Thirty-eight years later, in 1866, Edward Enfield published in New York a book on "Indian Corn; Its Value, Cul- ture and Uses." These are the only volumes in the English language, within the knowledge of the writer, that have been written as hand- books on Indian corn for farmers. Since these books were issued much valuable information has accumulated concerning the corn plant, and it is due to this fact that this volume was written. In America this cereal is grown more extensively than is any other, and its great food value for man and beast is fully recognized. For a large amount of the present knowledge we have of Indian corn Ave are indebted to the researches conducted at the agricultural ex- Digitized by the Internet Archive in 2010 with funding from University of British Columbia Library http://www.archive.org/details/indiancorncultuOOplum CHAPTER I, HISTORICAL. Indian corn, the Zea niai/s of botanists, is un- questionably native to America. Before the discovery of this country by Columbus this cereal was unknown in Europe, Asia or Africa. Maize was undoul)tedly grown by the inhabit- .ants of North, Central and South America in prehistoric times. Mounds that were erected prior to the time of the American Indian, of which he has no tradition, that have been ex- plored in recent years, have contained corncobs and charred kernels. In mounds excavated at Madisonville, 0., in 1879, remains of maize were found in quantities. In the caves occupied by the early Cliff Dwellers in the southwestern United States, ears of corn have been frequently discovered. In South America Darwin found on the coast of Peru, "heads of maize, together with eighteen species of recent sea shells, em- bedded in a beach which had been upraised at least eighty-five feet above the level of the sea."* * Animals and Plants under Domestication, New York, 1890, I, p. 338. (7) b INDIAN CORN CULTURE. Eai-s of Indian corn are occasionally found in vessels placed in ancient Indian tombs or mounds in Chili, Peru and Central America. The Smithsonian Institute at Washington has numerous interesting specimens of corn, ex- humed from mounds and tombs, that must be very ancient. One specimen was discovered deposited in an earthen vessel eleven feet under ground in a grave with a mummy, near Ari- cpiipe, Peru.* Marcay refers to corn found in Aymara Indian tombs in South America, that, from the material accompanying it, must belong to a period long before the Spanish conquest.f Among the ruins of Peru are stone carvings of ears of corn, executed centuries ago, before the discovery by Europeans. Original Home. — The original home of In- dian corn is thought by some to be Central America or Mexico, south of the twenty-second degree of north latitude.}: In 1888 Prof. Duges collected at Moro Leon, north of Lake Cuitzco, Mexico, several corn i^lants wdiich have been termed wild maize, and considered by some to be the original parent of Indian corn. Plants from this source were grown at the Cambridge, * Report United States Department of Agriculture. 1870 p. 420. t Travels in South America, I, p. 69. J Maize: A botanical and economical study, by John W. Harshberger, 1893, p. 202. HISTORICAL. ') Mass., botanical gardens, at Philadelphia and at Ithaca, N. Y. The Indians of Mexico and the southwestern United States have for centuries grown corn very similar in general conformation to that found in the mounds of ancient times, which is quite unlike that grown in the northern corn belt. This corn is soft or starchy, of color rang- ing from white to pink, blue and other shades, has a large cob, and round, smooth topped kernels of fair size. Says Sturtevant:* •'Centcotl, in Mexico, was goddess of maize, and hence of agriculture, and was known, according to Clavigero, by tlie title, among others, of Tonacajohua, 'she who sustains us.' Sahagrun writes of the seventy-eight chapels of the great Temple of Mexico, that the forty-fifth edifice was called Cinteupan, and therein was a statue of the god of maize." Indians as corn-growers. — The early Amer- ican explorers discovered the Indians cultivat- ing fields of maize, Delafield tells usf that "when Cartier visited Hochelaga, now called Montreal, in 1535, that town was situated in the midst of extensive cornfields," Champlain in 1608 found cornfields eastward from the Kennebec river. In 1621, Squanto, an Indian, showed the Puritans how to plant and care for maize, and some twenty acres were planted and successfully grown.:}: At the time of the Pequot * American Naturalist, March, 1885, p, 226. t Transactions New York State agricultural society, 1850, p, 386. t Harshberger; Maize: A botanical study, etc., p. 131. 10 INDIAN CORN CULTURE. war in 1637 the English destroyed over two hundred acres of corn planted by the Indians. The Puritans in King Philip's war, in 1675, took ''what he had worth, spoiled the rest, and also took possession of one thousand acres of corn, which was harvested by the English."* Wher- ever the early explorers or voyagers went they found either fields of Indian corn or the Indians using the grain for food. Capt. John Smith, in his ''Indians of Virginia," tells of the methods of planting at that time (1608). Cabeca de Vaca found an abundance of maize near Tampa Bay, Florida, in 15'28.f In 1679 La Salle, when on a trip through the Great Lakes and across Illinois, found large quantities of stored corn in a vil- lage of Illinois Indians and took about forty bushels of it.:]: Columbus in 1498 writes to Ferdinand and Isabella of the maize j)lant and of fields eighteen miles long. The early ex- plorers also noted maize as an important article of food for man in Yucatan, Nicaragua, and Mexico. Harshberger's conclusions. — In his impor- tant historical study of maize, Harshberger says:§ "The evidence of archaeology, history, ethnology, and philology, which points to central and southern Mexico as * Harshberger; Maize: A botanical study, etc., p. 131. t Torrey Botanical Cluh Bulletin, VI, p. 86. it Harshberger; Maize: A botanical study, etc., p. 135. I Ibid., p. 151. HISTORICAL. 1 I the original home of maize, is supported by botany and meteorology. All of the plants closely related to maize are Mexican. It is an accepted evolutionary pi'inciple that sev- eral species of the same genus, or genera of the same tribe, though dispersed to the most distant quarters of the globe, must originally have proceeded from the same source, as they are descended from the same progenitors. It is also obvious that the individuals of the same species, though now in dis- tant regions, must have proceeded from one spot, where their parents were first produced; for it is incredible that individ- uals, identically the same, should have been produced from parents specifically distinct. Applying these principles to maize, we reach the conclusion that maize was originally Mexican. * * * The evidence to the present date (1893) places the original home of our American cereal, maize, in central Mexico." 12 INDIAN CORN CULTURE. CHAPTER II. BOTANICAL CHARACTERISTICS. Indian corn is known by botanists as Zea mays. It belongs to the grass family and is an annual plant. It is classed as an endogenous plant for the reason that it increases in height and diameter of stem by internal growth. The root is of two classes, primary and sec- ondary. The former is fine and fibrous, and in the field the plant produces a large mass of these roots. No long tap root is developed; consequently, as with the grasses generally, the roots branch out in all directions rather near the surface. For this reason shallow cultiva- tion of the growing crop is advocated, as break- ing the roots is deemed an injury to the grow- ing plant. In interesting experiments conducted by Prof. F. H. King at the AVisconsin experiment station* upon the development of corn roots in natural soils under the conditions of field cul- tivation, he washed out plants at different stages * Ninth annual report Wisconsin experiment station, 1892, p. 112. BOTANICAL CHARACTERISTICS. 1-) of growth. Forty-two days after planting, when the plants were 18 inches high, the roots of two hills met and passed each other in the center between rows 42 inches apart, and had penetrated to a depth of IS inches. The sur- face roots sloped gently dow^nward toward the center, where those nearest to the surface were some eight inches deep. At the last cultiva- tion, when the plants were nearly three feet high, the roots occupied the entire soil to a depth of two feet, with the surface roots six inches helow the center between the rows. At tassel time the roots fully occupied the upper three feet of soil in the entire field, and in the center between the rows the surface roots were still higher, a few being scarcely five inches deep. At maturity the roots were found pene- trating to a depth exceeding four feet and within four inches of the surface in the center between rows. In connection with this study Prof. King estimates that the plants on a well- tilled acre are recpiired to pump from below during growth from 300 to 400 tons of water. The wonderful feeding power of the corn roots is shown in this striking development and ac- tivity. After the corn plant becomes well established and has nearly reached its full height the sec- ondary roots come from the stem near the ground. They hrst appear as nodules from 14 INDIAN CORN CULTURE. which develop the root tips, which proceed to make a downward growth into the soil. After penetrating slightly below the surface a mass of fibrous roots is j^roduced from this buried portion. These roots assist in maintaining the erect position of the j)lant, as well as in secur- ing nourishment and moisture. Generally the depth of the planting does not influence the depth of the rooth growth. The stem (or culm) of Indian corn, varies in height from 18 inches to 18 feet, according to the variety and conditions of growth. Sturte- vant even notes one variety in South America attaining a height of 24 feet. The stem consists of a number of smooth sections (internodes), joined together l^y short joints (nodes). The mature stem has a pithy interior with a thin covering of harder material. In a study made by the writer on the rate of growth of the corn plant, at the New York experiment station it was noted that the in- crease ranged from three to 18^ inches per week in gain. The most rapid development occurred when the plants were about five weeks old. Under specially favorable conditions a growth of five inches has been recorded in one day. The leaves grow from the joints, there being a leaf at each one. For a greater part pf the stem, the lower part of the leaf (sheath) is wrapped about the stem from one joint almost BOTANICAL CHARACTERISTICS. 15 to the next. In a study of the corn plant at the Iowa experiment station,* the number of leaves on a stalk varied with field corn from 12 to IS, with a width of blade from 3| to 5^ in- ches. Microscopical examination of a numl)er of varieties showed considerable difference in the thickness of the leaf structure and in the amount of green coloring matter present. At the Missouri station. Prof. Schweitzer measured the leaf surface of a vigorous plant of average development.! 'The total surface of the twelve living leaves on one side was 1,633.73 square inches, which doubled for both sides, and add- ing the area of the outside of the sheaths, makes the total external leaf surface of this plant 3,480 square inches, or 24 square feet." Schweitzer considers the leaves the chief source of production of organic matter, and while 16 or IS may he produced in our climate, the lower ones die off before maturity, and activity is confined to perhaps twelve. The flower is of two kinds, male and female. The former is known as the tassel, and is situ- ated at the tip of the stem in the form of a l)ranching head (panicle), while the latter is lo- cated in between the sheaths of leaf and stem. * Iowa agricultural college experiment station.

The tassel contains many small flowers (see Fig. 1), and each of these produces a large amount of pollen or dust for fertilizing the female flowers. This pollen is from I \ W 1 i \'W\WJ/i the anthers of the flowers, and accord- '^^111 ii ing to Harshberger* as many as 2,500 are formed in a Fig. 1.— The stem at left Is a branch of the • i 4-1 n • onrl male panicle, showing spikelets.

The female (pistillate) flowers being located below the male (staminate), the pollen of the male is Iflown about in the air and falls onto the silks which protrude from the enclosing husks, and fertilizes them. Each silk extends back into the husk and to the seat of what will become a kernel of corn if fully fertilized. The content of this husk is an embryo ear of corn. The portion of the silk exposed is somewhat hairy without, and is a hollow tube within. * Maize: A botanical study, etc., p. 85.

In Fig. 3 the shaded parts of kernel above the base represent hard or corneous mat- ter ; the white parts starchy matter. Pop corn. — The substance of the center ker- nel is hard and flinty (corneous) all through, excepting at the germ end, no white, soft starchy substance being present. See a in Fig. 3. Flint corn. — The corneous matter surrounds the sides and top of the kernel, so that it is en- closed in a hard, flinty coat, with soft starchy substance in the central part. The kernel is usually about as broad as long, and rounding and smooth over the top. Flint corn is some- what smaller than dent, and is best suited to New England and the northern line of corn growing. See h in Fig. 3. Dent corn. — The sides of the kernels consist of corneous matter with the central part filled with soft material, even to the dented or con- tracted rough top. This contraction is due to shrinking of the softer part of the kernel in ripening. The kernel in many varieties is slender or wedge form. Nearly all the corn grown in the great corn belt of the Central West belongs to this race. See c in Fig. 3. Sweet corn. — The kernels consist of translu- cent, horny material, which contain consider- able sugar (glucose) instead of starch. The BOTANICAL CHARACTERISTICS. 19 kernels in most varieties are quite wrinkled or twisted and are distinctly wedge shape. See d in Fig. 3. Soft corn. — Excepting the germ the entire kernel is starchy and soft in character and has somewhat the form of the flints. This race is more commonly grown in the sub-tropical corn regions, as the far Southwest and in' Mexico. This is the early form of corn as grown by the Indians. See e in Fig. 8. Pod corn. — Additional to the above another form is found, which is rather uncommon. Pod or husk corn is a variety in wdiich each kernel is enclosed in a small husk, wdiile the aggrega- tion of kernels, which may form a long or short ear, is enclosed in large external husks on a simple cob, as with common ears. Flint and dent corn may exist in this variety. Pod-corn seed when planted will usually give a crop of both podded and unpodded ears. Classified by seed. — Each known variety of Indian corn may be easily classified with one of the so-called races, according to its seed. However, if two or more races are grown near l)y there will no doubt be ears composed of a. mixture of each class, especially if the flowers develop at the same time. 20 INDIAX COKX CULTURE.

As a rule luit few have remained in general public favor for a long term of years, as it is ditticnlt to iinJ a variety that will adapt itself to a wide geographical range and climatic and soil variations. Selecting a variety. — In selecting a variety two things necessarily should receive considera- tion: first, the capacity to mature a crop in a given locality, and secondly, productiveness in grain, or u-rain and forage. In this work it seems best to discuss this subject iu two ways: first, to describe a number of standard varieties, and secondly, to give a list of varieties adapted to different States, covering a wi^le territory. The descriptions of varieties are gleaned from various sources, but unless otherwise indicated, are mainly on the basis of the published inves- tigations of Dr. E. L. Stui*tevant (our best au- thoritvon varieties) in the Xew York State ex- VARIETIES AND THEIR ADAPTATION. 21 periment station repoiis, and the Inilletins of the Illinois agricultural experiment station.

