Since the introclnction of sugar cane into the United States over a hundred j'ears ago its cultivation for the purpose of manufacturing table sirups has been extended until it is now practiced over large areas of southern Texas, nearly the whole of the Slate of Louisiana, poi-tions of southern Mississippi and Alabama, the southern part of Georgia and South Carolina, and over the whole extent of Florida. Nearly all of the methods which have been emijloyed for this pur- pose have been of a crude nature and involve no accurate knowledge of the character of the cane employed, the amount of sugar which it contained, or the chemical composition of the product secured. Very few manufacturers have measuicd the land on which the cane was grown, weighed the cane pi-oduced, or determined tlie percentage of extraction in the mills employed or the yield per ton and acre of the sirup secured. The quality of the product made has usually been of high character, and the appreciation of its value for the breakfast tabhMind for cook- ing pui-poses has gradually grown until it is now a recognized food product throughout the whole of the region mentioned and in many other parts of the Union to which it has l)een sent. So great has become the demand for this wholesome, palatable, and nutritious article of diet that in the past few years manufacturing establish- ments have been erected on a much more elaborate scale and under much more rigid control than heretofore. The old-fashioned mule mill and iron kettle have given way to the steam mill and steam evaporator. Imijroved methods of the treatment of the juice have been practiced, and attempts have been made to secure an article of standard quality and properties. Merchants desire to handle a uni- form grade of sirup, so that when its value is once established thej^ can meet the demands of their customers for this particular kind. One of the greatest difficulties, from a cominercuil point of view, with which the table sirup industry in the South has to contend is this lack of uniformity. This, coupled with the tendency of the sirup to ferment in warm weather, has i-estricled its markets to a rather limited area. An additional difficulty which these sirups find on the 5 6 MANUFACTURE OF TABLE SIRUPS FROM SUCIAR CANE. market is the fact that our grocery stores are stocked with artificial sirups; that is, those made of mixtures of various kinds in Avhich glu- cose is one of the essential ingredients. There should, be no restric- tion of the legitimate trade in mixed articles of wholesome food, but when they are sold under names which are misleading, an injury of a serious character is done to products which are truly representative in name and character. There can be no valid objection to the sale of mixed table sirups of any kind, provided they contain no injui'ious ingi-edient, but theii- sale as maple, sugar-cane, or sorghum sirup manifestly works an injury to a legitimate trade in the genuine articles. Cliiefly tlirough the representations of Capt. D. G. I*urse, president of the Savannah Board of Trade, the U. S. Department of Agriculture has become intere.sted. in tlie develoimient of the table-sirup industry in the Soutli. In Noveml)er, 1901, the wi-iter made a visit to some of the principal centers of this industry to study the conditions existing and to confer with manufacturers in regard to the im^jrovements and tlie investigations which the Department of Agriculture might undertake to the advantage not only of tlie pi-oducers but of the consumers of this important product as well. Starting from Savannah on Novem- ber 18, visits were made to various points on the Central Railroad of Georgia. Tlie morning was cold and frosty, and the cane Avhich had been exposed was found frozen. Icicles Avere noticed in many localities. The excursion was conducted by the land and industrial agent of the Georgia Central Railroad. 'J'he first visit was made to the steam factory of Mr. J. G. Wells, of Guj^ton, which was found well equipped and conveniently arranged for economy in handling thc^ raw material and the finished product. The character of the cane grown by Mr. Wells is shown in PI. I, fig. 1, representing one of tlie fields near the factory. The arrangement of the ev^aporating apjiaratus, which was a self-skimmer, is shown in PI. I, fig. 2. The ingenious arrangement of this skimming appliance secured a very pure and bright finished article, and at the same time the scums were i-emoved without an^^ notable loss of sirup. A general view of the factory, from which can be seen the neatness and strength of the structure, is shown in PL II, fig. 1. The next locality visited was the factory of Mr. E. E. Foy, at Egypt. A general view of Mr. Foy's factory is given in 1*1. II, fig. 2. Mr. Foy makes a specialty of feeding the skimmings and other waste j)roducts to pigs. The arrangement of his pigpens is shown in PI. Ill, fig. 1. The well-known fattening properties of skimmings was illustrated in a striking manner l)y the sleek and rot und condi- tion of the pigs being fed. The next factory visited was that of Capt. Thomas J. James, of Adrian. Captain James had one of the most extensive cane fields CANE FIELDS AND SIRUP FACTOEIES. seen in Sontliern Georgia. A striking illustration of the luxuriant growth of the cane is given in PI. Ill, fig. 2. Captain James has a large factory operated by steam. In addition to the cane fields the plantation of Mr. J. W. Olliff, at Statesboro, was also inspected. At the time of the inspection of this region the sirup canii)aign was not completed in many localities, and largequantitiesof cane were still in the fields. An interesting question was raised at once in regard to the effect of the severe cold then pre- vailing on the cane itself. In most places tlie cane is either windrowed or cut and piled in bulk and protected by the leaves and tojis. In these instances the cane w^as not frozen, and there was no question in regard to its preservation until the end of the manufacturing season. The cutting of the cane in this way is not injurious to the i^roduct, as would be the case if sugar making were practiced, since one difficulty whicli attends the siruiJ industry in Georgia is the tendency of the finished product to crystallize and thus decrease its value on the market. Keeping the cane windrowed or in heaps for some time after cutting will afford the opportunity for the inversion of a part of the cane sugar, thus diminishing the tendency to crystallization in the linished product without diminishing the amount of the product oi- impairing its quality. On the 19th of November an inspection of the caius lields and fac- tories in the southern part of Georgia, near the Florida line, w-as accom- plished. In addition to Captain Purse, the x>art3^ included Mr. James Menzies, general freight agent of the Plant System, Mr. C. B. Rob- erts, and Mr. D. F. Kirkland, superintendent of the third division of the Plant System. At Waycross the train was met by Mr. W. AV. Sharpe, Mr. G. R. Youmans, and Mr. J. W. Greer, who urged that a visit be made to the cane fields near that cit}', but the itinerary already arranged would not allow a stop-over at that time. At Valdosta the inspecting party was welcomed by Mr. J. G. Craw- ford; Mr. J. M. Wilkinson, president of the Valdosta Southern Rail- road; Mr. Brantley, editor of the Valdosta Times; Mr. Will McRee, Mr. William Roberts, Col. Ben Jones, and other citizens. At Kindcrlou an inspection w^as made of the farm and factory of Mr. McRee. Here some of the best illustrations of the intensive culture of sugar cane were found. An excelh^nt idea of the luxuriant char- acter of the cane grown at Kinderlou is shown in PI. IV, figs. 1 and 2. A most interesting incident of the visit to Kinderlou was an inspec- tion of one of the cassava fields on the plantation. The growth of the cassava was of the most luxuriant kind, and although the leaves had been frosted, it still presented a most attractive appearance, as is shown in PI. V, fig. 1. The purple variety of cane was the one chiefly grown on ]Mr, McRee's plantation. Some of the cut stalks alread}' in the mill measured over 8 feet in length and AVi^ighed from 4 to G pounds. 