, eastward to the Missouri, and Avestward to the Sierras of California. It grows iu dry sandy soils, forming bunches of greater or less size, and from this habit of growth it has been called, along with a number of other grasses, "I'.unch-grass." It thrives iu soil too dry and sandy for the growth of most other grasses, aud is much esteemed for grazing in the regions where it abounds. In New Mexico this grass is by some deemed superior to grama, on account of its large and nutritious seeds or grains, which are used by the Indians to some extent for food. 38 No. 108. Enchlaena mexicana Rchrad. Teosinte. (Fig. 44.) A stout, leiil'y, auuiuil gra.ss, N to 10 or 12 feet high, resemljling Indian corn, to which it is hotauicallj" closely related. The variety 7s. Jnxiiridns, of the seed cata logues, which has been cultivated in various parts of the South and West, has a habit of tillering, or sending uji many — 20 to 50 — stalks from the same root (Plate III, fig. 1). From this habit the bulk of fodder produced to the acre is very large, probably uncqualed by any other grass. It is liked by all kinds of stock, and has especial value as a green fodder when other forage is dried up. It may l)e cut several times during the season, but nearly as good results will be obtained from a single cutting, made before there is any frost. The stalks are tender, and there is no waste in the fodder when dry or green. One pound of seed to the acre, planted in drills 3 feet apart and thiimed to a foot apart in the drill, is recommended. It is a native of the warmer portions of ilexico and Central America. The seed rarely matures north of southern Florida. No. 109. Festuca duriuscula Lam . Hard Fescue. A slender, densely tufted, perennial grass, 1 to 2 fe(!t high, with numerous very iine radical leaves and open panicles. This is one of the Fm. 43. — Indian Millii (Eriocoma cutpidata). Fig. 44.— Teosinte (Euchlcena mexicana). foiiiis of Slieep's Fescue, mid is of little value except in pastures. Its particular merit lies in i.ts iibility to thrive on dry sandy soils uuli( for tlie growth of bet- ter grasses, and it Avell resists long periods of summer drotight. It is well ada))ted to the cooler and mountainous regions of our country, being a native of the cooler temperate regions of both hemispheres. On well-manured, clayey l:ind this Fescue has j)ioduccd upon :i single acre 18,37arnel. An annual grass, 2 to 3 feet higii, having a general re- semblance to Italian Rye-grass, but usually stouter, more strictly erect, with longer glumes and larger seeds. It has been introduced into tills country with the seeds of other grasses, and is occasionally met with in grain lields and about dwellings. The grain contains a narcotic or jiolsonous principle, whi leafy tutts 1 to 4 inches high. Similar in habit to Bermuda, but more deli- cate. According to Dr. E. Palmer, this is one of the most important grasses of M(!xico. Growing close tn tin' ground, it forms a tliiit to the last aud growing in similar .silnatioDS in the Northern States, exteudiug southward to Peuusylvauia and westward to Kansas. It is less common than P. americana. It has received no attention from the agricul- turist. The nodding panicles of rather large spikelets are sometimes gathered for dry houquets. No. 152. Panicularia fliiitans (Linn.) Kuntze. Floating Manna-grass. (Fig. 59.) This gras.s grows to the iieiglit of from '.^ to 5 feet, and has a nariow panicle composed of rather few long aud narrow or cylindrical spikelets. It is a cosmopolitan species, found in all temperate regions of the world, and is regarded as one of the best fodder grasses for swampy meadows. In some ])arts of Europe the seeds are 'fathered ami used for human I'ood in the form of sou])S and gruels. Via. .')8.— Rattlesnake-grass (PainmUiiiii nnia cicns-is).

A leafy jiereunial, 1 to 3 feet liigh, with cxi»anded nodding jianicles of small spike- lets. This is a com n species in low meadows aud moist grounds, extending from New ICngland southward to the (iiilf States and westward to the I'acilic coast. It is a good fodder plant for moist meadows, \aries greatly in size, aicording to soil and location. I'aniciihiria amerUana and I'aniritlaria neriata furnish food for water fowl during the fall migrations and are valuable in ganic )>reser\es along with Zizania aiiuatica. No. 154.

Panicum capillare Liuu. Okl Witch-grass. An annual, with usually coarse, branching stems, 1 to 3 feet long, hairy leaf sheaths, and widely spreading panicles. Grows in cultivated grounds, wh(^re it often becomes a somewhat troublesome weed. Being an annual, however, it is easily eradicated. Possesses no value for fodder excepting for fall feed on stubble. No. 157. Paiiicuin ciliatissimum Buckl. Iiidhm Wheat. A more or less extensively creeping perennial, Avith short leaA^es and upright dowering stems, 6 to 18 inches high. The panicles are narrow and few flowered, and in the prostrate forms usually ^lartly included Avithin the leaf sheaths. This grass is a native of Avestern Texas, and doubtless possesses sonu; agricultural value for the drier regions of the Southwest. The creei>ing stems resemble someAvhat those of Bermuda-grass, but the leaves are usually more crowded and broader in proportion to their length. 52 No. 158. Paniciim colonum Linu. Shama Millet. A native of the tropical and warmer temperate regions of the Old World. In northern India it is considered one of the best fodder grasses. Introduced into the Southern and Southwestern States, where it is occasionallj^ found in waste grounds about dwellings. It is closely related to Panicum critH-galli, differing from that grass iu its smaller size and more simple iuHorescence. The stems and leaves are tender and readily eaten by stock. In India the grain, which is produced abundantly, is sold in the markets and used for food. No. 159. Pauicum crus-galli Linu. Barnyard-grass. (Fig. 63.) This well-known annual of rank growth is common in rich, cultivated ground, espe- cially around dwellings. There are stsveral forms presented by this species. That growing as a weed around barn- yards and dwellings, in cnlti Abated grounds in the Atlantic States, was probably introduced from Europe. There are, however, several native varie- ties, or possibly good species. One of these occurring in the brackish marshes or meadows along tiie seaco.ist, grows to tile height of 3 to 5 feet, with the lower leaf sheaths verj' hirsute, and the spike- lets loug-awned. A tall, smooth form occurs in New Mexico, Arizona, and the Mohave desert region, springing up after the summer rains in all swampy places or lowlands. It grows to the height of t> or 7 feet, and its seeds, which it produces abundantly, are collected by the Mohave Indians, ground into Hour, and cooked for food. The poorer classes of India also use the grain for food. A variety introduced from .Japan has been culti- vated at some of tlie ex})eriment stations and treated as a millet. At the Hatch Experiment Station, iu Massachusetts, the crop produced was very uniform, averaging 7 feet in height. The yield was at the rate of 11,207 i)ounarts of the world is large, and includes many very different species, whose grain, however, is used for human food. Most of the so-called millets belong to the genera Chatochloa, ratiicum, and Paspahim. They form the princij»al food grains of the natives of many parts of Africa and Asia. It has been estimated that the millets feed one-third of the human race. No. 166. Pauicum molle 8w. I'ara-grass. A rather coarse, reed-like perennial, 4 to 6 feet high, with hairy nodes, and narrow, lax i»auicles. fi to 8 inches long. It is cultivated in ."^outli America, and in the West Indies and Mexico, and has been introduced into some of the Gulf States. It is grown with success on the high pine ridges of Florida, and wherever culti- vated it is most highly esteemed and regarded as a very fattening pasture gra.ss. How far to the north this grass may be grown successfully does not appear to have been determined, but it is hardy at the Cai)e of Good Hope and other far extra troi)ical regions (Barou von Mueller). It is ]>ropagated either by seeds or root cuttings. No. 167. Panicuni obtusum II. r>. K. Vine Mesqnit. A stiilonifcroMS grass, the runners attaining a length of 8 to 10 feet, the upright llowering culms 12 to 24 inches high. This grass ranges from Colorado to Texas, New Mexico, Arizona, and southward into Mexico. It is usually found in irri- gated lands or in the low, damp soil of the valleys, most frequently under the shade of trees and shrubs. No attempts have l>een made to cultivate this grass, but its appearance and habit of growth indicate an agricultural value of suffi- cient importance to call for experiments in its cultivation. In New Mexico this species is calhd "Wire-grass.'" No. 168. Panicum plicatiim Lam. Palm-leafed Grass. A broad-leafed perennial, 3 to 4 feet high or more, native of India. The leaves are elegantly striate and nsualiy ]dicate, giving to the grass an unusual and at the sanu^ time attractive appearance. It is a favorite ornamental for greeidiouse culture. No. 169. Pauicum proliferum T>am. Sprouting Crab-grass. A smooth and usually unn h-branched native annual, with rather coarse, spreading or ascending stems 2 to (5 feet long, flat leaves, and diffuse terminal and lateral panicles. It grows naturally in moist, rich soil along the banks of streams and rivers, around the shores of ]»onds jind lakes, and in the South is often abundant in rich, cultivated tields, growing with Crab-grass. The stout, succulent stems .•lie sweetisli and much liked by h<>r>es and cattle. Its r.inge is from Maine to -Nebraska, and southward to the (Julf, blossuming in tin* latter part of summer or early autumn. The spontaneous growth of this grass in cultivated tields after the reniov.d of crops is of some value for hay or pasturage, but its cultivation can not l»e recommended in view of the fact that we ha^e many .inuual grasses much sui)erior to it. In the Northern and Middle States it is da.ssed with the weeds. No. 170. Panicum repens Linn. Creeping Panic. An oxten.sively creeping grass, with rather stilV upright stems, 1 to 2 feet high or less. It is common in the maritime districts in southern Asia, northern Africa, 55 sonthcrn Euroi)o, and Australia. It is also found along tbo shores of tlic South- ern States bordering tlw Oiilf, extending westward to Mexieo. It has no iigri- cultnral value, but is a natural sand binder. Upon the sandy islands lying off the Gulf Coast it grows abundantly nyjon the outside of dunes, protecting them from the action of the winds and waves. No. 171. Panicum sanguinale Linn. Crab-grass. (Fig. 65.) A well-known annual, coninion in nearly all parts of the United States, growing in cultivated fields and about dwellings. It is a weed in gardens and among hoed crops. In grain lields after harvest it fre- quently springs up in such quantity, particularly in the Southern States, as to yield one or even two good cuttings of hay. This spontaneous growth affords excellent pasturage, as well as hay of first quality if properly cured. The stems are much branched, and in good soil attain a length of .3 to 4 feet. This grass contains little fiber, and dries ([uickly when cut, but if iifter cutting it is wet liy rains or heavy dews its value for hay is almost wholly destroyed. In Bohemia, Crab-grass is cultivated upon sandy soils and the grain is used for food in the form of nnish or poiridge. No. 172. Panicum sero- tinum (Michx.) Trin A species related to Vrah-grai^^ (ranicum sangiiitialr), common in the Southern States near the (inlf, dis- puting with Louisiana-grass the claim of being the most valuable native pasture grass of that section. It is ])robably a bienniaL It is much like Crab-grass, sending out leafy, creeping shoots at every joint, but is snuiller in every way, with shorter and more hairy leaves of a lighter green color. It is invaluabh^ for pasturage, forn\ing a close turf, and driving out nearly all other i)lants. It grows best in sandy soil where there is a little moisture. No. 173. Panicum spectabile Nees. Angola-grass. A stout grass, 3 to 5 feet high, with rather broad and long (I to 2 feet) leaves, an extensively, making this grass particularly valuable for binding banks of viverS and ditches where the water supply is 60 ample. It does not attain its full size until the second year, and if designed for bay should be cut before liowiring, for when fully luature the stems become woody and are too hard to make good fodder. The seed, which matures in .July and August, is easily gathered. Good seed should have 95 per cent purity and 60 per cent g<'rmination. It may be prop- agated by seed or by cuttings of the rootstocks, these being laid down at intervals of 1 foot, and slightly covered. The retail price of seed quoted in the'New York market is $35 per 100 ])i)Uiids. A variety with white-striped leaves, called Rib- bon-grass, is cultivated in gardens for ornament. No. 191. Phalaris canariensis Linu. Canary-grass. (Fig. 72.) An erect annual, 1 to 3 feet high, with flat leaA'es, and dense, ovoid ]ianicles or heads about an inch long. This grass is appar- ently a native of the warmer countries of Europe, al.so of north Africa and western Asia. It has become widely dis- tributed throughout the warmer temperate and tropical re- gions of the world, including Australia. Cultivated in Ger- many and southern Euro])e. It has been introduced into this country, and is occasionally cultivated for its seeds, which are used for bird food. The flour from the seeds is utilized in certain processes of cotton manufacture (weaver's glue), and is even employed in tlio making of some kinds of cake. It is frefjuently met with iu waste grounds Fio. 72.— Canary- about dwellings in the vicinitv of gr.-is.s (I'halaris ^^^^^ canariensis). No. 192. Phalaris caroliniaua Walt. Southern Canary-grass; Apache Timothy. This and Phalaris (itif/iisia (Fig. 73) have usually been regarded as one species, the latter as avarietj- with more elongated heads and rather stouter growth. Both the species and variety are perennials, ranging from South Carolina to Florida and westward to Texas. Arizona, California, and northwaidon thel'acilic slope to Oregon. I'halariifanyusta. a stout grass. 2 to 5 iereading annual, with erect or ascending somewhat flattened stems, 2 to 12 inches high. This is an introduced grass, conunon in every dooryard and about dwellings and cultivated grounds. It maybe found in bloom in the Southern States in almost everj" month in the year. It often forms a considerable ingre- dient in poorly kept lawns, as a result of its spontaneous growth. No. 198. Poa arachnifera Torr. Texas Blue grass. A strong-growing perennial, 1 to 3 feet high, with extensively creeping rootstocks, long leaves, and narrow, densely flowered panicles. This grass is apparently di(cciou8. The pistillate or seed-bearing plants have the spikelets densely woolly, while the male spikelets are smooth. It is a native of Texas, but is now well known in most of the Southern States, where it has been introduced into culti- 62 vation, having been highly recommended as a permanent ]>astnro grass. It may he propagated by seeds or "root cuttings," whieh can be ol)tained from leading seedsmen. It makes its principal growth during the winter months, (-oming into bloom in the latter part of April or early in May. It makes a good sod and withstands well the heat of summer and protracted drought. Owing to the wool liness of the seeds, they are ditlicult to sow, and as they are rather expensive this grass has not l)een so extensively propagated as it otherwise would have been. A somewhat troublesome, but more certain, method of propagation is by root cuttings. These may be planted at any time during the fall or early spring months, being set out in rows 2 feet apart and 6 to 10 inches apart in the rows. The retail price of the seed, according to New York catalogues, is $3 per pound. No. 199. Poa arida Vasey. Bunch Si)ear-gra8s. A smooth, upright jxreunial, 1 to 2 leet high, with rather rigid, sharp-pointed leaves, and a close or narrow panicle 2 to 3 inches long. This grass is a native of the Kocky Mountain region, from the British Possessions southward to Ariziuui. It has short, creeping rootstocks, and although more rigid than many species of I'oa, is one of the most valuable pas- ture grasses of the dry regions of the West. No. 200. Poa buckleyana Nash. Bunch Ked-top. • (Fig. 7.5.) Eather slender, 1 to 2 feet high, with no creeping rootstock, very narrow root leaves, and contracted panicles of usually purplish spikelets. It is a perennial, and a native of the Rocky Mountain regions, growing on the lower foothills and in the valleys. It grows in bunches, not forming a turf, and is regarded by the ranchmen as one of the most valuable "bunch grasses" of the cattle ranges. It has never been introduced into cultivation, but is deserving of attention, for it responds readily to improved conditions, and when growing along streams or in irrigated land makes a luxuriant growth of foliage, and often attains a heio^ht of 2 or 3 feet. There are many species of I'oa native to the northern portion of our country, particularly in the Northwest, and all are tender, nutritious pasture grasses. Wherever grasses grow, from the seashore to tjie highest mountain to]is, from one arctic /one to the other, the genus I'oa has its representatives. No. 201. Poa compressa Linn. Canadian Blue-grass. A slender i)erennial, with much-Hat tened stems, (5 to 20 inches higii, and small, narrow iiauicles. This grass has exti'U- sively creeping rootstocks, and forms a strong turf. It is a native of Knrope,which has become thoroughly naturalized, and is now very widely distributed over our territory. It is closely related to Kentucky Blue-grass, but it is more decidedly blue in color, and is readily dis- tinguished from that species by its strongly ilattened stems, lower habit of growth, and smaller ])aniclc. It is the " Blue-grass" of the farmers of the New Kugland and Middle States. It will grow upon a great varbty of soils, even up(ui t hose so poor and thin as to exclude the growth of other grasses. In culti- vated lands it is likely to become trouljlesome, owing to its creeping rootstocks. There is ]terhai>8 no better pasture grass for dry and poor soils, particularly in the Eastern aneat bogs. The base of the stem is edible, having a taste of mountain cabbage, a species of palm. The introduction of this grass to certain points along our Northern seaboard, where other grasses will not thrive or where there is danger of encroachment upon the laud by the sea, may be desirable. The nutritious qualities of the grass and its furnishing good fodder the year round upon the Falkland Islands has been repeatedly noted by authors. No. 204. Poa flava Linn. False Ked-top. A native of northern Europe and the northern portions of our OAvn country, growing naturally iu wet meadows and along the low banks of streams. It attains the height of 2 to H feet, or even 4 feet in rich, moist soils, and has an expanded, nodding panicle of rather small, purplish, or "bronzed" spikelets. It is found in nearly all parts of New England, and often forms a very considerable and valued portion of the native hay of the low meadows. It has been cultivated to some extent, but should only be used in mixtures, as it does not make a good sod when sown alone. It blooms in July and August. No. 205. Poa nemoralis Linn. Wood Meadow-grass. The larger forms of this are hardly to be distinguished from Foajiaca, and have a similar range. It will, however, grow in a drier soil, excessive moisture being harmful to it. In ^Montana this species ascends to the altiiude of 9,000 feet. At this elevation it is dwarfed in iialjit, but at lower elevations it becomes taller and affords excellent forage. There are several varieties of this grass in the Kocky Mountains and the Northwest, some of them growing upon the dry foot- hills and bench lauds. The larger iV)rms are well adapted ftu- hay. It is less ])roductive than many others, and its cultivation is not recommended, excepting in shady parks or oi)en woodlands where an increase of forage is desired, or in shaded lawns, and then only in the Northern and Middle States. No. 206. Poa uevadensis Vasey. Nevada I)lue-grass. A ])crennial bunch grass from the western i)rairie and plains regions. It grows on both dry and damp soils, produces a large amount of excellent hay, and is apparently worthy of cultivation. No. 207. Poa pratensis Linn. Kentucky Blue-grass. (Fig. 76.) This is apparently native throughout the temperate regions of the northern hemi- sphere. It ranges from Labrador to South Carolina, westward to the Pacific coast and northward to Alaska. In the limestone regions of Kentucky and Tennessee it attains its greatest perfection and is there regarded as the king of 64 pasture orasses. It requires a good soil containing some lime in order to yield profitable crops. It is largely employed in the Eastern and Middle States as a lawn frass. lor which use it is well adapted. It makes a good, firm sod, and is particularly well suited for turfing the slopes of terraces and embankments, where the soil is good. There are several varieties, which difi'er chiefly in the breadth and length of the leaves, particularly those at the base of the stem. It is not so well adapted for the production of hay as it is for pasturage. It should enter into all mixtiires designed for permanent pasture. The slender stems of this grass attord an excellent material for tlie manufacture of the iiner kinds of Leghorn hats. Good and well-cleaned seed should have 95 per cent purity and 50 per cent germinating power. The pow er of germination, how- ever, is usually much below this figure. When used for lawns, sow at the rate of 3 bushels per acre. According to Steb- ler and Schroeter, the seeds should never be covered, but only rolled after sowing, because they germinate better in the light than in darkness. This is the June-grass of the Northern States, Green-grass of rennsylvaiiia, and Smooth-stalked Mead- ow-grass of England. No. 208. Poa subaristata Vasey. Vasey's Sj)ear-gra8S. A iKiciinial, from central Montana, where it is common on dry hills and mountain sh)pes, forming a large percentage of the grass and supplying good pasturage. It is an excellent species for cultivation in Northern pastures. No. 209. Poa trivialis Linn. Ivough-stalked Meadow-grass. An erect perennial, 1 to 3 feet high, with an open, spreading panicle, closely related to Kentucky Blue-grass, from Avhich it diflers in having no conspicuous root- stock and the stem distinctly rough below the panicle. It has been cultivated for many years in England, and is now liighly esteemed as an ingredient in mixtures for permanent pastures. It succeeds best where the climate and soil are rather moist and cool, but is not adapted to sandy soil. In northern Italy this grass is known as the "queen of forage plants," but elsewhere, particularly in tliis country, it is not so highly esteemed, its ])rincipal use being to form bottom grass in jieimanent pastnres. Seed of good (juality should have !I5 per cent purity and 50 per cent germination. When sown alone Ih to 2 bushels of 8;6.j This grass has a wide distribution, being found in the tropical and warmer temperate regions of both the Old and New World. lu New South Wales it is known as Buti'alo-grass, and in Jamaica it is called Pimento-grass. It grows upon every variety of soil, from the apparently sterile sand dunes to heavy clays, but is rarely found far away from the coast. The flattened stems emit ribrous roots at every Joint, where they also readily separate, each piece becoming a new center of growth. The leaves are flat or simply folded, blunt or obtuse at the apex, nearly one-fourth of an inch broad and 4 to 10 inches long. The flowering stems grow to the height of 6 inches to a foot or more. St. Au- gustine-grass grows along our ocean shores as far north as South Carolina, and is extensively used for lawns in Charleston, S. C, and cities in the South near the coast. It is useful for holding sloping embankments, especially those subject to wash. It is jiropagated by cuttings ox sets, and ([uickly covers the most sandy yards with a dense, carpet like growth. In Soutli America the creeping stems are employed iu medicineas a diuretic. This is the Butfalo-grass of Australia, and other local names in this coun- try are Mission-grass and Charleston Lawn- •nass. Fig. 85. — Saccaton (Sporoboliis wrightii). No. 230. Stipa comata Trin. & Kupr. Needle-and-Thread. This is one of the bunch grnsses common in the Rocky Mountain region, growing on the dry mesas and foothills. It is a rather stout, leafy perennial, 1 to 3 feet high, with a panicle usually partly iuclosed in the upi)er leaf sheath; the slen- der awns of the spikelets are 4 to (J inches long and llexuose. This gr.iss h;is some value, affording forage of good ([iKility in the regions where it grows abundantly. In Dakota, Wyoming, etc., it is valued as a hay grass. No. 231. Stipa elegautissinia l.abill. A native of Australia, with erect, branching stems 2 to 3 feet high, narrow lenves, and loose panicles G toH inches long. The axis and long, thread-like branches of the panicle are elegantly plumose with tine, spreading hairs, rendering it highly ornamental. Cultivated in gardens. 71 It ia an elesaiit form of No. 232. Stipa leucotricha Trin. & Enpr. Bearded Mesqnite. Au erect ]>ereiii)ial 1 to 3 feet bigli, with very nnrrow leaves aud a loose pauicle- witli a ft'W loiiff-awDed spikclets. One of the best native hay grasses of oentnil and southern Texas. No. 233. Stipa pemiata Linn. Feather-gra.s8. A native of southern Europe, 1 to 2 feet liigh, growing in dry, open ground, aud often fultivated in gardens as an ornamental, the very long, slender awns being clothed with spreading, silky hairs, presenting a very graceful plume-like appearance. A variety of this grass {Stipa i^ennaia neo-mexicana) grows wild in the mountain regions of western Texas aud Arizona, the species, growing in clumps 6 1o 12 inches in di- ameter, and is deserving the attention of the Hori.st. No. 234. Stipa setigera Presl. Bear-grass. A native of California, extending northward to Oregon and eastward through New Mexico and Arizona to Texas. It is common on the coast ranges and on the foothills of the Sierra Nevada, where it is re. garded as one of the most valuable of the native bunch gras.ses. No. 235. Stipa spartea Trin. Torcnpine-grass. Rather stout, 18 inches to 3 feet high, with long leaves and few-flowered panicles. The stout and twisted awns are 3 to 6 inches long, and at the base of the tloweriug glume is a long aud very sharp- pointed callus. When mature, the awned llowering glumes soon fall off, leaving the large, pale, straw- colored, |)ersistent empty glumes, which impart to the panicle a characteristic oat-like appearance. The awns, when dry, are bent and very strongly twisted, but when moistened they gradually untwist, a character which enables the seeds to bury them- selves in the ground, this being possible on account of the very sharp callus at the base of the fruiting srlume. The same character also rendci's the seeds of this grass dangerous to sheep, as they readily become attached to the wool, and may penetrate the tlesh of the animal, causing serious injur}-. Aside from this danger of affecting the quality of the wool, and possibly the life of the sheep, this grass may be considered a good forage plant, as it makes a very good hay, although somewhat coarse. It is particularly common in ihe prairie regions of Iowa, Nebraska, South Dakota, aud Minnesota, extending westward to the Rocky Mountains, where it frequently occurs upon the dry foothills and bench lands. This is the Bntfalo-grass of the Saskatchewan region. In some localities it is known as Needle-grass, but that name is reserved for Jrisiida fasciciilata. It is also known as "wild oats" in North Dakota. No. 236. Stipa tenacissima Linn. Esparto. A native of the sandy regions of southwestern Europe and northern Africa. It is a tall perennial, with long, stiff, and very tough leaves, from which ropes, baskets, mats, hats, and other articles are woven. The leaves are employed largely in England and this country in the manufacture of paper, for which purpose this grass is superior to straw. It is one of the most important articles of export from Algeria, and from northern Africa and .'^pain more than 2,000 tons of Esparto are exported to Great Britain annually. " Ten tons of dry Esparto, worth from $18 to $25 per ton, can be obtained from an acre under favorable circumstances.'* Fig. 86.— St. Augustine-grasa ( Stenotaphrvm dimidiat'u.m) . 72 The grass will grow on almost auy kiud of soil, from that whith is poor and sandy or gravelly to heavy calcareous and clayey soils. It thrives in the dry and hot climates of northern Africa, where many millious of acres are covered almost exclusively with it. This grass is extensively cultivated in the south of France, and possihly its introduction into some of our Southwestern districts may render proritaldc. regions now practically worthless. It may lie propagated Ijy seeds or hy divisions of the root. The latter is the more common method. This and Lygeum apartiun ((institute the Esparto of commerce. No. 237. Stipa vaseyi Scribn. Sleepy-grass. A sttmt hunch-grass 3 to 5 feet high, which grows in the Rocky Mountains at an altitude of Irom 5,000 to 6,000 feet, 'ihis grass, although producing a large bulk of stems and leaves, is regarded with suspicion bj' stockmen. It is said that when this grass is eaten in a fresh state by horses it has a narcotic or jioisonous effect, causing the animals to become crazed or "locoed,'' its action thus resembling that of the diadly loco weed {Astragalus moUlssimits). Hay made from this grass does not appar- ently possess any poisonous qualities. No. 238. Stipa viridula Triu. Feather Bunch- grass. (Fig, 87.) A rather slender grass, 1 to 3 feet high, growing in the Kocky Mountain legion and on the foothills and mesas, from British Columbia southward to Mexico and westward to the coast On good laud, under irrigation, this gra.ss attains the height of 3 feet or more, and is by far the most valuable of the Stipas for hay. The leafy culms are terminated by a narrow, many-Howercd panicle of compar- atively small and rather short-awued spike- lets. The seed may be easily gathered. The callus at the base of the fruiting glume is short and l)arely pointed and not produced into a long, very sharp, spur-like extension, as in Porcupine-grass. Nc. 239. Thuarea sarmentosa Pers. A low, extensively creeping grass, rooting at thi^ joints, with ascending llowering branches, short leaves, and slender spikes about an inch Icmg. A native of Ceylon, northern Australia, etc., growing on the sands of th(! coast. It is a tender grass, and may be useful in binding coast sands in tropical countries or in the formation of lawns. No. 240. Trichloris blauchar(iiana Scribn. A jieronnial, li to 3 feet high, with flat leaves, and six to eighteen slender, Itearded sj)ikes, vrhicli are 2 to 5 inches long, digitate or fasciculate at the apex of the culm. It has long l»eeu kuowu to llorists under the name of Chhropsix hlainh- ardiaiia, and is estceme(l as an ornamental grass, its attractive appearance mak- ing it worthy of attention. It grows in Arizona and Mexico, extending into South America. No. 241. Tricholaena rosea Nccs. A South African annual ( ?), with ditTueely brandling stems 2 to 1 feet high. The spikclcts are in loose i)ani( b s. and clothed with reddish, silky hairs. It pre- FiG. 87.— Fcatlier Buncb-grass (^tipa viridula). 73 sents a pleasiug appearance wheu iu llower, and the panicles are valued for dry bouquets. It has recently received some attention by agriculturists on account of its very vigorous rapid growth and productiveness. Experiments made iu this country and elsewhere indicate that it possesses much value as a meadow or hay grass in mild climates. Three hundred stems have been counted on a single plant. These stems take root wherever they touch the ground, and an acre has been calculated to yield 30 tons of green fodder iu the rich valleys of the Macleay River, New South "Wales. It is easily propagated by seed. No. 242. Triodia exigua Kirk. A little alpine grass, endemic in New Zealand. It forms even plots of turf, often many square yards in extent; the leaves are firm, short, and shining; the com- pact growth of tbe turf or sward prevents the encroach- ment of other grasses or weeds. It is particularly to be recommended for croquet lawns, never reiiuiring mowing (K:rk). In the mountain regions of the West are sev- eral of these small turf-forming grasses, which would, if cultivated, make excellent carpet-like lawns in the region of the Northern and Middle States. No. 243. Triodia seslerioides (Michx.) Benth. Fall Red- tt. Augustine-grass, and may prove superior to that for lawns in the Southern and Gulf States. The habit of growth of Japanese lawn-grass is very similar to that of Bermuda, but the cree])ing stems are rather stouter and more rigid and the upright branches or tufts of liowering stems are never 80 tall, rarely exceeding (3 inches. It may be propagated by root cuttings or by seed. Importations ot both roots and seeds from Korea have been successfully grown here, and the grass has ])roved hardy as far north as Connecticut. The leaves turn brown in the autumn, as do those of Bermuda. Fig. 91. — Japane.se Lawn-grass (Zoysia pungem) ; a to d details of tbe spikelet. GRASSES FOR SPECIAL SOILS OR USES.