Tested varieties. — The following varieties have been well-tested in this countiy, some of them for many years, and it is believed that from this list one can nnike a most satisfactory selection for almost any part of the I'nited States or Canada.

This scale is not entirely satisfactoi-y. It would be difficult to mark point B, as it is assumed that the judge is passing on a variety, and the question of purity he could not answer. Point D is also a weak one. as the earliness could not be determined by the degree of ripe- ness. In judging K the corn should be per- fectly dry, else the comparisons would not be fair. In any event, such a score card could only be used in scoring exhibits on a mercan- tile basis, and not a variety one. Not enough is known about variety characteristics to per- mit this fairly. At the present time the method of judging in vogue is considered unsatisfactory, and an effort is being made to establish the use of the score card. It is to be hoped that a scale of points will be adopted such as will give satis- tion and be generally used. 58 INDIAN CORN CULTURE. CHAPTER V. MANURES AND FERTILIZERS. It is a generally recognized fact that to re- move a crop from the soil is to take from it a certain amount of fertility or plant food. If this practice is continued without returning this food in some form to the soil it becomes much impoverished and less and less produc- tive. Fertilizers necessary. — A crop of 50 bushels of Indian corn and 8.0U0 lbs. of cornstalks per acre will remove from the soil 79.8 lbs. nitro- gen, 55.2 lbs. phosphoric acid and 87.6 lbs. potash.* To remove such a crop is a heavy drain on the soil fertility, and to purchase in the markets the amounts of nitrogen, phos- phoric acid and potash removed by it would cost about $20. In the great corn-growing region of the country, however, a large amount of land is annually planted which contains so much available plant food that the farmer does not feel justified in placing artificial ferti- * Science in Farming, 1882, p. 153. MANURES AND FERTILIZERS. 59 lizers upon it, although staV)le manure is some- times used. Deep, black prairie soils of the new West do not as j'et need additional plant food," although the time is soon coming when they will. Again there are alluvial river bottoms subject to annual overflows which so enrich them that artificial fertilization is un- necessary, for such bottoms grow large, flue crops of corn year after year. In the Eastern, Middle, and Southern States, however, soils have become impoverished by constant crop- ping, and each year enough plant food should 1)6 returned to them to keep them highly pro- ductive. It is safe to say that the only way to deter- mine certainly what manure or fertilizer is best suited to one's land is to experiment on it on a simple, practical basis. Stable manure is always a standard material for enriching the land, and it is suited to the needs of all classes of crops and all kinds of soils. Its effect is more lasting than the read- ily soluble commercial fertilizer. Since 18S3 an experiment has been in progress at the ex- periment station at Purdue University to de- termine how long stal)le manure will continue to affect the yield of succeeding crops. The plat set apart for this experiment has been pro- ducing corn continuously since 1879. To cer- tain plats in the series fresh horse manure was 60 INDIAN CORN CULTURE. applied in 1883 and again in 1884, amounting for the two years to about 50 tons per acre. No manure has been used in this experiment before or since the two years named. The av- erage results of the 11 years of cropping have shown a yearly gain of 10.42 l)u. of corn per acre for the manured plats over those unma- nured. In other experiments at Purdue, in charge of Prof. Latta who conducted the preceding one, fresh horse manure has always given greater returns from its application than artificial fer- tilizers, singly or in combination. Both six and nine tons of the manure per acre gave larger yields than wliere fertilizers were used under any circumstances. At the Connecticut station for four years a comparison has been made of the influence of cow manure, hog manure, and fertilizer-chem- icals upon a corn crop grown continuously on the same land.* The yields from plats given cow and hog manure in excess of the .exhaus- tion by cropping have been essentially the same during the four years, averaging, however, slightly in favor of the hog manure. The fer- tilizer plat, which received more nitrogen, phosphoric acid and potash than the crop re- moved, gave about four-fifths as much dry * Connecticut State agricultural experiment station. Re- port for 1893, p. 286. MANURES AND FERTILIZERS. 61 matter as did tlie manured plat, while the uii- manured plat gave about three-fifths that of the manured. A liberal manuring increased the albuminoids in the crop; in the kernels there was a marked increase in the protein and nitrogen-free extract. At the Missouri station barn-yard manure (solid and liquid together) increased the yield.* At the Texas station, on poor, shallow, upland "post oak" subsoil of stiff clay, cow manure gave most profitalile returns, though bone meal produced the largest increase in yield. f Artificial fertilizers have been largely used with profit in this country, notably South and East. It would be useless, however, to recom- mend to the farmer the use of anything but a complete fertilizer for corn, not knowing the soil conditions or the adaptability of a given farm to this cereal. If the soil is deficient in nitrogen, potash or phosphoric acid, the best way to do will be to try some special fertilizers containing these ingredients, and so determine just what the land needs most. It will be safe, however, unless in exceptional circumstances, to use plenty of stable manure for the cornfield and then supplement this with a dressing of fertilizer. * Missouri agricultural experiment station, Bulletin Xo. 14. t Texas ag-ricultural experiment station, repoi-t for 1SS9, p. 11. 62 INDIAN CORN CULTURE. Experiments with fertilizers.— It is inter- esting, however, to note some of the results from using fertilizers experimentally on corn. Much of this work has been done with great care, and may be suggestive, if not having a direct application. In 1881 Prof. W. 0. Atwater, in an address before the Connecticut State board of agricul- ture, reported on the effects of fertilizing materials upon corn grown in 73 experiments on sandy or sandy loam soil, extending over the years 1878, 1879 and 1880. In these experi- ments, '"phosphoric acid took the leading place often, potash occasionally, and nitrogen very rarely." Prof. Atwater considers the experi- ments numerous and decisive enough to war- rant the inference that, as corn is commonly grown, nitrogenous fertilizers in any quantity would rarely be profitable. For several years past fertilizer experiments on corn have been conducted by the Storrs' (Connecticut) experiment station, under the direction of Prof. C. S. Phelps. "The crops grown on light soils were in nearly all cases greatly increased by the use of potash or nitro- gen, or both, while in only one case was there any considerable increase from the use of phos- phoric acid." On the heavy soils phosphoric acid gave l)y far the best results. "The experi- ments thus far made indicate that for corn, MANURES AND FERTILIZERS. 63 ou the lij^liter soils of the State, fertilizers con- tjiiiiing a lar<^e proportion of potash are needed to give the best results/' while fertilizers with rehitively large proportions of phosphoric acid produce the best results on heavy, clayey soils.* At the Massachusetts State experiment sta- tion for some years a series of 10 plats of one- tenth acre each in size have been grown to corn and treated with one or two special arti- cles of plant food, or else left un manured. In 1888 those plats receiving a dressing in which potash was the dominant ingredient gave ma- terially increased yields of grain over the nitro- gen plats, though a combination of 97 lbs. of sulphate of potash and magnesia and 100 lbs. of dissolved l)oneblack gave the best yield. In experiments conducted over the State of Massachusetts in 10 different counties^ by Prof. W. P. Brooks of the agricultural college, while it was shown that soils differ widely in their requirements, it was also demonstrated that potash more often proves beneficial or much more largely beneficial than either nitrogen or phosphoric acid.f Potash as a rule most largely increases the yield of both grain and stover, but its effect upon stover production is greater than upon grain production. *Storrs' agricultural experiment station. Report of 1892, p. 67. t Experiment Station Record, III, p. Ido. 64 INDIAN CORN CULTURE. At the Georgia station nitrogen experiments were conducted upon 25 plats of 3-40th acre each. In general the results indicated that "nitrogenous manure increased the yield of corn covered by the experiments; that nitrogen alone, regardless of the source, was more effec- tive in increasing the yield of corn than either phosphoric acid or potash, or both combined; but that when a large amount of fertilizer was to be applied to corn it was best to add all three of the elements."* In the general ferti- lizer experiments of this station in 1893 nitro- gen was the most effective fertilizer used, and it was concluded that at present prices of com- mercial fertilizers they could not be used with profit.l At the Ohio station in 1890 and 1891 some increase has followed the use of nitrogen in every case, but in 1888 there is no evidence that nitrogen, whether used alone or in com- bination with phosphoric acid, has produced any increase in crop beyond the limits of prob- able variation in the soil itself. "Experiments were conducted on five private farms in five counties, in which it was shown that (1) nitrate of soda in combination with dissolved bone- black or muriate of potash, one or both, has * Georgia agricultural experiment station, Bulletin 15, December. 1891. t Georgia station. Bulletin 23. December, 189.3. MANURES AND FERTILIZERS. 65 produced an increase of crop in 46 out of 48 trials; and (2) in no case has the iiK^-ease in crop been sufficient to pay cost of fertilizer."* This work is supplemented l)y further work along the same line.f Twenty-one separate experiments were made on soils varying widely in character and located in different parts of the State, and extending over at least six years. As a result of this work Director Thorne con- cludes: "At present prices of cereal cvups and of fertilizing ma- terials, respectively, the prolitable production of corn, wheat and oats upon chemical or commercial fertilizers, or upon barn-yard manure, if its cost be proportionate to that of the chemical constituents of fertility found in commercial fer- tilizers, is a hopeless undertaking:, unless these crops be grown in a systematic rotation with clover or a similar nitrogen-storing crop; and the poorer the soil in natural fer- tility the smaller the probability of profitable crop produc- tion by means of artificial fertilizers." At the Kentucky station, on land rich in phosphoric acid, a mixture of muriate of potash and nitrate of soda in the proportion of one part of the former to two of the la.tter gave the best yields of grain, viz.: an increase of 39 bushels per acre over where no fertilizer was applied. Combinations of nitrogen and phos- phoric acid, or single applications of either, gave practical] 3' a less yield than wdiere no *Ohio agricultural experiment station, Bulletin 3, Vol. V, March, 1892. ilUd., Bulletin 5.% March 1804. 5 66 INDIAN CORN CULTURE. fertilizer was applied, while combinations of potash and nitrogen, or potash alone, gave good yields.* At the Virginia station phosphoric acid gen- erally increased the yield. A full application of this cost but one-half as much as the potash and one-sixth as much as the nitrogen.f Fur- ther, where phosphoric acid was applied there was a larger proportion of the corn to fodder than in the other yields. In no instance did the nitrogen application give a gain equal to its cost. The Rhode Island station, on the basis of several experiments, advises the use of about 45 lbs. nitrogen, 75 lbs. potash and 54 lbs. phos- phoric acid per acre.}: Summary of experiments. — A careful ex- amination of the experiments in supplying fer- tility to the corn crop conducted by the differ- ent agricultural experiment stations shows, as might have been expected, much difference in the results secured. Wherever used stable or barn-yard manure was productive of good results. Combinations of nitrogen, potash and phosphoric acid gave satisfactory yields in * Kentucky agricultui'al experiment station.

MANURES AND FERTILIZERS. 67 many cases, but generally the cost of these was too much to make their use profitable. The value of phosphoric acid was especially shown in tests in Alabama, Louisiana, Pennsylvania and Vermont; that of nitrogen in Georgia, Massachusetts (local). New York and North Louisiana; that of potash in Kentucky, New Hampshire, New Jersey and Massachusetts (general). Cotton seed crushed, or cotton-seed meal is generally considered to be a most desirable nitrogen fertilizer. This used singly or in con- nection with artificial fertilizer is recommended for the corn crop. The meal may be sowed broadcast before planting and harrowed in, while the crushed seeds may be plowed under, as with stable manure. However, it would be better husbandry to feed the cotton seed or meal to live stock and use the manure, which will contain about all the fertilit}' of the orig- inal grain. Sea weeds, fish scrap or dead fish, night soil and other su))stances are used for manur- ing corn lands in a limited way. Refuse fish makes a good nitrogenous manure, and along the coast in places is extensively used. Green manure offers a valuable means of improving the soil for corn-growing in localities where the land has been long cultivated. This is for the reason that those cro[)s best adapted 68 INDIAN CORN CULTURE. for this purpose, such as the clovers in the North and the cowpea in the South, increase the soil fertility by returning to it additional plant food secured from the atmosphere or soil. The clover plant, it has been demonstrated, adds materially to the fertilitj^ of the surface soil by securing nitrogen from the atmosphere and holding it, and also b}^ al)sorbing and hold- ing nitric acid from below the cultivated sur- face, so that clover plowed under decidedly increases soil fertility. In the Southern States the cowpea plowed under is a recognized reno- vator of worn-out lands. According to Sir J. B. Lawes.* "the leguminous (clovers, peas, beans, etc.) are the only plants which can be said distinctly to enrich the sur- face soil when plowed in, and I may mention that in a case where a crop of red clover was grown by us, and twice mown for hay, the in- crease of nitrogen in the surface soil was suffi- cient to be measurable 1)}^ analysis when com- pared with another part of the field where the grain crop was grown." Green manure is especiall}^ valuable on light soils or heavy impoverished clay land. The crop should be plowed in at about the time of well-advanced bloom, before seed formation. The plowing under of sod or stubble is in a measure a form of green manuring, for much * The Country Gentleman, March 12. 1883. MANURES AND FERTILIZERS. 69 sod laud is plowed after the green growth has got well started. Those persons who have grown a crop of corn on land in clover or timothy the previous season have noted the in- creased yields from it, if the weather conditions were satisfactory and the tillage good. The manurial value of feeding stuffs, as iudicated by the amount of nitrogen, phosphoric acid and potash present, is shownin the follow- ing table, abstracted from a more complete table published by Dr. E. H. Jenkins, chemist of the Connecticut agricultural experiment station.* The nitrogen is estimated at 17 cents, the phosphoric acid 6 cents and the potash at 4i cents per pound.