8 MANUFACTURE OF TABLE SIRUPS FROM SUGAR CANE. Althong'h no weighings were made of measured portions, it was evi- dent to all familiar with cane fields and the yields which they give that the field of cane showii in PI. IV, fig. 1, would yield from 25 to 30 tons per acre. Mr. McRee estimated that his crop would yield an average of 850 gallons of sirup per acre. lie had 5G acres in cane, all of which was devoted to siruj) making. The fertilizer which he used was a complete one, composed of potash, cotton-seed meal, and acid phosphate, and of this mixture the amount usually applied is from SOd to 1,000 pounds to the acre. On new land, however, the quantity of this material is corresjiondingly diminished. This part of Georgia appears to be practically the center of the cane-sirup industry, and, judging by what has been accomplished by Mr. McRee, there is no limit to the extent of the industry save the capacity of the market to be supplied. The Georgia Land and Improvement Company is said to have options on over 400,000 acres of land in Clinch C/Ounty, which will be utilized for the establishment of a cattle industr}^ and for raising cane. At Quitman the party was taken in charge by Judge Joseph Till- man and Mr. W. A. Davis. The board of trade was visited and a large number of the citizens of Quitman were presented to the pai'ty. W. A. Davis & Co., of Quitman, sell about 3,500 barrels of sirup a 3^ear. Until a few years ago the market was restricted to Georgia, but it now extends from Massachusetts to Texas. From Quitman the party i^roceeded to C-airo, where the mill of Mrs. M. L. Wight was visited. This is th(^ largest sirup mill in this sec- tion and is a type of tlie best modern construction. In most of the factories visited no attempt was made to (chemically clarify the juices, but dependence was placed altogether on the action of heat and skim- ming. At the Wight mill, however, the juices were sulphured cold, as is practiced with the cane juices used for sugar making in Louisi- ana, and subse(j[uently lime was added nearly to neutrality, thus pro- ducing a good clarification without darkening the color of the finished product. Cairo is the center of shipment for sirup iu southern Georgia. About 2,500 acres are planted in cane within a radius of 15 miles from the town, and the shipment from Cairo last year amounted to 10,000 barrels of sirup. A general view of the Wight mill is shown in PI. V, fig. 2. Particular attention is called to the contrivance at the Wight mill, as shown in the figure, for handling the cane by machinerj'. In load- ing a wagon ropes are first laid across the wagon body, on which the canes are laid. These ropes are afterwards tied, and by means of a crane the whole load is removed at once. The factory is built on the side of a hill, so that all the handliug of the nuxtei-ials iu the factorj% after the unloading of the cane b}" nunins of tht; crane, is by gravity, thus securing the greatest economy iu manual labor.

A synopsis of the address is as follows : CANE AND CASSAVA CULTURE IN FLORIDA. ByH. W. Wir.KY. The problems connected with the sngar und starch ])ro(hicts are four or five in nnniher. First of all. the soil is to be considered, and therefore agricnltnral interests should pay some attention to staple crops — that is, crops that have a market the year round, and can he preserved and marketed at any time. Sugar and starch are types of such crops. These substun(tes take absolutely nothing from the soil; they are fabricated by the plant from the atmosphere and water; hence the sale of such products does not tend to impoverish the soil. The soils of Florida are largely of a sandy nature — that is, they have been deposited from water; they are typically different from the soils of the great Northwest, wliich were produced by the grinding effect of moving icebergs, and represent the richest soils, probably, in the world. Sandy soils are not suitable for prodiTcing wheat, for instance, but they are well adapted to producing sugar and starch. In Florida it is more a question of climate than of soil, since, with a favorable climate, scientific agriciilture will produce a crop from almost any kind of soil. The second problem to be considered is that of fertilizers. Perhaps there is no State more favorably situated than Florida in respect to fertilizers. You have here inexhaustible deposits of phosphate. In the leguminous crops which grow here, namely, peas, beans, alfalfa, and beggar-weed grass, you have a most valua- ble means of assimilating nitrogen from the air. In cotton seed, fish scrap, and other animal refuse you have access to large stores of nitrogen. Through your seaports stores of fertilizing materials, snch as nitrate of soda and potash salts. can be brought from Soiith America and Germany. It would be hard to find any other portion of our country where fertilizers could be sold more cheaply than in this State. CHAEACTER OP THE MARKET. The third problem is the character of the market. This country is the greatest sugar and starch consumer in the world. We use more than 2,000,000 tons of sugar annually. Of this quantity, before the Spanish war. we made only about 300,000 tons — about one-seventh of all. Since the Spanish war we have acqiiired Hawaii, Porto Rico, and the Philip- pines, all of which give iis large additional (paantities of sugar. This year we will produce about 100,000 tons of beet siigar, so that at the present time it may be said that we produce about one-third of all the sugar we consume; but still there is a vast foreign market which we might supply with the home prodiict. There is no danger, therefore, of overstocking our home market with increased sugar production, nor is there danger of the beet sugar driving the cane sugar out of the market. For many purposes, as, for instance, the manufacture of sinip, beet sugar is unsuitable, and there will always be a demand for all the cane sugar that can be made. The sugar crop of the whole world for the present year is about 10,000,000 tons, of which nearly 7,000,000 are made from the sugar beet. 10 MANUFACTURE OF TABLE SIKUPS FROM SUGAR CANE. THE SUGAR BEET. The sugar beet can not, however, be grown in Florida profitably. Here you must depend f)n the svigar cane for sngar and upon the cassava and potato for starch. From starch ghicose can also be made, and it seems to me that in the near fiTtnre the glncr)se industry will pass from the indian-corn belt to the cassava and potato belt. In one particular industry Florida and the southern parts of Georgia and Alabama stand i)reeminent. and that is the manufacture of table sirup from sugar cane. It is important, however, to secure uniform grades to hold the markets of the world, and this can only be accomplished by mixing together the products of small farmers or by the establishment of central factories, where the cane grown in the neighborhood can be manxifactured under standard condi- tions. By the development of these great industries, sugar and starch making, includ- ing table sirups, xmtold wealth will in the near future flow into Florida. From, by-products of the factories immense quantities of cattle food