Department of Agriculture, Division of Agrostology, Washington^ D. C.^ February 26, 1900. Sir: Owing to a continued demand for copies of Bulletin No. 14 of this Division, entitled "Economic Grasses," after the first edition was exhausted, I have revised the matter contained therein and have the honor to request the printing of a new edition of same. This bul- letin embraces brief descriptions of the more important economic grasses of this country, or those which have been introduced because possessing some merit, and it is believed ailords a ready answer to the usual inquiries respecting a large number of our grasses. Much of the matter here presented is taken from Bulletin No. 3 of this Division, but owing to the fact that that bulletin exceeded 100 pages the edition pu])lishcd was limited to 1,000 copies, and consequentl}' was very quickly exhausted. Respectfully, F. Lamson-Scribnek, A(j7^ostologist. Hon. James Wilson, Secretary of Agriculture. CONTENTS. Page.

A fibrous-rooted, rather slender, upright perennial, 2 to 3 feet high, with bearded, nodding heads or spikes resembling sleuder heads of wheat. This grass is more or less frequent in the northern parts of the United States, ranging from Maine westward to the Dakotas. Bearded Wheat-grass is closely related to the more common and better known Couch-grass (A. repens), but differs markedly from that species in having no creeping rootstocks, and in the longer beards or uwns to the spikelets. No attempts have been made to introduce this grass into gen- eral cultivation, but its habit of growth and other characters indicate that it may possess considerable agricultural value. It is readily propagated by seeds, which- may be easily gathered. No. 2. Agropyron divergens Nees. Wire Bunch-grass. A slender, usually densely tufted perennial, 1 to 2 feet high or more, with very nar- row, spreading leaves, and bearded or beardless spikes. The beards or awns, when present, are widely spreading or divergent. This grass is common in the Eocky Mountain and Pacific Slope regions, extending westward to the coast. On rich lands it often grows to the height of 3 feet, but upon the dry bench lauds it rarely exceeds a foot or 18 inches in height. On dry lands the stems become wiry with age, and are avoided by stock; but the grass is considered valuable by the ranchmen for winter grazing. Samples of this grass received from some points in the West, particularly from Washington, indicate that it possesses much agricultural value when grown upon good soil, and as it will thrive in the semiarid regions of the Northwest, its cultivation may prove desirable,, Propagated readily by seed, which can be easily gathered. No. 3. Agropyron pseudorepens Scribn. & Smith. Western Couch-grass. A perennial, with creeping rootstocks, abundant in the northern prairie States, pro- ducing tall and leafy stems, which resemble those of Couch-grass, but are less wiry. This is less plentiful in the semiarid belt than the Western Wheat-grass or Colorado Blue-stem, but is better adapted for cultivation as a hay grass because of its softer stems and leaves. It is one of the most promising native species. No. 4. Agropyron repens (L.) Beauv. Couch-grass. (Fig. 1.) A grass abundant everywhere in the Eastern and Middle States, growing in the open fields, and in mauy places it has become one of the worst of Aveeds. Ofteu the chief labor in managing hoed crops consists in subduing this pest. When once established, it is hardly less difficult to eradicate than the well-known .Johnson- grass of the Southern States. It is, however, a valuable hay grass, and for two or three years the yield is large, but, like the Western Blue-stem, it "binds itself out," and the sod requires breaking in order to -restore the yield. It is an 7 8 excellent grass for bindiug railroad and other embankments subject to wash, and can be recommeudetl for this purpose. The roots are well known in medicine under the name of iiafZi\r i 1 ,.7 the Middle States. Fig. 3.— Water Foxtail (Alopecnnts genieulatus). No. 16. Alopecurus occidentalis 8cribn. Mountain Foxtail. A grass of the mountain meadows of the Rocky Mountains, growing in rich soil along streams and in the open parks. It lias slender, erect stems 2 to 3 feet high, with short, oblong heads, thicker and shorter than those of common Meadow Foxtail. This grass is occasionally found covering extensive areas to the exclusion of other s])ecies. It yields a large bulk of tine, long, bright- colored hay, which is highly valued where it can bo obtained. For the more elevated meadows of the Rocky Mountain region, and doubtless also for the New Knglaud and North Midfllo States, this grass would form an excellent addition to the cultivated species, and its introduction is recommended. No. 17. Alopecurus pratensis Linn. Meadow Foxtail. (Fig. 4.) This well-known European grass has been introduced into this country and culti- vated to some extent in the New England and Middle States. It is a valuable grass for moist meadows and pastures, particularly the latter, on account of its Bui. 14, Div. of Agrostology. Plate i. Fig. 1.- Planting Beach Grass in Sand near Provincetown. Mass. Fig. 2.— Kafir Corn in Grass Garden of the U. S. Department of Agriculture. 11 early growth, being one of the earliest of the cnltivated grasses. It is very hardy, and on good soil yields a large amount of excellent forage. In Europe it is regarded as one of the best perennial pasture grasses. It should enter into all mixtures for permanent pastures, because it is very last- ing, highly nutritious, and earlier than most other species. This grass has a record of producing 20,418 pounds per acre of green grass, 6,125 pounds of hay, and 8,167 pounds of aftermath. It is never sown by itself, but is always mixed with other grasses and forage jjlants, because it gives a full yield only in the second or third year. Average number of seeds in a pound, 907,000. Price of seed quoted in New York catalogues, $2.30 per bushel, or $32 per 100 pounds. No. 18. Animophila arenaria (Linn.) Link. Beach-grass. (Fig. 5.) This grass grows more or less abundantly along tiie sandy coasts of the Atlantic and the shores of the Great Lakes. It has strong, creeping rootstocks, upright stems 2 to 4 feet high, and long, rather rigid leaves. The narrow, densely flowered panicles which terminate the stems are from 3 to 10 inches long. It is one of the most valuable grasses adapted to binding the drifting sands of our coasts, and has been culti- vated for this purpose in this as well as in other countries. The action of this grass in hold- ing the drifting sands is like that of brush or bushes cut and laid upon the ground in accu- mulating snow when drifted by the wind. The sand collects around the clumps of grass, and as it accu- mulates, the grass grows up and overtops it, and will so continue to grow, no matter how high the sand hill may rise. This process goes on over the whole surface of the plantation, and thus many acres may be raised far above theirorigiual level. A plant will, by gradual growth upwards, finally form stems and roots sanded in to the depth of fully 100 feet. Beach-grass is best propagated l)y transplanting (PI. I, fig. 1). The grass is pulled by hand and planted 1 to 2 feet apart, according to the slope, by forcing a long spade or shovel into the sand, which is then carried forward, making an opening into which the roots are thrust, the spade then being withdrawn and the sand pressed close about them. The planting may be done either in the spring or fall, i:»referably in the fall. When projia- gation is by seed, the sowing should bo done early in the spring and brush laid over the ground for holding the sand and seed temporarily in place. Beach- grass has been used for the manufacture of coarse paper, and it makes an excel- lent and very durable thatch. It is of no value for fodder. FiQ. 4.— Meadow Fox- tail (Alopecurus pra- tensis).

A stout, leafy perennial, 1 to 3 feet high, aftording excellent grazing when young, but the mature seeds are much dreaded by sheep owners, as by their peculiar structure tbey not only become attached to and injure the wool, but ofteu pene- trate the skin and even the intestines of these animals. The strong rhizomes and tough fibrous roots which this grass has, commend it as a soil binder for river lianks, dams, etc. The awns indicate by their twisting the amount of moisture in the air, and may be used as rain or fair weather indicators. In India this grass is used for thatching. It is a native of tropical and subtropical regions of both liemispheres, extending northward into we.stt'rn Texas, New Mexico, and Arizona. No. 20. Andropogon glonieratus (Walt.j B. S. r. Brook-grass. A stout perennial, 2 to 4 feet high, with dense, more or less elon- ^^: Fig. 6. — Johnson-gras-s {Andropogon hale- Fig. 7. — Bushy Hlue-stem (Andropogon nutans) : a to/, pensis). details of the spikelet. gated, broom-like panicles. It grows in low grounds and marshes from southern New York to Florida, also occurring in Mexico and Lower California. This species is esteemed a valuable pasture grass in the .South. Its stems and leaves when young, are tenal grain of such nortliern countries as Norway and Sweden, and Scotland, and in these countries boiled oatmeal and oatmeal cakes are impor- tant articles of food. Boiled oatmeal is also much used in this country, espe- cially at breakfast. The grain, however, is principally cultivated here as food for horses. In the Southern States, oats, particularly winter oats, are largely grown for forage. Sown in August, they furnish the best grazing from Octo- ber to the latter part of April, and will then yield a more certain and a larger crop of grain than spring-sown oats. They are often cut green for soiling and for hay. Oat hay is quite extensively used in the South and in California. The practice is to cut when the grain is in the "dough" stage, or when the straw commences to turn yellow below the head and the leaves are still green. The yield ranges from 3 to 4i tons ]ier acre, according to the variety and the season. The feeding value of oat hay is higher than that of timothy, containing about 8.8 percent of crude protein, and 55 to 65 percent of fat formers, while the latter (timothy) contains from 5 to 7 per cent crude protein, and 45 to 55 per cent fat former.s. Among the cereals, oats are the most nutritious, but oaten flour lacks the gluten of wheat, rendering the making of bread from it impossible. Oatmeal is richer in nitrogenous matter than soft wheats, and contains more fat than any of the other grains. Russian " quas" beer is made from oats. No. 42. Aveua sterilis L. Auimated Oats. A stout, oat-like grass, with one-sided panicles, and very large, awnedspikelets ; the awn is very long, twisted, and "kneed" or geniculate. It is the twisting and untwisting of these awns when exposed to changes of moisture and dryness that has given to this grass the common name of "animated oats." The untwisting or coiling-ui> of the awn causes the spikelcts to tumble about iu various directions, suggestive of independent motion or life-like activity. No. 43. Bambusa. Bamboo. The bamboos belong to the Bambusew, a tribe of grasses numbering about 175 species, chiefly limited to South America, southern and eastern Asia, and the East Indies. There are no European species, and only two in North America (see Arundmaria). Of the whole number of species only one is common to both hemispheres. The largest bamboos attain a height of 120 feet, with a diameter of a foot or more. A Soutb American species has leaves 3 to 12 inches wide and 5 to 15 feet long. In India are extensive bamboo forests, and in countries where these grasses abound they are employed for many purposes. They furnish material for the complete construction and furnishing (including domestic utensils) of houses. They are used in shipbuilding and in the construction of bridges. Buckets, ])itcher8, flasks, and cups are made from sections of the stems. Baskets, l)oxe8, fans, hats, and jackets are made from split l)amboo. Ropes and Chinese paper are made from these grasses. A Chinese umbrella consists of bamboo paper, with a bamboo handle and split bamboo for a frame. The leaves are used for packing, filling beds, etc., and occasionally servo as fodder for stock. The young shoots serve as a vegetable. Tabashir, or bamboo manna, a silicious and crystalline substance which occurs in the hollow stems of some bamboos, is regarded as jiossessing jnedicinal properties. Good drinking water collects in quantities in the hollows of the intornodes of nuiny of the; bnger bamboos. All sorts of agricultural implements, appliances for spinning cotton and wool or for reeling silk, are often constructed entirely from bamboo. Very many articles of household use or decoration made from bamboo have become articles of com mcrco in Europe and this country. So numy and varied are the uses of the several species of bamboo, that it is possible to mention litre only a small part of them. B;imbooH .-ire ]>ropagated by seed, but more often b.\' cuttings. I'lante from the seed do not attain a sufficient growth to admit cropping under 10 or 12 years. 21 No. 44. Beckmannia eriicaeformis (L.) Host. Slough-grass. (Fig. 16.) A stout, erect, subaquatic perennial, 1 to 4 feet high, with narrow, densely flowered panicles. The leaves are broad and flat, and the stems are coarse but tender, becoming somewhat woody when old. It grows along the banks of streams and rivers and frequently follows the course of the irrigating ditches. When young, however, this grass is palatable and readily eaten by stock. In some portions of the North- west, to which region this grass is confined in this country, it often occurs in such quantities as to constitute an import- ant part of the forage of low pasture lands. It may be recog- nized by the peculiar, spike-like branches of the panicle, which have some resemblance to the rattles of a rattle- snake, and for this reason it is sometimes called " Rattle- snake-grass." It-is deserving of trial under cultivation for low meadow lands in the more Northern States, and is especially adapted to irrigated alkaline lands. No. 45. Bouteloua curtipeudula (Ms.) Torr. Side Oats. (Fig. 17.) This is among the tallest of our species of Bouteloua, the rather stout, tufted stems being from 1 to 3 feet high. It has tough, perennial, fibrous roots, flat, long-pointed leaves, and many short spikes arranged along tlie upper portion of the stem. Its range extends from New Jersey westward to the Rocky Mountains and south- ward through Texas into Mexico. Where abundant, it is said to make fair hay, and the numerous root leaves afi'ord good pastur- age. The hay is readily eaten by stock, but on the range cattle show a decided preference for Blue Grama. Several species of Grama have been successfully grown in small cultures at some of the experiment stations, but none of them, although apparently most valuable as pasture grasses for the semiarid regions, have been introduced into general cultivation. No. 46. Bouteloua eriopoda Torr. Black Grama. This is one of the species of Grama so valuable for grazing in New Mexico and Texas. The slender stems are 1 to 2 feet high, and from its thrifty habit of growth it forms dense and excellent pasturage wherever it grows abundantly. It is a common grass along the Rio Grande and in the region between the Pecos and the Gila; also in the Olympia, Guadalupe, and Eagle mountains, and on the Staked Plains in Texas. The woolly-jointed stems at once serve to distinguish this from the allied species of Bouteloua. Fig. 16.— Slough-grass {Beckmannia erucce- formis). Fig. 17. — Side Oats (Boute loua curtipendula) . Blue, or No. 47. Bouteloua oligostachya (Nutt.) Torr. White Grama. (Fig. 18.) This is one of the most abundant and most valued of the Grama grasses, and extends from Wisconsin we.stward to California, and southward into Texas and northern Mexico. It is a perennial, 6 to 18 inches high, its strong rhizomes and numerous 22 root-leaves forming dense and more or less extensive patches of excellent tnrf. In Montana it is known as Buffalo-grass. It frequents the bench lands of that State, growing at elevations of from 3,000 to 4,000 or 5,000 feet, and not infre- quently covers wide areas. No other grass better withstands the tramping of stock, and it is unsurpassed for grazing purposes. In the early days in the Southwest it formed a large proportion of the hay delivered at the various mili- tary posts and stage stations, and was considered the best ol)tainable there. Like the true Buffalo-grass, it cures during the dry season in the turf into perfect hay, losing none of its nutritious properties. No. 48. Bouteloua polystachya Torr. Low Grama. This is a small, slender grass, of good quality. It is one of the smallest of the Gramas, and only occurs sparingly here and there in scattered tufts. It rarely exceeds 6 inches in height, and is confined to the arid regions of the Southwest. No. 49. Bouteloua repens (HBK.) Scribn. Creep- ing Grama. A common grass in the vicinity of Acapulco, Mexico, where, according to Dr. E. Palmer, it occurs on the highest mountains aud down their stony slopes to the water's edge. Greedily eaten by stock. No. 50. Bouteloua texana Watson. (Seed Mesquit.) This is a small but excellent grass, common about San Antonio and at other points in. Texas, chiefly along the Rio Grande. It is recognized as an important grass in the stock ranges. No. 51. Brachypodium japouicum Miq. Japanese Wheat-grass. A promising Japanese perennial, closely resembling Bearded Wheat-grass (Agropyron caninum), but of rather stronger growth. It was introduced into California by the Agricultural Experiment Station of the Uuiveisity of California, at Berkeley, from New Zealand, in 1886, and the first seed was dis- tributed in California in 1889. It has been culti- vated with success at a number of points iu Cali- fornia and at several of the experiment staf ions in the East. In the Southern States it is regarded as a valuable grass for winter grazing, as it makes its best growth during the cooler months. Small Quaking-grass. (Fig. 19.) An erect perennial, from 1 to 2 feet high, introduced into this country from Europe because of its pleasing oniamoutal aitpearanee. It has escaped from cultivation in many places, and has become sparingly naturalized. It is occasionally culti- vated for ornament; the nodding panicles of rather showy spikelets arc used for winter bonciuets. It is but little known here, but is classed as a valuable meadow grass in Middle Eurojte and is recommended as an admixture for pas- tures on dry, thin soils. liriza minor is a smaller and more delicate annual species, also cnltivated occasionally as an ornamental and for dry boui|uet8. liriza viarima, also an annual, is a larger ornamental species. No. 53. Bromus ciliatus l,inn. Swamp Chess. A native perennial of wide range, frequent in ojxmi woodlands, growing to the height of 3 to 5 feet. It is leafy to the toj). and would doubtless make a hay grass of Fig. 18. — Blue, or White Grama {Bouteloua oligostachya) . No. 52. Briza media Linn.