TILLAGE. The subject of tillage inclndes plowing, har- rowing, and cultivating, and each will be con- sidered by itself in the order given. It may be accepted as true that as a rule the more thor- oughly the soil is prepared before planting the more satisfactory will be the crop returns. Too many farmers plow, harrow, and cultivate in- differently. The ground should be thoroughly pulverized before the seed is planted. This cannot be unless the plow is held back until the ground is in shape to handle reasonably well with both plow and harrow. Plowing. — For three successive years an ex- periment has been continued at the Indiana experiment station on deep and shallow plow- ing for corn. The soil is a dark, compact loam, with a deep layer of gravel about two feet be- low the surface. The usual practice at the station is for corn to follow on clover stubble, which is plowed in the spring after the clover has started growth. This corn was grown on plats permanently located for that work, which 72 INDIAN CORN CULTURE. is to continue for a term of years. Where the plowing was 10 and 12 inches deep a subsoil plow followed after the common plow and loosened to the necessary depth. The results of this work, as given by Prof. W. C, Latta,* are as follows: BUSHELS PER ACRE FROM DEEP AND SHALLOW PLOWING. Depth of plowing. 1891. 189S. 1893.

The deeper plowings gave the best returns, with that of eight inches slightly in the lead. According to the tenth census of the United States,! on the basis of the question, "How deep is the soil usually plowed for corn?" the great majority of the answers from the leading corn-producing States were from six to eight inches, some being as low as five and a very few as high as nine. In a further consider- ation of this subject Prof. Brewer says::|: "In * Bulletin 50, Vol. V, Purdue University agricultural ex- periment station, April, 1894, t Tenth Census of the United States. Report of the Pro- ductions of Agriculture, Washington. 1883, p. 98. Xlhid. TILLAGE. 73 States of gravelly or luaiiiy soils, where the yield is rarely high but is rather certain, and where corn follows clover, it is the custom with many excellent farmers in planting on such sod to plow shallow, not more than three, three and one-half or four inches deep, Imt in the after-cultivation to plow the corn in sum- mer very deep." On heavy, cold sod land, plowing a depth of five to six inches will no doubt be more satisfactory than at a greater one. On light, easily broken soil, the plow may run deeper to advantage. Under circum- stances where drouth may occur somewhat better results may be looked for from the deep plowing. Harrowing. — Having the land properly plowed, it should be reduced to a fine tilth liy the use of the harrow. On sod land a disk or cutaway harrow can be most efficiently used to tear and pulverize the overturned turf. This may be followed by a smoothing harrow that will prepare a smooth, fine seed bed. If lumps or clods occur that do not easily break under the harrow they should be broken either with a roller or plank drag. Three oak planks, each about six feet long, ten inches wide and two inches thick, chained on lap edges like weather boarding, and drawn broadside over the field, will rapidly crush obnoxious clods. Cultivating. — Even b/cfore the corn plant 74 INDIAN CORN CULTURE. has appeared above the surface it may be de- sirable to cultivate (or lightly harrow), espe- cially if v^^arm rains have occurred and the weeds are vegetating fast. Too much stress cannot be laid upon clean, thorough cultiva- tion of the growing crop. The soil should be kept well stirred in time of drouth, and at all times frequently enough to keep the weeds in TILLAGE. subjection. The farmer cannot afford to grow a crop of weeds on the kind with his corn, for not oul}' will they feed on the food which the corn should eat, but they will pump off needed soil moisture in time of drouth and interfere 76 INDIAN CORN CULTURE. with the economical handling of the crop at harvest. The frequency of cultivation will mainly depend upon the conditions of soil moisture and weed growth. If drouth prevails stirring the soil will conserve its moisture. If weeds TILLAGE. 77 occur they shonld be eradicated. For five years Prof. G. E. Morrow conducted a series of experiments at the Illinois experiment station upon the influence of frequency of cultivation upon the corn crop. The average results for the five years ending 1898 are as follows:* Kind of cultivation. Yield in bushels.

At Purdue University we ordinarily plan lor at least five cultivations during the season. At the Kansas experiment station quite a number of plats of corn have been submitted to frequent cultivation tests. The average re- sults of three years' trials, as given by Prof. ( •. C.

This loss may be due to excessive root-pruning. Where corn was cultivated, however, once in three and once in four weeks a material loss in yield oc- curred. It would appear that three to four Fig. 21. —Standard Riding Ci'ltivator With Six Shovels. cultivations a season, according to circum- stances, might l^e recommended as a general rule. Depth of cultivation should be shallow rather than deep. The roots of the corn plant, while penetrating several feet below the top of the ground, are essentially surface feeders. At TILLAGE. 79 a depth of three inches for a radius of two feet about the plant may be found a great number of fine roots. It is not desirable to cut these roots more than possible. ('()nspquently the cul- tivation must necessarilv lie shallow. 80 INDIAN CORN CULTURE. At the Purdue University experiment station Prof. Latta has found the average results of cultivating corn for six years, at depths of one, two, and three inches, to have been decidedly in favor of shallow culture, the average yields being 51.06 bu. for one inch. 50.09 for two, and 48.73 bu. for three inches." By referring back to the report on frequency of cultivation at the Illiuois station it will be noted that the shallow gave an increase of four bushels per acre over that of the deep in both ordinary and frequent cultivation. Figs. 22, 23 and 24 show three in- teresting forms of culivators specially made for shallow culture. The root-pruning of corn directly bears upon the subject of depth of cultivation. Some years ago attention was directed to this subject. In 1882, at the New York experiment station, root-pruning of corn was compared with that not root-pruned, by Dr. E. L. Sturtevant, with * Bulletin 50, Vol. V, April, 18^)4. Purdue University agri- cultural experiment station, p. 4S.

Report for 1S82, p. 53. 82 INDIAN CORN CULTURE. yield.-' Of seven comparisons all but one were very much adverse to pruning. At the Minnesota station Prof. W. M. Hays found f that the root-pruned plats averaged nearly three bushels of corn and 800 lbs. of fodder less per acre than the plats not root- pruned. Another year root-pruning was found to diminish the yield of grain 13| bushels per acre. A number of years of comparison of root- pruned with unpruned corn at the Illinois sta- tion, by Prof. G. E. Morrow, has shown a gen- eral injury from the root-pruning. J In 1893 the yield per acre was 100.3 bu. for the un- pruned as against 78.8 bu. for the pruned — a very material difference. The above results show the necessity for shallow cultivation and the injurious results of breaking off the surface corn roots. Set the cultivator so that the teeth will run shallow. The weeds may be easily destroyed by cultivat- ing at a depth of aljout an inch if the work is done in reasonable season. * New York agricultural exiieriment station.

PLANTING. 83 CHAPTER VII. PLANTING. In planting a seed numerous factors must be considered as having an important bearing on the quality and quantity of the crop. These factors will be considered under the following headings: Time of planting. Rate or distance apart of planting. Drills vs. hills. Depth of planting. Listing, Time of planting. — Necessarily two imjior- tant conditions influence the date of planting corn, viz.: geographical location and tempera- ture of soil. Brewer says" that the most com- mon rule observed as to time of planting is that derived from the Indians on the settle- ment of New England and the Middle States, to "plant corn when the leaves of the white oak are as big as a squirrel's foot," or as another saying states it, "as big as a squirrel's * Tenth Census.

There is considerable sigiiiticance in this in fact, as the oak is tardy in showing its leaves until the ground has had its spring warming. Corn not only re- quires a warm air tempera- ture to grow well in, but the soil must be reasonably warm. A temperature of the soil to a depth of one inch of from 50 to 60 deg. Fahr. will justify planting. In the great corn belt plant- ing begins about May 1 and often extends over the en- tire month. If the ground is ready it is not wise to hurry the seed into the ground too soon, as the vi- tality of the seed or young plant may be seriously im- paired by being exposed to cold rains which often fol- low stretches of warm April weather.

Every one will have to l)e his own judge for his special conditions, but it will be well to watch for the young oak leaves and note the tempera- ture of the soil. Rate or distance apart of planting. — It may be accepted as true that where corn is grown for the grain each plant should have an oppor- tunity for its fullest development. With soil of the same character and fertility it would not be best to plant an acre of the same corn in New York and Tennessee under equal condi- tions as regards quantity of seed. A less amount would do where the plants grew large and ro- bust; consequently we find a person in one latitude growing one or two stalks in a place, while in another locality, with less favorable conditions, three or four stalks are grown. At the Greorgia station, in tests as to distance of corn grown in hills, 5x4 feet apart gave the * Annual report Ohio agricultural experiment station for 1888, p. 80. PLANTING. 87 largest yield per acre. In reporting on this test Director Redding says: "The season of 1890 may be considered as about an average one, and therefore the results of this experi- ment may be taken as indicating that a dis- tance of 5x4 (or 2.184 stalks to the acre) is not too great for such land."'-' In South Carolina in experiments conducted at Spartansburg, Columbia and Darlington on distance apart of planting, the hills ranged from 5x8 to 6x3 feet, and the drills from five to six feet apart. These experiments indicated that Fig. 27.— Farmers' Favorite one-Hohse Froxt Rank Corx Drill.

As a general thing the largest yields occurred from planting four kernels in a hill, and the average yield of 69.5 bu. of air-dry corn was the greatest amount se- cured, and this by putting four seeds in hills four feet apart.f At the Purdue Universit}^ station the rela- tion of thickness of planting to yield has been studied for eight years.:]: The average results of this work show no material difference in yields where stalks are practically 11, 12 or 14 inches apart, but for distances exceeding this there is a gradual falling off in yield. In an interesting article on '"Distance apart in planting corn,*" D. S. B. of Hartford. N. Y., says:§ "The distance, after years of experiments on average soils is, in my opinion, 33 inches or six to the rod. This with good tools renders cultivation easy and rapid, and with three * Annual reports New York agricultural experiment sta- tion for 1882, 1883, 1884, 1885. t Illinois agricultural experiment station Bulletin 31, March, 1894, p. 354.

On some soils, with plenty of manure, .30 inches have given the best results, but not so invariably as IV.] inches. At the latter distance the ears will be as sound and well developed as at a greater, but not so long; at the same time there will be a larger number, making the yield the same. The fodder is much superior to that grown at gi^eater distance, stock consuming it with little waste, as it is fully developed and if cut at the proper time and properly cured makes superior feed for cows."' This probably applies to flint corn. For the large western dent corn this distance is too close. If corn is to be planted in hills, in the North as a rule 36x42 inches will prove satisfactory for the large varieties; and if in drills, one kernel every foot in drills 42 inches apart. In the South these distances may be increased to suit conditions. Drills vs. hills.— Experimental work thus far conducted indicates that it makes but little difference, so far as yield is concerned, whether corn is grown in drills or in hills. Cleaner cul- tivation can be maintained with the hill sys- tem, as the soil may be stirred on all sides of the group of plants. A field of drilled corn. however, by going up and down between the rows, can be kept creditably free of weeds and may require less labor in hoeing than will that planted in hills. In New England and the 90 INDIAN CORN CULTURE. Middle States most of the corn is grown in hills, but in the Central West and South the drill system is largely practiced. Morrow and Gardner- in 1S93 grew seven half-acre plats of corn in hills and drills, and * Illinois agricultural experiment station. Bulletin 31, March. 1894. PLANTING. 91 found practically no difference in yields. This is in accordance with previous experience. At the Connecticut State experiment station corn was planted in drills four feet apart, with plants 10 inches apart in the row, and in hills 48 by 40 inches four plants to the hill, and 48 by 20 inches two plants per hill.'*" The drilled corn gave about six per cent more dry matter and a larger yield of each food ingredient. The composition of the grain was about the same, whether hill or drill grown. At the South Carolina stations, as already noted, it made no practical difference in yield whether the corn was planted in hills or drills. Fig. 29.— CHALLENGE COKX PLANTER. Where land is fairly level, and the corn crop is an item of special importance on the farm, * Annual report for 1^00 Connecticut State agricultural experiment station, p. 18-3 92 INDIAX CORN CULTTRE. on well-prepared laud the drill system will be most economical in rapidity of planting and cultivating. This means, of course, that a modern horse corn-planter shall be used. Depth of planting.— On warm, light soil, the seed should be planted deeper than where it is cold and retentive. The process of vegeta- tion is slower on cold than warm land, as the temperature is lower at the same depth below the surface. In summer if a drouth occurs the greater depth of planting on the light soil is beneficial to the growing crop. If a low" river bottom is the corn field, shallow planting will do, as crops rarely suffer from lack of moisture in such a location. Generally speaking the w^riter believes one and a half inch a satisfactory depth to plant the seed. As bearing on this subject, the following table of results of experiments on depth of planting, conducted at the Ohio and Illinois ex- periment stations, is of interest.* The Ohio experiments are average results of six years' work (1SS3-1SSS) and those of Illinois of five years' duration (18SS-1S93): * Bulletin No. 31, Illinois station, March, 1894, and seventh annual report of Ohio station, for year 1*^88, p. 81.