can be obtained, both from sugar cane and the stai'ch-producing plants. Thus a dairy indiistry can be established in connection with sugar and starch making, which will add much to the wealth of the State. From Jacksonville the party returned to Brunswick, Ga., where a banquet was given by the board of trade at tlie Ogletliorpe Hotel, after wliieh a reception was tendered at tlie Pluenix C-lul). Tlie ques- tion of the development of the sugar-cane and cassava industries was informally discussed at this reception by the leading business men of Brunswick. From IJi'unswick the party proceeded to Waycross, where it was met by the board of trade of that city and where samples of canes, gathered from different parts of the locality, were inspected. The magnitude of these canes is best shown by the photograph taken at Waycross, showing a number of gentlemen most intcn-ested in tlie industry and the size of the canes typical of the gi-owth secured in the immediate locality. (PI. VI, fig. 1.) At Waycross one of the l)est of the small mills for making sirup was insi)ected, viz, the mill of Mr. Hatcher, about 1 mile southwest of the town. This mill is a small one, operated with a single mule as power, and is best illustrated b}' referring to PI. VI, fig. 2. The method of feeding th<^ cane to this mill is shown in PL VII, figs. 1 and L*. The evaporator, which is a single iron kettle set in masonry, is shown in V\. VIII, fig. 1. The structure of the furnace at Mr. Hatcher's mill, whi(;h is the best type of this character of furnace, is seen in PL VIII, fig. 2. One of the most interesting places visited near Cairo was the tlioroughly primitive establishment of Capt. E. A. A^'anhmdingham. It was already growing dark on our arrival, and thus an oppoi-tunity t was alforded of seeing this (juaint factory in its most picturesque I state, viz, illuminated by a tor(;h of "lightwood." This method of ! illumination is the one llni^•ersally practiced in the old-fashioned I establishment represented in PL IX. THE SOIL. 11 It must be admitted tluit some of the ])est sirup which has been brought to our attention lias been manufactured in the simple way illustrated in the figure. Of course, the quantities that can be made in a single kettle are limited, and there can be but little commercial im- portance attached to goods manufactured in this waj'. For the sup- ply of the faj-mer himself and his neighbors, ho\ve\'er, it is more than likely that this method of manufacture will continue to exist for a long Avhilc, and, in fact, there seems to be no necessity or desire that it sliould ever entirely pass away. A similar establishment is also represented in PI. X, which is also interesting in being the property of a colored man, William Loinax, living near Cairo, Ga. The scene is thoroughly characteristic, and represents at its best the rural life of this region when the s<>as()n for siru]) making is at its height. THE SOIL. Geologically the soils in southeastern South Carolina on which sugar cane is grown lie principally on the formations known as Lafay- ette and Marine Pliocene and Miocene. Agricultui-ally they are classed as sand soils, and the natural timber growth originally found on them was almost exclusively longleaf pine. Tliese soils, as is well known, have a low fertility and r(M[uire genei'ous fcrlili/.ation to pro- duce paying ci'Ops. The same soils prevail in southern and southwestern Georgia, while in Florida, without any pronounced difference in the ai)pearance of the soils, the geological formations are chiefly Marine Miocene in the nortliern part of the iir^ninsula and Marine Pliocene in the southei-n and interior central regions. The Lafayette formation is composed of distinctive orange-colored sands and clays, sometimes interbedded w ilh gi-avel or intei-spersed with [)ebbles. The formation is overlaid by the alluvions of small streams, by aH)lian sands, and in some places by wave- washed debi-is. The overlaj^ is also often ccmiposed of the characteristic clays, sands, and gravels of the Columbia formation, especially in proximitj' to large streams. This area has also been described by the nanu's "orange sand," "drift," "([uaternary," and "southern drift." The Lafaja^tte formation in Georgia is ovei-laid loi- thousands of squai-e miles with the sands of the Cobnubia fornuition, covered origi- nally, and still to a great extent, with longleaf pines. A typical soil on the Suwanee River, between Hamilton and Columbia counties, was found to have the following formation : Feet. 1. Gray soil, sand, and humus 3 2. White sand . 4 3. Clay with silicified corals and oyster shells 6 to 8 4. Indurated clayey rock ... 2 12 MANUFACTUEE OF TABLE SIRUPS FROM SUGAR CANE. Throughout large areas in Florida and, to a less extent, in Georgia and South Carolina, in low, swampy localities, the soil has become overlaid with vegetable deposits of a humus nature. These vege- table soils are deficient in mineral jjlant foods, but become very fertile when properly drained and fertilized. For a more detailed geological account of the soils of the localities referred to, liulletin No. 83 of the U. S. Geological Survey may be consulted. A valuable contril)ution to the study of the soil of Georgia is also found in the Tenth Census liei^ort, vol. 0, on the cotton production of the State of Georgia, by R. 11. Loughridge. This report contains an agricultural map of Georgia, slKJwing the distribution of the various kinds of soils in the State. A similar map for South Caro- lina is found in the Report of the Tenth Census, vol. G, a report on the cotton production of South Carolina, by Harry Hammond. A similar map is also given in the same volume for the State of Florida, being a report on the cotton production of Florida, by Eugene Allen Smith. A study of these maps, with the remarks made thereon, together with the analyses of tlie soils which follow, will give a fair idea of the agricultural ijossibilities of the States mentioned. NOTES ON THE SOILS. In the table of analyses of soils which follows the localities in which the samj)les were taken are also given. Some additional notes have been furnished in i-egard to some of the samples, which will be of interest. For these notes 1 am indebted to Capt. D. G. Purse, of Savannah. Duke Station. Fla.— Samples Nos. 22646-22647. The top soil is in the top of the bag and the subsoil in the bottom of bag, with a string in tlie center to keep them sejiarate. The water in this locality is soft, and the land is what is classed as high flat woods, sloping to the north. The field from which this sample was taken consists of abont 40 acres and has been under cultivation for about fifteen or twenty years. No fertilizer was used until this year, when a cheap manure, consisting of rock jihosphate, kainit, and cotton-seed meal, thorouglily mixed together, was employed. Recently a little compost was applied. The crops that have been raised in this field are corn, cotton, and sugar cane. The railroad runs through this field and the cut is from 1 to 5 feet deep, and there is quicksand in it in wet weather. No rocks or stones in land. Griffing Station, Fla. — Samples Nos. 22048-22649. Prepared in the same manner as samples Nos. 22646-22647. The land is high flat woods, slightly rolling. Sample taken from land sloping north and south, witli ditch between. Wells 8 to 10 feet deep; soft water. This sampk^ of soil is frcim a virgin field, planted a])out two months ago in peaches. The land has l)een plowed but once. Fertilizer has never been used. Land free from rocks and stones. Samples Nos. 22650-22651 are from Milejiost ;58 and taken from virgin soil. Bui. 70, Bureau of Chemistry, U, S, Dept. Agr.