It makes a vigorous early growth on good soils and is recommended for propagation in wooded parks and woodland pastures. No. 54. Bromus inermis Leyss. Smooth Brome-grass. (Fig. 20.) An erect perennial, 2 to 5 feet high, with strong creeping rootstocks, and a loose open panicle, 4 to 6 inches long. A native of Europe introduced into this country by the Agricultural Experiment Station of the University of California about 1880, which gives considerable promise of value both for haj^ and pasturage. It is strongly stolon if erous, and quickly makes a thick, firm turf. It appears to grow with equal vigor in Canada and in Tennessee, remaining green through- out the winter season in the latter State. The strong perennial character of Fig. 19. — Small Quaking-grass (Briza media). Fig. 20. — Smooth Brome-grass (Bromus inerm^is) . this Brome-grass and its unusual drought-resisting powers are qualities which recommend it for general cultivation, particularly in the semiarid regions of the West and Northwest. It thrives well on dry, loose soil, but of course the better the soil the greater the yield. Its nutritive value is comparatively low, and before undertaking its cultivation the fact should be remembered that it is somewhat difiQcult to eradicate when once established, although by no means so difiScult as Couch-grass or Johnson-grass. In Europe it is classed among the best hay grasses. The seeds are quoted in New York catalogues at from $20 to $22 per 100 xjounds. A bushel weighs about 14 pounds. Sow two bushels to the acre if sown alone. In this country the yield of seed per acre has been 600 pounds, which at the prices named would make it a very jirofitable crop. Pro- fessor Fletcher, of Canada, reports a yield of 3f tons of hay per acre. 24 No. 55. Bromus pumpellianus Scribn. Western Brome-grass. A native of the Northwestern .states in the Rocky Mountain region, extending into Canada. In habit of growth it closely resembles Hungarian, or Smooth Brome- grass (B. inermis), and is doubtless equally valuable. Prof. James Fletcher, who has cultivated this grass at the experiment station at Ottawa, Canada, says, "This is a very valuable grass, producing an abundance of leaves, continuing in llower for a long time, and giving a heavy aftermath." No. 56. Bromus racemosus Linn. Upright Chess. An introduced annual, 1 to 3 feet high, with more or less spreading and nodding panicles and smooth spikelets. This is a very common grass in cultivated fields and waste places, and is often mistaken for Chess, from which it differs chiefly in its narrower panicles and straight awns, which are nearly as long as the Fig. 21.— Chess {Bromus secalinus). no. 22.— Rescue- grass {Bromus unioloides). flowering glumes. This grass has booorae very common in certain sections, par- ticularly in the South. A field of it presents an attractive appearance, and the hay produced is of good quality. No. 57. Bromus secalinus Linn. Chess; Cheat. (Fig. 21.) A well-known, weedy, annual grass, introduced into this ccmntry many years ago, and now coniinon in grain fields and waste lands. The panicle is spreading and more or less drooping, and the awns of the flowering glumes are usually much shorter than the glumes thciniselves and nioie or less flexuose. The idea that Cheat or Chess is degenerated wheat has no foundation whatever in fact. Only Cheat seeds will produce Cheat, and it is certain that wherever these plants appear they were preceded by Cheat seeds, which may have been introduced with the grail) sown, <.r brought by birds or animals from other fields. Cheat and wheat are only remotely related; they Welong to (luite distinct tribes in the grass 25 FiQ. 23.— Bnffalo-^rasa (Bui- bilisdactyloideg). a, female plant; b, male plant. family; wheat is less likely to change into cheat in a single generation than into the more nearly allied oats, or than -wheat is to change into barley, with which it is very closely related. No. 58. Bromus unioloides Willd. Eescue-grass. (Fig. 22.) This Bromu8, which is a native of South America, and probably also of the extreme southwestern portion of the United States, is a strong-growing grass, with rather broad, much flattened, usually bearded spil^elets. It grows to the height of 1 to 3 feet, and in the more vigorous plants the branches of the nodding panicle are widely spreading. It grows rapidly, seeds freely, and dies after seeding. If, by frequent mowing or close grazing, it is prevented from going to seed, its duration may be continued over two or three years or more. If the seeds are allowed to fall, as they frequently do when mature, young plants soon appear, and a fairly continuous growth of this grass may thus be maintained. In many parts of the Southern States, where it has been most cultivated, it has come to be regarded as one of the best winter grasses, as it makes its chief growth during the cooler months of the year. Sow in August or September, at the rate of 30 to 40 pounds to the acre. No. 59 Bulbilis dactyloides (Nutt.) Eafin. Buffalo- grass. (Fig. 23.) This is the true Buffalo-grass of the Great Plains region, which is reported to have been much more abundant and more widely distributed in times past than It is at present. Now, however, it is known to extend from the British Possessions southward into Texas, where it is considered an invalu- able grass and one of the best constituents of sheep pastures. It has a low habit of growth, rarely more than 5 or 6 inches high, and pro- duces numerous creeping and widely spreading branches or stolons, which root at the joints, each joint forming a new tuft, and in this way the grass often covers large areas with a close mat of fine-leafed herbage, which is greatly relisshed by all grazing animals. As a winter for- age, it is without an equal. The habit of growth of this plant is very similar to that of Bermuda-grass, but the stems and leaves are much finer and the turf formed more compact. Live roots transplanted from Nebraska to the grounds of the Department of Agriculture at Washing- ton, D. C, have grown with remarkable vigor, and it may be possible to utilize this most palatable and nutritious grass in portions of the Ea^ern or Southern States. No. 60. Calamagrostis canadensis (Michx.) Beauv. Blue- joint. (Fig. 24.) A native grass common in the Northern and Northwestern States, extending clear across the continent, usually Fig. 24.— Blue-joint (CaJ- growing in moist meadows. The leafy stems are 3 to 5 amagroitis canadensis). feet high, and the open brown or purplish panicles have some resemblance to those of Redtop. Occasionally it is found occupying considerable areas to the exclusion of other grasses, and under such conditions it yields a large amount of excellent hay, highly prized by farm- ers and eaten with avidity by all farm stock. This grass grows naturally on low, moist meadows, and has succeeded well under cultivation. In the northern por- tion of the United States its more extended culture for hay is recommended. 26 No. 61. Calamagrostis cinnoides (Mulil.) Spreug. Reed. Bent- grass. A stout, reed-like grass, 3 to 5 feet bigli, not infrequent in low, moist grounds and swamps, ranging from New England southward to Tennessee. No attempts have been made to cultivate it, and little is known of its agricultural value. Probably of some use for low woodlands where grasses are desired for pasturage, and if it will thrive in the open it would make a most excellent bay-grass for low meadows. No. 62. Calamagrostis hyperborea amerioana (Vasey) Kearn. Yellow-top. A very common grass in low meadows and shady river banks throughout the North- west. It affords a large amount of excellent hay if cut iu proper season. A good grass for cultivation in moist, sandy meadows. No. 63. Calamagrostis neglecta(Ehrb.)Gaertn. Pony- A rather slender, erect jierennial, with narrow leaves, and a contracted, densely flowered, brownish panicle, 3 to 6 inches long. A native of Northern Europe and North America, ranging along our northern borders from Newfoundland and Maine to the Pacific, being most abundant in tbe Eocky Mouutain region. Under experimental cultivation it has succeeded well. It is a productive grass, much liked by stock, especially horses, and is deserving a place among the cultivated species. No. 64. Calamagrostis suksdorfii Seribn. Pine-grass. A rather slender, erect grass, 2 to 3 feet high, with smooth stems, narrow leaves, and contracted, usually pale, straw-colored panicles. A common grass in the Northwest, growing in low pine woods or on moist mountain slopes. It is said to be one of the most common grasses in Washington, and it presents all the qualities of an excellent hay or pasture grass. No. 65. Calamovilfa longifolia (Hook) Seribn. Sand- grass. (Fig. 25.) A stout, long-leafed grass, 1 to 4 feet high, growing in sands or sandy soil along the shores of the Great Lakes and in the Missouri region of the West, ex- tending southward to Kansas. Its very strong and far-reaching rhizomes or creeping "roots" make this an exceedingly valuable grass for binding drifting sands, or those subject to Avasli by swift currents or As a sand binder for interior regions of the country Fig. 25. — Sand-grass (Oalamo- vilfa longifolia). the beating of the waves Its long, tough leaves suggest a possible this grass is probably unsurpassed value for paper making. No. 66. Campulosus aromaticus (Walt.) Seribn. Toothache-grass. (Fig. 2fi.) A perennial grass with erect stems 3 to 4 feet high. Native of the Southern States from Virginia southward, growing iu the wet pine barrens, possessing no agri- cultural value, but rather curious iu appearance. The strong rootstocks are lemon-scented and have a pungent taste. No. 67. Cenchrus echinatus Linn. Cock-spur. A rather stcmt annual, with branching culms 1 1o 2 feet long, and dense heads or spikes made up of 20 or more globular, spiny burs containing the spikelets. It is a weed of the fiehls and waste places of the Southern and Southwestern States. 27 No. 68. Cenchrus tribuloides Linn. Sand-bnr. (Fig. 27.) A widely distributed grass growing in sandy soils along river hanks, the seashore and more or less scattered throughout the interior of the country in sandy dis- tricts. It is one of the worst of annual weeds wherever it becomes abundant. The prostrate branching stems are 1 to 2 feet long ; the spikes are composed of 10 to 15 strongly spiny burs, which readily become detached and adhere to passing objects. No pains should be spared in efforts to exterminate this grass wherever it makes its appearance. No. 69. Chaetochloa glauca (Linn.) Scribn. Yellow Foxtail. (Fig. 28.)

It is especially common in the Southern States, where it continues to bloom throughout the season, from June to Octo- ber. It is distinguished from Setaria vb'idis by its somewhat larger spikelets and more widely spreading yellowish bristles. No. 70. Chaetochloa italica (Linn.) Scribn. Millet; Hungarian-grass. (Fig. 30.) This grass, in some of its varieties, has been cultivated in the East for many centu- ries, and in some parts of India and Trans-Caucasia it still forms an important article of food. Its culture extends back to an early date in Egypt, and in the lake dwellings of the stone age it is found in such quantities that it must be regarded as tbc main bread supjily of the prehistoric peoples (Hackel). In Europe and in this country it is cultivated to some extent for fodder and for the 28 seed, the latter being used chiefly for fowls. It grows rapidly, and may be cut within sixty or sixty-five days from the time of sowing. If used (or fodder, it should becut just as it. begins to head, before blooming, for when more advanced it is apt to be injurious to stock fed upon it. When cut in good season it is one of the most valuable of soiling plants. German Millet (fig. 29) is only a vaiiety of ChcetocMoa italica, distinguished by its smaller, more compact, and erect heads, the bristles of which are usually purplish. Sow 2 to 3 pecks per acre for hay. One peek is sufficient when sown for seed. No. 71. Chaetochloamagna (Griesb.) Scribn. Giant Millet. (PI. II.) This native millet grows in swamps along the coast from Florida to Delaware, The leaves are very broad and long, and the stems are often 8 or 10 feet in height. It is one of the most promising grasses for use in the reclamation of swampy Fig. 29.— German Millet. Fig. 30.— Millet (Okcetochloa italica). lands along the coast. It has been grown successfully in the grass garden on the Department grounds. A single plant, with much branched stems, is shown in PI. IT. No. 72. Cliaetochloa verticillata (Linn.) Scribn. Bristly Foxtail. Has about the same wide distribution as ChatocMoa glauca, but is much less com- mon in the United States. It is rarely found except in waste town lots and about dwellings in the Atlantic States. The bristles in this species are barbed downward, on account of which the "heads" cling to clothing or other objects with which they may come in contact. A weed. No. 73. Chaetochloa viridis (Linn.)

No. 94. Elymus mollis Trin. Soft Sea Lyme-grass. A grass which closely resembles and has the same habit of growth as Elymus arenarius. It is distinguished by having the stem soft-downy just be- low the head or spike and in having five to seven flowered spikelets, the outer glumes of which are broader and five- to seven-nerved. This grass occurs along the shores of the Great Lakes and northward on both the Atlantic and Pacific coasts. No. 95. Elymus triticoides Xutt. Wild Wheat. By some this has been regarded as a small, reduced form of lilymiis condensatus, mentioned above. It grows to the height of 2 to 3 or 4 feet and is native of the Rocky Moun- tain region and Pacific Slope, extending eastward nearly to the Mississippi. While it is a grass of good appear- ance and possibly of some agricultural value, no attempts have been made to cultivate it. No. 96. Elymus virginicus Linn. Terrell-grass. (Fig. 40.) The most common of our native species of Lyme-grass, growing along streams, the borders of woods and thick- ets, more rarely in the open ground. It is an erect, smooth grass, 2 to 3 feet high, with rigid terminal spikes, which are often partly included within the upper leaf- sheath. This grass has the appearance of possessing some agricultural value; it forms an inferior turf, and by the time it blooms all the lower leaves are usually dead. When young it doubtless possesses some value as a native pasture grass. In Kansas, South Dakota, and Nebraska it is regarded a valuable grass for wood- land pastures. Fig. 39. — Sea Lyme- grass (Elyinvs are- nariut). Fifi. 40. — Terrell-grass (Elyrnus virginicux). 36 No. 97. Epicampes rigens Benth. Dcor-grass. (Fig. 41.) A stout, erect grass, 3 to 4 feet bigh, with rigid, wiry stems, aud a very long, narrow, densely llowered, spike-like panicle. This grass is not nncommon in Arizona, southern California, and New Mexico, growing in sandy soil. It is regarded as one of the best native dry land grasses, and is clo.sely grazed wherever stock can get at it. The roots of Epi- campes macronra — Mexican Broom-root or Mexican Whisk — are used in making brushes and are exported from Vera Cruz to Europe for this purpose. No. 98. Eragrostis abyssinica Link. Teff. A branching, leafy annual, 2 to 4 feet high, with widely spreading capillary panicles of many spikelets. This grass grows readily from seed, which is produced abnnd antly, and it may be of some value for hay in parts of the South or Southwest. In northeastern Africa, where the grass is apparently native, the grain is extensively used for food, being made into bread, which possesses a slight but agreeable acid taste. There are two va- rieties ci;ltivated, a white aud a red variety, the for- mer being much superior to the latter and used only by the higher classes. It is sometimes grown in gar- dens for the elegant pani- cles, which are nsed in bouciuets. Era to 18 inches high, with narrow, flat leaves and capil- FiG. 41.— Deer-grass {Epi- campes rigens).

In this country it has received no attention or is regarded as little more than a ^^eed, but in Australia and India il is spoken of as being an excellent fodder grass, and the seeds are eaten by the natives of Ajmere, India. No. 102. Eragrcstis purshii Schrad. Southern Spear-grass. A native annual, similar in appearance to Eragrostis pilosa, and growing in similar situations. It is common from the Middle States south ward, and extends south- westward into Texas and Arizona, where it exists in a great variety of forms. It grows to the height of 1 to 2 feet. It is nowhere considered of any agricultural importance. No. 103. Erianthus raveunae Beauv. Plume-grass. A stout grass growing to the height of 8 or 10 feet, with large and plume-like pani- cles 10 to 20 inches long, resembling in some degree Pampas-grass. Cultivated for lawn decoration, as is also the variety with variegated leaves. A native of the Mediterranean region. No. 104. Erianthus saccharoides Michx. Plume-grass. A tall stout grass of striking appearance, 4 to 6 feet high, with a reddish or silvery- white showy panicle from 5 to 10 inches long. This grass ranges from New .ler- sey to Illinois and southward to the Gulf, growing in very wet places and open swamps. Of no agricultural value, but deserves notice as an ornamental grass for lawns and gardens. No. 105. Eriochloa aristata A'asey. Mexican Everlasting-grass. A branching leafy annual, 2 to 3 feet high ; native of Mexico. Seed of this grass was obtained by the Dei»artment in 1888. It was cultivated in the grass garden located at Starkville, Miss., by Prof. S. M. Tracy, who says that it is a much more promising grass than E. annidata, more hardy, less injured by drought, and produces a heavier growth. It will make two good crops of hay annually in the South, the best crop being from the second growth, which is ready to cut in October. The grass produces an abundance of seed and reseeds itself, making its production comparatively inexpensive. No. 106. Eriochloa punctata (Linn.) Hamilt. Everlasting-grass. A quick-growing, smooth, succulent perennial, 2 to 3 feet high, with flat leaves and narrow panicles 2 to 4 inches long. Widely distributed within the tropical and subtropical regions of both hemispheres. In Australia it is regarded as an excel- lent pasture grass, lasting all the year round and well liked by stock. The seed, which is produced abundantly, is easily gathered. This grass deserves the attention of Southern dairymen. In Arizona it grows throughout the valleys in irrigated soil, or in the rich moist places of the plains, yielding abundant herbage eagerly sought by all kinds of stock. No. 107. Eriocoma cuspidata Nutt. Indian Millet. (Fig. 43.) A grass of rather striking appearance, 1 to 2 feet high, widely distributed through- out the Rocky Mountain region from British America southward to Texas and New Mexico, eastward to the Missouri, and westward to the Sierras of California. It grows in dry sandy soils, forming bunches of greater or less size, and from this habit of growth it has been called, along with a number of other grasses, "Bunch-grass." It thrives in soil too dry and sandy for the growth of most other grasses, and is much esteemed for grazing in the regions where it abounds. In New Mexico this grass is by some decerned superior to grama, on account of its huge and nutritious seeds or grains, which are used by the Indians to some extent for food. 38 No. 108.

Jiixiirians, of the seed cata logues, wliich has been cultivated in various parts of the South and West, has a habit of tillering, or sending up many — 1*0 to .50 — stalks from the same root (Plate III, fig. 1). From this habit the bulk of fodder produced to the acre is very large, probably unequaled by any otlier grass. It is liked by all kinds of stock, and has especial value as a green fodder when other forage is dried up. It may be cut several times during the season, but nearly as good results will be obtained from a single cutting, made before there is any frost. The stalks are tender, and there is no waste in the fodder when dry or green. One pound of seed to the acre, planted in drills 3 feet apart and thinned to a foot apart in the drill, is recommended. It is a native of the warmer portions of Mexico and Central America. The seed rarely matures north of southern Florida. No. 109. Festuca duriuscula Lam. Hard Fescue.

Its particular merit lies in its ability to thrive on dry sandy soils unlit for the growth of bet- ter gr.-isses, and it well rt^sists long ]ieriod8 of sununer drought . It is well adajited to the cooler and mouutaiuous regions of our country, being a native of the cooler temperate regions of both hemispheres, (in well-manured, clayey land this Fescue has produced upon a single acre 18,370 pounds of green hay at time of tl<)wcring, and 8,200 pounds of hay besides 10,020 pounds of afterm;ith.

It is productive on soils which are not too dry, and, heing of long duration, is especially valuable for permanent pastures. It thrives best on moist soils rich in humus, whether marls or clays. The variety pratensis, or Meadow Fescue, is a common form, rather smaller than the species, with a narrower and fewer-flowered panicle. Variety arundinacea, or Reed Fescue (fig. 45), is a very vigorous, tall form, 3 to 4 feet high, exceedingly hardy, and yields a very large amount of hay of excellent quality, succeeding best ou lauds that are comparatively moist. The seed of Meadow Fescue is quoted in some of the New York catalogues at $3.50 per bushel or $22 per 100 pounds. A bushel weighs about 14 pounds. No. 111. Festuca heterophylla Lam. Various- leafed Fescue. A rather slender European grass, 2 to 4 feet high, with very narrow (setaceous) root-leaves, and narrow but Hat culm leaves. It is a perennial, closely related to Creeping Fescue, of which it has been made a variety by some authors. The panicle is comparatively large, open and nod- ding at the apex. It is a species preferring a rather mild climate, and grows naturally in open woodlands or along their borders. It makes its best growth on low-lying lands which are not too dry, but upon good soil it withstands pro- tracted periods of drought verj^ well. Owing to the great production of fine root leaves, this species makes a good bottom grass, and as these leaves are quite soft the grass is well adapted for lawns, and is particularly recommended for those which are too much shaded for the suc- cessful growth of other lawn grasses. It is an excellent grass, also, for woodland parks where the soil is not sandy. European authorities have classed it with the best forage i)lants. It is little known in this country, but the si ed is offered for sale by our leading seedsmen, th»j# retail ]irice being from $2.75 to $3 per bushel of about 14 pounds. j-j^ 45 _i{ee(l Fescue (Festuca da- No. 112. Festuca kingiKS. Wats.) Scribn. King's tior arandinacca). Fescue. A tall dicEcious bunch grass, common in the foothills and canyons of Colorado and Montana. It is a very robust species, and supplies a large amount of good though coarse winter forage. Growing naturally at an elevation of 7,000 to 8,000 feet, it might prove valuable in cultivation in similar localities. No. 113. Festuca ovina Linn. Sheep's Fescue. Sheep's Fescue exists iu many varieties in the Northwestern States, especially in the Rocky Mountain region. Some of these varieties attain the height of 2 or 3 feet, but for the most part they are rarely more than a foot high, producing a large amount of fine herbage, which is valuable for grazing, especially for sheep. Some of the native varieties are well worthy the attention of the agriculturist. All the forms of Festuca ovina are "bunch-grasses," and are devoid of the creep- ing roots, the jiresence of which distinguishes the Red Fescue (Festuca rubra) from this species. Sheep's Fescue is well adapted for cultivation on light, dry soils, especially those which are shallow and silicions. Although a native of this country, our seed supply comes mostly, if not entirely, from Europe, where 40 i the grass is also native. Sow 2A to 3 busLels per acre. The weight of a hushel of seed is about 14 pounds. Price per bushel, $2.25 to $2.75 in New York. No. 114. Festuca rubra Linn. Red Fescue. This grass grows along the Atlantic coast of the New England and Middle States, and in the Northern Slates, extending westward to the Pacific. Like Festuca ovina, it presents many forms, but in some respects is superior to that species, as by its creeping rhizomes it will form a compact and durable turf. On account of this habit of growth, it is a useful grass for binding moving sands along the seacoast, or cov- ering gravelly banks and dry slopes. In Germany, Red Fescue is regarded as one of the most valuable grasses for dry, sandy meadows. Owing to the great production of fine root leaves, this species makes a good bottom grass, and as these leaves are quite soft the grass is well adapted for lawns, and is particularly recommended for those which are too much shaded for the successful growth of other lawn grasses. It is an excellent grass also for woodland parks where the soil is not sandy. European authorities have classed it with the best forage plants. It is little known in this country, hut the seed is offered for sale by our leading seedsmen, the retail price being from $2.50 to $3 per bushel of about 14 pounds. A variety, F. rubra glaucescens Hack, (fig. 46), is the best pasture grass in the mountain meadows of North Carolina and East Tennessee. No. 115. Festuca scabrella Torr. Great Bunch-grass. (Fig. 47.) A strong perennial, growing in large tufts or bunches 1 to 3 or 4 feet high. A native of th<^ Rocky Mountain regions, extending from Colorado northward and westward to California and Oregon. It often occupies extensive mountain parks, to the ex- clusion of other grasses, where it affords excellent grazing. It may be cut for hay, of which it fur- nishes a large amount, excellent in (juality, espe- cially for horses. It is one of the best grasses for winter stock ranges. In the Northwest, particu- larly in the Rocky Mountain region, there aie many native sjx'cies of the genus Fcntuca which are well deserving the attention of stockmen and farmers. No. 116. Festuca teuuifolia Sibth. Slender Fescue. A low ;md tine-leafed grass, in habit of growth resem- l)liiig Fentuca oriiia, of which it is regarded as only a variety by most authors. It has no special agricultural value, but will grow in dry and comparativi'ly sterile soil. Its line, hair-like leaves and densely cespitosc haliit of growth render it a good lawn grass when ])roperly treated, especially for shady places, and it is also a good plant for edgings.

Six-rowed barley has been in cultivation since prehistoric times in southern Europe ; two-rowed barley is now largely cul- tivated in England aud central Europe. The four-rowed barleys are of later origin than the others, and are most generally cultivated in northern Europe and in this country. The bailey crop of the United States for 1895 was 87,072,714 bushels, of which amount six States jtroduced over 73,000,000 bushels, California leading with 19,023,678 bushels. Barley is the most important cereal of the far north, some of the varieties being cultivated in Norway to latitude 70°. It is employed in making bread also in northern Asia and Japan. Barley soup is an article of diet in central Europe. From naked barley {Hordeum decurllcatum) a 44 luiicilaginous tea is prepared, used in medicine. The graiu is largely fed to horses, both iu this couutry and in Europe, but the chief use is for brewing beer.