It is important to note, however, that the Ohio "corn planted three and four inches deep seemed to retain its vital- ity longer than that planted at less depth. The roots of the deep-planted corn were found, as we should naturally expect, much deeper in the soil than wdiere the corn was planted more shallow; hence their opportunity to secure food and moisture was materially enhanced." The experiments in both States were conducted on deep, retentive soils. 94 INDIAN CORN CULTURE. Listing. — The listing process is peculiarly a Western one, practiced on the big corn fields of Iowa, Kansas, Nebraska, and the other great corn-growing States west of the Mississippi. In 1886 the Farmers'' Review pul)lished* a number of articles on listing, one of which, by Nelson Cowles of Dakota City, Neb., is so clear in ex- plaining the process that it is inserted here in the main: "The libting plow consists of a double share and mold board, or a i-ight and left-hand plow, so joined together as to Fig. 30.— Listing Plow. turn the soil both ways from a common center. Attached to the plow is a small subsoiler which loosens the soil in the bottom of the furrow. There are two classes of the different makes of listers, the single and the combined. When the single lister is used a common Hoosier drill follows the plow in the furrow and plants the corn. In the combined imple- ment a drill is attached directly to the plow, thereby saving the labor of an extra man and horse, and if the implement is properly constructed works equally as well. "There are methods of listing corn known as 'single' and 'double" listing. In the single method work is not com- * Farmers' Review, April 21, 1886. PLANTING. 1)5 menced until planting time, when the HsIlm- is used in the iiollows Of middles between the old corn rows, or else on fall- plowed land, where the lister is run through the field from three to four feet apart, according' to the soil, kind of corn l)lanted, and judgment of the operator. The single method seems better adapted to sections of uncertain rainfall, being only one-half the labor of the double plow, which is as fol- lows: As soon as the stalks ai-e cleared from the field in the spring, the listing plow, with drill removed, is put at work splitting the old corn rows, thus filling the middles and form- ing a new i-idge therein. This preparation gives drainage and opens the soil to the warming influence of the sun. Then when planting time comes the drill is attached and the new ••idge is divided, and the corn planted in the furrow thus made, the drill dropping the corn, one kernel in a place, from S to 20 inches apart, as the operator may choose. By this l)lan more thorough tillage is secured. * * * '"In cultivating after the corn is up the field is gone over with a planker, or what is far better, a smoothing harrow, which smoothes the ridge and jirepares the ground for the cultivator, which is used with but one shovel on each side of the i"ow the first time and both shovels afterwards." Concerning the merits of listing there is much diversity of opinion. At the Kansas ex- periment station this practice has been com- mended on the basis of experimental returns.* Four plats listed, compared with four given surface planting, showed a small gain for the former — about- four per cent. At the Minne- sota station results somewhat nnfavoraide to listing were secured in ISSS.f Francis Mc- * Kansas agricultural experiment station.

TLANTING. 97 Keiizie, in the Farmers' Jierieir (April 21, 1886), states that he believes listing is of doubtful utility excepting in veiy sandy land where the rainfall is deticient. On ordinary prairie land he prefers the standard method. Another writer in this same journal expresses no faith in listing- where there is abundant moisture and heavy soil. Prof. Georgesou of Kansas says:* '•Deep plauthiy- by the use of the lister is undoubtedly the best means to tide over a drouth. Here in Kansas, where the rainfall is somewhat uncertain, the majority of the farm- ers list their corn, and in a dry season listed corn frequently yields a fair crop when surface-planted corn is a failure. The roots of listed corn are not so near the surface and they there- fore do not feel the di-outh so severely. For this same rea- son listed corn can be cultivated deeper with impunity. But the lister cannot be used to advantage everywhere, espe- cially where, the rainfall is usually sufficient to supply the needs of the crop. In such i-egions listed corn would be liable to be drowned out unless the soil was well drained: Again, on stiff clays listing cannot be practiced with the same advantage as it can on the black prairie mold." Mr. J. ^[. Boomer of Kansas says in the Breeders Gazette (Fel). 13, 1895.) that he has Ijeen listing corn for fifteen years, and nine- tenths of the corn in his neighborhood is listed. He plants with a single-horse drill, dropping the kernels 15 inches apart. He prefers a sin- gle drill to a double one, because if the rows are not just the right distance apart the two- * Indiana Fanntr. June .■'.0.

He prefers listing to plowing the ground and planting on top, as it is more easily done, the land is more easily cultivated, and consequently it is cheaper to raise it in this wa}^ The corn stands the drouth better, does not blow down like top-planted corn, and yields more per acre. The advantages claimed for this process are: (1) economy of labor, (2) more thorough tillage, (3) ability of the crop to withstand drouth, and (4) increase of crop. 99 iTiiiii Alt W' CHAPTER VIII, HARVESTING. The general results of investigation indicate that when the kernel on the ear has become glazed or hard on the surface, even though somewhat soft within, it contains as much nu- triment as it will possess at any time. Further ripening does not seem to material!}' affect the grain composition. Time for cutting. — In experiments at the Iowa station* five plats were cut at periods varying from Sept. 17 to Oct. 13. Plat I was cut when the kernels were ^'in the dough," not quite all dented, and leaves green; plat II, ker- nels well dented and leaves just beginning to dry: plat III. kernels ripened and blades about half dry; plat IV, kernels thoroughly ripened and blades and husk rapidly drying up; plat V, blades and husk nearly all dry. There was no noteworthy difference in crude protein in the dry matter between the first and last cut- * Bulletin 23, Iowa agricultural experiment station, 1893, pp. 874-880. 100 INDIAN CORN CULTURE. ting. The widest variation in per cent of car- bohydrates was less than one per cent, while there was a slight increase in fat from first to last cutting. In any case the feeding value of the corn does not seem to be affected. As might have been expected, the corn-fodder was in- jured in quality by delaying cutting after the grain was mature. There was a depreciation in crude protein in the fodder from 8.47 in plat I, to 4.05 per cent in plat V, and this loss in- creased from week to week. Fodder that was left uncut in the field till December was ma- terially damaged. There was also a great loss in fat, this per cent falling from 1.11 to 0.29 per cent. There was something of an increase in crude fiber and carbohydrates, but this would not affect the loss of the more important food components. The largest amounts of dry mat- ter from an acre, 6,7S2 lbs. in fodder and ker- nels combined, was secured from the second cutting. Among the conclusions reached, as based on this study, are the following: • ''(1 ) The stover of a crop of corn seems to reach the high- est yield and the best condition for feeding at tlie stage of growth indicated by a well-dented kernel and the first dry- ing of the blades. (2) The grain of a crop of corn seems to reach the highest yield and the best condition for utility at the stage of growth indicated by a well-ripened ear and half- dried blade, and the best time for securing the crop with reference to the highest utility of both corn and stover would be found at a stage of ripening between the above." HARVESTING. KM These general results luid conclusions are such as have been accepted on the basis of pre- vious investigations. At the Kansas station corn cut in the milk stage (Aug, 20) yielded '>').5 bu. grain and 2.4 tons of fodder per acre; in the dough (Aug. 28), 51 bu. grain and 2,4 tons fodder; when ripe (Sept. IS), 74 bu. grain and 2.7 tons fodder.* These results agree with work at that station for the three years in suc- cession. Cutting for silage. — Where corn is cut for silage the crop should l)e harvested when well glazed or dented. At the Minnesota station, where corn grown for silage was cut from Sept. 4 to 24, the dry matter in a dent variety in- creased from 11.4 to 19.7 per cent, and in a sweet variety from 9.1 to 13.3 per cent.f At the New York State station the dry matter per acre in B. «t W. corn cut for silage Sept. 11 was 0,004 lbs., and on Sept. 29, 5.660 lbs. In 1889, with King Philip corn, there was an increase in the total amount of dry matter and in the nutritive value of its constituents as the crop approached maturity.:|: At the Cornell Uni- versity station similar returns were secured * Kansas agricultural experiment station, Bulletin No. 30. t Minnesota agricultural experiment station, Bulletin No. 7.

In an interesting experi- ment at the Pennsylvania station by Hunt and Caldwell, to ascertain the food value of corn -fodder cut at dif- ferent stages of ripeness, of three cut- tings (Sept. 1 and 2, Sept. 25 and Oct. 7 and 8), the best results came from that cut Sept. 25, Cows fed on me- dium mature corn-fodder produced the largest quantity of butter-fat at the least cost, the late-cut fodder gave the next best returns, while the early- cut made the poorest showing.:}: Methods of cutting. — At the pres- ent day most of the corn cut for the silo or for shocking is cut by hand with a corn knife. In the West a popular knife has a straight blade (see Fig. 32) about 20 inches long, two inches wide, and rather heavy on the back. In the East a knife with ; iscon- flint fhtly- *Cornell University agricultural experiment station, Bul- letin No. 16. fV^isconsin agricultural experiment station. Annual re- port for 1889, p. 126.