High, flat woods. Fertilized with a cheap manTire, 200 pounds to the acre. Crops raised m this field consist of cotton, corn, and sugar cane. I would call your attention to the fact that in this field there is a disease in the cotton called " " l)lack root. ' ' The root turns Idack and the plant dies. Mr. Britt worild like to know if this is caused by the soil; if so, what can be done to remedy it. Samples Nos. 22654, 22655. This sample is from Milepost 46. High, flat woods, and remarkably rich. The sample was taken from \'irgin soil in the pine woods. Water soft. Well 10 to 12 feet deep. The farms from which these samples have been taken have from 1 to 3 acres in sugar cane, and they raise from 10 to 12 barrels of sirup to the acre. It must be remembered that the section of the country throiigh which the Jackson\nlle and Southwestern Railroad runs is entirely a new coimtry, nearly all of the land being \nrgin , with here and there a few places which have been in cultivation for years. This virgin soil with a little assistance should produce from 10 to 15 barrels of sirup to the acre. Egypt. Ga. — Samples Nos. 22658, 22659. Land owned by Mr. E. E. Foy. This land has been in cultivation twentj^-eight years. This year and last it was planted in cane. It was planted in rye in 1899, on which no fertilizer was used. The fertilizer iised on cane crop both this year and last was stable manure, about a ton per acre, supplemented with about 200 pounds each of cotton-seed meal and acid phosphate. Land level and sandy. Adrian, Ga.— Samples Nos. 22660, 22661. Land owned by Capt. T. J. James. Land at present planted in cane; also last year. Formerly planted in corn and oats. Each crop fertilized with about 200 poimds of guano. Land level and sandy: free from stones; not very well drained. This land has only been in cultivation about five years. Americus, Ga. — Samples Nos. 22662, 22663. Land owned by Mr. Tawson; rented by Stapleton for several years. Land has been in cultivation twenty years or more. A small creek within 300 yards of the edge of the field. Rather rolling, with a stiff clay subsoil. The field from wliicli this sample is taken is typical of the land ujion which cane is usually grown, rather than typical of the general soil of the locality. This land was in cane last year, but this season is not idanted in anything. Fertilizer u.sed last year and the year before consisted of 200 pounds of cotton-seed meal and 150 pounds of acid phosphate. Albany, Ga.— Samples Nos. 22664, 22665. Land owned by Mr. Morris Wesloski. This sample is taken from land which is at present in Irish potatoes and was in cane for two years preceding. Fertili- zer used on the land this year was about 600 pounds of guano per acre. On the cane the same fertilizer was used, about 400 jiounds per acre. Land is level, a dark loam. Field from which sample was taken is typical of the whole locality. Hartford, Ala. — Samples Nt)s. 22666. 22667. Land owned by J. W. McKinney. Has been in cultivation about seven years. At present is planted in cane; last year in sweet potatoes. Samples taken from a 14 MANUFACTURE OF TABLE SIEUPS FROM SUGAR CANE. field typical of the locality. Rather rolling, sandy, well drained. About 200 ponnds of giiano per acre was used on both the cane and sweet potatoes. This was supplemented with a little stable manure. The three samples sent were taken from along the Chattahoochee River, Init in different localities, the samples differing considerably. Columbia, Ala. — Samples Nos. 32668, 32669. Land owned by J. F. Bowden. Samples taken from a field adjoining a creek, about 3 miles from the river. This field is typical of what is called the " upland "' bottoms, as distinguished from the first and second bottoms. This land is well drained, rather sandy and level. A very stiff clay siTl)soil about 3 feet below sur- face. Samples taken from an "oat field where corn was planted last year. One hundred and fifty pounds of guano was used on oats: about the same on corn. This land has been in cultivation for about fifteen years. Georgetown, G-a. — Samples Nos. 32670, 22671. Land owned by H. Lampley. These samples are from a field of •' second bottom " land. Is subject to overflow from backwater in very high water. Is aboiit one- fourth of a mile from the river. Land level, sandy. Has lieen in cultivation for thirty years or more. At present is planted in cotton; formerly in corn. Ferti- lizer used on ])oth crops was about 150 pounds of guano per acre. Brickyard, Ala.— Samples Nos. 33673, 33673. Land owned ])y Mr. G. M. Flournoy. Samples taken from "first bottom" land, about 1 mile from the river. Sul)ject to overflow every year. Has been in Johnson grass for seven years. A very ricli Idack soil. No fertilizer used. Cul- tivated for fifty years or more. Level, poorly drained. Fitzgerald. Ga. — Sample No. 33943. Land planted l)y R. A. Wilson. This soil has been treated in the manner pre- scribed in your letter. During the last three years I have grown on this tract corn, potatoes, peas, watermelons, and various other crops, the most of which have produced two or three crops each year. Of course, I fertilize each crop some, the fertilizer used being phosphate and German kainit and barn maniTre. Ambrose, Ga. — Sample No. 33944. Land planted by C. H. Buttler. Field has been in cultivation for six years, and the following crops have been grown: Cotton, corn, potatoes, and sugar cane. Beach, Ga.— Sample No. 33945. This soil was taken from a field now in cultivation for the third season. The first season it was planted in sweet potatoes with poor success, it being too wet for the crop. The second season it was planted in stigar cane, w^ith splendid results. It is now planted for the third season in sugar cane and promises to do well. Stable manure has been used freely each season. Douglas, Ga.— Sample No. 23946. This field has been in ctiltivation for thirty years. Corn, cotton, and cane have been the principal crops raised almost every year on this land. Good crops have been made almost every year. From 300 to 350 pounds of commercial fertilizer has been used almost every year. THE SOIL. 16 Samples Nos. 22949-22950. Soil and subsoil of red clay land. Oak and hickory; in cultivation sixty or sev- enty years. Samples Nos. 22951-22952. Soil and subsoil of poor sandy soil; in cultivation seventy years. COLLECTION OF THE SAMPLES. All the samples of soil were collected by Captain I*iii-se. Tlie fol- loAving directions were sent from this Bureau for secui-ing the soils and subsoils :"• Samples of soil are to be taken in the following manner, and the locality should be selected which is t^^'pical of the neighborhood. By means of a spade from 10 to 20 pounds of soil should be removed from at least half a dozen different ])oint.s in the field. Select tlKnu so as to have them as nearly typical of the whole field as possible. These samples should l)e put together on a hard, dry floor or oilcloth spread upon the ground, and thoroughly mixed, removing all stones and pebbles, sticks and roots. The residue should then be (luartered and one-quarter saved and the other three-quarters rejected. This quarter should again Ije mixed thor- oughly and again quartered, and this process continued until the sample weighs 4 pounds or less. This sample should be placed in a strong cloth bag, sewed up, and the franks I send you securely tied thereto. It is important to have also a sample of the subsoil in each localitj'. The sam- ples of the soil are taken to the usual dejith of plowing or to where the