A slender aquatic grass of the Gulf States, growing along muddy banks and In eliaUow streams. Tile steins are often 2 feet or more in length, and in shallow water tlieir summits appear above the surface, while in water of greater depth the uppermost leaves are floating. The tender stems and leaves are eat- en by stock, and m:iy af- ford some food for water- fowl. No. 128. Imperata arundi- uacea Cyrill. Blady-grass. A sand and soil binder com- mon throughout the warmer temperate and tropical regions of both hemispheres. It is a stout, erect, leafy grass, 1 to 3 feet high, with sil- very-white spike-like panicles. The rootstocks form a perfect network of strong fibers, and iu warm countries the grass is recommended for bind- ing river banks, the sides of dams, and the loose sands of the coast. This grass is easily propagated by root cuttings, an<^ might be utilized along the Gulf Coast or along the Lower Mississippi in strengthening the levees. In the Malay Archipelago this Imperata is the prin- cipal grass of the Alang Alang fields, and is used by the natives for thatch- ing roofs. Cattle eat it when young with .-ippareut relish, .md in Bengal it forms a very large portion of the pasturage. The Tclingas make use of it in their nuirriage ceremonies. In western Texas and Arizona there is a native species, Imperata hookeri (fig. 52), A^ery much like the one above described, iu appearance and habit of growth. It grows naturally around the borders of .•illagation by cuttings of the rooting, pros- trate stems is probably the best mctheen little cultivated in this country, lint is occa- sionally found in the older settlements in cultivated liclds and waste grounds about dwellings. The number of grasses termed millets in various i)arts of the world is large, and includes many very ditt'erent species, whose grain, however, is used for human food. Most of the so-called millets belong to the genera Chdlochloa, I'anicum, and I'aspalum. They form the principal food grains of the natives of many parts of Africa and Asia. It has been estimated that the millets feed one-third of the human race. No. 166. Panicum molle Sw. Para-grass. A rather coarse, reed-like perennial, 1 to (> feet high, with hairy nodes, and narrow, lax i)anicles, 6 to 8 inches long. It is cultivated in .South America, and in the West Indies and Mexico, and has been introduced into some of the Gulf States. It is grown with success on the high ]»ine ridges of I'lorida, and wherever culti- vated it is most highly esteemed ami regarded as a very fattening pasture grass. How far to the north this grass may be grown successfully does not ajjpear to have been determined, but it is hardy at the Cape of Good Hope and other far extra tropical regions (Baron von Mueller). It is propagated either by seeds or root cuttings. No. 167. Panicum obtusum H. li. K. ^'ine Mesquit. A stolouifcrous grass, the runners attaining a length of 8 to 10 feet, the upright dowering culms 12 to 24 inches high. This grass ranges from Colorado to Texas, New ilexico, Arizona, and southward into Mexico. It is usually found in irri- gated lands or in the low, damp soil of the valleys, most frequently under the shade of trees and shrubs. No attempts have been made to cultivate this grass, l)ut its appearance and habit of growth indicate an agricultural value of suflS- cient importance- to call for experiments in its cultivation. In New Mexico this species is called "Wire-grass." No. 168. Panicum plicatum Lam. Palm-leafed Grass. A broad-leafed perennial, 3 to 4 feet high or more, native of India. The leaves are elegantly striate and usually i)licate, giving to the grass an unusual and at the same time attractive apjiearance. It is a favorite ornamental for greenhouse culture. No. 169. Panicum proliferum Lam. Sprouting Crab-grass. A smooth and usually much-branched native annual, with rather coarse, spreading or ascen8, it is s])oken of in the highest terms as a hay-producing grass. No. 176. Panicum virgatum Linn. Switch-grass. (Fig. 68.) A tall, native perennial, 3 to 5 feet high, with strong, creeping rootstocks, long, Hat leaves, and ami)le, spreading )ianiclt's. When young this affords good grazing, but .-it maturity the stems become hard and practitally worthless for fodder. It ranges from Maine southward to tlits Gulf and westward to the Rocky Mountains. It is particularly common near tlu^ coast in sandy soil bordering the marshes, and oftentimes plays an important parttliere, in preveutiug the drifting of sands 57 by the wiiuls or the washing of soils by overflows aud high tides. On good lands it is very productive, and if cut before the stems have become hard yields a large amount of hay of very good quality. No. 177. Pappophorum laguroideum Schrad. A handsome ornamental, 3 to 5 feet high, with narrow, plume-like panicles a foot or more long. It is a native of Mexico, and has been successfully grown from seed on the grounds of the Department of Agriculture. It is worthy of introduction as an ornamental for gardens aud lawns because of the beauty of its pale straw- colored panicles. No. 178. Pappophorum wrightii S. Wats. Purple-grass. A slender and apparently annual grass of western Texas, New Mexico, and Arizona, growing on the open plains and among the foothills of the moun- tains. It has short, narrow leaves and narrow, densely flowered heads or panicles, which are softly bearded and grayish or l^urplish. It is said to be fuUy equal to Grama or Buffalo-grass innutritive value, and more pala- table to horses or mules. No. 179. Paspalum bosciauum Fliigge. Purple Paspalum. A rather stout perennial with ascend- ing branching stems, 2 to 3 feet high, long, flat leaves, and numer- ous racemes crowded near the summit of the culm and its branches. It is a native of the Southern States, growing in moist grounds, preferring rather heavy soils. Like other species of Pas- palum, it grows in tufts and often occurs covering consider- able areas to the exclusion of other grasses. It yields a good bulk of sweet hay, but is rather slow in drying. No. 180. Paspalum compressum (Sw.) Nees. Carpet-grass. A slender, erect, or more frequently prostrate and extensively creep- ing perennial, rooting at the nodes, and sending up numerous leafy, flower-bearing branches, 6 to 24 inches hinrh. The verv slender racemes or spikes borne at or near the summit of the stems are 1 to 3 inches long. The prostrate creeping stems spread rapidly, and soon form a dense, carpet like growth, crowding out all other vegetation. It withstands protracted drought, grows well on almost any soil, and in the more southern districts is evergreen, yielding good pasturage both summer and winter. It is regarded as one of the most valuable native pasture grasses of the regions bordering the Gulf, and is a most excellent lawn grass, superior to Bermuda and less difficult to eradicate. It is found in the warmer regions of both North and South America. It is readily propagated by sets and seeds. Fig. 69. — Carpet-grass {Paspalum coinprcssrtm): a, attachment ofspikelets to racliis; b and c, spikelets; d, floret. 58 No. 181. Paspalum dilatatum Poir. Large Water-grass. A rather coarse leafy perennial, growing in clumps 2 to 5 feet high, bearing near the summit of the stems two to ten, more or less spreading racemes or spikes of crowded, hairy spikelets. It is a native of Brazil and possibly was originally introduced into the Southern States (where it has become ([uite widely distributed) from that country, although it may be a native here. It ranges northward from the Gulf to southern Virginia and Tennessee, and westward to Texas, growing most abundantly on low, black soils, which are well supplied with moisture. It is considered an excellent pasture grass, and when well established endures seasons of ex- cessive drought without injury. It is particularly val- uable as furnishing excellent late summer and autumn feed, during which period it makes its principal growth. No. 182. Paspalum distichum Linn. Knot-grass. (Fig. 70.) A low creeping species, resembling Bermuda-grass. It is common in the Southern States along the seacoast and in the interior, extending southward from Virginia to the Gulf, and westward to Texas, Arizona, southern Cali- fornia, and northward to Oregon. It occurs throughout the tropical regions of both the Old and New Worlds. It grows in more or less sandy soils around the margins of ponds and along river banks. In such places it often does good service in binding soils subject to wash. The grass can well be recom- mended for this use. Its stems are somewhat succulent, extensively creeping, rooting at the nodes. The leaves are tender, affording excellent grazing. The upright stems are a few inches to a foot high, and bear at their summits two slender spikes. This character at once serves to distinguish it from Bermuda, which has several spikes at the apex of the flowering culms. No. 183. Paspalum laeve Michx. Smooth Pas- palum. (Fig. 71.) A tufted native perennial, with ascending or erect 8t((ms, 1 to 3 feet long, liat leaves, and two to five, more or Ifss spreading spikes, 2 to 1 inches long. Common in the Middle and Southern States, growing in open fields, meadows, etc., usually where the ground is somewhat moist. It is a late summer grass, blossoming from .July to October. Well liked by all ivinds of stock. In cultivated grounds, and particularly on lawns, which it occasionally invades, it must tee classed as a weed. Fig. 70. — Knot-grass {Pas- palum dintichum). Fio. 71.— Smooth P.ispalum (Patpalum lii'Ve). f 59 No. 184. Paspalum scrobiculatum Linn. Ditch Millet. A smooth uniiuul, with branching, erect or ascending steins, 2 feet high or more. Widely distribnted throughout the tropical and subtropical regions of both hemispheres. In northern India this grass is cultivated throughout the plains- region as a "rainy-season crop," It is usually sown on the poorer kinds of soil, the grain being chiefly consumed by the lower classes. The straw is used for fodder. (Duthie.) A variety of P. scrobiculatum, called "hureek'' in India, which is perhaps the Ghohana-grass, an Indian species reputed poisonous, is said to render the milk of cows that graze iipon it narcotic and drastic. (Lindley.) No. 185. Pennisetum japonicum Trin. Erect, with flattened simple stems, 1 to 2 feet.high, very narrow leaves, and compara- tively loosely flowered purplish or yellowish nodding panicles. A native of Japan. Occasionally cultivated as a curiosity or for ornament. No. 186. Pennisetum latifolium Spreng. A rather broad-leafed ornamental perennial, 3 to 5 feet high, branching above, with greenish rather dense panicles U to 2 inches long. Native of Uruguay and Argentina. In the latter country it is used for covering roofs of houses. Occa- sionally found cultivated here as an ornamental grass. It forms large tufts and is easily propagated by the roots or seeds. It may possess some value as a forage plant. No. 187. Pennisetum macrourum Trin. A South American species, with unbrauched stems, 3 to 4 feet high, and densely flowered, cylindrical, yellowish panicles 6 to 8 inches long. Cultivated occa- sionally for its odd and ornamental appearance. No. 188. Pennisetum spicatum. Pearl Millet. An annual of luxuriant growth, 6 to 10 feet high, with long, broad leaves, stout culms, and terminal, erect, cylindrical, dense spikes 6 to 12 inches long, closely resembling those of the common cat-tail of the marshes. It is a native of the East, where it has been cultivated for its grain for many years. It is an impor- tant agricultural grass of Central Africa. It requires a rich loose soil to obtain the best growth, and under favorable conditions produces an enormous (xuantity of green fodder, for which purjiose it can be cut several times during the season. It does not dry out readily and is often difficult to cure into hay. It has been cultivated with success as far North as Pennsylvauia and in many parts of the South for a good many years. It is best sown in drills, about 2 feet apart, and 5 to 6 pounds of seed are required per acre. The weight of good seed per bushel is 56 pounds. The current price is $12 to $14 per 100 pounds. No. 189. Pennisetum villosum Brown. An Abyssinian species which has been introduced into cultivation because of its ornamental appearauce. It grows to the height of 1 or 2 feet, has long narrow leaves, and dense, oblong or cylindrical, finely bearded heads 2 to 4 inches long. It is a hardy ])erennial, graceful and attractive in appearance, and is very frecjuently cultivated as an ornamental under the name oi Pennisetum ton best graz- ing grasses of the Rocky Mountains and promises to do well in cultivation. No. 211. PoUinia fulva Heiith. Sugar-grass. A slender or rather stout perennial, 1 to I feet high, with narrow leaves and two to tiirec terminal sjiikos, which are clothed with brown, silky hairs. It is a Fifi. 7(5.— Kent iiiliv Blue-grass (Poa pm ten sis). 65 native of Australia, found througliout all the colonies of that country, growing chiefly on the richest soils and on deep alluvial flats bordering rivers and creeks. It is prodiictive, and much prized by cattlemen. The name "sugar-graes" is applied to this species ou account of the sweetness of its stems and foliage. Mr. Fred Turner recommends it for cultivation on good land, especially in grazing districts, and he speaks of it as being a good grass to plant on the banks of rivers, creeks, and dams, as its strong, penetrating roots would help to bind the soil and prevent its being washed away by heavy rains or floods. This grass is classed as a variety of Pollinia cumminyii Nees, bj^ Hackel. No. 212. Puccinellia maritima (Huds.) Pari. Sea Spear-grass. A slender grass, 12 to 18 inches high, with creeping rhizomes. It occurs in the marshes along the seacoasts of New England and the Middle States, and forms a valuable element of the hay of tide- water marshes. No. 213. RedQeldiaflexuosa(Thiirb.) Vasey. Eedfield's-grass. (Fig. 77.) A stout, native perennial, 18 inches to 4 feet high, with long, narrow leaves and difl'usely spreading pan- icles, growing in the sandy districts of Nebraska, Colorado, and Kan- sas. It has deeply penetrating and widely spreading underground stems or rhizomes, making it a val- uable species for binding drifting sands. It is a characteristic grass of the sand hills of central Nebras- ka, growing in the drifting sands and "blow-outs," and is a conspic- uous and almost the only grass found on the sand dunes south of the Arkansas River, near Garden City, Kans. No. 214. Saccharuni ciliare Anderss. A tall, handsome grass of India, with smooth stems, 8 to 10 feet high, long leaves, and large, showy pani- cles of silky-hairy flowers. Used in the manufacture of mattins:, rope, and paper, and for thatching. The stems are made into sieves, scieens, and baskets. The thicker portion of the stems is used for lining wells, and in making chairs and C(>uche.s. The leaves are sometimes used for fodder, and when young the grass is grazed by cattle. No. 215. Saccharum officinarum L. Sugar Cane. A stout grass with many-jointed stems, 8 to 15 feet high, broad leaves, 3 to 4 feet long, and long (16 to 32 inches), pyramidal panicles. Native country unknown, but .sparingly spontaneous in the South Sea Islands, Avhere it blo,ssoms freely. Cultivated in all tropical countries. Propagated chiefly by cuttings of the stems. There are many varieties, distinguished chiefly by the color and height of stem. The leaves arc sometimes used for fodder, and, to a limited extent, also in paper making. The cane is cultivated, however, for its sweet juice, which yields from 12 to 20 per cent sugar. Fnder favorable circumstances an acre of ground will produce about 20 tons of cane. In this country the production of cane sugar on a commercial scale is practicallv limited to the States of Loui- ^393— ]S"o. 14 5 Fig. 77 — Redfielfl's-grass {Redfieldia flexuosa). 66 Biana and Texas. The sugar production in Louisiana in 1889 was 292,124,050 pounds. Tbf world's production of cane sugar was then aliout 3,000,000 tons, more than one-third of which was produced by the West Indies. Molasses is a product of sugar cane (the uncrystallizable sugar), and rum is made from molasses. Refuse cane, from which the juice has been expressed, yields a strong liber, and in parts of India is used for torches, etc. No. 216. Savastana odorata (Linn.) Scribu. Yanilla-grass. (Fig. 78.) A rather slender, sweet-scented perennial, 1 to 2 feet high, with short culm leaves and brownish i)anicles. Moist meadows and mountains of the Northeastern States, extending we.stwai"d to Oregon. This grass, remarkable for its fragrance, has long, creeping rhizomes, from which spring the lloweriug culms and numerous Fig. 78. — A'jinillagrass {Suva- xtana odorata). Fig. 79. — Cord-grass (Spartina cyncsu- roides) . Fiep, and bunches of it are hung over beds fr)r this purpose. It makes a good turf, but is of little value for forage. In the Northwest Vanilla-grass is generally called Sweet-grass. No. 217. Secale cereale Linn. Rye. An annual. I to 6 feet high, with liat leaves and a terminal, somewhat liattened, bearded spike 1 to (i inciies long. The rye cjop of tiie I'liited States in 1805 was 27,210,070 bushels, nearly half of which was produced in the States of 67 Pennsylvauia, New York, and Wisconsin. Eye is more largely cultivated in central and northern Europe than in America; the grain is there very largely- used for making hread. It is comparatively little used in this country for that purpose, being chiefly employed in the maoinfacture of malt and spirituoua liquors. The straw, which is longer than that of other grains, and more uniform in size throughout, is employed in the making of a great variety of articles, such as paper, hats, bonnets, mats, slippers, toys, and fancy articles. Rye straw is little valued for fodder, but when green it is esteemed as a forage plant, and is sometimes sown for this piirpose in the Sonthei-n States, cattle being allowed to graze on it during the fall and winter months. For winter graz- ing it should be sown upon well-prepared land early in August, Avhen it will be ready to pasture or to cut green in the latter part of October, and may be grazed through- out the Aviuter months. No. 218. Spartina cynosuroides (Linn.) Willd. Cord- grass. (Fig. 79.) Stout, with erect, simple stems 2 to 9 feet high, fiat and long-pointed leaves, and numerous erect or spreading spikes 2 to 5 inches long. This is a native, common along our ocean and lake shores, borders of rivers, -etc., ranging from Elaine to the C'arolinas, and westward to the Pacific. It makes a fair but rather coarse hay Avhen cut early, and has been successfully employed in the manufacture of twiue and paper. The strong, creep- ing, scaly rootstocks of this grass adapt it for binding loose sands and river banks, and in the AVest it is used for thatch. No. 219. Spartina patens (Ait.) Muhl. Fox-grass. (Fig.80.) A rather slender species, 1 to 2 (rarely 3 to 4) feet high, with two to four sknder, erect, ov widely spreading spikes. This is common upon the salt marshes, and is one of the most valued species which go to form the salt hay that these marshes produce. It ranges from Maine southward to Florida and along the Gulf coast to Texas. It is useful for packing glassware, crockery, etc., and in the larger towns along the coast is much used for this purpose. Fox-grass and lilack-grass (Jun- cus gerardi) are regarded as the best of the grasses of the salt marshes for the production of hay, and chemical analyses have proved the correctness of this opinion. Salt hay, composed chiefly of these grasses, at average market prices is decidedly cheaper than timothy hay. No. 220. Spartina striata inaritima (Walt.) Scribn. Creek-sedge. (Fig. 81.) An erect and often stout salt marsh grass, with fiat leaves, and few to many erect spikes. It varies a good deal in size, the larger form attaining a height of 5 to 8 feet. It grows along the ditches and creeks of the marshes, and is conspicuous by its size and long, shining leaves, which are of a deep green color. Smaller forms are found over the marshes away from the ditches, and these often are of a pale- green tint, with comparatively short and shining leaves. All the forms are somewhat succulent and have a rank odor, which is imparted to the milk and butter of cows feeding upon them. The species is of little value for fodder, but makes excellent thatch, and is used to some extent for litter and mulching. This is a characteristic grass of the salt marshes, and is found along both the Atlantic and Pacific coasts of our country and on the shores of Europe. No. 221. Spinifex hirsutus Labill. Spiny Rolling-grass. (Fig. 82.) A sand binder of the coasts of Australia, New Zealand, and Tasmania. It has stout, Fig. 81. — Creek -sedge (f^par.tina striata man- tima) 68 creeping stems, rooting at thejoiuis, and sending np coarse, Irafy tnfts. The Avliole plant is flotlied with soft hairs. The male and female llowers are bornt^ ou separate plants, the latter in globnlar heads, which fall oflF at matnrity and are driven over the sands by tin- winds, dropping their seeds as they roll along, or are carried abont by the waves and deposited on newly formed sand bars, there to continue the emljankiug process. It has no vahic for forage, but in New South Wales is regarded a most useful grass for fixing drift sands when encroaching upon valuable lauds. It is readily propagated by cuttings or joints of the stem.s, is of comparatively (piick growth, and is very persistent when once established. It would doubtless bo of some value on our own South orn and Californian coasts as a sand binder. No. 222. Sporobolus ai- roide.s Torr. Alkali Sac- caton. (Fig. 83.) A stout ratlier coarse and rigid grass, growing ou tussocks in sandy and more or less alkaline or saline soils along rivers and streams, ranging from Montana south- ward to Texas and westward to Califor- nia. It has a widely s p r e a d i n g ]> a n i e 1 e, more open than sacca- ton, and the grass rarely exceeds 2 feet in height. In some places in Nevada, I'tah, aud New Mexico it occurs abundantly, and yields a coarse fodder, which is eaten by stock wlien more tentler grasses are not available. No. 223. Sporobolus as- perifolius (Nees and Mey.) Tlinrb. Fine-top Salt-grass. A low, somewhat creeping grass, 6 to l."> inches high, with numerous short, spreading, acute leaves, and an expanded eapillarv i»ani(le 'A to o inches long. It grows ou alkaline plains from Texas ncjrthwest to itritish ('r)lnmbia, in similar situations as JHsticIiliii sphalu. andlike that species often forms a dense, continuous turf. It grows well on strongly alkaline soil, and may prove valuable for propagation on such lands. No. 224. Sporobolus cryptandrus (Torr.) A. (iray. Dropseed. Astronjily rooted jjereniiial, 2 to 3 feet high, with usually narrow, rather densely dowered panicles, which are generally jtarti.dly inclosed within the upper Icaf- rio. 82. — Si)iiiy Iiolling-gr.i88 {Spini/cx hiisuUa) : a, nialo iuflores- cence; 6, feiiialo iiilloreHceiice; a', iiinle spikelet; h', female spikelct. 69 sheath. Common on the Western plains and in the Rocky MoTintain region. It is a tender species, apparently well liked "by stock, and where it occurs abun- dantly is very generally regarded as an important forage plant. In northern central Kansas it is spoken of as one of the best early grasses, and the same is said of it in Young County, Texas. No. 225. Sporoboliis indicus (Linn.) E. Br. Smiit-grass. (Fig. 84.) A tufted, wiry, erect perennial, 1 to 3 feet high, with narrow, densely flowered, spike-like panicles 4 to 12 inches long. This grass is widely distributed through- out the warmer temperate regions of the world, and has become quite common in many parts of tlie Southern States, growing in scattered tufts or patches about dwellings and in dry, open fields. As the season advances, the long, slen- der panicles often become overgrown by fungus, so that they appear as if Fig. 83.— Alkali Saccaton (Sporobolus uiroides). Fig. 8-t. — Smut-grass {Sporobolus in- dicus) . attacked by smut ; hence the common name " Smut-grass."' By some it is looked upon as valuable for forage, but the stems soon become too tough and wirj' to be readily eaten by stock, and in fields where this grass occurs it is usually avoided by cattle when other food can be had. No. 226. Sporobolus junceus (Michx.) Kuntli. Rush-grass. Common in the dry, pine-barren regions of the Southeastern States. It grows to the height of 18 inches to 2 feet, and is df little or no agricultural value. This and Arintida stricta are known throughout the South as " Wire-grass." No. 227. Sporobolus orientalis Kth. Usar-grass. A wiry, creeping perennial, witli rather short, rigid leaves and diffuse panicles. It is a native of India, growing upon saline soils, often constituting the entire veg- etation of the extensive "usar" tracts of northern India. A valuable grass for 70 alkaline or saline soils, yielding a liberal supply of fodder where other plants are unable to exist. No. 228. Sporobolus -wrightii Munro. Saccaton. (Fig. 85.) A stout, erect perennial, 4 to 8 feet high, with long, narrow leaves and a slightly spreading panicle 12 to 36 inches long. It grows in great clumps, jiroducing a large quantity of coarse, tough stems and leaves, which, however, in the regions where this grass is native — Arizona and New Mexico — yield a hay which is valued for liorses and mules. As a hardy perennial for saline bottoms subject to Hooding or incapable of cultivation, this species deserves notice. The Indians and Mexicans of Arizona and Lower California call all hay grasses "zacate," without any distinction between the species. No. 229. Stenotaphrum dimidiatum (Linn.) Brongn. St. Augustine-gra.s.s. (Kig. 86.) This grass has a wide distribution, being found in the tropical and warmer temperate regions of both the Old and New World. In New South Wales it is known as Buifalo-grass, and in Jamaica it is called Pimento-grass. It grows upon every variety of soil, from the apparently sterile sand dunes to heavy clays, but is rarely found far away from the coast. The flattened stems emit tibrous roots at every joint, where they also readily separate, each piece becoming anew center of growth. The leaves are flat or simply folded, blunt or obtuse at the apex, nearly one-fourth of an inch broad and I to 10 inches long. Tlie Ho weriug stems grow to the height of 6 inches to a foot or more. St. Au- gustine-grass grows along our ocean shores as far north as South Carolina, and is extensively used for lawns in Charleston, S. C, and cities in the South ueav the coast. It is useful for holding sloping embankments, especially those subject to wash. It is propagated by cuttings or sets, and quickly eo\ ers the most sandy yards with a dense, carpet like growth. In South America the creeping steins are (Muployed in medicine as a diuretic. This is the Bufl'alo-grass of Australia, and other local names in this coun- try are Mission-grass and Charleston Lawn- grass. No. 230. Stipa oomata Trin. & Kupr. Needle-aud-Thread. ThLs is one of the bunch grasses common in the Rocky Mountain region, growing on the dry mesas and foothills. It is a rather stout, leafy perennial, 1 to 3 feet higli, with a panicle usually partly inclosed in the upper leaf sheath; the slen- der awns of the spikelets are 4 to 6 inches long and llexuose. This grass lias some value, all'ording forage of good (piality in the regions wiiere it grows abundantly. In Dakota, Wyoming, etc., it is valued as a hay grass. No. 231. Stipa elegantissinia Labill. A native of Australia, with erect, branching stems 2 to 3 feet high, narrow leaves, and loose panicles 6 to 8 inches long. Tiie axis and long, thread-like branches of the )):iniclc are elegantly plumose with tine, spreading hairs, rendering it highly ornamental. Cultivated in gardens. Fig. 85. — Saccaton (Sporobolus wrightii). 71 No. 232. Stipa leucotricha Trin. & Rupr. Bearded Mcsquite. An erect perenuial; 1 to 3 feet high, with very narrow leaves and a loose panicle with a few loug-awned spikelets. One of the best native hay grasses of central and southern Texas. No. 233. Stipa pennata Linn. Feather-grass. A native of southern Europe, 1 to 2 feet high, growing in dry, open ground, and often cultivated in gardens as an ornamental, the very long, slender awns being clothed with spreading, silky hairs, presenting a very graceful plume-like appearance. A variety of this grass {Stipa pennata neo-mencana) grows wild in the mountain regions of western Texas and Arizona. It is an elegant form of the species, growing in clumps 6 to 12 inches in di- ameter, and is deserving the attention of the florist. No. 234. Stipa setigera Presl. Bear-grass. A native of California, extending northward to Oregon and eastward through New Mexico and Arizona to Texas. It is common on the coast ranges and on the foothills of the Sierra Nevada, where it is re. garded as one of the most valuable of the native bunch grasses. No. 235. Stipa spartea Trin. Porcupine-grass. Rather stout, 18 inches to 3 feet high, with long leaves and few-flowered panicles. The stout and twisted awns are 3 to 6 inches long, and at the base of the flowering glume is a long and very sharp- pointed callus. When mature, the awned flowering glumes soon fall off, leaving the large, pale, straw- colored, persistent empty glumes, which impart to the panicle a characteristic oat-like appearance. The awns, when dry, are bent and very strongly twisted, but when moistened they gradually untwist, a character which enables the seeds to bury them- selves in the ground, this being possible on account of the very sharp callus at the base of the fruiting glume. The same character also renders the seeds of this grass dangerous to sheep, as they readily become attached to the wool, and may penetrate the flesh of the animal, causing serious injury. Aside from this danger of aff'ecting the quality of the wool, and possibly the life of the sheep, this grass may be considered a good forage plant, as it makes a very good hay, although somewhat coarse. It is particularly common in the prairie regions of Iowa, Nebraska, South Dakota, and Minnesota, extending westward to the Rocky Mountains, where it frequently occurs upon the dry foothills and bench lands. This is the Butt'alo-grass of the Saskatchewan region. In some localities it is Fig. 86.— St. Avigustine-grasa (Stenotaphrum dirnidiatum) . known as Needle-grass, but that name is reserved for Aristula fasciculata. also known as "wild oats" in North Dakota. It is No. 236. Stipa tenacissima Linn. Esparto. A native of the sandy regions of southwestern Europe and northern Africa. It is a tall perennial, with long, stiff, and very tough leaves, from which ropes, baskets, mats, hats, and other articles are woven. The leaves are employed largely in England and this country in the manufacture of paper, for which purpose this grass is superior to straw. It is one of the most important articles of export from Algeria, and from northern Africa and Spain more than 2,000 tons of Esparto are exported to Great Britain annually. "Ten tons of dry Esparto, worth from $18 to $25 per ton, can be obtained from an aci'e under favorable circumstances." 72 The grass will grow ou almost any kind of soil, from that whith is poor and sandy or gravelly to heavy calcareous and clayey soils. It thrives in the dry and hot climates of northern Africa, where many millions of acres are covered almost exclusively with it. This grass is extensively cultivated in the south of France, and possibly its introduction into some of our Southwestern districts may render profitable, regions now practically worthless. It may be propagated by seeds or by divisions of the root. The latter is the more common method. This and Lygeum spartum constitute the Esparto of commerce. No. 237. Stipa vaseyi Scribu. Sleepy-grass. A stout bunch-grass 3 to 5 feet high, which grows in the Rocky Mountains at an altitude of from 5,000 to 6,000 feet. This grass, although producing a large bulk of stems and leaves, is regarded with suspicion by stockmen. It is said that when this grass is eaten in a fresh state by horses it has a narcotic or i)oisonous oftVct, causing the animals to become crazed or "locoed," its action thus resembling that of the deadly loco weed {AfttraijaJus moJUssimus). Hay made from this grass does not appar- ently possess any poisonous qualities. No. 238. Stipa viridula Trin. Feather Bunch- grass. (Fig. 87.) A rather slender grass, 1 to 3 feet high, growing in the Rocky Mountain region and on the foothills and mesas, from British Columbia southward to Mexico and westward to the coast On good land, under irrigation, this grass attains the height of 3 feet or more, and is by far the most valuable of the Stipas for hay. The leafy culms are terminated by a narrow, many-flowered panicle of compar- atively small and rather short-awned spike- lets. The seed may be easily gathered. The callus at the base of the fruiting glume is short and barely pointed and not produced into a long, very sharp, spur-like extension, as in Porcupine-grass. No. 239. Thuarea sarmentosa Pers. A low, extensively creeping grass, rooting at the joints, with ascending flowering branches, short leaves, and slender spikes about an inch A native of Ceylon, northern Australia, etc., growing on the sands of the coast. It is a tender grass, and may be useful in binding coast sands in tropical countries or in the formation of lawns. No. 240. Trichloris blanchardiana Scribn. A perennial, H to 3 feet high, with flat leaves, and six to eighteen slender, bearded spikes, which are 2 to 5 inches bmg, digitate or fasciculate at the apex of the culm. It has long been known to florists under the name of Chlorojish hlaiich- ardiaiia, and is esteemed as an oruauu'utal grass, its attractive appearance mak- ing it worthy of attention South America. Fig. 87.— Feather Buncb-grass (Stipa viridula). long. It grows in Arizona and Mexico, extending into No. 241. Tricholaena rosea Neos. A South African annual (?), with diffusely branching stems 2 to I feet high. The spikelets are in loose panicles, and clothed with reddish, silky hairs. It pre- 73 sents a pleasing appearauce when in flower, and the panicles are valnod for dry bouquets. It has recently received souie attention by agriculturists on account of its very vigorous rapid growth and productiveness. Experiments made in this country and elsewhere indicate that it possesses much value as a meadow or hay o-rass in mild climates. Three hundred stems have been counted on a single plant. These stems take root wherever they touch the ground, and an acre has been calculated to yield 30 tons of green fodder in the rich valleys of the Macleay Elver, New South Wales. It is easily propagated by seed. No. 242. Triodia exigua Kirk. A little alpine grass, endemic in New Zealand. It forms even plots of turf, often many square yards in extent ; the leaves are firm, short, and shining ; the com- pact growth of the turf or sward prevents the encroach- ment of other grasses or weeds. It is particularly to be recommended for croquet lawns, never reciuiring mowing (Kirk). In the mountain regions of the West are sev- eral of these small turf-forming grasses, which would, if cultivated, make excellent carpet-like lawns in the region of the Northern and Middle States. No. 243. Triodia seslerioides (Michx.) Beuth. Fall Red- top. A stout, erect, native perennial, 3 to 5 feet high, with long, flat leaves and an ample, spreading, usually purple pan- icle 6 to 12 inches long, growiug in dry or sandy fields from southeru New York southward and westward to Missouri, blooming in August and September. It is a striking grass, and often covers considerable areas, but 18 apparently not liked by stock, and is not recognized as itossessing any agricultural value. Linn. Gama-grass. No. 244. Tripsacum dactyloides (Fig. 88.) A tall, coarse perennial, 3 to 8 feet high, growing in large tufts, and producing a great mass of broad leaves, which when young and succulent are eaten with avidity hy all kinds of stock. When abundant it aflords a large amount of natural forage, and is valuable to this extent. It has very strong, creeping rootstocks, and the quan- tity of forage produced is large and of excellent quality. The grass may be deserving of cultivation for forage under certain conditions, and it makes an interesting and attractive plant for lawn decoration or the garden, moist soil 18 best suited to it. Fig. 88. — Gama-grass {Tripsaevm dactyloides) . A rich and rather No. 245. Trisetum. pratense Pers. Yellow Oat-grass. A rather slender, loosely tufted perennial, growing to the height of 2 feet. It is a native of Europe, northern Africa, and western Asia. It occurs along roadsides, in open fields, and on grassy mountain slopes, where its i^iesence is said to indi- cate land of good quality. In Europe, Yellow Oat-grass is classed with the best fodder plants and is highly valued for temporary, but more particularly for per- manent pastures. It can be grown on almost every variety of soil, is fairly pro- ductive, and is readily eaten by stock. This grass has a record of yielding on clayey loam soils 8,167 pounds green grass, 2,858 of hay, and 4,083 of aftermath per acre. In this country it has received little attention. It is quoted in New York seed catalogues, the price ranging from $70 to $115 per 100 pounds. Sown only in mixtures. 74 No. 246. Triticum aestivum Linn. Wheat. Wheat in its many varieties is one of the most important of the true grasses. It is one of the oldest of the cultivated cereals, the grains having been found in very ancient Egyptian monuments, dating back to 2,.500 or 3,000 B, C. The numerous varieties are distinguished by the firmness of the axis of the spike (continuous), or its brittleness (articulated) ; by the presence or absence of awns or beard; by the color of the chalf, and color and size of the grain. Triticum astirnm speltiim, of -n-hich there are a number of subvarieties, is one of the oldest grains, and was everywhere cultivated throughout the Roman Empire, forming the chief grain of Egypt and Greece. It is still grown to some extent in parts of Europe, notably in northern Spain and southern Germany. In 1895 the wheat crop of the United States was placed at 467,102,947 bushels, while the wheat crop of the world is estimated at 2,400,000,000 bushels. For a discussion of the classification of the vari- eties of wheat, see Hackel's True Grasses (English translation), and the Fourth Annual Report of the New York Agricul- tural Experiment Station, 188.5. No. 247. Triticum polonicum Linn. Wild- goose Wheat. A very striking species or variety of wheat, with large, compressed, and usually bluish- green spikes or heads. The native coun- try of this Triticum is not known, but it probably originated in Spain, where it is now cultivated to a considerable extent. It is also cultivated more or less in Italy and Abyssinia. The long and slender fruit resembles rye, but is on the whole larger. It has sometimes been advertised by seed dealers and sold to farmers under the name of (iiant Rye. It is inferior to many other varieties, for, although the heads present a fine appearance, the production of ker- nels is small; consequently the yield of grain is light. No. 248. Uniola latifolia Michx. Hroad- leafed Spike-grass. (Fig. 89.) Erect, with rather stout, leafy stems 2 to 4 feet high, and drot)i)ing panicles of large. Hat spikelets. The leaves are broad and widely spreading, and these, togetlicr with the graceful, nodding, open panicles, render it pleasing in appearance and worthy of cultivation for ornament. It has very strong, creeping roots, and is found chieriy along streams and thicket borders from Fcnnsylvania southward and westward to Illinois. A grass of little or no agricultural value. No. 249. Uniola pauiculata Linn. Seaside Oats. A native, with stout, erect stems 3 to 5 feet high, long, rigid leaves, and showy nod- ding panicles of broad, pale straw-colored spikelets. The panicles are gathered for dry bou" Chicken Corn 27 Chloris gracilis 74 polydactyla 74 Chloropsis Llauchardiana 240 Coast Couch-grass 252 Cock's-foot 81, 158 Cock-spur 66 trrass 68 5 175 22 ir.2 liOO 195 18 Colorado Blue-stem grass Saud-grass Common Manna-grass . .