HARVESTING. 108 curved blade, set iii the end of a short handle, bhide and handle forming an obtuse angle, makes a favorite hand knife. Some people use a grass hook or sickle from preference. The straight-bladed corn knife is unsurpassed for rapid and effective hand work. Corn-harvesting machinery.— Within a few years nuKdiines have been devised for cutting corn by horse power. One method has been to haul l^etw^een two rows a di-ag with wings on one or both sides, to which knives are attached. The Buckeye machine (Fig. 33) is one of the most approved types of this class. It is carried on four wheels and is pulled b}^ one horse. In the center of the machine is a tripod with a seat on which two men may sit, one on each end and back to back, each facing a row of corn and grasping the stalks as cut. When not in use the wings with knives may be laid up against the tripod. The knives adjust to leave stubble 6 to 14 inches long as desired. The self-biiuling form of the harvester, how^- ever, promises to be the important one of the future. In the Biiral New Yorher of June 20, 1891, Prof. I. P. Roberts of Cornell University described a machine he devised for cutting and binding corn. This machine was improved by D. M. Osborn & Co. Since then a number of firms have placed self-binders on the market. The Deering Harvester Co. construct a machine 104 INDIAN CORN CULTURE. Fig 33.— Buckeye Corn Harvester. FIG. 33 a.— The McCobmick Corx Binoeb. HARVESTING. Kl.") which runs on two 3S-inc'li wheels. Two wide gatherer arms embrace a row of corn and guide the stalks to the point where they are cut while standing npi'ight, being pressed against a long, sharp shmting knife. The corn is seized b}^ the strong fingers of a rotary ledger plate and pressed against a long beveled knife. As soon as the corn is cut it is taken up by gatherer chains and laid on the binding deck, tassels backward and bound and discharged, the bun- dles being tossed off lengthwise between the wheels. The McCormick Harvesting Co. also make a self-binder (see Fig. 33 a) that is being used with mucb success. The stalks are cut off near the ground and carried in a vertical position to a modified form of the common self-binder, wdiere they are bound in bundles with the butts square and in good shape for shocking. The bundles are thrown off to one side. Ordi- nary binding twine is used. The machine is adjustal)le to short or tall corn and may be tilted up or down to pick up sprawling stalks. The McCormick and Osl)orn machines in a trial at the Indiana experiment station did very sat- isfactory work. There has within the past year been a large sale of these self-binders. The Deering Co. state that they are unalde to supply the de- mand, and the McCormicks have sold more than 106 INDIAN CORN CULTURE. 10,000 machines since making their exhibit at the Columbian Ex^DOsition. Where corn culture is engaged in to an ex- tensive degree the self-binding harvester is a great labor-saving machine, while where less corn is grown the simpler knife harvester can be used to advantage. In hauling silage corn or fodder a low-down wagon is a great improvement over the high wheels. Fig. 34, re-engraved from the Country Gentlemcou represents a method of carrying a load close to the ground. It is made by insert- ing a reach 20 feet long, made of a round pole bending down with a foot curve. Closely under the axles two stiff timbers over 20 feet long are chained to the axles, and cross pieces 7 feet long are spiked on them to support the two lu'oad boards or planks which are outside the wheels. A platform is thus formed 7 feet wide, over 14 feet long, only a foot above ground. Small wheels may also be bought for common axles, replacing high wheels. Shocking the corn. — The number of hills or amount of rows which may be placed in one shock to best advantage depends upon the class of corn, whether large or small. If grown lIAin'KSTrNG. 107 in hills, and of niediiiin-sizod plants, ten bills square (100 hills) will make a good shock. Of smaller corn, 144 hills may be j)ut into a shock^ while of very large corn 81 hills makes a plenty. Yet there is a difference of opinion on this sub- ject and many place over 100 hills of fairly large corn in one shock. However^ a medium- sized shock cures out more rapidly than a large one and the ear becomes fit for storing at an earlier date. Where corn is grown in drill rows about 40 feet each of eight rows will give material enough for a good shock. A medium-sized shock should have a circumference at its base of about 25 feet. Anything much over that might be termed a large shock. Where wheat is to be sown in the corn rows the shocks should be larger and further apart. Under such circumstances they should be as large and as far apart as economy of labor in construction will permit. Waldo F. Brown, in writing of his new method of shocking on wheat seeded corn land, saj^s:* "We cut the corn and put 10 rows in a shock row, but only eight hills the other way, and in a few days when the corn has dried out so as to reduce the weight about one-half we carry one shock from each side and set around the middle one, which gives us 240 hills to a shock and makes our shock rows 30 rods apart. We do this handling in the morning when the dew makes the fodder tough to handle, and as the * Farmers' Revieti\ Sept. 26, 18S8. 108 INDIAN CORN CULTURE. fodder is partly cured we can make the shocks this large without danger of their moulding. If wheat is not sown I prefer 100-hill shocks and husk them as soon as cured,"' Careful shocking necessary. — In shocking it is important that the shock be set erect and hekl firmly in place until husking, so as to keep the contents dry from rain and not retard proper curing of both fodder and grain. A shock that has been blown over and well soaked with water is materially damaged. If the shock is properly placed about one uncut hill, or two hills with plants bent part way Fig. 35.— Corx Hobse. over and twisted together, it should not blow down. Care should be taken to place an equal amount of stalks on each side of the shock. If the central hill is cut a corn horse may be used to advantage. This is made by taking a piece of timber 2x4 inches by 12 feet, on one end of which are nailed two legs about three and one- half feet long. An inch hole is bored about five feet from the raised end, through which is loosely inserted, horizontally, a round cross piece. An old broomstick will do nicely. Charles E. Benton, writing of the corn horse, HARVESTING. 109 says:* "Where they [the legs] join the main piece, as shown at a in Fig. 'So, I have naih^l on some light strips in such a way as to form a little cage or box in which corn ties are carried, each one with its string snugly wound on its block." The stalks are placed against the corn horse, when the cross stick forms four corners, and the shock is built here. When it is com- pleted the cross stick is pulled out, after wliich the horse is withdrawn. Tying the shocks. —After the shock is formed it is tied near the top. A rope with a pulley on one end may he used to advantage for draw- ing the cornstalks together tightly near the top, after which the tie may be placed on the shock. Rye straw .cut in the bloom makes ex- cellent tie bands. Cornstalks theuiselves are too l)rittle. Binding twine is strong enough, Init may 1)6 cut by mice. Tarred twine is strong and is not cut by mice, and may be rapidly tied so as not to slip. When economy is to be considered rye straw is about as satis- factory a cheap tie as can be secured. \n Western Xew York \villow twigs are popular bands. Stacking.— To stack to best advantage, or to handle on the wagon or elsewhere, the corn should be placed in small bundles and tied at the center after curing in the shock. If string *Amencan Ayricultui-ist, Sept. 1, 1894. 110 INDIAN CORN CULTURE. is to be used for binding it will expedite work to cut it into suitable lengths before getting into the field. The stack should be located in a convenient and well-drained place and have a foundation of straw, rails or boards, to keep the fodder dry. The base of the stack should have a di- ameter slightly less than the length of two bundles of stalks laid end to end. The butt ends of the stalks should form the exterior of the stack and the center should always be from two to three feet higher than the outside for that layer of corn. The diameter in well-made stacks slightly increases up to a height of six or eight feet, after which it may contract until topped off. As the stack is built bundles are laid crosswise over each layer about and at the center and over the ends of the bundles form- ing the outer layers, to keep the whole well bound together and to maintain a sufficient slope to the stalks forming the outer circum- ference of the stack. When the top is to be formed the stalks may be gradually drawn in and all the bundles placed in layers sloping from center to without, so as to furnish good protection for the fodder below. Sometimes the stalks are laid up to a pole five or six feet long, inserted in the top of stack, to which the bundles may be fastened. Such a covering is not easily displaced by the wind. HARVESTING. Ill Small stacks are preferable to large ones — from 50 to 100 shocks to each one. Such a size can be haiidled to better advantage than a large one, whether the fodder is fed in field or stable. Pulled fodder is especially prepared in the South. This operation is well described by "H." in the Coimfnj Gentleman of Feb. 5, 1885: "There are usually two stalks in a hill of corn; the blades are gathered as high as the operator can reach, from both stalks, and thrust between them to remain until dry enough to bind into bundles, which are as large as the blades will reach around and tie. This tying is done very late in the evening after the dew begins to fall, when the corn blades, thoroughly dry, are just moist enough not to crumble. The fodder has then to be packed [carried] by hand, either to the ends of the rows, where it can be hauled to the barn, or if the rows are very long, to some central point to be stacked, not in loose leaves, but in bundles." This method of securing fodder is becoming less and less practiced in the South. The cost of fodder so secured is too great and valuable food material is lost in the stalks left in the field. As a practical business matter the Southern farmer should cut his corn within six inches of the ground and cure it in the shock, as is done elsewhere. The practice of topping corn is equally as undesirable as pulling. Husking. — In the eastern United States where the weather is somewhat uncertain in the fall, and snow comes early, the corn is usu- ally husked as soon as diy enough. The ears 112 INDIAN CORN CULTURE. are often pulled from stalks with husks on and carried to the barn, where they may be husked at leisure, or stalks with ears on are placed in shelter, with the husking to follow later. In the great corn-growing States, where less rain occurs in the fall than in the East, field husk- ing is more easily accomplished. Where the corn is not cut and shocked, deep box wagons drive through the immense fields when the corn is well dried, and the ears are pulled from FIG. Sti.— t'lNGEK Husking Pin. the husks and thrown into the wagon and con- veyed directly to crib or market. Where the corn is shocked, after curing the ear is husked and usually thrown into heaps in between the rows, or into wagons, and the stalks placed back into the shock. Several average-sized shocks of husked stalks are generally combined to make one very large one. Dispensing with husking. — In an article in the Rural New-Yorker published about 18S8 Prof. Sanborn favors dispensing with the husk- ing process, on the basis that it involves a three- fold cost, viz.: "First, labor, which is a variable amount, depending- upon HARVESTING. 118 whether the fodder is saved and the method hy which it is saved. If the fodder is not saved the cost will be three cents a bushel for husking and cribbing, and on the assump- tion that coi-n sells for 30 cents a bushel, * * * then the food must be 10 per cent more effective simply to repay us for the cost. If the fodder is saved the cost of husking will be doubled and 20 per ct-nt will have to be added to the efficacy of the food to balance the cost of the process, and more must be expected if a pi-ofit is to be received. The second additional cost will be the loss of leaves, as the result of husking in the field after the fodder is partly dried. This loss is a material one and involves the most digestible pai-t of the food. It is difficult to estimate the value of this cost, but when added to the third loss, or the risk of the influence of rain with its leaching effect on the fodder through neces- sary-delay in housing the fodder while husking the corn, it is safe to say that $1 per acre is involved, or two to three cents a bushel of corn."

However, where grain is to be sold in the market, and certain classes of feeding are to be done, husking is necessary. Husking machines.— For several years husk- ing machines have l)een manufactured that do HARVESTING. 115 a very satisfactory class, of work. These are quite expensive and are usually owned by parties who go from place to place husking the crop at so much per bushel and shredding or cutting the fodder at the same time. The Key- stone husker and shredder (Fig. 38) and the St. Albans shredder (Fig. 39) are two of the prom- inent shredders on the market, and the manu- facturers of the Keystone thus explain its operations: "The stalks are fed to the machine with the ears of corn on. The feed rollers crush the stalks thoroughly and pass them on to the knives, which cut them into fodder, or to the shredder head, which tears the fodder into fine shreds, leav- ing it in very much the same condition as hay. The fodder elevator then carries it to the mow of the barn or to the shed or stack. The feed rollers do not crush the ears of corn, but simply snap them off the stalks. The ears drop to the husk- ing rollers beneath the feeding platform, where the husks and silks are taken off. The husks and silks are passed out with the fodder and the ears of corn drop to an elevator which delivers them to the wagon or crib."' This nuudiine is a great invention, and in large corn-growing disti'icts sliould ])e an im- portant factor in the econ(jiny of handling and saving the crop. The husking is done as well as is usually done by hand. Shredding. — ^The shredded fodder will keep satisfactorily in the mow if well dried when put in, but if it is damp it will mold. Care should be taken to avoid shredding damp fod- der. This material is very valual)le for feed 116 INDIAN CORN CULTURE. and is being regularly sold on the market. At Lafayette, Ind., the writer has purchased it at the feed store for $5 per ton, while in some other places it fetches $S. In view of the fact that so mu(di corn-fodder goes to waste in the field the shredders offer a valuable medium of rescuing it and placing it on the market in a desirable form for economical feeding. Says the Breeder's Gazette (Aug. 15, 1S94): "That the invention of the shredder opens up a mar- ket for an almost unlimited quantity of foddei', shredded and baled (see Fig. 40), for city trade, is beyond all question. It will soon be quoted regularly in city feed stores " * ^' and we are informed that a bright, well-cured quality of shredded fodder has sold in bales at city feed stores at $8 per ton.'' Testimony concerning shredded fodder.— During the spring of l!S95 the Ih'eeders Gazette published many interesting letters from exten- sive corn growers and stockmen who have shredded their dry corn fodder. The universal testimony seems favorable to this method of preparing the dry plant for feeding. The shred- ded material may be stacked in the lot, after the manner of stacking hay, though it is prefer- able to place it under shelter. The following evidence is abstracted from the various communications in the Gazette as presenting valuable information on a compar- HAi;\ ESTING. 117 atively new process of preparing i-ou;^^li food: Wulff Bros, of Nebraska say: "Corn to be shredded ought to be cnt just as soon as it is out of milk, and it will shred and handle the best if it is left in the field. It keeps all right if ricked outside with shed roof over it, but it will heat and mould if not bone dry if it is put 118 INDIAN CORN CULTURE. ill barn and in great bulk." H. L. Buschling of Missouri thinks that if entirely dry when shred- ded it will not mould if put in barn in great Inilk. With him the shredder has given entire satisfaction, Sauiuel Senneff of Illinois writes: "I have stacked it outside and it kept well. It packed so solid the water did not run into it. I would prefer having it under roof, fV>r it is easier to handle during the winter storms." In reply to the question, ''Is it not likely to mould and spoil if put in great bulk.^" Mr. Senneff says: ''It will not if it is fully cured and diy when shredded. I have put the fodder from 40 acres in a barn and it has kept well. I am now feeding to my stock fodder which wns cut last Octol)er and it is bright and dry." (1. H. Robinson of Vermont cuts his corn when ripe, shocks it and lets it stand till the fodder is dry. Then he husks it, after which the stalks are drawn to the barn, shredded, and placed in the mow. He has never had any mould or spoil, and the larger quantity he gets together the better it keeps. The complaints of this shredded material be- ing spoiled by moulding are very rare, and it is generally agreed that if the stalks are fairly dry when shredded they will not spoil in the heap. While heating sometimes occurs, in the experience of the writers the effects do not ap- pear detrimental. In no case is a record given HARVESTING. 119 of spontaiicuus coniljusLiou occun-Jiig froiu ovei'-heating. 'I'lie intlications are that the shredding of dry mu. _j coru-f odder will become a popular and econom- ical method of preparing it for winter feeding. 120 INDIAN CORN CULTURE. The shredders handle from three to ten acres of corn a day, according to size of machine and character of crop. The prices of shredders are listed at $80 to $130, and of huskers and shred- ders combined at $150 to $400. Threshing corn is frequently practiced where threshing machines are common and the crop is large. A common threshing machine is used. W. J. Bingham of South Dakota says:* "I have threshed it for the past five years, more or less, using a Westinghouse Separator. It is just as easy to thresh as wheat. Leave the cylinder the same as for wheat, and take out all the concave teeth but one single row, putting in blank concaves or boards to fill out. Run the machine about half as fast as for threshing wheat; this will crack the corn some but will not hui't it for feeding purposes. I think this is a superior way of handling corn, especially where you .use a binder and bind corn the same as wheat. The fodder is almost equal to that cut by a fodder cutter, and will keep here in Dakota in stack without being covered with anything, but where they have more rain top with marsh hay and it will keep all winter." Where threshing is practiced the corn must be well dried in the field, else the grain will heat in the bin or pile. * Breeder's Gazette. Oct. 10, 1894. ROTATION OF CHOPS. 121 CHAPTER IX, ROTATIOX OF (7?0PS. Numerous factors demonstrate the necessity of gi-owing different croj)S on the same land during a period of years. Agricultural plants differ in their root development and conse- quently in their feeding capacity. The clover plant is a vigorous feeder and sends its roots over quite a range of territory, while tlie sugar beet develops its roots to a mufh more limited extent. Rotation rests the land.— A\ e know that rotating crops rests the land for some reasons which cannot be entirely explained. Farmers know that red clover can be grown satisfac- torily only a year or two on the same field, when the land becomes what is commonly termed "clover sick." Says Sir J. B. Lawes:* '"Land will also become sick of any other leguminous crop if grown too often; but it is a most singular fact that where one leguminous crop ceases to grow another will thrive. We had a remarkable instance of this in one of our fields which was bean sick, and as all our endeavors to grow this crop were in vain we at last decided to give up the attempt, and * Country Gentleman, March 12, 1885. 122 INDIAN CORN CULTURE. in place of the beans we sowed barley and x-ed clover together. The result was that the red clover sown with the barley was so luxuriant as greatly to interfere with its growth, and this too upon land where we had been trying to grow beans with- out manure for 30 years. In spite of our having grown a leguminous crop something had accumulated in the soil which was more favorable to the growth of another legu- minous plant than to that of a cei'eal crop." Pkiiits also differ in use of ingredients of soil fertility. Tobacco is notably a potash feeder, while the clovers use coniiDaratively more nitrogen than phosphoric acid or potash. This being the case, one kind of plant food might 1)0 accumulating in the soil while a crop was l)eing grown upon it which made only a slight drain upon that particular element. If no ma- nure was put upon the land it is plain, in view of these facts, that the land could be cropped to better advantage by the rotation system than by continuously growing the same class of plants on it. An important factor in rotation also beai's on the plant food left in the roots of the crop last removed from the field. Gulley states* that when either red clover or cowpeas are grown on land of average fertility in the South after cutting off the crop for hay the stubble and roots on an acre of soil contain as much nitrx)gen, phosphoric acid and potash that may become available to the next crop as a dressing * First Lessons in Agriculture, 1892, p. 85.