change in color of the soil is noticed — say. from 5 to 0 inches, according to circumstances. After the soil is removed from this excavation carefully, a sample of the subsoil should be taken to a depth of from 5 to 7 inches below the soil sample. The mix- ing and quartering of the subsoil should be accomplished in the manner described above. In each case the previous history of the field, the character of the crops groA\ni on it. and the kind of fertilization, if any, it has received are to be noted. There should also be given any prominent geological features of the neighborhood, the character of the stones and rocks, character of the water, contour of tlie land. etc. ANALYSES OF SOILS. Each sample was submitted to two chemical analyses. One, to deter- mine the total quantity of substance soluble in liot concentrated hydrochloric acid, was conducted according- to the methods prescribed by the Association of Official Atjrlcultural Chemists (Bui. 46, pp. 71 et seq.). The number of parts of potash and ph()s])horic acid soluble per million in N/200 hydrochloric acid was obtained according to the method of Moore (Journal of the American Chemical Society, vol. 24, No. 1, p. 70). These analyses were made by Mr. C. C. ]\[oore. The mechanical analysis of the soils was made according to the method of Osborne (Principles and PracticeofxVgricultural Analysis, vol. 1, X3p. 196 et seq.), by Mr. F. M. Cockrell, under direction of Mr. C. C. Moore 16 MANUFACTUEE OF TABLE SIRUPS EKOM SUGAR CANE.

The most striking feature exhibited by the above tabU' is found in the fact tliat the soils represented are abnost pure sand. In one instance more than 9!) per cent of the soil is insoluble in stronjr, hot hydrochloric acid, while the number of soils containinji: inoi-e than !»5 per cent of insoluble matter is very large. The only soils in the list which are not decidedly of a sandy nature are Nos. 1^2450, 22-454, 2265G, 22657, 22(;63, 22665, 22671, 22672, 22673, 22950, 22957, and 23579. Of these a few are distinctly vegetable or liuraus soils, viz, 22656, 22657, and 22663. All three of these soils contain large quantities of humus and other organic matter. The second characteristic of the soils, Avhicli is very prominently shown in the lablc of analyses, is the absence of any large? (luanlity of potasli soluble in hot hydrochloric acid. Only the following soils contain notable quantities of soluble potash, viz, 22449, 22663, 22672, and 22673. Phosphoric acid is also deficient in most of the soils, but not to the same extent as potash. One of the soils find the subsoil going with it, viz, Nos. 22453 and 22454, have a very high quantity of phosphoi-ic acid, and these samples, as will be seen, were from Florida, in the vicinity of the heavy phosphate deposits of that State. The other mineral constituents of soils are less important, viewed as plant food. Two of these, however, are found constantly in j)lants, viz, lime and magnesia. As is to be expected in soils of this charac- ter, these two mineral constituents are deficient in cjuantity as com- pared with the standard of soils of the usual textui-e. In a few of the soils there is an abundant supi)ly of iron and alumina, and these could be classed as clay soils in which the percentage of clay is not ver}^ large. Among the most prominent of this type are Nos. 22656, 22657, 22663, 22672, 22673, 22943, and 23579. The percentage of nitrogen in all the soils, with the exception of two or three of the vegetable soils, is quite low, and also, as would be expected, the quantity of humus. In only tlii-ee instances does the percentage of humus rise above 3. Evidently these are soils which are not well suited to retain niti-ogen constituents foi- any great length of time, in fact, one of the chief physical characteristics of these soils is the ease with which water percolates through them and the consequent rapidity with which soluble substances are leached out during heavy rains. In the estimation of i^otash and phosjihoric acid, by dilute hydro- chloric acid, the purpose in view is to secure some idea, not of the total quantity of these plant foods present in any given sample, but of their relative availability. Pot experiments made by this IJureau have shown that a reasonably good approximation to the availabh^ plant foodrin a soil maj^ be made by treating a sample of it with N/200 20 MANUFACTURE OF TABLE SIRUPS FROM SUGAR CANE. hydrochloric acid at a constant temi^erature of 40° C, with con- tinuous shaking-. I'his process applied to the soils in question show- that the potash, although xu'esent in extremely minute quantities in most of the soils, is very highly available; that is, practically all the potash in the soil is at the disposition of the growing plant. On the contrary, the phosphoric acid which exists in these soils, as a rule in much larger quantities than potash, has a very much lower degree of availability. Therefore, while a growing crop might take out all of the potash in a soil, it would remove only a small quantity of the phosphoric acid pi-esent. In other words, the phosphoric acid which is present is so locked up in mineral combination as to be largely insoluble in dilute, cold, or lukewarm hj'drochloric acid at the tem- perature mentioned. These figures show that the potash present in the soil is practically all availal)le for the growing crop, and the crop therefore takes as much of it as may l)e necessary to meet its demands. On the con- trary, the growing crop is able to take only a small fraction of the phosphoi-ic acid pi-esent. Hence it appeal's that the general rule to be followed in the case of these soils is to give them largely the two essential elements of plant food which are least available in the quan- tities in which thej^ exist in the soil, viz, phosphoric acid and nitrogen. Of course there are many of these soils in which potash is also defi- cient, but it is evident that the quantity which is present, although minute, is very highly available. Ah a rule, therefore, if any one of the three essential elements of plant food is omitted in the fertilizer applied it would be safer to leave out potash than either phosphoric acid or nitrogen. At the same time it is evident that in many of the cases the judicious application of i)otas]i would be highly advisable. j In this connection, however, it must be remembered that, as a rule, l)lants take a lai-ger quantity of potash from the soil than of phos- phcn'ic acid, and hence the presence of available potash, as deter- j mined by the dilute hydrochloric acid method in two or three times the quantity of available i)hosphoric acid, would indicate that the soil was in equal iiee(] of both phosphoi'ic acid and potash in case either was necessary to nuike the crop. Illustrations of what is meant l»y this can best be drawn from the table of aiuilyses abo^e. Koi- instance, in No. i'2441 the potash solu- ble in hydrochloi-ic acid is o-J pacts per million and the phosphoric acid 14. 'I'liis soil needs potash ev(!ii more than phosphoric acid. In the next number the proportions are as 85 to 20, respectively. This is a soil in which phosphoric acid is probably needed more than potash. In the next number the i)roportions are 20 to 5. Here both elements are deficient, but phosphoric acid in a more marked degree than potash. P^'or the next number the proi)ortions are 2!) to 20. This is a soil which needs especially potash. In Uio next numbers the pro- portions are as 50 to 1 and 51] to 1, and, in fact, in many of the numbers Bui. 70, Bureau of Chemistry, U. S. Dept.