TRACY, Formerly Director of ihe Mississippi Af/riciiltural Experiment Station. PREPARED UNDER THE DIRECTION OF THE AGROSTOLOGIST. WASHINGTON: GOVERNMENT PRINTING OFFICE. 1898. LETTER OF TRANSMinAL. U. S. Department op Agriculture, Division of Agrostology, Washington, I). C, July 15, 1898. Sir : I have the honor to trausmit herewith, aud recommend for i)ub- lication as Biilletiu No. 15 of this Division, a report by Prof. S. M. Tracy, of Mississippi, ou the Forage Plants aud Forage Resources of the Gulf States east of Texas. This report is iu liue with the investi- gations of the grasses and forage plants of the South now being car- ried ou by this Division. The grazing and forage problems iu the South are of great impor- tance; keen competition is compelliug the adoption of a more diversi- fied system of agriculture than has existed iu the past. Fine cattle and good milk and butter are more profitable than cotton, and there is an increasing demand for good hay aud i)asture grasses and other for- age crops. The climate is excellent for the growth of raauy kinds of grasses, and the soils are for the most part good or readily susceptible of care and cultivation. There are between 300 and 400 species of grasses in the five Gulf States east of Texas. One observer has found in the State of Alabama alone 255 kinds. A large proportion of these grasses are unknown in the Northern and Western States, being peculiar to the Gulf coast region. This abundance of native grasses indicates that the South is naturally a good grass country, and there are wide areas in each of these States which may be profitably devoted to the formation of meadows and pastures. The value aud adaptability of these many kinds, and of foreign sorts as well, to special purposes, or to local conditions, ought to be systematic- ally investigated. The work of determining the most practical methods of introducing and cultivating those grasses which are most likely to succeed and which will at the same time be best suited to meet the needs of the stock raisers and dairymen, has been approved by you, with instructions to this Division to begin an investigation of the grasses and forage plants and forage problems of the Gulf States. Particular attention will be given to noting the abundance and value of the native forage plants and the possible methods to be employed in maintaining or improving the existing conditions of pasturage and forage supplies. A circular letter requesting information relative to the points involved 3 4 in the investigation was sent to parties interested in tlie work i^roposed, and many replies containing much valuable information bearing on the subject have been received. In connection with the preparation of the present report, Professor Tracy made a large collection of the native Southern grasses, and fur- nished the l^ivision much valuable information relative to the preva- lence and distribution of the species. The data thus acquired, together with that afforded by collections in the National Herbarium, will be used in preparation of a list of the grasses of the South, while the infor- mation contained in the replies to the circular letters above referred to will be used in the compilation of a report of a more practical nature. The illustrations for the present bulletin have been carefully selected by the Agrostologist from the drawings prepared under his supervision. Eespectfully, F. Lamson-Scribner, Agrostologist. Hon. James Wilson, Secretary of Agriculture. CONTENTS. Pa^e.

Until within the last fifteen years it was commonly believed that good pastures did not exist in the Gulf States of Louisiana, Mississippi, Alabama, Georgia, and Florida, and that good hay could not be made in that region. With rare exceptions the pastures used were composed of the wire grasses and broom sedges of the pine woods, and the larger part of the hay which was found on the market, even in the smaller towns, was brought from the Xorth. The work which has already been done by the United States Depart- ment of Agriculture, together with that of many intelligent planters, has demonstrated that the soil and climate of the Gulf States are such as will produce a heavy yield of forage, and that the quality of Southern- grown hay is fully equal to that of any which can be imported from other localities. SOILS OF THE GULF STATES. The soils of the Gulf States, excepting a small area in northern Ala- bama and Georgia, are all alluvial. They may be subdivided into six quite distinct sections with quite ditterent types of soil. These are : (1) The treeless prairie region of southwestern Louisiana. This region is mostly low, intersected by numerous rivers and bayous, and the soil, a sandy loam, is of wonderful fertility. (2) The Gulf coast region, including a narrow strip along the coast from Louisiana to Florida. This region has a rather sandy soil, often quite light on the immediate coast, but becoming more loamy and usually underlaid with a heavy clay formation a few miles back from the beach. (3) The pine woods region, extending from central Louisiana eastward to Georgia and northern Florida. The soil in this region is usually a sandy, easily worked loam under- laid with clay, becoming lighter toward the South, where it merges into the alluvial soil of the coast district. (4) The clay loam region of the upper or northern section, extending from northern Louisiana to central Georgia. 9 10 In tliis region the pine growth is more or less mixed with oaks, hick- ories, and other deciduous trees. The soil is variable, bdng rich and fertile along the creek bottoms, but harder, drier, and often somewhat sterile on the hills. These lauds often suffer seriously from washing. (5) The black i)rairie region of northeastern Mississippi and western Alabama. The soil in this region is black, rich in lime, and affords some of the best grass lands in the South. (G) The river bottoms. While five of the divisions or regions named above are in irregular belts extendi ug from west to east, all are crossed by rivers, the Ked, Mississippi, Pearl, Tombigbee, Chattahoochee, and others, which flow in a southerly direction. Much of the land along these rivers is of very recent formation and is quite different from that of the neighboring hills. It is generally extremely fertile, but often suffers from overflows and for want of drainage. In each of these regions wide variations of soil may be found, and these difierences occur sometimes on a single farm. NATURAL PASTURES. The natural forage plants vary as widely as the soils. Some adapt themselves to almost any situation and are quite general in their dis- tribution, while others are extremely local; some become more vigorous and abundant under frequent grazing, while others soon disappear with any change of surroundings^ The natural pastures of the Gulf States are composed largely of such grasses (fig. 1) as are native to the more or less open pine woods, while along the streams and roads many foreign grasses and legumes (clovers or beggar weeds) have become thoroughly naturalized and add very materially to the value of the range. Of native forage plants not less than 3~A) species and varieties of grasses alone have been identified. Of that number, 25 yield fully 75 per cent of the grazing. Fully 90 ],)er cent of the natural grazing is aftorded by not more than 30 species. Of the 12 or 15 naturalized and widely distrib- uted species the proportion of valuable sorts is much larger, as only those which are able to thrive in this soil and climate and make places for themselves on ground already occupied by native species could become established without assistance. The best native pastures are tho.se of the prairie region of Louisiana, where the soil is fertile, the climate favorable for an abnost continuous growth, and where there are no trees to shade the ground or to appro- priate the moisture and nourishment necessary for the growth of abundant and nutritious herbage. There the FasjHiluins are the char- acteristic and most abundant grasses, carpet-grass [P. coniprcsfium}^ large water-grass {P. sods convenient, one man can plant an acre in a day. If seed is used in i)ropagating Bermuda grass the ground must be very carefully prepared, being harrowed as tine as possible. The seed should be sown in March, at the rate of about 6 pounds per acre and covered with a roller, though if sown just before a rain no other covering will be needed. As the seeds arc small they must not be covered deeply or they fail to germinate. Being expensive and unreliable, seed is seldom used. If the land is to be used for pasture only, the easiest means of securing a sod is to run shallow furrows from 2 to 4 feet apart into which sods are dropped every few feet and tramped into the soft soil. This method does very well for pastures, but leaves the ground too rough for mowing. So easily may Bermuda grass be prop- agated that good stands can be secured by scattering a dozen or more sods to the acre and then cultivating the land in corn or cotton two or three years, after which the grass will have become so well distributed that the field will need only to be plowed and harrowed once in three to five years. The yield is greatly increased, and the grass responds very quickly to an application of fertilizer, esjiecially of stable uianure, 26 When once estalilishecl, it is somewhat difficult to eradicate, and this is occasionally an objection to its general cultivation. The best method of destroying it is to plow the ground immediately after the hay is cut, leaving it as rough as possible. Plow again in November and sow to oats, and when that crop is harvested plow again and sdw thickly with cowpeas, which will smother the few plants which may have survived the oats and will leave the land in hue condition for any future croj). 'l\ui for ton, Bermuda grass has a feeding value fully equal to that of the best timothy, and many horsemen prefer it to any other hay. Broom-sedges. — The Broom- sedges are among the character- istic grasses of the Gulf States, no less than forty species and varieties being found there. All have the same general character, yielding a great amount of graz- ing and hay of fair quality if cut early, but becoming dry, hard, and woody with the development of the flowering stems, and al- most worthless in the late au- tumn. Some species are among the most common of the large grasses in the dry pine barrens, while others grow only in the damp savannahs, or act as sand binders on the island sand dunes. Under continued pasturing they give way to other grasses, and only two or three make their apjiearance again in fields which have been once cviltivated. All are perennials, but are killed by the first plowing. l>ui Blue-stem {Audropogon provincialiH) (fig. 5.). — Usually in clumps, from large, coarse root- stocks; stems 3 to (5 feet in height, with several branches, more or less purple in color; leaves long and abundant, smooth or hairy; spikes 2 to 1, digitate at the sum- mit of the branches; spikelets sparsely covered with rusty or yellowish hairs. This is the most valuable species in the group and is used more largely for hay than any other. If cut when the flowering stems are not more than half grown it makes excellent hay, but, unfortunately, it reaches that stage at a tinu) when most planters an; crowded with work in the cotton fields, and hence is usually cut too late to make forage of the best quality. It has a large cluster of tender root-leaves which cure on tlie i)lant and remain there during the winter, forming an important addition to the winter forage. While there arc other gra.sses which are better worth cultivating, the spontaneous growth of this is valuable. l'>K()()K-GiiAs.s (Audropogon glomeratm). — Most abundant <>n uuirshes :ind low ground; steins large and coarse, 2 to 6 feet iiigli, brandling much toward the sum- mit; leaves very long, rather wide, smooth, and glaucous, or hairy; spikes usually densely crowded afc the summit of the .stem, I'lO. 5. — Big Jiliie-stem (Andropogon provincialis) . 27 This is qnite common and alinndant on damp soils, and its long and abundant leaves give it considerable value lor grazing, but its stems are too coarse and woody for bay. Bkoom-sedge {Androi)ogonviroinici(s).— Stems strictly erect from an almost woody base, flattened below and loosely brancbed above; lower leaves about 1 foot long, upper leaves sborter, smooth or hairy; panicle long and loose; spikes usually in pairs and partially inclosed by the sheaths; spikelets covered with white or yellow- ish hairs, and with awns nearly four times their length. One of the most common species in old flelds and on dry soils, being usually the iirst to make its appearance in old fields and often causing great annoyance in meadows. When young and tender it is grazed to some extent, but soon becomes tough and worthless. It is one of the most troublesome weeds of lawns and meadows, and has so little value for pastures that its growth should never be encouraged. Bunch-Grass {Andropo(jon /en«-).— Stems very slender, with many widely spread- ing branches; leaves numerous, narrow, short, and smooth; spikes single, 1^ to 3 inches long, slender; spikelets slightly hairy, half as long as the bent and twisted awn. The most slender and earliest flowering species in the group. Very common in open, dry pine barrens, but the numerous stems are so wiry and the leaves so slender that it is not eaten well when other grasses are available. Johnson Grass {Jnclropogon lialepense) (fig. 4).— Perennial from long, creeping rootstocks; stems single or in clumps, erect-branching, coarse, 3 to 6 feet; leaves numerous, long and broad, panicle open and spreading; seeds large and numerous. Much like a small sorghum in general appearance. This grass has been in cultivation in this country since about 1830, and is now quite generally distributed through the Gulf States. It grows best on the rich and heavy lime soils of the black prairie region and along the creek bottoms of the yel- low-loam region, and is rarely seen in the pine-woods region near the coast. In localities where it grows well it is at the same time one of the most valuable hay grasses and the most troublesome and pestiferous weed. As a i)asture grass it has but little value, as it begins its growth late iu the season and the tops are killed by the first heavy frost in autumn. Its large and fleshy rootstocks are near the surface, and are so injured by trampling that the grass soon almost wholly disappears from the fields, though there is always enough left to restock the land when it is again brought under the plow. Its greatest value is as a hay grass, and for that purpose it can not be excelled. On land which is suited to its growth it will give at least three cuttings annually, and make a total yield of from three to five tons per acre. The hay is coarse and not attractive in appearance, but stock of all kinds eat it greedily, seeming to prefer it to any other hay. Liverymen who have used it state that it is the best hay they can find, but it is rarely fed in stables where there is a ready sale for the manure, for the seeds spread the grass wherever the manure may be used. But if the hay is mt, as it should be, before the heads appear, the manure from it can do no harm. The objections to the cultivation of Johnson grass are the rapidity with which it spreads to fields where it is not wanted, and the great difliculty in eradicating it from fields where it has become established. It will soon almost disappear when fields are pastured, but the roots remain alive and will again take possession of the field as soon as it is plowed. Instances are known where fifteen aud even twenty years of continuous pasturing have failed to produce any appreciable eft'ect on the vitality of the roots. When there are only occasional small patches of it in a field they can be destroyed by hoeing and covering with salt to the depth of half an inch, but when it covers any considerable portion of a field the only practicable method of killing it is by weekly hoeings continued from early spring until late summer. On sandy soils it can be readily killed in this manner, but on heavy clay or black lands the work is more difficult, and will require a longer time. In any case, the field should be watched constantly for plants which are almost sure to make their 28 appearance from seeds wasbed in from adjoining fields or dropped l»y birds, rattle, or passing teams. It is so difficult to eradicate that it is rarely advisable to sow it on clean land, but if it is already established on the land it is often better to encour- age it than to fight it, as a heavy crop of good hay is more profitable than is an ordinary crop of either corn or cotton. Little Blue-stem {Andropogon scoparius) (fig. 6). — Stems usually in clumps from strong roots, 2 to 4 feet high, flattened at the base, with numerous long branches, usually tinged with red or purple; lower leaves long and numerous, upper leaves short, smooth, or hairy; spikes on long and slender peduncles, single, 1 to 2 inches long, with 5 to 10 joints. Very common in dry fields and easily recognized by its purplish color and its habit of growing in bunches. Next to the Big Blue-stem this is the most abundant and valuable of the group, and furnishes a large part of the natural pasturage. It has a less abundant supply of leaves than the former, and the sterns become hard and woody sooner, so that it is less valuable for hay. .Seaside Bkoom-sedge {Andropogon marittmus). — Stems slender, coming from a crown which is often a foot or more below the surface of the sand, 1 to 2 feet tall, not branched; leaves 3 to 6 inches long, very numerous, and abruptly reflexed, sheaths over- lapping; spikes single, or sometimes in pairs, 1 to 1^ inche.* long, partly inclosed by the sheath of the sub- tending leaf. Found only on the sandy coast lands and islands, where it is a valuable species. As its roots are buried deep in the sand, it acts as an excellent sand binder, suffers but little from dry weather, and can not be pulled up by cattle. Stock appear to be very fond of it, as it i.s usually eaten down closely before other broom-sedges or other grasses are touched. Bur Grasses {Cenchrns). —A^nu\u\\s, with spreading or decumbent and much- branched stems, 1 to 3 feet high; spikes siugh', with from 5 to 25 spiny burs. There are several species of these grasses which are common on the sandy lands of the South, especially near the coast. While young the leaves are tender and are grazed closely, but after the seeds with their spine-like coverings are develojied they are avoided. Sand bur (C. fribttloidca) is the most connnou and a troublesome weedy sjiecies, while the cockspur (C. echinatua) is the largest and is often cut for hay. Crowfoot Grass (liactgloctdniKm iptinm).— Annual; stems several and branch- ing, erect or spreading, 1 to 2 feet high; leaves numerous, long, smooth; si)ikes 2 to i"), 1 to 2 inches long, digitate. A common grass in cultivated groun as a volunteer crop alter oats, melons, and other early field crops have riG. 6. — Little Blue-stem (Andropogon scoparius). 29 been harvested. It is visimlly more or less mixed with crab-grass, Mexican clover, and beggar-weed, and is highly valued as a hay plant. It comes nj) so late in the ■season that it is rarely troublesome as a weed. Most feeders prefer it to crab- grass, as it cures more easily. It appears to be more abundant iu Georgia than else- where, and in many sections of that State nearly all the hay saved for home use is from this grass, grown in cornfields. Crowfoot hay is of good quality, though the yield is seldom more than one ton per acre when the grass is grown alone; it is often double that amount when mixed with Mexican clover or beggar-weed. Feather-grass {LeptocMoa mncronata). — Annnal ; stems clustered, erect, branched from near the base, 2 to 3 feet; leaves rather numerous, long, flat, somewhat rough- ened; panicles large and widely spreading, branchesvery slender and wiry; spikclet small. Common in rich, cultivated ground, and quite showy, but the leaves are so rough and the stems so hard and woody that stock refuse it when grazing, and it has almost no value. Usually regarded as a weed. Goose-grass {Elensine indica). —Ammal; at first prostrate, but finally becoming erect ; stems much flattened, smooth, 1 to 2 feet high ; leaves numerous, long, smooth ; spikes 3 to 6, digitate, 1 to 2 or 3 inches long. A late species, which grows in cultivated ground in all parts of the South and is everywhere regarded as a troublesome weed. When sufficiently abundant to be cut for hay it makes a good crop, and as it makes its best growth late in the season it adds considerably to the fall grazing. Japanese 'Wheat-^ra.ss {Brachypodium jajwnicum) . — A short-lived perennial; stems several, spreading or upright, 2 to 3 feet lall; leaves numerous, long, nearly smooth, one-half to threc-l'ourths of an inch wide at the base; spikes 6 to 10 inches long, rather diffuse ; spikelets half an inch in length, with awns twice as long ; whole plant usually more or less tinged with purple. A winter-growing plant, first introduced into California from New Zealand, Avhich does well under the same treatment as that required for Rescue grass, being at its best in March and April. It is valuable as a part of .a mixture for newly prepared pasture lands. It has succeeded well in trial plots at all the Southern experiment stations, but has been less successful under ordinary field conditions. Kentucky Blue grass {Poa pralenns). — This grass is not the uniform success in the Gulf States which it is farther north, though in some places it is of considerable value. On low ground where the soil is dark colored and contains an abundance of lime and on seepy hillsides it sometimes gives good late fall and winter grazing, but it is useless to sow it on dry clay hills, and it nowhere makes the smooth lawns and broad meadows which it docs in more northern States. Lizard-tail Grass (Rackclochloaf/ranularis). — Annual; stems usually single, erect, much branched, 2 to 4 feet; leaves few at the base, very abundant on the stems, rather long and wide, rough; spikelets terminating the branches, 1 to 2 inches long, slender; seeds abundant. An introduced sjiecies which is found occasionally in cultivated places, though rarely abundant. As it produces an unusual amount of seed, it makes a very rich hay, though the lower part of the stem is rather hard and dry. Regarded as valu- able where it grows spontaneously, but not deemed worth cultivating. Millet {(Jha-iochloa italica). — When a crop of hay is wanted from land which has been occupied by some early crop, some variety of millet can often be used to advantage. It is a grass which requires rich land, and is exhausting to the soil; hence should not be followed by cotton or corn, though it may often be used to pre- cede clover or the seeding of a field for permanent pasture. If cut early, before the seeds begin to harden, it makes excellent hay, but if the stems are allowed to mature they become so hard and woody that they are not eaten, and the seeds, if fed in any considerable quantity, are often injurious to horses and mules. The crop sometimes fails on account of a drought soon after sowing, but if rains follow, so as to germinate the seed and give the plants a fair start, they sufter little from later droughts. There are several varieties, difl'ering principally in size, the form known 30 as rSerman millet beiiij; the largest, i^rowing from 3 to 5 feet high, and makinji the best yield on heavj' .soils; the common millet, growing from 2i to 4 feet high, being the best variety for light soils; and Hungarian millet being the smallest and most (|nickly maturing sort of the three. Seed may be sown at almost anj' time during the summer, even as late as the first of August, at the rate of from 35 to 50 pounds per acre, and the early maturing sorts will be ready for cutting in about forty days from sowing. Nimble Will ( Mnhleiiheyf/ia d'ljTu^u). — Perennial; stems numerous, nmch branched, sjjreading and ascending, very slender and wiry, 1 to 2 feet; leaves numerous, short, narrow, slightly roughened; panicle very slender, 3 to 6 inches; branches few, erect; rather densely flowered. Very common in dry, shaded places, esjjecially along fence rows, on the borders of woods, and abr)ut dwellinjrs. The stems are so tough and wiry that the grass is difficult to mow, but it often forms a considerable addition to the winter grazing. A very good pas- ture grass, but hardly worth culti- vating. Orchard Grass {DartyUs f/lomcrata) (fig. 7). — I'erennial; stems in large clumps, erect, simple, 2 to 3 feet high ; leaves very numerous, flat and broad, slightly roughened, often 18 inches in length. This is one of the most widely grown of the cultivated grasses, and in the Gulf States is one of the best for win- ter pastures, as it makes a good growth on wet and heavy clay soils with ordi- nary field treatment. It commences its growth with the first warm days of February, and if not pastured is ready to cut for hay in April, and will tlien alTord excellent grazing until checked by the summer drought. With the first autumn fains it starts a new growth of leaves, making rich fall ]>asturage, and remaining fresh and green through- out the winter. The hay made from it is of excellent quality, though its habit of growing in large clum))s is against its use as a hay grass; but it bears grazing well and recovers (juickly when cropped down. It does well when mixed with redtop, or alsiko clover, and succeeds better than almost any other grass in woodland pastures. Sandy soils arc not suited to its growth, and it can not be recommended for light and thin lands. Seed sliould be sown in August, or very early in the spring, at tlie rate of 30 to 10 pounds per acre. Panic Grasses. — The g(!nus I'anicnm contains more species than any other in the Gulf Statis, no less than 91, besides numerous varieties, having been found there, many of them being peculiar to that region. They grow in all situations, from swamps to ilry hilltojis. Some of the species are Inuinl only on wild lands, w liere they furnish more than half the grazing, while others rarely occur i'xct])t on lands which li.ive betin in vennm\, from widely spreading root- stocks; stems erect, simple, smooth, 3 to 5 feet; leaves very abundant, broad, ten- der; panicle long, its branches long and slender. Common in ditches and along the borders of marshes, where it aftbrds a large amount of good grazing. It will not endure drought and is of little value for hay. Its strong creeping rootstocks make it desirable as a soil binder. MrxRo Grass (/'aniV«Hi fl//rostsih- 7'iini dimidiatum). — Perennial by its widely creeping, flattened stems, which are much branched, and often reach a length of several feet; fruit- ing branches erect, 4 to 8 inches high ; leaves numerous, short, rather broad and olituse. Common, sandy soils near the coast. A valuable sand-binder. It is frequently u ed as a lawn grass and makes a fair turf, but its color is too light to make it as attractive as Bermuda, and the stems and leaves ari' coarser. Tall Fescue (Festuca elaiior). — Perennial; stems usually in small clumps, rather stout, smooth, erect, 2 to 3 feet ; leaves abundant, long and slender, dark green; panicle 6 to 9 inches long, loose and spreading. One of the popular introduced species, sometimes known as tall meadow fescue, Huglish blue grass, Randall grass, and by other names. It succeeds best on rather moist, rich alluvial or clay soils such as are commonly found along creek bottoms. It makes good hay, and as it remains fresh and green longer than most others, it is quite valuable for permanent winter pastures. When grown for hay it should always be mixed with other grasses on account of its habit of forming large clumps when grown alone. Redtop and alsike clover will grow well on the same kinds of soil, and the three make an excellent mixture for either meadows or permanent pastures. Tall Oat-grass {.irrhcnatlierum elalius) (lig. 11).— Perennial; stems 2 to 4 feet tall, simple; leaves not numerous; panicle similar to that of the cultivated oat, but smaller, and the spikeleta only about one-third of an inch in length. Fig. 11. — Tall Oat-grass (Arrkenatherum clatius). 38 Introduced from Europe, where it is one of the most valuable species for both hay and pasture. It is so highly prized in Europe that it has heeu plauted repeatedly in all parts of the United States, and with widely varying results. In most cases it has been more successful in the Xorth than in the South. I'rofessor Scribuer recommends it for Tennessee, and it has also been highly recommended for northern Alabama, (leorgia, and Xorth Carolina, but that seems to be about the southern limit of prolitable cultivation. Farthc^r south it is so weakened by the long summers that after a few years it is crowded out by other species. It grows best on a light and rather dry loam ; it makes its best growth early in the season, and is easily cured for hay. It does not cover the ground well wbeu sown alone, and for cither h.iy or pasture should be mixed with orchard grass, perennial rye, red clover, or some other plant which will occupy the ground more fully. Texas Blue grass (I'oa a ra dm if era). — Perennial from underground rootstocks; stems scattered, erect, rather stout, seldom branched, smooth, 18 to 24 inches ; leaves abundant, long, thick, smooth; panicle loose; spikelets covered with white woolly hairs. This is emphatically a winter-growing si)ecies. In favorable location it begins its growth in October, and from November to May furnishes an abundance of luxuriant pasturage. It matures its seed in April and from the first of June until October makes but little growth. It is difficult to propagate by seed, but can be increased rapidly by means of the suckers which are produced in great numbers. A rich, loamy soil seems best suited to its growth, but in many places where the soil has ai)peaied to be favorable its growth has been disaiipointing. Its only value is for winter jias- tures. It has given good results at the experiment stations of Missis8ii)pi, Alabama, Georgia, and Florida, but owing to the difficulty of propagation it has been very slow in coming into general cultivation. Tecsinte {Eudilwna luxurians) (fig. 12). — Annual; stems very numerous, sometimes 60 to 70 from a single seed, 6 to 12 feet tall. The stalks, leaves, and spindle resenilile Indian corn. This is the plant of which Prof. Asa Gray said, "Possibly affording an opportunity for one to make millions of blades of glass grow where none of imy account grew before." At the experiment stations of Louisiana, ilississii)pi, (ieorgia, and Florida it has given the heaviest yields of any of the forage crops grown, Georgia rei)orting 38,000 pounds of green forage per acre, Mississippi 44,000, and Louisiana the enor- moMsamonnt of over 50 tons. It needs a long season of hot weather, a lichsoil, and abundant moisture in order to succeed well, and it is useless to plant it where all these conditions can iu)t be had. It is a remarkably vigorous grower, reaching 10 to 12 feet in height, with an unusually aliundant supply of leaves and tender stems, which continiu- to grow until i feet in height it makes excellent fodder, and will produce a second cro]> fully as large as till' first. \i' lelt to grow until September or October it furnishes excellent material for tlie silo, in greater amount ])cr acre than either corn or sorghum, and there are few i)lants which are its equal for soiling purposes. Its leaves are similar to those of sorghum, but much longer, and the stalks contain from 8 to 10 per cent of sugar. Its value for feeding and soiling is a))parent from the fact that the entire crop of 50 tons jier acre grown at the Louisiana station was sold to local dairymen at the rate of $2 per ton while standing in the field. Its season of growth is so long that it .seldom matures seed north of latitude '.W\ but it has ri]iened well at Ihe Louisiana and I'lorida stations. The seed, I to 5 jtounds per acre, should bo ])lanted in hills 4 to 5 feet ajiart each way, aliout cotton-jdanting time, and the crop cultivated like corn. The greater distance should bo gi\-cn on the richer soils. Timothy ( I'lilrnm jiratoiar). — K'arely successful in .iiiy part of the (Jnlf States. It makes one good (■iitting in the sjjring after it is sown, but the long summer weakens the l)ulb-like roots so that but few jdants survive until tiie next year. Toothache-grass {Campidosua aromal'n-nn). — Perennial from stout rootstocks; stems siugh- or clustered, erect, uiibranched; leaves long, narrow, smooth; sjukes 39 X '■ '■•■../fk'V'W.I,-'.'