Importance of rotation recognized. — In the rotation system tlie fart must not ]>e lost sight of that the soil may be kept free of weeds to the best advantage. Grass laud, followed by a hoed crop, permits clean cultivation. The importance of rotation is recognized to- day by the practical farmer, even though he may not understand the principles underlying the practice. In experiments at the Purdue I^niversity station very notable gains are shown in favor of rotation as applied to Indian corn. An experiment was begun in ISSO to com- pare different systems of cropping without using manures. On one series of plats grain is grown in succession year after year, or two crops alternating with each other, these crops being corn, oats, wdieat. On another series of plats the same crops have been grown in rota- tion with clover or timothy. The yields of corn on the two series for 1898, and the average yields for the last six years, as given hj Prof. W. 0. Latta, are as follows:* 1S03. Average for 6 years.

As no manure was used the yields are natur- ally small, but the balance in favor of the ro- tation is a large percentage. For 18 years rotation tests have been con- ducted on corn at the Illinois station. ■'^ Where corn, oats and clover were grown in rotation a decided gain in yield of corn was secured over those plats which did not receive a dressing of commercial fertilizer, that were not in rotation. Systems of rotation. — There are numerous rotations including corn which are satisfactory. On the Purdue University farm a rotation of corn, oats, wheat, clover sown on wheat in early spring of third year, and cropped fourth and fifth years, proves quite satisfactory. To favor large cropping stable manure is well dis- tributed over the clover stubble before it is plowed in. The corn has a fertile field and its cultivation cleans it of weeds in good shape for the crops wdiich follow that receive no hoeing. The oat plant is a gross feeder, and following after the corn it finds the ground well enriched with the available food in the roots and stubble and the manure i)reviously applied. For the Southern States where red clover will grow, Gulley recommendsf the following five-year rotation: Corn; clover on corn stub- * Illinois agricultural ex2)eriment station, Bulletin No. 30, p. 357. t First Lessons in Agriculture, 1892, p. 86. ROTATION OF CROPS. 125 l)le ill spring; clover; oats followed by cow- peas the same year; cotton. Either the cotton or oats may be left out, and a four-year rota- tion be adopted. To secure the most economical and profit- able cropping of the farm the practice of a judicious rotation is absolutely essential. This fact can easily be demonstrated in noting the practice of successful farmers. 120 IXDIAN CORN CULTUKE. CHAPTER X. INSECTS. The lourpose of this chapter is to describe briefly some of the more injurious insects affect- ing the corn plant or its seed and to suggest remedies with which to suppress them. The descriptions and remedies are those given Ijy economic entomologists of high standing, and more especially by Prof. F. M. Webster, ento- mologist of the Ohio experiment station; Dr. J. A. Lintner, New York State entomologist, an<] Prof. S. A. Forbes, Illinois State entomologist. From a valuable paper by Webster on "Insects Affecting the Corn Crop" * numerous important descriptive abstracts were made. The State reports of Forbes and Lintner were also freely used. Injuring seed after planting. — Tlte seed earn fiij {PJiorhia fusicejjx, Zetty). This is a yellow- ish-white, footless maggot, about one-fourth inch long, blunt at posterior and pointed at anterior end. It feeds on the substance of the * Report Indiana State Board of Agriculture, 1885, pp. 180-215. Fig. 41.— Wire Woum. INSECTS. * 127 swollen kernel in the ground. It lias not proved very destructive. A tarring of the seed before planting will doubtless keep off the maggot. ]]l're iroruts {Elateridw). These are the larvae (grubs) of the common snapping beetles, of which there are many species. These worms (Fig. 41) are greatly abundant only in new- ly-plowed meadows. They eat into and destroy the kernels of corn or eat off the germinating shoot or roots. Lintner says the best preventive in infested fields is starving out by crops of buckwheat or peas.'*^ Fall plowing of sod land is thought desiral)le by many farmers, the grubs being disturbed and ^'^- *=^- wl1elow the head. When they reach full growth the worms leave the root, crawl to one side in the soil, make a cell there, and transform into white pupa (grub stage), which soon changes into the beetle form. This insect has done great damage in our corn fields, especially in the Central West. In 1885 Prof. Webster noted damage to the corn crop of Moses Fowler of Lafayette, Ind., amounting to 15 per cent of the entire crop on 10.000 acres— a total loss of about $16,000. '^ A rotation of crops is a satisfactory method for preventing damage from this insect, as has been demonstrated on a large scale. Wheat or oats may be suiistituted for the corn crop, as this insect cannot secure food from their roots, they being too woody and tough. The first crop of corn on grass or clover sod is not usu- ally injured by this pest, although numerous cases have occurred where the corn was injured on clover sod. Report Indiana Board of Agriculture for 1885, p. 188. 130 INDIAN CORN CULTURE. White grub {Lachnostenia fusca, Frohl). This is the larva of the common brown May beetle or June bug. The beetles deposit small, whit- ish eggs about the roots of grass which in about a month hatch into small, brown-headed grubs that feed on the roots about them. During the second year the grubs w^ork near the surface and reach their full growth during the spring of the third or fourth year. They are most abundant in old grass lands, and wdien this is plowed for one or two seasons may work great damage to the corn wdiich may be planted on it. This is a difficult insect to exterminate. Fall plowing is no douljt advantageous. Pasturing land in the late summer and fall with pigs will be a means of getting rid of manj^, then plow- ing during the late fall or spring. Affecting the stalk.— Cut nanus. Cut w orms are of numerous kinds, all of which belong to one special group — the Noduidce. The follow- ing are characteristics common to nearly all the species, according to Lintner.* FIG. 44 -GLASSY CCT WORM. Larva ^^^^^^^ f ul 1 gl'O WU, CUt of Haaenaaetastamx.

In form they are stout, tapering slightly toward the extremities. In appearance they are usu- ally dull colored, greasy looking, dingy brown, gray or greenish, with some light and dark longitudinal lines, and sometimes w ith oblique dashes. They have a large, shining, red or red- dish-brown head. The first ring or collar ))ears a "darker-colored, shining, horny plate, as does also the last one, known as the anal plate. The body is never hairy, but the several rings have upon each six or eight small, blackish dots or humps, from each of which a short hair is given out. The cut worms do most of their feeding at night, during the day Fig. 45 —Moth of Cut Worm shown Y i • i i i ,1 in Fig. 44. (After Kuey.) beiug hidoeu ueueath stones, sticks and rubl)ish. Some cut w^orms feed on the parts of the young plant above ground and some below. The parents of cutworms are moths. These deposit their eggs on a plant near by the feed- ing ground as a rule, although they are also placed on fruit trees. The eggs soon hatch, when the young worms drop to the ground 132 INDIAN CORN CULTURE. and enter it, where the}^ feed. Later they go deeper into tlie soil and remain there over winter. In spring they come to the top soil again and feed. In a few weeks they become full-grown worms, when they make cells in the soil, in which they locate and where they undergo a change to pupa, and soon after de- velop into the moth. / KiG i6.— Moth OF Dingy Cutworm Agrotis subgot/iiro. (After Kiley) About 12 kinds of cut worms are especially prevalent on corn. On new sod ground the cut worm is most frequently found. Numerous methods have been tried to pre- vent the ravages of cut worms, but as a rule they are more or less unsatisfactory, Lintner recommends the use of a tablespoonful of salt scattered over each liill of corn."-^ He says this method has been used with considerable suc- cess. The explanation of this protection is that the salt dissolves and is taken up by the roots into circulation and makes the food un- palatable to the worms. It appears to the * Eighth report, etc., p. 239. INSECTS. 133 writer that great care should be used iu apply- ing this salt, as too much will certainly kill the young plants. Lintnor also notes* that a gen- tleman who soaked his corn in copperas water hefore planting was not troubled by the worms. A bushel of coi'n is placed in a tub and covered with water, and a pound or pound and a half of copperas water added^ which has been dis- solved in warm water. This is stirred among the seed, which are al- lowed to soak 24 to 30 hours. Prof. J. B. Smith recommends the use of kainit (a potash salt) to prevent cut- worm ravages.-}- Ex- periments of his gave favorable results. The kainit should be broadcasted over the field just before planting, as in spreading fer- tilizer, for such it also is. Riley, Fletcher and others have recommended the poisoning of green grass or clover and placing it in bunches about the fields. The cut worm will Ite killed Fig 47.— GKEASYoii Black Cpt Worm, Agrotia ypsilon, Hatt. a, cut worm; b. head of worm from front; c, motb.

This should be done just at nightfall. Stalk horer {Gorfyria u'dehi, Cluen). A full- grown worm is a little over an inch long, bluish- Ijrown above, with three white lines on the back, the central one continuous, the others interrupted for a considerable space at the middle.* This worm is the product of eggs laid by a moth on grass or earh^-planted grain. When the eggs hatch the worm crawls down ± z Fig 48.— Stalk Borer, Goriywa ;(i7Wo.Guen. 2, moth; 2, worm. (After RUey.) into the stem of the plant. To prevent their ravages, Webster recommends f one ounce of pyrethrum powder in two gallons of water, or one part crude carbolic acid to 100 parts water. Spray or sprinkle the j^oung plants so this liquid will run down among the unfolded leaves. Chinch bug {Blissns Jeucopterus, Say). This is a true bug that is about three- twentieths of an inch long and one-third its length in breadth. * F. M. Webster: Bulletin 3, Purdue University, April, 1885. t Report Indiana State Board of Agriculture, 1885, p. 192. INSECTS. 135 The body is black iiiid slightly hairy as seen under a microscope. The wing covers are white with a sub-triangular black spot in the middle of the outer margin of each and a few black veins upon their middle. The feet, claws and enlarged ends of the antenn-te are black, while elsewhere the antennae and legs are dull yellow. The chinch bug deposits at least two sets of eggs, one in the fall upon the crown or the roots of plants, and another iji spring. The eggs are very minute and one bug deposits about 500 at inter- vals extending over several weeks. The eggs hatch in about tw^o weeks. At first the larva is pale yellow, but changes to red, except the two anterior segments of the body, and the legs, which are yellowish. After the first moult it becomes bright red with a pale band across the middle of the body. After the second moult the wing pads begin to show and the general color gets darker, with the pale band still con- spicuous. A third moult develops the pupa with distinct wing pads, the anterior portions being dark l)rown and the abdominal portions grayish, except the tip, which is brown. It takes from five to seven weeks to change from Fig. 49.— ArcT>T Chixch BCG, Blissua teucoptenc^. Say.

When winter comes the insects seek shelter under sticks, stones, leaves and rubbish of all sorts. This is one of the most destructive insects, especially as applied to wheat and oats, and also, though in a lesser degree, to corn. Mr. L.

Howard, now United States Entomologist, in 1887 estimated the losses from chinch bugs in nine States to be $60,000,000. Walsh, in 1864, estimated the loss in Illinois for that year caused by this bug to be $73,000,000, while Shimer claimed tliat during the same year three-fourths of the wheat and one-half of the corn of the Mississippi valley was destroyed by it, involving a loss of $100,000,000.1 * Abstracted from an article on the chinch bug in the second report of the New York State Entomologist for 1885. t Second report New York State Entomologist, 1885, p. 156. INSECTS. 137 Many different methods have been attempted to prevent the ravages of this insect, l)ut each one is more or less unsatisfactory. The area grown to wheat should l)e diminished. All trash about infested fields should be as fully l)urned as possible in fall, winter or spring. Insecticides may be used to advantage. Kerosene emulsion, diluted to about five per cent, is perhaps the most effective insecticide. To make the emulsion take one-half pound of common soap and dissolve in one gallon of hot water, after which add to the boiling mixture two gallons of kerosene and churn the mixture violently for about five minutes with a hand force pump. This may l3e diluted with water to make 30 gallons for use. This seems to be about the best of the insecticides for chinch bugs. For some years past experiments have been conducted to propagate among chinch bugs a fatal disease. A large amount of work has been done by Prof. F. H. Snow of Kansas Uni- versity in this direction. A peculiar fungi be- ing placed in contact with the bug soon causes its death. Healthy bugs may be inoculated with the disease and set at liberty in the in- fested fields and may spread the disease with such great rapidity as to practically annihilate the l)ugs. A perfect epidemic of the disease occurs. This fungus may be propagated and 188 INDIAN CORN CULTURE. distributed over the country, as done by Prof. Snow, and used to inoculate bugs where neces- sary. The work of Snow has been most en- couraging.* Clean cultivation is most essential in any case, and Forbes recommends heavy fertiliza- tion of lands as an additional safeguard.-}- Corn hill hugs ( SpJienophoriis). There are a number of forms of these bugs which are known as snout beetles or bill bugs. They are all medium-sized, dark-colored insects. With most FIG 51.— CoKN BILL BvG, Sphenophorus rubustus, Horn, a larva; 6, pupa; c, beetle, back view; d, beetle, side view. (After Riley.) species the adult insects sink the beak into the stem of the young corn plant and make small cavities in it into which the eggs are deposited, where they hatch later on. One of the most destructive corn-bill bugs is SpJienophonis och evens, Lee. Its depredations are mainly confined to recently reclaimed swamp lands.