ANALYSES OF SUGAR CANES. 21 down to 22450 the datM show that i)h<>s[)lioi-i(' acid is ui-geiitly iiccdod. Ill fact, there are very few of these soils in whieh the avaihible phos- phoric acid is as large as is i-eqiiired. The mechauical composition of tlie soils gives valuable data in regard to their physical texture and capabilities of sui)porting iilant life. A soil must not only have i)lant food in an available form which it can offer a growing crop, but it luustalso be of such a texture as to liermit the rootlets of the jjlants to penetrate all parts of tlie surface in which the available plant root is held. Sandy soils are easily per- forated by the roots of plants, and for this reason, although as a rule they are deficient in plant foods, by judicious treat iiiriil they may be made to yield large and remunerative crops. In the table of analyses the mechanical composition ol' Wxo soils shows the relative proportion of particles of given diameters. The first column shows the percentage of particles larger than 0.2.") mm, tlie second those smaller than 0.25 mm but larger than U.IO mm, and so on throughout the list. When the iiarticles become too small for con- venient) measurement, they are separated by suspension in water. Those that are smaller than O.ooi; mm. which will not float for cnghteen hours, are given in one column and those smaller than O.ooi; mm. which will float for eighteen hours in another. In the last two columns is given the loss on ignition, which includes both water and organic mat- ter, while in the last column is given the ])erceiitage of watei- in each sanqile at the time of analysis, liy subtracting the percentage of water from the total loss on ignition the relative quantity of organic matter in each sample can be obtained. ANALYSES OF SUGAR CANES. Through Capt. I). (4. Purse, of Savannah, arrangements were made to secure samples of sug.u- canes grown, not onh' in the localities where the samples of soil w(;re secured, but also in many other places. Instructions for securing and forwarding the samples wei"e ])r('])ared as follows: When the fane appear.s to be matured, or at the nsiial time of harvesting, select a stalk from an inside row. Tlit> stalk selected should be from a jjart of the field that represents average conditions. Cnt the stalk, after removing the leaves, into several short pieces and. imme- diately after, dip the ends of the jiieces into melted paraffin, or. preferably, into a mixture of paraffin and beeswax. Wrap the pieces of cane carefully in strong paper. Fill in the blanks on the l)ack of the shipping tag herewith and attach it to the package and mail the latter to the United States Department of Agricul- ture. No postage is required. The packages should be mailed so as not to reach Washington on Saturday or Sunday. Numerous samples of cane, secured in accordance with these in- structions, were forwarded for analysis, the first samples reaching IP.miHi' '.'>.! 22 MANUFACTURE OF TABLE SIRUPS FROM SUGAR CANE. the laboratory early in X()V(Miil)er, 1001, while the last .samples were not reeeived until January, r.)()2. Samples were received from the States of Alabama, Florida, (Georgia, and South Carolina. These samples, on their reception at the laboratory, were immediately sub- jected to analysis for the purpose of determinini^: the specific gravity, sugar or sucrose, and reducing sugar or glucose, contained in the juices thereof. From the data secured the coefficient of purity — that is, the percentage of pure sucrose or sugar in the dry mattei- of the juice — was calculated. The juices of sugar canes may bn said to comprise about W) per cent of the total weight of the canes. Therefore the percentage of the ingredients given in llie canes themselves would be, in round numbers, 10 per cent less than in the juice. For instance, if the sucrose or pure sugar in the cane juices amounted to 13.2 per cent, the corresponding percentage of sugar in the cane would be 11.!) per cent. The analytical data, w hich were determined chiefly l)y Mr. Arthur Given, assisted by Mr. F. M.