Tlie rootstoeks, wlien mature, have a pungent, aromatic taste, and chewing tlicni is said to be a remedy for toothache. The whole plant is more or less aromatic, and is rarely eaten by stock Velvet-grass ( //o/(»« lanatiis). — Perennial; otten in large clumps; stems erect, not branched, 1 to 2 feet high; leaves very numerous, long, and wide; panicle 2 to 3 inches long, erect, compact, often tinged with ])urple; wliole plant clothed with soft white hairs, which give it a very striking a])i)carancc. This is one of the European grasses which has boen higlily recommended and extensively planted, but has rarely been successful iu the Gulf States. It sometimes remains (airly permanent on thin soils wliere it is not crowded by other sorts, but is never eaten well by stock. On richer and nioister soil it is often seriously atfected by one of the same rusts which attacks oats. It should be sown only when in mix- tures and (m thin soils. Water-grasses { PaspaJums).— The Paspalums rank next to the panic grasses in imiiortancc and in number of species in the native pastures, 3G being found in the South. Like the panic grasses, very few are of much value for hay. The group fur- nishes several of the best past ure grasses, however, and some of these are well worth cultivating. Most of the species ])refer a moist soil, and though they are often found on soils wliich arc (luite sandy, they are rare on dry clay hills. Most of them are perennial, and several bear cold so well that they are of considerable importance in winter pastures. Caui'KT-(;rass (Paspalnm covipreifum). — Perennial; stems erect or decumbent, extensively creeping and rooting at the Joints, upright stems (5 to 18 inches; leaves very numerous, short, obtuse, smooth; peduncles long and slender, terminated by 2 to 4 very slender spikes 1 to 2 inches long, similar to those of crab-grass. Tliis is ai)parently indigenous along the coast, and is slowly spreading northward, being now somewhat conunou iu central Mississippi and Alabama. It is undoubt- edly the best pasture grass we have tor sandy soils, and it will bear more hard tramp- ling and close grazing than will any other species. On heavy soils it is often crowded out by Hirmuda and other s])eeies, but on light soils of oven moderate fertility it will soon cover the ground, to the exclusion of all others. It is a grass which soon comes iu when sandy soils are jtiisturcd closely aud will ch(dagated by mowing when the seed is ripe, and scattering the hay over the liebl where the grass is wanted. Even if but few plants should ai)pear the tirst year, the seeds will soon be spread by stock so as to cover the entire lield. It bears heavy frost without injury, and so affords consid- erable grazing during the entire winter. It is often used as a lawn grass on soils too light and sandy for Bermuda, and is excellent for that purpose, though its rather light color uuikes it less attractive than a grass having a richer green. lloNKV Dkw (I'aspdiiitn plicatiihim). — i'erennial, though often growing as an annual ; stems, many from a single root, nnnh branched, spreailing or erect, smooth, 2 to 3 feet; leaves nruuerous, rather long. n«'arly smooth; spikes 1 to 10, spreading, 2 to 3 inches lest growth. It seldom grows sulliciently large to make a good yield of hay, but is an excellent pasture plant, and should always be sown with redtop on 43 the damp places in a permanent pasture. Sow 6 pounds of seed per acre in Septem- ber or March. Artichoke (//e/irt»i^ftH8 /h?)c/-os«s).— Perennial, by underground tul)er8; stems erect, 5 to 8 feet ; leaves and dowers much like those of the ordinary suntiower, but smaller. One of th 10(» liushels i)er acre. The tubers are ]ilanted in early spring, 12 to 1.^ inches ajiart in rows 3 to 4 feet apart, and Fig. 15.— Canada field i»ea (IHsum arvente). 45 the only cultivation needed is to keep down grass and weeds. The tubers mature in October and November, aud are easily rooted out by the hogs. Of little value on heavj' soils. Cowpea {Vigna catjavr/). — Well-known annual of unknown origin; cultivated throughout the South for more than one hundred years. kSonie varieties mature within sixty days from planting, while others will continue to grow until killed by frost. In planting it is better to select varieties which will mature a good x)art of the seed before time for frost. The heavier yield is secured by planting in drills and cultivating, but Avhen seed is cheap and labor scarce a less expensive crop can be made by sowing broadcast. The better farmers always plant peas between the rows of corn at the last plowing, and the crop isone which can be grown with profit during any two months of warm weather when the land would otherwise be idle. Crimson Clover {Trifoliiimincarnatum). — Anniial; stems erect, somewhat branch- ing, 1 to 2 feet ; leaves nu- merous, oboA^ate, rather large; tlowers bright crim- son, in long spikes. Introduced from Europe ; a valuable plant in nearly all of the country east of the Al- legheny Mountains from New Jersey to Georgia, but has rarely succeeded well in any of the Gulf States. Seed should be sown in September or October at the rate of 20 pounds per acre, and where it grows well it can be grazed during the winter or cut for hay in the spring before the seed begins to mature. The plant has not proved gener- ally valuable west of the Al- leghanies, and in the South has rarely made a crop of any value, as the plants usually die during early winter. The matured plant is dangerous for feed as the stiff hairs on the calyx form balls in the stomachs of animals and often cause death. Perennial; much like winter vetch in Fig. 16. — Cassava (Manihot aipi). Flat Pea {Latliyrua sylvestris wagneri). appearance. This was introduced from Europe a few years ago, and extravagant claims were made for its luxuriant growth on the hardest and most sterile soils. It has been tested repeatedly at each of the Southern experiment statious and by hundreds of farmers, but has been uniformly disappointing. Its growth the first year from seed is rarely as much as 12 inehes, and it requires the best of care to make it survive the summer. Older plants are more hardy and vigorous, but fail to hold the ground against native grasses and weeds, and soon disappear. Florida Beggar-weed {Desmodium tortuosum). — Annual; stems erect, branching, 4 to 7 feet; leatiets 3, rhombic or elliptical, tomentose beneath, rough above; flowers small; legumes 1 to 1^ inches long, 3 to 6 jointed, rough-hairy. Very common on sandy soils in Florida, and extending into South Georgia and Alabama; often planted and becoming naturalized along the coast farther west. 46 This is tlie best leguminous forage plaut which has been found for light sandy soils, and it makes a vigorous growth on soils too light for most other crops. Its primi- pal use is as a grazing plaut, stock of all kinds grazing it freely and fattening rap- idly where tlie phmt is abundant. As it does not begin its gmwth until late in tlit^ spring and is killed by moderate frosts, it is valuable only during the summer and fall. It often grows as a volunteer with crab-grass and crowfoot on cultivated lands, and is then cut for hay. When used for hay, it should be cut when only 2 or 3 feet high, as the stems become hard and woody as the plant grows older. Besides its use as a hay and grazing ])lant it is a valuable fertilizing crop, and the seed is often scattered in corn tields at their lust cultivation. When sown for hay, from six to eight pounds of seed are used per acre, and after land has once been seeded it seldom needs reseeding, though the plant never becomes a troublesome weed. Several other species of Desmoditim are found, usually in dry woodlands, through- out the entire region. Among the more common of these are D. acuminatum, vudi- florum, paucijiorum, and riridifiorum. All are eaten fairly well and add considerably to the woodland pastures, but are rarely abundant. Groundnut (Jpios tuherosa). — Perennial ; stems climbing; leaflets .5 to 7, ovate or ovate-lanceolate; brownish-purple flowers in axillary racemes. Common in wooded swamps from Mississippi to Florida and northward. Eaten by all kinds of stock, hogs being very fond of the small tubers on the roots. Hog Peanut (Amphicarpwa monoica). — Peren- nial; climbing; leaflets 3; flowers of two kinds — those on the stems in drooping racemes and sterile, those at the base fertile, fruiting under- ground. Occasional in rich, damp woods from Mississippi to Florida and northward. The vines are eaten by cattle, and hogs are fond of the underground nuts. Horse Beau {Faha vulgaris). — Annual; stems erect, 2 to 3 feet; leaflets 3, oval, smooth and glaucous; flowers in small axillary clusters; pods 2 to 4 inches long. Highly prized in Europe, but not successful here, as the plants are usually destroyed by blight at about the time they begin to bloom. Jack Bean (Canavalia ensiformis). — Annual; stems erect, bushy, rather stout; leaflets 3, large; flowers few, in dense axillary racemes; pods 3 to () in a cluster, a foot or more in length ; seeds large, white. This came into notice about 1890, and since then has been planted in many places. The growth of the plaut is all that could Ije asked, and the yield of bc^ans is from 30 to .")() l)ush(;ls per acre; but, unfortnnately, iieitLer the beans nor tli(^ jdants are eaten well. At the Mississippi station the beans were fed in many ways — dry, soaked, ground into meal, and cooked — but neither horses, mules, cattle, nor hogs would eat them. Japan Clover (Lespedeza striata) (fig. 17). — Annual; stem branching, slender and wiry, 3 to 24 inches; leaves very nunnTous, small; flowers small, in axillary clusters. This may be classed among the most valuable leguminous hay and pasture ]>lants of the (iulf .States. It is a native of .lajian, wliicli was introduc<>(l into tliis country about 1830, and is now thoroughly naturalized over the whole country south of the Ohio Kiver. It grows on all soils, liut does best on good loams containing a fair Fig. 17.— Japan clover (Lespedeza striata). 47 amoujit of lime. It will also grow on lianl, dry clay, and even wLere the soil is quite sandy. On thin soils its growth is very flat and spreading, while on better soil it becomes erect, and is often 2 feet in height. It endures heat and drought without injury, and stock eat it greedily. It never causes bloating, but occasionally has a slight salivating effect on horses, though that appears to occur in only a few- localities. It starts late in the spring, but from May until after heavy frost it gives the best of grazing, and should be in every pasture. Although mostly used for grazing it is a valuable hay plant, making a good yield of from 11 to 2 tons per acre. When wanted for hay, it should be sown in early spring, at the rate of one-half bushel per acre, or it mayT)e sown with oats in the fall, as it makes but little growth before the oats are harvested. For pastures it is necessary only to scarify the sur- face of the ground with a disk harrow, and it will often grow well without any previous preparation of the soil. There are a number of native species of lespedeza which are quite common in dry, open lands throughout the South, and although all are grazed, they are not worth cultivating. Kidney Bean (Phaseohts diccrsifo- lius). — Annual; stems prostrate or trail- ing, slender, 2 to 4 fe6t ; leaflets 3, oval or 2 to 3 lobed ; flowers purple, on long pe- duncles ; pods long and slender. Common on dry, sandy soil, affording some summer and fall grazing, but hardly worth cultivating. Three other species of the same genus are quite widely distributed throughout the South, but are not sufficiently abun- dant to be of much importance. Mexican Clover {liichardsonia sca- hra). — Annual; stems branching, diffuse 2 to 4 feet; leaves numerous, oval, rough; flowers nearly white, in small heads. This is not a true clover, but takes its name from its habit of growth, which is much like that of red clover. It is a na- tive of Mexico and Central America, but has become thoroughly naturalized along the Gulf coast, and is found occasionally as far north as central Mississippi and Georgia. A sandy soil seems essential to its vigorous growth in cultivated fields after other crops have been laid by. Where this and crab-grass grow together on well-fertilized soils the yield of hay is often two tons per acre, and costs nothing but the cutting. Feeders are somewhat divided as to its value, some claiming that it makes hay of fine quality, while others declare it to be worthless. Chemical analysis of the hay indicates that it is nearly or quite as rich a food as red clovei", and it is certain that many animals keep in good condition through the winter with no other feed. It has but little value for grazing. Milk Pea (Gnlactia (jJabella). — Annual ; stems prostrate, 2 to 3 feet long, very slen- der ; leaflets 3, rather rigid, 1 inch long ; flowers large, reddish purple, 3 to 6 in a cluster. Common on dry pine barrens and eaten well, but scarcely worth cultivating. Eight or ten other species of Galactia are more or less abundant, usually in dry woods. All are eaten freely, but their growth is too thin and scattering to make them of much value. Fig. 18. — Peanut (Arachis hypogea). 48 Peanut (Arachis hypogea) (tig. 18). — Of some value for hay, and cultivated for hog pastures iu all parts of the South. There are two very distinct types in culti- vation, the "common" and the "Spanish." The former is the one which produces the peanut of commerce. The plant grows as straggling as a potato, and the nuts are produced on long peduncles and often (juite scattered. This is seldom used for hay, though often grown for hogs. The Spanish variety is a smaller, more compact, and erect plant, which produces an immense number of very small nuts clustered closely at its base. This variety is growing in favor for hay, as the plant with its closely adhering nuts is easily pulled up. The yield is from 1 to 2 tons per acre. Fio. 19. — Soy Bean {Glycine hispida). and as nearly half the weight is in the nuts, the hay is richer in protein than any other in common use. Either variety makes tine fall pasturage for hogs, and as the hogs do the harvesting, jteanuts furnish tin- chca])est food for the season. Prickly Comfrey {Symphiilitm. dsjxrrimiim). — rerenuial; stem erect, coarse, 2 to 4 feet; leaves very large and abundant, rough. A very rank-'growing jtlant which has been highly recommended for forage, espec- ially for soiling. It is propagated by cuttings of the roots, which are planted about 1« inches apart in each direction and which continue to produce heavy crops of leaves for several years. Cattle do not cat tlie leaves readily until they become 49 accnstomed to them, and there are other jilants which are more profitable in the South. Ramie {Boehmeria nivea). — Perennial; stem erect, coarse, 2 to 4 feet; leaves numerons, large; flowers very small and inconspicuous, in axillary clusters. Although this is ordinarily cultivated as a fiber plant, it is grazed well by cattle and is an excellent crojt for soiling. On rich soil it will give from three to six cut- tings of the stems from 2 to 4 feet in height, and if cut before becoming mature they are so tender that the entire stalk is eaten. It is profitable only on rich soil, and does much better near the coast than farther north, as it needs a long season with abundant rains. Red Clover {Trifolinm prateiise). — Red clover is becoming more popular each year, and is now quite a common crop in the black prairie region and in other sec- tions where the soils contain a fair amount of lime. It requires a soil which is rich and in fairly good condition to insure a "catch " of the seed. On many soils where it makes a good start and yields two or three cuttings it soon becomes overrun with other plants and is choked out. It is the best of the family to occupy a good soil two or three years, but is of little value on poor soils. Seed should be sown in September at the rate of 10 to 12 pounds per acre, and it will then give a heavy cutting the following May. It succeeds best in the South when sown with no nurse cro]). Sedges (Carues).— Very similar to the true grasses in general aj)pearance, but with the stems 3-angled and the leaves 3-rauked, while among the true grasses the stems are nearly round and the leaves are 2-ranked. Usually on soils which are too wet and heavy for most of the true grasses, very common in swamps and tide marshes; nearly all are grazed when yoang, but as they approach maturity most species become so tough and tasteless that they are not touched by stock. The hay made from them is of poor quality, and one of the species is worth oultivating. Soy Bean {Chjcine hispida) (fig. 19). — Annual; stem stout, erect, branching but little, 2 to 4 feet; leaflets, 3; flowers in axillary clusters; pods short, 2 to 4 seeded; whole plant rough-hairy. One of the staple crops of Japan, which attracted little attention in this country until about ten years ago, but is now becoming quite common. The crop is culti- vated like corn, the seed being i)lanted in drills at the rate of half a bushel per acre. The stems alone are too coarse to make good hay, but are covered with such a dense growth of leaves and are so prolific in fruit that the hay is prized highly, especially for milch cows and for fattening animals. The yield of green forage is very heavy when grown on good soil, and the yield of beans is from 20 to 30 bushels per acre. Those who have had most experience with this crop find that the best way to handle it is to cut or pull the plants when the first pods begin to open, and thrash as soon as dry enough. In this way the coarse stalks are so broken in pieces and mixed with the leaves and immature fruit that nearly all will be eaten. It is doubtless the best of the legumes for the silo, as it can be more easily handled for the cutter than can plants like clover or cowpeas. There are a number of varieties, diftering mainly in the time of ripening and the color of the seeds. Spurred Butterfly Pea {( 'eniroaema virfiiniana). — Perennial; stems twining, 3 to 5 feet; leaflets, 3; flowers on short axillary peduncles, blue or purple, li inches long; legumes, 4 to 6 inches long. Common on dry soil in woods; eaten well, and might be worth planting in wood- land ])asture8. St. John's Bread; Carob Bean (Ceratonia fiiliqiia). — A tree which is grown rather commonly in Florida, and occasionally farther west. It is valued for its sweet, flesh j^ pods, which are very rich in sugar, and so are good feed for fattening stock. Sulla (Hedysarnm coronarium). — Perennial; stem erect, branched, 4 to 6 feet; leaves very numerous, pinnate; flowers in large showy clusters. 5720— No. 15 4 50 A very (leep-rootiDg plaut wliicli grows best on a well-drained soil. It makes a heavy yield in early spring, but is so tender that it can not be retouimended except in Florida, as the plants are killed by frosts. "When sown in the fall it makes an enormous growth during the winter, which is slightly injured by very severe frosts without being killed. Scarcely hardy enough for a winter crop, and yet not sui cessful as a summer one."' Sweet Clover (Melilotus alba). — Biennial; stems erect, widely branched, 3 to 5 feet; leaves abundant, tri-foliate; leaflets elliptical; flowers white, in slender spikes. Common where the soil is rich in lime. Even on the white, rotten lime-stone hills in the black prairie region, where no other plants can grow, this makes a good yield. Its growth is much like that of a coarse alfalfa, but it will grow well on a much poorer soil and on one which is in poor mechanical condition i)rovided it has an abundance of lime. It may be sown with Johnson grass, when it will make one cutting before the grass has much growth, and the later cuttings are heavier than when either plant is grown alone. It is an excellent pasture plant, beginning its growth in early spring. Cattle not accustomed to it do not always eat it readily at first, but if turned into the pastures before other vegetation furnishes much grazing they soon acquire a taste for it. The roots are very large and deep, and as they decay at the end of the second season they are fine fertilizers. Seed may be sown in either October or February. Usually but one cutting of hay can be made the first year, but the second season it will make three good cuttings. Although a biennial, a few plants will produce seed the first year and a few will live three years, so that land needs to be seeded but once to secure continuous occupancy by melilotus. Sw^eet Potato {Convolvulus edulis). — The ranker-growing and coarser varieties of sweet potatoes are used largely for hog pastures, as the crop is one which can be grown with very little expense, and the harvesting is done by the hogs. The yield is often 200 bushels per acre, and the crop is one of the best and the cheapest that can be grown on sandy soil. The vines are sometimes saved for hay, but are hard to cure. Velvet Bean (Mucnna uiilis). — Annual ; climbing stems sometimes 50 feet in length ; leaflets 3, large; pods numerous, 2 to 3 inches long, each containing 3 or 4 large oval beans. A newly introduced plant which has not been extensively tested, but which has been highly recommended by the experiment stations of Louisiana and Florida. Vetches. — Six species of vetch are native to the Gulf States, two or three of whij;eHs).— Uncertain and unreliable in its growth, some- times covering the ground with a thick mat of vigorons plants, and then often dis- appearing for several seasons. A good grazing plant for cattle, but thought by M some to be injurious to horses and mules. ■ Yellow Lupine {Litpinus 7h/<;hs).— Annual ; stem erect, stout, 2 to 3 feet; leaves numerous, palmately compound, large; flowers in large and showy terminal clusters. This plant, unlike most other legumes, grows best on a soil containing but little lime, and so is especially valuable for the soils aloug the coast and ior much of the pine-woods region. It affords good grazing, and the hay is valued as fully equal to that from red clover. The seed is high priced, and as from 75 to 100 pounds are required per acre the plant is not yet common, but is well wi;rth planting experi- mentally on soils poor in lime. In Europe it is used successfully for renovating worn out sandy soils. INDEX Page.