The larva is white with brown head, the lat- ter small, body becoming very robust posteri- orly, so much so that it appears to be fully two-thirds as broad as long, and very much wrinkled. The feet are lacking. The adult is black beneath, but varying in color ahove from pale ochreous to plumbeous and cinereous. Length one-half to nearly three-fourths inch. The insect i^asses the winter in the adult form, and in spring feeds on the tender parts of stems of reeds and rushes, and later on on the same parts of the young corn. In late May or June the female burrow^s into the earth and deposits her eggs in or about the bulbous roots of a species of reed. The larvae burrow in these bull)s, which are often the size of a hen's egg and very hard, and transform to the adult in- sect therein, appearing on the rushes, reeds or corn in August or September. This species will probably never breed in the roots of corn. To get rid of this species the best method will be to drain the land thoroughly and get * Insect Life, Vol. II, p. 132. 140 INDIAN CORN CULTURE. rid of the plants it breeds in by l:)urning or cul- tivating them out. Fall plowing has been tried, but I am not informed witii what success. If the stubble is burned in spring some beetles of the other species may be destroyed.

The hind wings are of a paler shade, with a broad, blackish cater band enclosing a pale spot toward the apical portion. Conistock states that there are five broods of this insect in a season in the South, while in the latitude of Missouri, Southern Illinois and Virginia, Riley thinks there are but three. The adult insect deposits its eggs in the tip of the ear, among the silk. After hatching the larvae feed until about one-third grown, when they begin to tunnel through the kernels under the husks toward the butt of ear. In Tennessee the writer was unable to grow sweet corn suc- cessfully owing to the ravages of this pest. The grown worm is about one and one-fourth inch long, rather robust, tapering toward the head. In color the worms vary from pale green to dark brown. There are several black, shining, elevated tubercles on each segment, each bearing a short brown hair. The full-grown larvae make a round hole in the earth, the inside walls of which they cement over. At the bottom of these chambers these larvae change to pupae, where they pass the winter. It is recommended to plow in the fall, thus throwing up these chambers and subjecting the pupae to winter exposure and destroying 142 INDIAN CORN CULTURE. INSECTS. 143 them.

In four to seven days they will hatch, and the larva will then burrow into the kernel and begin to feed on the inside of it. In about three weeks it is full grown, when it is aljout one-fifth of an inch long. Then it burrows towards the outer end of the kernel, leaving only a thin cap to cover the cavity. A small white cocoon is then made in the burrow, and the larva in this soon changes to pupa, and after a short time emerges in the moth form. This insect is especially injurious in the South, where stored corn is often seriously damaged. North of Kentucky little inj ury may be ex^Dected from it, as it is a warm climate insect. At the New York State experiment station the w^riter had considerable experience wdth it, as it occurred in a collection of corn in the museum. These insects were brought to the museum in specimen ears shipped from the South and before their ravages could be stopped nearly the entire collection was ruined. In the field there is no known method of combating it. To destroy the insect in the seed, place the grain in a comparatively tight room and pour a little bisulphide of carbon in among the corn. This soon changes into a deadly gas and will destroy all insects inhaling it. But to save the seed the operation should INSECTS. 145 m jtri r^ -Str-" ■^- Xi 1 1(> repeated as soon as new moths appear. Tlie bisul- phide of carbon is very in- flammable, as Avell as jtoisonous, so great care should be taken not to ex- pose a fire to the fumes. Being heavier than air, the lunies will sink down through a pile of corn. The fumes of this gas would also destroy other insects injurious to stored grain, including the grain or barn weevil, and the grain Syl- van us. both of which are common in the South. Ac- cording to Weljster the worms are destroyed at a temperature of 120 deg. F., for four houi's, so if means can be obtained by which to heat the ears to this degree a very desir- able thing will be accom- l)lishcd. Other Insects.— W h i 1 e tiu'ic are numerous other insects which injure corn, thcv do it to so snniU an 10 146 INDIAN CORN CULTURE. extent that it is unnecessary to devote special attention to them. Grasshoppers, blister beetles, leaf hoppers, rose bugs, flea beetles, army worms, etc., all at times do slight damage to growing corn. Usually those insects which feed on the growing plant may be destroyed by spraying the leaves with some form of arsenic poison, such as paris green, london purple, etc. DISEASES. 147 CHAPTER XI DISEASES. The Indian corn plant is appreciably injured by but very few fungous or bacterial diseases — in fact less than is any other cereal. Of these smut is the only one commonly known all over the United States. The following diseases are the only ones of sufficient importance to especially merit atten- tion in these pages: Smut.— (Usfi I ((fjo i)iai/(h's, Corda.). Smut as seen l)y the farmer is either a distorted, green- ish-white piece of vegetable tissue, or a mass of black, greasy powder, which generally ap- pears breaking out fi'om an ear of corn or fi-oni the leaf or stalk when green or succulent. The source of this disease is a simple, tubular, minute plant, too small to be seen by the naked eye, which grows in the tissues of the corn plant and feeds upon its juice. These little plants, of which there are vast numbers, branch out in tubular form Avhon thoy find a spot in 148 INDIAX rORX CULTURE. the corn plant that i.s especially nourishing. Then, inside af these tubes, minute bodies termed spores (seeds) develop, and finally the spot becomes a mass of these, and then all of KiG. 56.— Corn Smttt breaking out on the ear.

A single culnc inch of them would contain over fifteen billions. The top of a pin- DISEASES. 149 head that has been muisteiied will bear from 30,000 to 50,000.* These spores are really seeds, and if the right degree of nioistnre is supplied they germinate in a few hours and produce very minute, thread- like plants, from which soon develop "sporids." The wind may blow these latter upon a young corn plant, in which case they may grow into its vegetable flesh and develop to a remarkable degree and eventually break out in the com- mon form of smut. This disease is distributed through the agency of the smut, and the more the spores are scat- tered about the more prevalent it may become. It is abundant all over the United States and in the corn-growing parts of Europe. While considerable damage may occur from this fun- gus the extent of this is not generally appreci- ated l)y corn growers. Bessey states i- that in Iowa he saw a piece of land the crop of which '^ fully 66 per cent had been destroyed." This, however, is an unusually severe case. Prof. W. H. Brewer says: J ''I have never seen a field which has been injured to the extent of one per * Bessey: Bulletin 11, Nebraska agricultural experiment station, Dec. 18, 1889, p. 29. t Bulletin 11, Nebraska agricultural experiment station.

Smut said to be injurious.— Smut is gener- ally thought by farmers to be injurious to live stock, yet but little satisfactory evidence is at hand to prove that such is the case, as it is com- monly eaten. But three experiments on this point have come to the writer s knowledge. Dr. Gamgee for three weeks fed two healthy cows on smut, wet and dry. The wet did no harm, but a loss in weight followed the eating of the dry. The animals had voracious appetites, were fed three times per day, and ate from 3 to 12 oz. at a dose. In three weeks they ate 42 lbs. of smut.* Prof. Henry of the Wisconsin experiment station performed a similar experi- ment on two cows.f One cow ate as much as 32 oz. of smut in a day, and the other up to 64 oz. The latter cow died suddenly the next day after eating a large amount of smut. Prof. Henry attributes her death to having eaten this, which is not strange. In making a post- moyteni examination no serious derangement was found in the intestines, but Prof. Henry thinks the brain was affected. An associated press dispatch in the daily papers of Nov. 10, *Report Comraissioner of Agriculture on Diseases of Cat- tle in the United States, Washington, 1871, pp. 73-76. t Breeder's Gazette, Oct. 10, 1894. DISEASES. 151 1894, comments on the sudden death of cattle in Illinois and sa3's that farmers attribute it to the stock eating smutted corn. Prof. ]\rorrow, so the dispatch says, thinks not, as they had fed a steer two bushels of smut at the Univer- sity of Illinois and it had not injured him. It is very questionable if cattle are injured by smut in the fodder; yet it will be safer and better to keep it out of the rations. Preventing smut. — There is no absolutely sure method of preventing the appearance of smut. The spores on seed corn may be de- stroyed by the use of sulphate of copper (blue vitriol or bluestone). A strong solution in water should be made, nsing about half a pound of the sulphate to a gallon of water. The seed may be soaked about half au hour, after which it should be removed from the liquid and dried. The smut may also be killed by soaking the seed in water at 160 deg. F. for five minutes. It is also important to adopt preventive meas- m'es. The spores will pass through animals in the manure and germinate, so that is a reason why stock should not eat it. The smut in the field which can be secured should be burned. Kotation of crops will also reduce the degree of prevalence. Bacterial disease.— This is a disease caused by a very minute class of plants termed bac- 152 INDIAN CORN CULTURE. teria, so small that they can be seen only under powerful microscopes. One of these plants consists of a single cell, with an outer coat, and inside contents. These plants in- crease by dividing in halves or sections and each developing into a perfect plant, or by spores which they may produce. Bacteria can withstand great extremes of heat and cold. There are many different kinds, one of which causes injury to Indian corn by develof)ing in its tissues and juices. Symptoms.— The disease is characterized by the plants turning yellow and sickly while young. The roots of the plants, especially the lowest ones, decay. While the whole plant will be affected, the injury is most apparent in the lower part of the stem, which will be dis- colored and perhaps dying. Sometimes the stem appears corroded, and semi-transparent, firm, gelatinous material gathers upon these marred places. After midsummer the leaf sheaths become discolored and spotted, with an appearance of decay. If these sheaths are stripped off the injury is made more conspicu- ous. These injured or spotted places appear watery and sometimes are smeared more or less with a thin coating of the gelatinous matter. Finally the ears are attacked, the husks wilt, turn brow^n and become packed close together, and gummy matter exudes from the tissues. DISEASES. 153 Often a white fungus occurs and permeates the entire ear. This disease was first investigated in 1882, and most of the information known of its char- acter is derived from studies made of it by Prof. T. J. Burrill of the Illinois experiment station.* The malady is widely prevalent, with- out doubt, yet is mainly known in Illinois and Nebraska. It is thought that animals eating cornstalks affected by this bacteria will die of what is called "cornstalk disease.'' While this trouble is not confined to spociul kinds of soils and conditions it has been found most prevalent on rich land. Thus far the writer knows of no method proposed to prevent the occurrence of this disease. Rust occurs on Indian corn, but only to a slight extent and at uncertain periods. The loss from this disease is probably very imma- terial. * See Bulletin (5 of that station, August, 1889, pp. 165-175. 154 INDIAN CORN CULTURE. CHAPTER XII. CHEMICAL COMPOSITION AXD DIGESTI- BILITY.

Value of the corn crop. — The great value of the corn crop to America is clearly brought out in these tables. No other plant we grow will produce 3.172 lbs. of digestible food on one acre of land at so little expense. No other cereal crop yields the farmer so large a return for his labor as the Indian corn. It is the king of the cereals. THE FEEDING OK LIVE STOCK. IGi CHAPTER XIII. THE FEEDIXCI OF LIVE STOCK. No one kind of food, unless we except milk, meets all the requirements of the domesticated animal. The composition of all others is one- sided, and it is essential that two or more foods he fed so as to give a ration that will be fairly balanced, and not one-sided. Some foods are more nearly perfect for certain animals than others, but combinations usually l)ring about the best results in feeding. Constituents of foods.— The chemist who an- alyzes a food finds it composed of several groups of sul)stances quite different in character. For the feeder's purpose three of these only need be considered. First is the i^rotein, consisting of a class of bodies best represented in the com- position of the white of an egg or in perfectly lean meat. The muscles of the body consist mainly of protein. Another group is known as nu-hoJii/drafrs, or heat-formers. These consist mostly of starch, sugar, and woody fibre or cel- lulose. The third group is the faf of the plant, as for example the oil extracted from the cot- 11 162 INDIAN CORN CULTURE. ton seed. Those foods which contain a large per cent of carbohydrates and fat are usually termed carbonaceous. Nutritive ratio.— Foods contain these three groups in different proportions. W hat we know as a rich feeding stuff, as oil-meal^ for example, contains a much larger percentage of protein than is possessed by the average food. An an- imal cannot eat so much of it as wliere it is specially abundant in carbohydrates, and not in protein. The relationship existing between the protein on one side and the carbohydrates and fat on the other, is termed the nutritive ratio, meaning one part protein to so many of the other two combined. Where the ratio of a food is 1 :2 it may be termed a narrow nu- tritive ratio, while if it is 1 :12 it is a wide one. A food having a ratio of 1:6 would be well bal- anced^ j)erhaps, but if it was an extreme on either side of this it might be ill balanced. Feeding standards.— Many feeding experi- ments, made both in Europe and the United States, have shown that animals require prac- tically certain amounts of each one of these classes of foods to maintain the body or to pro- duce growth. Wolff, a German, after much experimentation, published a table of feeding standards. This table gives the number of pounds of dry matter (food without moisture), protein, carbohydrates, and fat required by the THE FEEDING OF LIVE STOCK. WS animal per day, per head or per 1.000 lbs., ac- cording to circumstances. In connection with these tables Wolff published another tal)le showing how much of the protein, carbohy- drates, and fat were digesti))le in the different foods available. A similar table has been pul)- lished by Allen showing the digestibility of American feeding stuff's."'' Wolff's feeding standards are given in the following tables: PER DAY AND PER 1,000 LBS.