There can be no legal nor technical objection to the manu- facture and sale of any kind of a table sirup, not injurious to health, made up of such ingredients as the manufacturer may desii'e to use PKOBLEMS WHICH NEED FUKTHER STUDY. 31 and the puivliaser to consunic. In oilier words, a market should be just as free to mixtures of glucose, melted sugar, and flavoring and coloring extracts, as to a pure sirup made diiectl}' fi-om the cane or tlie iiuiple tree. Tlie only poinl to be kept in view is that these manu- factured articles should be sold under their <>\\ ii luimes and labels and should not be allowed to imitate in name oi- bibel tlie qualities of the i3ure article. The maker of a pure table sirup fi-om cane or other source has no right to demand that the market be closed to ai'tificial mixtures oi- ])roducts intended for a similar pui-pose. On the other liand, the maker of these artificial products certainly has no right to utilize the name and label of the genuine article. Every class of busi- ness is perfectly legitimate if carried on in a legitimate mannei-, and the market should be open and free to all. A complete study of Hie character and extent of the adulteration of sirups is therefore tlie first step toward placing upon the market and securing the sale of the pure and unadulterated article. (2) The agricultural problem, from llic agricuitund-chemieal ])oint of view, is also important . This prolilem has been discussed to a cer- tain extent in this bulletin, and an extensive study <»f Hie character of the soil and the chemical properties of the product has been pre- sented. It is evident from this examination that extensive fertiliza- tion must be practiced on soils of the kind indicated in order 1o secure large and remunerative crops. Only a thoi-ough experimental trial of the fertilizers indicated by the analyses in various combinations and mixtures and applied to various kinds of soil will secure results which will enable the practical farmer to utilize tlie agricultural facilities which are placed at his disposal in the most economic and effective way. Numerous plot experiments in Avhich fertilizing materials of diiferent kinds are applied in definite quantities and under controlled conditions will be required to establish the genei-al princijiles which will enable the farmer to use his fertilizers in the most advantageous manner. These experiments all require analyses of the fertilizers used, their measurement in definite quantities, and their api)lication in a thoi'oughly scientific way. (o) The thii-d problem in connection with a study of this kind is the improvement of the milling ju-ocesses in order to secure the largest possible expression of the juice of the canes. At llie i)reseiit time single mills of three rollers each are almost universally emiiloyed. There are no data which are sufficiently extensive to enable us to esti- mate the quantity of juice secured. It is evident, liowever, that the percentage of extraction is somewhat low, and probably accurate measurement would show that in many cases not over 00 per cent of the juice contained in the cane is expressed. The bagasse coming from mills of this kind is entirely too wet to burn effectively. In fact, in the whole country in wliich sirups from sugar cane are manufactured fuel is so cheap there is little economie 32 MANUFACTURE OF TABLE SIRUPS FROM SUGAR CANE. importance in burning tlie bagasse. Since, however, the bagasse accumnlates and must be removed, it is evident that if it can be burned and furnish the heat for manufacturing oi)erations it would be the most economical way of disposing of it. The establishment, there- fore, of milling processes which would leave the bagasse in a condi- tion to be burned would not only increase the total output per ton of cane, but also diminish the expense of manufacture. (4) Tlie fourth problem which presents itself for investigation is the determination of the best methods of clarifying and purifying the juice j)revious to evaporation. This is a problem which has been worked out pretty thoroughly, and there is little left to study except mechanical and technical details. The principles of neutralizing the free acids present in the cane juices for the purpose of facilitating clarification must, however, be applied in a somewhat different man- ner in sirup manufacture than in making sugar. It is desirable in the case of sirups to leave the juice decidedly acid. This is necessary for two reasons. In the first place, the acid juices make a light- colored and more presentable looking sirup, and second, in the process of evaporation the free acids of the juices tend to invert certain ({uantities of the sucrose and thus render the finished product less liable to crystallization. To just what extent the neutralization of the natural acids can l)e carried to secure satisfactory clarification and yet leave sufficient acidity for the purposes mentioned above is a j)roblem wliich demands careful study. (5) The linal problem which demands consideration in these studies is to secure a sirup of uniform character, both in coloi' and consistence, and to put it in packages in such a way as to jjrevent fermentation during warm weather. When these two conditions are secured the marketable value of the sirup will be vastly increased. The first con- sideration woul, Special Agent of the U. S.

The aim has been to present a practical and popular treatment of the subject, so far as the time at m}' disposal permitted me to carry the inquiry. Necessarily this report must be fragmentary and incom- plete, as one person could not possibly coyer the entire ground in a single season. From the complex nature of the work undertaken, it has seemed best to present two reports — the present one dealing with the economic and practical data collected, and a second I'cport dealing witli the more technical study of methods of fermentation and related matters, such as a study of the organisms commonly found in apple juice, and the importance of the isolation, culture, and employment of pure yeasts in the manufacture of ciders and other fermented beyerages made from fruit juices. A discussion of the organisms causing mal-fermen- tations will also be attempted. Very respectfully submitted. WiV- B. Alwood, Special Agent. Dr. H. W. Wiley, Chief., Bureau of Chemistry, U. S.

A well-made cider is a beverage which is appre- ciated by all and one which is within the reach of ever}- possessor of an orchard. Cider is also a beverage which mav l)e manufactured without the supervision of the excise officials. It is thus an industry which can be widely extended and whose development will make the growing of fruits more prohtable. It is evident that the principles which underlie the conduct of the fermentation of apple juice in order to secure a product of a definite chemical composition also apply to the juices of other fruits, such as pears and peaches, and thus a Inilletin of this description affects, in general, the fruit interests of the country wherever the juices of fruits are employed for potable purposes. Up to the present time the manufacture of cider in the United States has been conducted largely by empirical methods. Little has been done toward the study of the chemical composition of the fruits, the fresh juices, the fermenting musts, or the finished products. What is true of wines is also true of ciders and other fermented fruit juices, viz, that their excellence and healthful ness are dei)endent entirely upon their chemical composition. The changes which take place in fruit juices during fermentation are essentially chemical, and are produced by ferments, which in these instances ma}" be regarded as chemical reagents. In order that the manufacture of cider maj^ be conducted in a more systematic and scientific manner in this country, it was deemed desir- able to study the best processes employed in foreign countries, espe- ciall}^ in England, France, and Germany, which are the principal cider- producing countries of the world. To this end, Mr. William R. Ahvood was employed by the Secretary of Agriculture as a special agent to act under the direction of the Chief of the Bureau of Chemistry, and was detailed to study the actual processes of manufacture in the coun- tries named, as well as to conduct extensive experiments here. Mr. Alwood, in addition to collecting valuable information of a practical nature, has also ))rought together the scattered chemical data found in difficultly accessible reports and papers, so as to make them available for use. 5 6 It is evident that a careful study of the data thus collected will be of great service to our own manufacturers in showing- them the methods which experience and scientific studies in foreign countries have deter- mined to be the best for the production of a wholesome and palatable article. This bulletin serves as an introduction to a more detailed study of the best methods of fermentation, cellar treatment, and preservation of cider products, together with a more detailed chemical study of the fruits, the musts, and the finished beverages.