There are few similar areas where the natural conditions at the time of first occupation were so favorable to the rapid development of the stock industry. The country lying between the Rio Grande and the thirty-fifth parallel of latitude and between the ninety-eighth and one hundred and fifth meridians is a successiou of prairies and plains, rising gradually by successive broad steps from the coast to the table- land of the Staked Plains at an altitude of about 4,000 feet. This series of plains is broken by mountains only in the southern and south- western portion and west of the Pecos River beyond their borders. Of the 11>0,000 square miles embraced in this territory probably not more than 10 per cent is adapted to successful agriculture under present methods, although one-fifth or one-third of it is capable of conversion into farm lands, and doubtless will be so converted at some future period, when the farmer is able to preserve the abundant natural resources of the region and profit thereby. At the time of the earliest settlement this Texas territory was for the most part treeless, excepting along the streams and where the two bodies of "cross timbers" entered it ou the north and where a wedge- shaped tongue of the east Texan timber belt penetrates the prairies south of Austin and San Antonio. The land was well covered with grasses, and was grazed by immense herds of buffalo, wild horses, and great numbers of deer and antelope. Among stockmen the tendency has been to look upon these wild lands as never having been grazed until cattle and sheep were intro- duced, but there is abundant evidence to show that they have always been closely pastured. The early explorers differed in their accounts of the luxuriance of the grass vegetation, but the differences were no greater than can be accounted for by local or temporary causes, such as variable seasonal rainfall, which occur at the present day. It is estimated that the southern buffalo herd contained not less than four million head.* This vast number grazed in the district south of the Platte River, retiring to the plains of western Texas and the Indian Territory at the approach of winter, and turning northward again in *Smithson. Report Natiastures provided with water, in each of which the cattle would be allowed to run for not more than two or three mouths at a time and then be transferred to another. In this way the succes sion of grasses which normally occurs in nature can be fostered and improved. Let us suppose a range of 100,000 acres in extcMit divided into ten pastures of 10,000 acres each. At the average carrying capac- ity for the State this body of land will produce forage enough to iSus- taiu 10,000 stock cattle throughout the year. These divided up into their various classes — beef steers, two-year olds, and yearlings, cows and calves — could be held three months in one pasture and then trans- ferred to another which had been kept free from stock during that ength of time. A rest of two or three months during the growing- season in early spring would enable the early grasses to ripen and shed their seeds, thus perpetuating the early species. After the seed had fallen, the cattle could be turned on the grass for two or three months and again transferred to a fresh pasture. In the same way autumn and winter pastures can be secured. Several stockmen who have employed this method on a large scale for a number of years say that their ranges are continually improving, in marked contrast to the dete- rioration that had occurred through bad treatment of neighboring properties where the old methods were practiced. It is also claimed that pasture land thus treated will carry more head of cattle through the year and bring them out in better condition than where the herd has access at all seasons of the year to all portions of the range. Where winter feeding is practiced in connection with alternation of pastures, the very best results may be obtained at the least cost, and the owner will find that with judicious care the value of his prop- erty will constantly increase and the annual i)roflt as represented by the increased number of marketable steers will more than compensate for the cost and labor of changing cattle from oue pasture to another. ADDITIONAL AIDS TO RANGE IMPROVEMENT. In addition to the methods of improving the range by cultivating the surface of tlie grouiul, raising native grasses, plowing occasional furrows to arrest the wind-borno seeds, and scattering the seeds of native and introduced forage plants on the unbroken sdd, the cultiva- tion of the ranker and buUvier forage crops should be encouraged. On aliiu)8t every ranch there are strips of valley lands, or often exten- sive meadows, which are naturally well watered, or Avhich are so situ- ated that they may be inigated from artificial tanks. These lands should be put into cultivation. The rancher is often loath to incur the expense and trouble necessary to gi-ow and cure a patch of sorghum or of some hay grass, but the i)ossessi(m of a sulluiient amount of 23 cured fodder or hay will insure liiui against excessive loss as the result of drought or of the rotting of the natural pasture grasses through autumnal or winter rains. STACK STLAGE. Tlie practice of making good hay from alfalfa, cowpeas, Johnson grass, the sorghums, and other coarse or succulent plants is often attended with much difficulty, and the product varies in qnality and value according to treatment. Successful hay making requires con- siderable experience, besides taking time and a large force of laborers, so that the expense of preparing a cured crop often amounts to very nearly its feeding value. The fact that it recjuires a number of men will sometimes prevent cattle owners from trying to put up any hay. The desirability of having a quantity of green, or at least succulent, feed during times of drought and during late winter and early spring months is well recognized. In the farmiug districts that want may be supi)lied by the cultivation of soiling crops, root crops, and by putting up silage, the latter prepared in strongly built silos. The cost of building a silo precludes its use by the majority of farmers and stock owners, especially in the more sparsely settled districts and in the arid and semiarid portions of the Southwest, where lumber and labor are high priced. Fodder and hay are very desirable, but they must be cheap and easily prepared else they will not be used. Stack silage or oi)en-air silage is extensively used in portions of Australia, South Africa, and northwest India, where the general conditions as to fer- tility of the soil, rainfall, and climate are about the same as in Texas and the Southwest. It is claimed that the value of stack silage was first discovered about 1867, when a New Zealand farmei- whose haying operations were inter- rupted by heavy rains, raked the green, freshly cut grass into a great pile, his idea being to save the, as he supposed, rotten mass for fer- tilizing purposes during the coming season. Instead of the grass rot- ting a fermentation took place and the product was eaten greedily by stock which were turned into the field during the winter. Whatever may be the source of the practice, the fact remains that stack silage finds a very wide use in hot countries among stock farmers and men whose means do not permit them to j)urchase silage cutters and build silos. The theory of making silage is to pack the green forage into a com- pact mass, thus preventing the entrance of air into the material. The green mass undergoes a sufficient fermentation to partially cook and preserve it. In building a silo the walls are constructed of heavy tim- bers, braced and covered both inside and out with sheathing, tar paper, and matched boards, made as nearly as possible air-tight, for it has been found that wherever air penetrates into the mass or the fermen- tation is carried too far the silage becomes moldy, producing an indi- 24 gestible mass. Where air lias free access during fermentation, the process will be carried too far, but where the amount of air is limited the fermentation is only carried to a certain point and the palatability of the food is improved. It has been found that a silo and fodder- cutting machines to chaff the stems into small pieces are entirely unnecessary in dry climates. Instead, the green grass or green fodder is raked and stacked as soon as cut. Then, when the pile has been carried up as high as convenient, weights are put on the top and the sides are trimmed down i)erpendicular with a hay knife. This method produces a sweet silage, which has very nearly the same feeding value as silage prepared at greater cost in built silos. Mr. Fred Koehler, of Bee County, Tex., has used stack silage made of sorghum, and considers it, when fed in connection with cotton- seed meal and hulls, the cheapest and best fattening material for top- ping oft" beef steers for the market. He builds a sort of paling fence, using 4- or 6-inch fence boards in 10 to 16 feet lengths, woven together with heavy galvanized fencing wire, leaving about a 2-inch space between the boards. The length of this fence can be accommodated to the diameter of the stack which it is desired to make. When the sorghum is ready to cut, which is about the time that the seeds are commencing to harden, one of these paling fences is set up in a circle, varying from 12 to 20 feet or more in diameter. Then using horse rakes, loaders, and stackers, the freshly cut or slightly wilted sorghum is fed over the tops of the boards into tliis pen, and the process is con- tinued until the pen is tilled. During the lilling, the fodder is stamped down around the edges so as to leave no air s])aces. When the pen is filled to the top a layer of straw is added and built up to a peak to shed rain. On tliis is piled dirt or stones or bags of earth to the depth of 2 or 3 feet, in order that the pressure shall range from 125 to 200 pounds to the square foot. Pressure may also be applied by means of a Span- ish windlass or by levers. The palings remain in place until the stack has settled and compacted sufficiently to stand alone, when they may be removed and set up elsewhere and the process repeated. It has been found that by applying the pressure at the right time one may readily control the fermentation and produce either sour or sweet silage as desired. Thus, if the fermentation is not allowed to proceed above 130° F., if the stacks are weighted when this temi)era- ture is reached sour silage is produced. If the fermentation is allowed to go on until the temperature rises to between 150° and 165° F. before the stacks are weighted, the mass Avill often become highly carbonized, appealing dark brown, or almost as black as charcoal, but the silage is sweet and relished by cattle. Sour silage is considered more satisfac- tory for dairy purposes than sweet silage. The ])ossibility of i)reserving largo <|uantities of the coarser forage- plants by this method will undoubtedly prove valuable for extensive districts in the arid grazing regions. It will not, however, be adapt- 25 able to humid climates. Wherever the rainfall amounts to more than 25 or 30 inches, or where the air is moist through a large i)art of the year, silos will have to be built. The manufacture of stack silage opens great possibilities and will enable stockmen to increase the num- ber of cattle upon the range. If palings are not available for conlining the silage and making the sides perpendicular, the stack may be built up in the same way as a haystack. At the close of the operation, after the forage is well settled and compacted, the looser outside por- tions may be trimmed off perpendicular with a hay knife and piled on top of the stack as a thatch. Corn can not be depended on as a forage plant in semiarid regions. The best crops, and those which seldom fail, are sorghum, milo maize, Kafir corn, and Johnson grass, the latter for the richer bottom lands. Of the first three forage crops, from 10 to 20 tons of the green forage may be secured per acre, and at least two cuttings, from 4 to 8 tons each, of the Johnson grass. Two crops of sorghum may often be grown on the same land in one season. Fodder made from the sorghums is rather difficult to cure, or, to speak more properly, is difticult to handle after curing, on account of its bulk and the harshness of the leaves and stalks. Moreover, in the dry climate of the Southwest much of the best part of the fodder and leaves is lost in the process of handling, because becoming so dry and brittle. The stalks are also tougher than corn- stalks, and there is more waste in feeding. In the case of Johnson grass there are grave objections to its use for hay on a large scale, because of its weedy character when introduced into farm lands. The territory where Johnson grass is the most valu- able hay grass, comprises the red prairie region, which includes the headwaters of the principal streams that in their lower courses flow through the rich farming lauds of eastern and southern Texas. The seeds of this grass are liable to be washed down from the headwaters in time of flood, inoculating new fields with this, to the cotton farmer, undesirable pest. If the Johnson grass is tnrned into stack silage instead of being made into hay, the danger of spreading a bad weed will be obviated, because the germinating power of whatever seeds may be in the stack will be destroyed by the heat generated in the course of fermentation. The principle of stack silage is not by any means a new one. The methods of curing clover and alfalfa in cocks are practically the same, as are also those of curing green corn and sorghum in shocks. In such cases fermentation of the ])artially wilted substance takes place, the difference being that the fodder in shocks ferments at a much lower tem- perature than in stacks. Thus silage can be made at very much less expense than hay. Enough has been done by stockmen and feeders to show that stack silage is not an experiment, but is entirely practical. It is probable that much may be added to our knowledge, especially in regard to such details as the best height and width of the stacks and 2(5 ill regard to the time of maturity of the crop from TV^liich tlie silage ia to be made. It will also liave to be. determined wlietlier the legumi- nous forage crops, such as alfalfa, soy beans, and cowpeas, can be put up in the same manner or whether they can be added in alternate layers in the stack, as is often done in the manufocture of silage in air-tight silos. The principal caution in putting up such stacks will be to see that no large cavities are left in the material, for wherever too much air has access the fermentation is liable to be carried to the putrefactive stage, following which molds will grow and render it very injurious, if not actually poisonous. These precautions are less necessary in the case of Johnson grass or broadcast sorghum, because the mass will be much more compact. HAY. In addition to putting up considerable quantities of stack silage, it is advisable that cattle owners provide hay, if a suj^ply can be secured irom natural or artificial meadows on the ranch. Very often stockmen who have not made this provision have to buy feed during winter, especially during the heavy snowstorms in the spring before the new grass has started and after the prairie grasses have either all been eaten off or have been rotted by rains or melting snows. In such cases hay often sells from $10 to $20 per ton and is hard to get in time to pre- vent losses. Prairie hay can be put up at the cost of usually not more than $1 to $2 per ton, using modern machinery and appliances. With the large number of kinds of hay grasses to choose from, any rancher who has fairly good laud has no excuse for not putting up enough hay to carry his stock at least through the severer storms of the winter. WATER. Another precaution that must be taken, if the stock ranges are to be restored to anything like their former value, is that water must be pro- vided in .sufficient amount so that cattle will not have to travel long distances for it in times of severe drought. Nearly the entire western portion of Texas is underlaid by artesian waters ranging from 150 to 1,500 feet below the surface. Wherever the drainage slopes are not too precipitous, artificial tanks may be formed across the draws by building dams, and if the bottom of the tank is carried down to hard- pan, or is puddled before being filled, a supply sullicient to last through the dry season may be secured at small expense. Such tanks, or wells, either artesian, or where the water is lifted by windmill ]tumps, should be provided at least every 4 miles over the range, so that cattle will never have to travel more than a couple of miles to water. Where the wells, water holes, or tanks are 8, 10, or more miles apart, as they very frequently are on some of the western ranges, cattle greatly overstock tlie range in the vicinity of the water, especially during midsummer, while tlie back country is thickly covered with jiood feed. Thus a 27 portion of the range will be overstocked while another j)ortion will be nnderi^razed. In the one case the grasses are eaten down and trampled for a few miles back from the water so that it may reqnire several good seasons to undo the injury done in one bad year. In addition, the forage on the large area back from the water is entirely lost through not being grazed. The cost of constructing dams or providing wind- mills will often be but a small percentage of the loss incurred when no water is provided. It has been often observed that the period of How of the rivers in countries wliich have been overgrazed is very much less than it was formerly. This is because the tramjding of the herds has compacted the soil, and also because the waters are not retarded from running off the surface as they would be when the land is covered with a thick coating of grasses. Hence the drainage of the surplus water takes place in a very much shorter time. There are many streams and springs which in former years afforded a continuous supply throughout the dry season, which now only run during or immediately succeeding periods of abundant rainfall. Thus less dei)endence is to be placed upon the streams as a source of stock water. New artificial sources of supply must be provided. GRAZING REGIONS IN TEXAS AND NBV7 MEXICO. Texas may be divided into seven or eight well-defined agricultural jtrovinces, each differing from the others in the general character of the soil and amount of rainlall. These differences of soil are mainly due to difference in geological formation, while the causes of the climatic variation are the natural phenomena which govern continental condi- tions, such as altitude, proximity to the Gulf, and presence or absence of vegetation. The areas or belts where soils and natural conditions are alike, or have only casual differences, are usually marked by the growth of certain plants, which form a characteristic, though not always the most prominent feature, in the grass flora. The region under dis- cussion may well be divided along these lines and treated by areas.* These are: The Coastal Prairies, bounded by a line drawn parallel with the coast about 70 miles back from the Gulf. The Cactus Plains, which include all of the region between the Colorado and Rio Grande from the border of the coastal prairies to the " rim " of hills that breaks to the northward from San Antonio, just below the thirtieth parallel of latitude. The Middle Plain, a low table-land, rather mountainous, extending from the southern "rim" to the Concho, and from the Colorado to the Pecos. This is the Edwards Plain of the geologists. The Granite Region, occupying a very limited area in the center of the State between the central plain and the red prairies. * From data supplied by Prof. Robert T. Hill, of the United States Geological Survey. 28 The Red Prairies, extending- from the Concho to the Red River, bounded on the east by the black lands and on the west by the Llano Estacado, The Staked Plains, or Llano Estacado, a high level table-land which extends into New Mexico, containing the sources of all the rivers flow- ing to the eastward. The Pecos Valley, an elevated valley which has the same soils as the red prairies, but a much smaller rainfall, so that the conditions are arid. Before the ranges were overgrazed the grasses of the red prairies were largely blue stems or sage grasses {Andropogon), often as high as a horse's back. After pasturing and subsequent to the trampling and hardening of the soil, the dog grasses or needle grasses {Aristlda) took the whole country. After further overstocking and trampling, the needle grasses were driven out and the mesquite grasses {lUlaria and Bulbilis) became the most prominent species. The occurrence of any one of these as the dominant or most conspicuous grass is to some extent an index of the state of the land and of what stage in over- stocking and deterioration has been reached. There is often a succession of dominant grasses in nature through natural causes, but never to so marked an extent as on the cattle ranges during the process of deterioration from overgrazing. Thus, the grasses in any given valley are liable to change in a long series of years through destruction by wood lice, prairie dogs, by fires, unusually early or late frosts, or by failure on the part of the i)]ant to ri])en seed. This latter contingency frequently occurs in the case of the big blue stem and feather sedge, and j^robably with some other of the Andropo- gon species. The curly mesquite will stand almost any amount of drought, trampling, and hard usage, but is easily killed and rotted out during a wet, cold winter. The drought-resistant needle grass is fre- quently destroyed by wood lice over considerable areas. This usually happens in the spring on burned areas after light local showers. Finally, the entire seed crop may be destroyed by early autumn fires. Thus it is seen that through some one of many natural causes a species of grass may be all but exterminated and its place taken by others, often of less value. On overstocked lands there is uniformly an alternation of needle grass and mes(iuite at short intervals, unless the overstocking is carried too far, when these perennials give way to annuals and worthless weeds. The carrying capacity then depends almost absolutely on the i>roper distribution of rainfall through the growing season in order to briug this transient vegetation to its fullest maturity. THE COASTAL PRAIRIES. The low-lying i>rairies along the shores of the Gulf of Mexico con- stitute a region of very recent geological formation; in fact, so recent 29 that many of the fossils contained in the strata are identical with the species now living- in the waters of the Gulf The alluvial plain is flat, swami)y, and poorly drained, and is intersected by numerous sluggish streams with precipitous banks. The land is well grassed wherever it has not been overstocked, and the vegetation is very similar to that of the savannas and coastal plains in the Gulf States. Along the immediate coast there is usually a sloping beach backed by a line of not very high nor very broad sand dunes. There are no drift- ing sand dunes to compare with those along the Atlantic coast except at intervals opposite the "jiasses" between the coastal barrier islands, where the winds and tides have free sweep from the ocean. Wlierever the coast is protected from these by the islands, the only dune is about 100 yards back from high tide, perhaps not more marked than a narrow ridge, a few feet in height, whose surface is well covered with vegeta- tion. On the land side of the dune there is usually a lagoon, and back of this a marsh containing numerous more or less parallel lagoons and sluggish water courses. This marsh extends from 2 or 3 to sometimes 15 or 20 or more miles back along the entire coast line from the mouth of the Sabine River to Aransas Pass. The dominant grass on the beach between the ridge and the water is usually salt grass {Distichlis Hpicata). On the sand ridge there are Era- grostis secundijiora^ salt grass, and slender cord grass {Spartina patens). On the seaward edge of the marsh, which is frequently inundated, the l^rincipal grass is Monanthochloe littoralis, a rough, wiry species with extremely short, harsh, and shari^-i^ointed leaves. This could never be called a turf grass, and yet its interlaced stems form the closest kind of a mat, extending from 100 yards to a mile or more inland, depending on the elevation of the land above high tide. Next in the succession is the bunch salt grass {Spartina junciformis) (fig. 1), which grows in great tufts 3 to 6 feet across and from L to 1 feet in height. The leaves of this are evergreen, harsh, and rather stiff, spiny pointed, and so sharp that they will make a horse's legs sore when he is ridden through or over it. The leaves are resinous, and will burn at any time during the year, smouldering along even through a shower of considerable vio- lence. Between the tufts or tussocks the ground is either bare or covered with low rushes or other insignificant plants. The salt grass supplies fully 90 per cent of the vegetation of the marsh, and often occupies its surface to the almost total exclusion of other sorts. These salt-grass meadows are well stocked with cattle. Unlike the salt grasses of the marshes along the Atlantic coast, this can not be mown for hay on account of its bunchy nature, and hence grazing is the only practicable method of utilizing the vast amount of forage produced. The bunch salt-grass marshes will carry from 80 to 120 ]3ead of stock cattle to the square mile. It is said to be a fine grass on ^hich to f/roic cattle, but they can not be fattened on it; at least, that js the. opinion of a stockman iii Brazoria Gounty who has ranged cattle so l"'iu. 1.— I5uuili Hall gruBH (iyiiardnajunciformin) 31 ou the marshes for forty-five years. When the stock are nearly matured they must be takeu to the i)rairies farther iuhiud or shipped to the fattening jyens. The only treatment ever given the marsh pastures is to burn them over at intervals of three or four years. This clears out the dead leaves and stems that fill the centers of the tussocks and acts as a fertilizer by adding a top dressing of ashes. Marsh soils are as a rule deficient in potash, and hence the marsh grasses need all that which is contained in the ashes. Summer burning should never be practiced on the salt marshes, because to destroy the entire i)lant to the roots at the time it is in its prime is simply to needhissly sap its vitality; whereas if the grass is burned in late winter or early spring- while it is resting, before the new growth starts, the burning over will act as a stimulant to quicken the growth and in- crease the amount of vegetation . The extent of salt, marshes along the coast between the Sa- bine Itiver and their southern terminus amounts to perhaps 1,000 square miles, which at the estimated grazing capacity as given above can support yearly between 80,000 and 120,000head of cattle. The best ranches in this sec- tion of the coastal plain are those whicli extend far enough back from the tide water to include some of the sedge grass jjrai- ries and wooded bottoms. The cattle may then be transferred from one character of pasture to another with the changing seasons, thus providing both variety of diet for the growing cattle and also securing that alternate grazing and resting which is most desirable in the formation of the best pastures. The open prairies, where they still occur, are very fine grazing lands. They are covered with a great variety of species, it often being possi- ble to gather fifty or more different kinds on a single section in one day. The most conspicuous of these are the sedge grasses: Feather sedge [Androponoit saceharoide.s), Torrey's sedge (var. iorret/anus) (fig. 2), ami big blue stem {A. j/rocmvialin). The first of these is very abundant Fiii. -Torrey's sedge grass (Andropogon aaccha- roides turreyanus). 32 aud has caused the stockmen to refer to these meadows as the "sedge- grass prairies." However conspicuous these grasses may be, they are not the most abundant. There are a few spots where the sedge grasses occur so thickly that they make up fully 80 per cent of the vegetation. But in the majority of the coastal prairie pastures the sedge grasses do not amount to more than 10 per cent. On prairies at the mouth of the Brazos River buffalo grass [Bulbilis dactyloidcs) comprises about 60 per cent of the total, while rescue {Broinus unioloides), knot grass {Paspalum compressuni), Bermuda {Cynod. olii/ostachya), and buffalo grass {Bulbilis daetyloides). These species supply the larger part of the grazing, especially in the northern portion of the Plains. On the sandy lands in the southern half of the Plains, feather sedge {Andropogon saccharoides) coming up from the prairies of south- ern Texas displaces tlie little blue stem, and a number of other grasses identical with those of the Pecos Valley are abundant, including the 42 two species of black grama {Bouteloua eriopoda and Hilaria mutica), aud the southwestern species of Sporoholus, Muhlenheryia, Aristida, and Panicum. In the southern portion of the Phiins the number of species of granias {Bouteloua) increases aud they, together with iZiiarm mutica, form the bulk of the grass vegetation. The gramas of this region are Bouteloua polystachya, B. oliyostachya, B. eriopoda, B. vestit((, B. curti- pendula^ B. hirsuta, and B. ramosa. The number of species of Sporoho- lus also increases, and Aristida arizonica, A. micrantka, and A. bromoides take the place of the common dog-towu needle grass {A. fasciculata) of the i)rairies. Because of the absence of running streams and surface water for stock purposes, the Staked Plains have been less severely overgrazed than the lower plains and prairies surrounding them. Now, however, since it is found that water is fairly abundant aud within reach of windmill power, the land is being rapidly stocked. The grazing capacity is higher than m many other portions of the range country which have been stocked for a much longer period. The best means of improving the range on the Staked Plains are, first, to provide stock water at intervals not greater than 4 or 5 miles apart, so that cattle will not have to travel more than 2h miles in any direction; second, to provide winter shelter or protection from the storms which have uninterrupted sweep over this table-land during the winter months; and, third, to provide sufficient hay or coarse fodder to feed the cattle during the heavy storms. On almost every ranch there will be found old lake beds, sinks, or shallow valleys where the soil contains enough moisture within reach of the surface to be readily available to the roots of cultivated i)lants. On such lands sorghum, Kafir corn, milo maize, the millets, and iu especially favored localities alfalfa, and perhaps the soy bean, can be grown, and enough hay saved to provide against periods of shortage either during winter or in time of drought. The carrying capacity of the Plains ranges from 40 to G4 head per square mile. Assuming the preposterously low figure of 30 head per square mile as the average annual grazing capacity, more than 1,000,000 head of cattle can be pastured. The capacity for improvement here is as great as in any other part of the Southwest, so that with a Judicious use of the natural resources the number can easily be doubled or trebled within the next ten years. THE PECOS VALLEY. The Pecos Vallc}' in New .Alexico, extending almost due north and soutli, from about the thirty-fourth parallel to the southern border of the State, was formerly very well grassed. All of the living tribu- taries of the Pecos below Fort Sumner enter it from the west. For fully 200 miles below this ])oint there is no stream of any importance which drains into the Pecos Jtiver from the direction of the Staked Plains. The lauds iu the valley are exceptionally well located lor culti- 43 vation under irrigation, and several hundred thousand acres are under ditch, Avhile it is estimated that 1,000,000 acres are capable of being thus improved. The principal grasses in the Pecos Valley are salt grass [Dis- tichlis spicaia), in the alkali spots along the lowest portion of the valley, saccaton {Sporoholus icrighfii), wild rye {Elymns canadensis), western wheat grass [Afjropiiron spicatum), and alkali grass {Sporobo- lus airoides). Back from the immediate river valley on the richer bottom lamls blue grama {Bouteloua oligostachya) grows sometimes almost pure, or inter- miugled with woolly foot {B. eriopoda) (fig. 9), and black grama {Hilaria mutica). In the northern j)ortiou of the valley the grasses are practically iden- tical with those of the northern half of the Staked Plains. The gramas are the most abundant, supplying fully 80 per cent of the entire forage of the ranges, the balance being furnished by perhaps twenty- five or thirty species. The carrying capacity of the ranges in the Pecos Val- ley varies more widely than in any region in Texas, because of the unrestricted grazing of cattle and sheep on the public lands. In dry years there are often areas where 60 acres would hardly support 1 cow, while in good seasons the same lands if undergrazed in the droughty seasons will support from 40 to 60 head to the square mile. -w,r- q w n <• *,d .? y ii*ivy tiiii^j. ^ [^j g — \\ oolly-foot (Bouteloua eriopoda). RELATION OP LAND LAWS TO RANGE IMPROVEMENT. The range lands in Xew Mexico, with the exception of frontages along streams, sections, or quarter sections containing springs and land which may be artificially watered by shallow artesian wells, are still owned by the Federal Government, 69 per cent of the territory being Government land, and 58 per cent is classed as grazing lands, amounting to 45,000,000 acres. Texas having been independent pre- 44 vious to its annexation to the United States contains no public laud other than that belonging- to the State, and the use of pasture lands within its borders is regulated entirely by State land laws. With the exception of California it is the only one of the Western States where the ownership of the ranges does not lie entirely in the National Gov- ernment. The only way in which the noninineral lands can be filed upon is either under the right of preemption, under timber claim laws, desert land laws, or those relating to irrigated lands. There is no sys- tem for disposing of areas unsuited for agriculture other than under some one of these laws, and the result is that the grazing lands are held as commons open to any stockman who can ruu his cattle upon them. There is no law ivliich recognizes the existence of pasture lands or in any n- ay provides for their management and disposal. The problem of range improvement in Xew Mexico, and in every one of the Western States and Territories where there are still large bodies of Government lauds, is not wholly the introduction of new and better grasses nor the cultivation of better forage crops. The first and foremost necessity, if the extravagant waste of the public domain is to be prevented, is to devise some system by which grazing lands can be placed in a class separate from agricultural lands, and under which property rights in lands now free to everyone may be assumed by indi- vidual stockmen.* It has been the experience in all pastoral countries that proper care and conservation of the forage resources can only be secured and will only be practiced where the tenure of the land is sure. The necessary fixity of tenure might be legally provided for by long-term leases directly from the General Government at a nominal rental per acre. As it is at present, xhe value of the grazing on the public lands depends almost entirely upon such matters as seasonal rainfall and accessibility. The winter of 1896-97 was accompanied by exceptionally heavy rainfall over almost the entire southern and eastern portion of New Mexico. This combined with the extraordinarj^ shortage of cattle on the ranges permitted the rapid develo])ment of the range grasses, so that during 1897-98 the snpply of feed was unusually large; and, Avhereas the sonthern ])()rtion of the valley not having received any more than the normal i)recii)itation, would not carry in the spring of 1897 more than 10 to 20 head per square mile, the upper portion of the valley at the same period was covered with grasses and would have carried at least 50 head to the mile on almost any i)ortion of it. Aside from the effect of overgrazing on the lands themselves and on the natural grasses with which they are covered, it is well to note that millions of cattle .and sheep are grazed on free lands in every Western State and Territory. These lands contribute no taxes for the support of the State governments. The cattle when marketed may be sold at a much lower figure than those raised on taxed lands owned bj'^ the-stock " F. V. Covillc, in Forum, Septomber, 1898. 45 grower and still make a profit. It is not fair to the people who are compelled to bear the expenses of local government for large untaxed areas, nor on the other hand to the cattle men and woolgrowers of the East whose products come into competition with those grown almost without expense on free Government lands. The policy which governed the settlement of the prairie States might well be modified to meet the demands of the stock raisers, especially as a very large percentage of the Government land now remaining is not agricultural and can not be made so by irrigation. The best policy is that which will the best promote permanent settlement. It is necessary that timely action shall be taken to open up the public lands for settlement in tracts extensive enough to encourage men to build ranches and make permanent improve- ments upon them. The continued existence of great bodies of free lands covered with free grass is demoralizing to all those who take advantage of the opportunities presented thereby. As suggested above, probably the most feasible plan would be to provide for long-term leases of the public lauds for grazing purposes. BENEFITS OF IMPROVING THE RANGES. The number of cattle owned in the State of Texas on January 1, 1899, was estimated at 4,533,897 head, valued at $7G,6G5,937. At the same time there were 2,513,917 head of sheep, valued at $4,448,039, and 1,137,015 horses, valued at $20,088,788. The total value of sheep, horses, and cattle, exclusive of milch cows, at that date was $101,202,764. Nearly all of the sheep and a majority of the cattle and horses were grazed or fed within the territory included in this report. It can be safely taken as correct that 75 per cent of the 8,215,000 of live stock of these three classes is pastured on an area of less than 200,000 square miles, or, in round numbers, about six and one-fifth million head of stock are pastured on one hundred and thirty million acres of land. iSTow, if by any of the methods which have been suggested here, or by any treatment which may be devised, the carrying capacity of these arid land pastures could be improved and increased even to the extent of 25 per cent, it would mean an increase in taxable values of the State of at least $25,000,000. It is the opinion of a majority of stockmen who have raised cattle and sheep in Texas and Kew Mexico during the last twenty-five years that there has been a marked decrease in the amount and value of the natural forage, resulting in a proportional decrease in the number of cattle grazed. As has been stated above, an average of decrease taken from estimates made by 300 stock owners in Texas in 1897 was about 40 per cent. There is no doubt whatever in the minds of men who have studied the capabilities of the Texas soils that the lauds themselves are nearly as fertile as they ever were. In fact, it is a general law that the lauds in exclusively pastoral countries are continually improving in fertility as opposed to lands devoted to the cultivation of cereal and staple crops, because little of the essen- 46 tial mineral ingredients are removed, while the organic matter in the soils is steadily increased. Fortj^ per cent of increase over present capacities is not an improbable one, and there are many of the more sangnine stockmen Avho believe that the grazing capacity of large areas can be increased 100 per cent by undertaking proper methods of treat- ment. Such improvement will undoubtedly be slow, but the results will justify the eftort. INDEX. I'age.