For example, Wolff gives for a milk cow weighing 1,000 lbs. a ration containing 24 lbs. dry matter, 2.5 lbs. protein, 12.5 lbs. carbohydrates and 0.4 lbs. fat. After examining into numerous rations fed by prominent dairymen the Wisconsin, New York and Connecticut experiment stations have found the al»ove amounts recommended by THE FEEDING OF LIVE STOCK. 165 Wolff to be substantially near those fed by these dairymen. The feeder, however, has to keep in mind that he is dealing willi individual aninuils Avith different appetites and digestive capacities, so that rather than attempt to feed each by rule he should hardly expect the feed- ing tables to more than assist him in judiciously selecting and comlnning the foods and suggest- ing the extent to which they may be fed.

It has long been known that the grain of Indian corn is a most valuable food for domes- tic animals. It is generally relished by farm animals and imparts a quality to meat, milk or butter which ranks it among the most, if not ihe most, important common feeding-stuffs at our command. During recent years it has been well established, also, that the mature plant, independent of the seed, has a high food value, either green or as dry fodder. Rations illustrated — Without attempting any elaborate discussion of the merits of Indian corn as a food, and presenting a large number of feeding rations, the balance of this chapter will be devoted to a few illustrations of rations and to demonstrating its importance when fed on the farm under certain conditions. Man}' different combinations of foods might be dis- cussed, with corn as a part of each ration, but the space to be occupied here will not admit of this. The purpose is rather to note the desir- able and undesirable use of corn as a food in common practice, so that a brief amount of space will l)e devoted to corn as a food for each class of farm animals. Horses. — In that part of the country where corn forms a prominent grain crop, as in the Central AYest, and in much of the Southern THE FEEDING OF LIVE STOCK. 107 States, the priiicipal grain fed liurses is c lbs. hay. 5 lbs. bran, 2 lbs. cotton- seed meal, 3 lbs. corn-meal. (4) 50 lbs. corn silage, 9 lbs. clover hay. (.■)) 32^ lbs. corn silage, 6 lbs. clover hay, 3 lbs. corn-fodder, 5 lbs. corn-meal, 4 lbs. shipstuft", 2 lbs. oil-meal. (6) 24 lbs. corn-fodder, 5 lbs. corn-meal, 3* lbs. bran, H lbs. oil-meal, i lb. cotton-seed meal. The above rations are not given as perfect ones, but as representing some of those fed by prominent dairymen of the country. The late Prof. E. W. Stewart gave much attention to feeding problems. The five fol- lowing rations were recommended by him for the purposes specified:'" For fattening cattle, 1,000 lbs. weight: 20 lbs. corn-fodder. 6 lbs. corn-meal. 6 lbs. linseed cake. * Bulletin No. 38, Wisconsin agricultural experiment sta- tion, p. 44. 172 INDIAN CORN CULTURE. For dairy cattle, 1,000 lbs. weight: (1) 10 lbs. corn-fodder, 10 lbs. oat straw, 2 lbs. linseed-meal, 4 lbs. malt sprouts, 10 lbs. oat and corn-meal. (2) 60 lbs. corn silage, 5 lbs. hay. 2 lbs. linseed-meal. 4 lbs. bran. (.3) 18 lbs. corn-fodder, S lbs. wheat bran, 4 lbs. cotton-seed meal, 4 lbs. corn-meal. (4) 17 lbs. clover hay, 3 lbs. wheat bran, 10 lbs. corn-meal. The writer has fed very young calves skim- milk in which was stirred 2 to 4 oz. of very fine corn- meal per feed, with satisfactory results. Numerous old feeders drop a handful of shelled corn in the milk bucket when feeding calves, and they soon learn to clean up the grain with avidity. Sheep. — In the West, shelled corn is more often fed to sheep than any other kind of grain, a pint a day in a general way being given ma- ture animals, although many feed much heav^ier in finishing for the market. It is an interest- ing fact that while if mature cattle are fed shelled corn some of it will pass through them whole, sheep will digest the kernel entirely. Feeding experiments on sheep have been un- dertaken at the Michigan station by Smith and Mumford to an extensive degree.* During the winter of 1893-94 125 lambs were divided in nine lots and fed different rations for fattening. In all of these rations but one corn was fed, as * Bulletin 113, Michigan agricultural experiment station, October, 1894 THE FEEDING OP LIVE STOCK. 178 is shown in the following table, which gives a snnimary of the resnlts of the expei'iment.

The other feeds were somewhat more expensive. At the Wisconsin station a ration of shelled corn, silage, and cut corn-fodder, fed fattening wethers, yielded the cheapest gain. One hun- dred pounds of gain cost $3.46 in 1890 at this station when fed this ration. In 1891 the same kind of ration made 100 lbs. of gain cost $3.70. This ration was 1.3 lbs. corn-fodder, 0.8 lb. corn silage, and 1.8 lbs. shelled corn per day and head. A ration of corn and oats, equal parts by weight, clover silage and clover hay, made the cost of 100 lbs. of gain $4.01. A ration of oil-meal and oats, clover silage and clover hay, made 100 lbs. gain cost $6.09. The wethers receiving the clover and oats and oil-meal produced more wool than 174 INDIAN CORN CULTURE. the corn-fed ones, but this increased weight was chiefly due to increase in yolk. Pregnant ewes should not be fed a fattening food like corn. In fact corn is essentially a fattening food for sheep. If this end is not de- sired, then oats, bran, and oil-meal may be fed to better advantage, along with roots or silage. Writing some years ago* Mr. F. D. Curtis, then a well known student of sheep husbandry, said : "No argument can now convince me that corn is a good kind of grain to give sheep to make them grow well or fit them for the lambing season. A very little corn will do mixed with other grain. * * * Corn makes the sheep fevery, and this dries the wool, makes it brittle and checks its growth. It inflames the udders of the ewes and makes a big show of milk, whereas it is actually mere fever, inflam- mation and swelling. It makes the lambs weak and tends to cause the ewes to forsake them, or not to own them." It is well to hear both sides of this question, but it is practically true that the grain of corn should not be fed pregnant animals of any class, sheep as well as others, especially to- ward parturition. Bran or oats are much bet- ter at this time. But for promoting the laying on of flesh corn is a superior feed. Corn-fodder and silage have not as a rule been largely fed sheep, but their use is becom- ing more and more common. Either one of these coarse foods may be fed sheep with sig- * Country Gentleman, Jan. 29, 1885. THE FEEDING OB' LIVE 8T0CK. 175 nai success. Mr, A. 0. Fox, one of the most extensive owners of Shropshire sheep in Amer- ica, writing of feeding shredded fodder, says in a recLMit letter:* "When I first put the ewes into winter quarters upon the dry fodder I feared they would not relish it, but I soon found they took to it even more kindly than to good hay. They ate it ravenously and would fill themselves to perfect satisfaction and lie down in contentment to sleep. I am now thoroughly convinced that they have done better upon the corn-fodder ration than they would have done upon good, bright mixed clover and timothy hay. The corn-fodder did not have the slightest constipating eflFect. I have fed the lightest grain rations this winter that I ever gave my ewes and they are in fine bloom. Their fleeces ar-e much cleaner than if they had been fed hay. and as for lambing, we are now well into the most successful lambing season we ever experienced; 98 ewes have to-day 158 lambs, which you will see is 160 per cent. Every lamb is strong and hearty from birth. The ewes are experiencing no trouble with their udders, and in fact I do not see any objection to confining them exclusively to corn- fodder instead of hay." At the Wisconsin station corn silage has been fed wether lambs and suckling ewes with most satisfactory results. In the 1893 report of the station Prof. Craig says, where fed wethers, "the corn silage, considering its action as a food and the fact that it can be preserved cheaper and better than the clover silage, was the most satisfactory." Further, in referring to this food for breeding ewes, he says: "Of the succulent fodders, the best re- *Breedii's Gazetk, March 13, 1895. 176 INDIAN CORN CULTURE. suits were secured from feediug corn silage. It is cheap, the ewes like it, and they can easily be kept in a healthy condition when it forms part of the ration. The only danger lies in the fact that it may contain too much corn for breeding ewes." At the Michigan and Cornell University stations silage has also been fed with success. There is plenty of good evi- dence in the agricultural press of the past ten years demonstrating that corn silage is a valuable succulent food for sheep. Swine.— Being the cheapest food available to the corn-grower in the West, most of the hogs shipped into the market have been raised and fattened on corn as the only grain food. In the past, however, pigs have been fed corn too ex- clusively. Numerous experiments have shown that better results are secured where some other grain is fed, using corn, however, as the principal food. Prof. Henry at the Wisconsin experiment station has probal>ly conducted the most extensive feeding experiments on swine extant. His work emphasizes the importance of using other foods in connection with corn. Brood sows should be fed lightly of this and mainly with bran, shorts or some such food, be- fore and at farrowing time, to get the best results. Pigs fed corn exclusively lack the strength of bone and desirable meat quality that is j)0ssessed l)y those that receive in con- THE FEEDING OF LIVE STOCK. 177 nec'tioii with the corn some food rich in pi'o- teiii and ash. The following table, from the eleventh annual report of the Wisconsin sta- tion, contains in concise shape much valuable information bearing on the question of amount of food required to produce 100 lbs. of pork. It is to be noted here that corn is the important "Train factor in these rations: KIXD OP FOOD.

The first ration also has the advantage of being much the cheapest of the three. The practice obtains to a large extent of feed- ing steers corn on the ear and letting pigs fol- low after and feed on the grain which passes through the steers undigested. AV^here steers are thus fed this is unquestionably the most 178 INDIAN CORN CULTURE. economical practice. At the Wisconsin station a bnshel of shelled corn made 11.4 lbs. of pork when fed alone to pigs, while a bushel fed to them when running with corn-fed steers made, with the help of the droppings of the steers, 17.6 lbs., or over one-half more. Corn -and -cob meal vs. corn -meal. —The question is often asked as to which is the more valuable food, corn and cob ground together or corn-meal alone. Considerable experimental feeding has been conducted to throw light on this question, and very generally the informa- tion secured favors the grinding of the corn and cob together. It is assumed that the pure meal packs in the digestive organs and is not so readily permeated by the digestive fluids as is the corn-and-cob meal, the cob making the mass more porous. At the Maine experiment station Jordan fed two lots of pigs 81 days^ one receiving corn- and-cob meal, the other pure meal. There was but little difference in the gain made by each lot. Shelton at the Kansas station found that it required 650 lbs. of corn-and-cob meal to make 100 lbs. of gain when fed to pigs, while it required 670 lbs. of pure meal to make an equal gain. In a steer-feeding experi ment Prof. Shel- ton also secured results favorable to the use of the cob with the corn. General testimony seems to show that a THE FEEDING OF LIVE STOCK. 179 pound of cuni-iind-colj nieul has the Sciiiie feed- ing value as a pound of pure corn-meal. In this connection it is important to grind the cob finely. The wi-iter has had difficulty in successfully feeding corn-and-col) meal to pigs when the cob was flaky or coarse, as they re- fused to eat it unless well milled. The by-products of the corn plant eml)race most important and valua))le feeding-stuffs. The glucose and starch factories, distilleries and hominy mills produce liy-products from the corn grain that are used for stock food on an extensive scale. They include gluten meal, gluten flour, gluten feed, glucose meal^ glucose feed, maize or starch feed, sugar feed or meal and grano-gluten. These are produced by dif- ferent methods of manufacture and so vary widely in composition. Quoting from Allen:* The corn is soaked until it is swollen and soft, and is passed through the mill while wet, the hulls and germs of the corn being rubbed off. In some cases the starch is separate• 1890 173,8:56 5,52;i.611 1891 5,7o9 246,393 1890 99.4C0 2,448,625 1891 10,357 592,178 of that grown is produced in the United States, while the large share of the balance is grown in a few countries along the lower Danube river in Europe, in Spain, Argentine Republic and Mexico.

A number of subjects of interest and impor- tance are placed in this chapter. They seemed inappropriate to the subject matter of the pre- ceding chapters, yet of sufficient importance to be classed by themselves under this general heading. Detasseling.— Since 1SS8 this subject has re- ceived considerable attention at some of the experiment stations. According to ;MeLaren'- in 1739 James Logan of Philadelphia pul)lished an account of some experiments made by him where he removed the tassels of the corn plant and transposed the pollen. In 1879 Beal called attention to the fact that a corn plant does not naturally fertilize itself, the pollen being dis- charged from the tassels before the appearance of the silk.t Among the early experiments made at the stations some evidence seemed to indicate that * Agricultural Science, Vol. 7, p. 319. t Michigan Board of Agriculture Reports, 1S79, p. 198; 1880, p. 283. 214 INDIAN CORN CULTURE. a larger crop was secured bj^ detasseliiig. Later investigations, however, in most cases gave evidence of reduced crop yield due to this practice. In 1888 Shelton of Kansas found a loss of nearly 10 per cent due to detasseling.* Roberts in 1890, at Cornell Universit}"^ how- ever, secured a gain of 50 per cent due to de- tasseling, and this experiment attracted wide attention to the subject.f Further work at Cornell seemed to corroborate this result in a measure. In 1892 there was a gain in weight of good ears amounting to 15 per cent, and of poor ears of 26 per cent on the detasseled rows, besides being a gain in number of ears.:{; At the Illinois station, however, several years of experimentation have shown no advantage to be derived from this process, but if anything a loss. At the Nebraska station, a decided loss is shown from detasseling.§ Ten detasseled rows 20 rods long each gave a jield of 528 lbs. of corn; 10 alternate rows, not detasseled, 1,220 lbs., and 20 undisturbed rows elsewhere in the field, 2.369 lbs. The cost of detasseling was estimated at $1.25 per acre. At the Kansas station in 1891 the results were adverse to detas- * Kansas experiment station.