C, April 8, 1899. Sir : I liave the honor to transmit herewith the manu- scrii)t and illustrations for "American Grasses — II," and recommend its publication as Bulletin No. 17 of this Division. "American Grasses — I" was published as Bulletin No. 7, and contained illustrations of 302 species. In this second part 325 additional species are described and illustrated, making a total ot G27 sp<^cies. Many of our grasses are here illustrated for the first time, and as a whole it is believed that the work will be helpful to students of grasses in determining the species of this most important family of plants. In the preparation of this part more attention has been given to synonymy aud to the citation of authorities, and the descriptions have been extended in order to facilitate identification. Of the species now illustrated, 19 may be regarded as characteristic of the Atlantic Coast region, 83 to the region of the Gulf of Mexico, 92 to the Southwest, in- cluding the States of Texas, New Mexico, Arizona, and southern California, 74 to the States of California, Ore- gon, and Washington, aud 61 to the Kocky Mountain region, of which 19 may be regarded as more properly the prairie species of that region. The distribution of some of the si^ecies is very limited, while that of others may extend tlirougUoiit all the States and even to other countries. The genus Blepharoneuron Nash is here recognized, while Stapfia Davy is referred to AnthochJoa Xees. A few species are here published for the first time, and a number of those recently described as new, particularly of the genus Panicum, are included more for the pur- pose of calling attention to them than as an expression of tlie acceptance of their validity. In the two parts eighty-seven species of Panicum are illustrated, many of them by drawings made from type specimens. For information concerning the forage or other economic values of the species described, reference is made to previously published bulletins of the Division, especially to Bulletin No. 14. The illustrations are of the same character as in American Grasses— I (Bul- letin No. 7), and have been executed by the same artists. Kespectfully, F. Lamson-Scribner, Ayrostoloijisf. Hou.

The metric system adopted in this bulletin, as in No. 7, is now quite generally employed in botanical and other scientific publications. For those unfamiliar with this system the following expression of equivalents may be useful : 1 millimetre (1 mm.) = «iie twenty-fifth of an inch — exactly 0.0394 inch. 1 ceutinietre (1 cm.)=nearly one-half of au inch ; 10 cm. = about 4 inches. 1 decimetre (1 dm. ) = about 4 inches, or 3 dm. = 1 foot. 1 mitre (1 m.) =ab.)ut 3 feet 3f inches— exactly 39.37079 inches. 6 Fig. 303.

SIT ANION VILLOSUM .1. G. Smith, sp. nov. PI. I. Culms stout, erect, or slightly geniculate, 2 to 3 dm. high, densely leafy at the base, forming close, matted tufts. Sheaths rather densely hirsute, the lower strict, the uppermost somewhat inflated, scabrous. Ligule almost obsolete. Blades short, rigid, ascending or divaricate, flnely strigose-pubescent aud more or less densely hirsute, scabrous along the cartilaginous margin.s, linear-lanceolate, acuminate, puugently-pointed, 4 to 8 cm. long, about 3 mm. wide, flat, or at length involute. Spike G to 8 cm. long, subflexuous, its base inclosed in the greatly elongated uppermost leaf-sheath. Empty glume 3- to 7- or 8-parted from near the base, each lobe a very slender, scabrous, divaricate awn from 2.5 to 8 cm. long. Lowest floret usually sterile, its glume many-parted, like the empty glumes. Perfect florets 1 or 2. Flowering glume about 8 mm. long, obli(iuely lanceolate, smooth and shining at the base, scabrous for the upper two-thirds, 3-awued, the middle awn rather stout, divergent, 8 to 10 cm. long, the lateral ones very slender, 5 to 10 ram. long Palca as long as the flowering glume, obtuse, acute, or with two short, slender awns at the apex.

E, Elmer, No. 266, on rocky hilltops, Almota, Whitman County, Wash., June 13, 1896; also collected by C. V. Piper, Xo. 2.598, on dry, gravelly prairies, Spokane, June 2.5, 1897; aud Hobert M. Horner, No. 574, Waitsburg, Wash., June 3, 1897. This species may be separated from Sitanion pohjantherlx, to which it is closely related, by the short, rigid, hirsute basal culm leaves. 3. SITANION MULTISETUM J. G. Smith, sp. nov. Culms 3 to 5 dm. high, terete, striate, glabrous or .minutely strigose-pubescent, erect or slightly geniculate, much branched from the very base. Sheaths rather loose, open at the throat, scarious along the margins above, strigose-pubescent and hirsute on the back, mostly longer than the internodes. Ligule very short, membranaceous. Blades 5 to 10 cm. long, rigid, erect or ascending, linear, acute and puugently pointed, flat, becoming involute, sparsely hirsute on the back, scabrous on the margins, hirsute and scabrous along the prominent nerves above. Spike erect, 5 to 8 cm. long. Spikelets two at each node but usually only one bearing perfect florets. Empty glumes many-parted nearly to the base, the slender, ascending, scabrous awns varying from 1 to 5 or rarely 8 cm. long. Lowest flowering glume of the sterile spikelet subulate, resembling the segments of the empty glumes, but somewhat lanceolate at the base. Flowering glume of the fertile spikelet about 8 or 9 mm. long, linear-lanceolate, rounded on the back, smooth aud shining below, keeled and scabrous above, 3-awned, the middle awn stout, rigid, scabrous, 5 to 6 cm. long, the lateral ones slender, 3 to 8 mm, long. Palea as long as the flowering glume, acute or bicuspidate. Internodes of the rachis compressed, spatulate above, smooth and shining, scabrous along the margins, 4 to 5 mm. long. Type specimen collected by Coville and Funston. Xo. 1121, Tehachapi Valley, Kern County, Cal., June 25, 1891. Other specimens which may be referred to this are Samuels, No. 225, Sonoma County, Cal. ; a specimen collected by Bolander at San Francisco without date or number ; Dr. Palmer, No. 2422, Petaluma, 1892 ; Hansen, No. 617, Clinton, Amador County, June 30, 1893 ; a specimen marked "J. A. Allen, California ; " and L. Schoenefeldt, No. 3439, Nachoguero Valley, Lower California, June 14, 1894. It diff"ers from SUaiiion pohjanlherix and .?. hreviaristatnm iu the very much longer and more rigid, erect or ascending awns of the empty glumes, and the leaves hirsute dorsally toward the base and along the nerves above. 12 4.

Type lollected by Sereno Watson, No. 1338, Carrington Island, Salt Lake, Utah, .June, 1869. This species is quite distinct from any other in the National Herbarium. It has the broad empty glumes of Klj/iinis, but two-})arted, as in Kiisilatiioii, with divaricate aw lis. Tlie emi>ty glumes are inserted as in Siianio)i. while the form of the spikelets and the habitat of the inflorescence resembles some species of J en at the throat, closely enveloping the internodes. Ligule almost obsolete.

Clements, No. 60, Wal- senburg, July 10, 1896. There are in the herbarium of the Philadelphia Academy of Science two of Nuttall's specimens of SUanion. One of these, labeled " Chretomeris trichoides, R. Mts. Platte," is exactly identical with No. 3784, A. Nelson, and No. 283, C. L. Shear, both collected in the Red Desert of Wyoming. The other, labeled "Elijmus difformi.% R. Mts. Platte," is nearly identical with No. 2028, Rydberg, from Wam- sutter, Wyo. If these specimens are those from which Nuttall's description of JEgilops hyatrix was drawn, and they agree lietter with liis description than any specimen from the "arid plains of the Missouri "so far examined, then there was undoubtedly a mistake made iu referring the habitat of this to that locality. I am assured by Dr. E. L. Greene that it is highly improbable that Rafiuesque drew his description of S. ehjmoides from Nuttall's plant, and it is certain that Rafln- esque's description (Jouru. Phys. 89 : 1819) differs in important particulars from that of J'lgUops hjistrix, Nuttall. I am, however, unable definitely to identify any SUanion with which I am familiar as the true S. elymoides, Raf. The locality, "Missouri," of 1819, was then applied to what now constitutes several largo 16 Siat< s in wliicli a dozeu or iiioro separatt* spt-cies occur. I?atiiies(|ne apparently li fi no type, and the original description is too fragmentary to enable one to more than jiues8 at the identity of the plant which he described. 13. SITANION CiEsPITOSUM J.

Closely related to S. lanceolatum, from which it differs in the glaucous sheaths and culms, flat, lanceolate leaves which are very smooth on the back, and the pur- plish, long-exserted spikes with glaucous florets. 20 21. SITANION LANCEOLATUM J. G. Smith, sp. iiov. Culms 2..") to 5 dm. high, erect or ascendiug, ami somewhat geuicalate at the lower nodes. Culms terete, smooth aud ascending, striate above. Nodes glabrous. Sheaths glabrous, striate, closely euvelopiug tlie culms, longer than the inter- nodes. Ligule almost obsolete. 15lades 8 to 15 cm. long, 2 to 3 mm. wide, rather rigid, linear, erect, or the basal ones divergent, flat or convolute, glabrous on the back, scabrous on the margins and nerves above. Spike erect, G to 10 cm. long, barely exserted, or its base imludod in the uppermost leaf-sheath. Spike- lets cylindrical, subcompressed, the florets closely overlapping one another. Empty glumes 5 to 6 mm. long, keeled, lanceolate, 2-nerved, oblique, scarious on the margins, entire or iine<|ually 2-awned, the longer awn scabrous, diver- gent, 10 to 15 mm. long. Flowering glume 8 to 9 mm. long, glaucous, rounded on the back, lanceolate, entire, or minutely 3-toothed at the apex, with a stout, scabrous, divergent awn 2 to 4 cm. long. Palea as long as its glume, obtuse or emarginate, scabrous on the margins above. Joints of the rachis, 5 to 7 mm. long, linear, spatulate, compressed, scabrous on the margins. Type collected by P. A. Eydberg, No. 3381, Barker, Mont., August 17, 1896. The habit of this grass resembles that o{ Af/rojnjron caninoide'i Beal; the spikelets and empty glumes are arranged as in Elymus, 1)ut the nervation of the empty glumes, trifid flowering glume, and the rachis dehiscent at the nodes, are suf- ficient characters to throw this species into Siianion. 22. SITANION HANSENI (Scribn.) J. G. Smith, nom. nov. Elymus hanseni Scribn. U. S. Dept. Agr., Div. Agros., Bull. 11 : p. 56. 1898. "A rather stout, glabrous perennial, 9 to 12 dm. high, with narrow, spreading leaves and slender fragile spikes 5 to 8 cm. long. Sheaths smooth, striate. Ligule very short, hardly 1 mm. in length, entire. Leaf-blades 10 to 30 cm. long, 2 to 5 mm. wide. Internodes of the racliis about 1 cm. long. Spikelets 3- to 5-flow- ered, about 1.5 cm. long, exclusive of the awns. Empty glumes lanceolate, strongly nerved, tipped with 2, sometimes 3, unequal awns, the longer about 3.5 cm. First flowering glume 10 to 12 mm. long, entire or 2-toothed at the apex, terminating in a straight or very slender awn about 5 cm. long. Palea about the length of the glume, minutely scabrous on the sharp keels except at the base, slightly pubescent at the truncate or 2-tootlied apex." Amador County, Cal. Related to S. anomalitm, but taller aud more slender, with mostly single rather remote spikelets, which are longer. 23. SITANION ANOMALUM J. G. Smith, sp. nov. (PI. IV). Culms erect or ascending, 5 to 6 dm. higli, terete, smooth. Nodes glabrous. Sheaths smooth or the lower sparsely hirsute, ciliate along the maxgins, shorter than the internodes. Ligule nuinbranous, 1 mm. long. Blades 4 to 12 cm. Jong, 3 to 4 mm. wide, involute, rigid, linear, long-attenuate, scabrous throughout. Inllo- rescence simple or thyrsiform, 1 to 1.5 dm. long, few-llowered, interrupted below, subllexuous. Siiikelets compressed, 4-flowered, the florcta distant. Empty ghimes mostly lanceolate, entire, but those of the lowermost s^dkelets bifid above the middle, with short, scabrous, divergent awns 1 to 4 cm. long.