The subject of working u}) the low-grade apples left as an unmer- chantable residuum of the apple crops grown in the United States has for some 3'ears attracted the attention of the writer, and experimental work on this subject has been done in the horticultural dei)artment of the Virginia Agricultural Experiment Station for the past eight years. Several preliminaiw reports of this work have been published* from time to time, intended to encourage local etiorts to utilize the large quantities of unmerchantable fruit produced every year when there is a fruit crop. These preliminary efforts served to awaken a strong interest in the possibilities of making a pure sound cider from our apples, which «Sir George Bird wood quoted by Cooke in "Cider and Perry," p. 3. l> Bulletins 48, 57, and 71, Va. Agr. Expt. Station. 11 12 might serve as a light American wine so cheap and wholesome as to be usable by everybody, and as a secondary product from such fermented cider a tine apple vinegar to displace the enormous quantities of chem- ical vinegars which find sale in those States where their manufacture and sale are not restricted by statute. The importance of utilizing our low-grade apples can only be appre- ciated after realizing the proba])le ciuantity of this fruit produced in the United States. QUANTITY OF APPLES PRODUCED IN THE UNITED STATES. It is impossible to present an accurate estimate of the apple crop, of the United States. The Census Bureau has not in the past gathered statistics concerning this crop which can be said to cover this subject with any degree of completeness; nor has the Department of Agri- culture been able up to the jDresent time to furnish the data desired. The difficulties grow out of the nature of the crop itself. The apple is a fruit grown almost over the entire cultivated area of the country, but in many instances only in a haphazard maimer and as a crop of secondary importance; hence any attempt to deal with it accurately from a statistical standpoint must of necessity fail because of the immense labor involved and the lack of definite information among the farmers themselves as to the amount of their crops. The growth, however, of commercial orcharding, along Avith the practice of packing and handling the merchantable crop in barrels and boxes, has made it possible to gather with some degree of accu- racy statistics of the merchantable apples which enter into commerce. These statistics have been collected by the Orange Judd Publishing Compan}' with perhaps more care than by any other concern in the country, and from their tables" the followino- data are taken: The greatest crop ever recoixled in this countiy appears to have been that of 1896, and comprised 69,070,000 barrels. It also appears that the average merchantable crop of the countr}- is in round numbers 50,000,000 barrels, or about 110,000,000 bushels, annually. If this quantity enters into commerce through avenues sufficiently definite to give it a place in the statistics of trade, how shall one esti- mate the millions of bushels which are unmerchantable, or which enter commerce untraced and unrecorded^ It is, then, very evident that we have no means of estimating with reasonable accuracy the grand total of our apple crop; but well-informed persons will, I think, agree to the statement that, on the whole, not more than about 60 per cent of the fruit actually grown in this country finds its way into chaimels of commerce in such a manner as to appear in general statistics. If this be a fair suj)position, then nearly 100,000,000 bushels of this fruit are either consumed without having "American Agriculturist, October 27, 1900, p. .S9S. 18 passed through the channels of cominerce mentioned above or go to waste on the farms wh(M-(^ grown. DISPOSITION OF THIS FRUIT. First of all, a largo part is consumod whore grown or in local markets. Largo quantities ar(> consumod in the manufacture of evaporated fruit and of cider, both for drinking purposes and for conversion into vinegar. In certain districts largo (piantities of low-grade fruit are used for canning and making marmalades, butters, jollies, etc. A great quantity of this unmerchantalde fruit, especially in the South, goes into the preparation of sun-dried fruit. In some years 200 tons of this sun-dried fruit are shipped from the little station of Chris- tiansburg, Va., S miles from the experiment station at lilackslnirg. Perhaps the data" in regard to merchantable fruit produced have been collected with as great accuracy in Virginia as in any other State. These data show that our crop of 1897 reached about 281,SiS9 barrels. These figures are not quite high enough for that year, as the total merchantable crop was about 300,000 barrels. Supposing this to have been 60 per cent of the total crop, about 1,400,000 bushels of apples were produced in Virginia that year. Of this quantity about 000,000 ■bushels were localh'^ consumed or went to waste. Formerlv the esti- mates were much larger, being based on the Eleventh Census,'' but we now know that the census tigures of 1890, so far as they relate to apple production in Virginia, are inadequate. Excepting the sun-dried, evaporated, and canned fruit, the apple products just enumerated are generally adulterated in tho United States, either bv the use of other than vogotal)le substances or bv the mixture of diflerent fruit and vegetable substances, and the use of various preservatives and substances which, if not preservative, serve to mask defects in quality and cheapen methods of manufacture. This adulteration has l)ecome so notorious as to groatlv injure a logitimato trade which should be a most proper and natural outlet for this large portion of our apple crop Avhich falls below merchantable grade. Tho important practical l)oaring of these secondaiT industries upon fruit growing in our country has led the w^'iter for a number of 3'ears past to devote some attention to their study, with a view to determin- ing the principles Avhich lie at the basis of the practical maiuifacture of those products on the farms or in small cooperative factories placed in tho midst of tho districts which furnish tho raw material. To this work the authorities of tho Virginia Agricultural Ex})orimont Station have given all the support possil)le with the funds available, and the work has progressed sufficiently to enable us to give practical instruction of a reliable character to our students, especially along the lines of canning and making l)utters and marmalades. But on some "Bulletin 101, Va. Expt. Sta. & Bulletin -18, Va. Expt. Sta. 14 lines we had up to the spring of 1900 made little or no progress, most conspicuous among which were the practical methods of fermenting ciders and vinegars, and the ])iology of the alcoholic and acetic ferments. All questions relating to products from fruits received consideration in m}' work abroad, but particular attention was given to a practi- cal examination of the methods of manufacturing cider in France, German}', and England, and a study of the biology of alcoholic and acetic fermentation of fruit juices, either for the manufacture of beverages or vinegar. This paper deals with the cider investigation in its practical bearings, and other questions of interest are reserved for a subsequent report. ACKNOWLEDGMENTS, In the investigations made abroad I was almost without exception received in the most cordial manner by both public officers and private individuals whom 1 had occasion to call upon for assistance; and while 1 can not mention by name all persons who gave assistance, I wish to extend special thanks to the following: Tiie diplomatic and consular officers of our Government at London, Paris, Frankfort, and Berlin extended every courtesy, aiding me by introductions and by furnishing special information, all of which assisted very much in the accomplishment of Jthe work in hand. In England I was received in a most courteous manner and, barring some slight exceptions, was shown over the factories and given such information as was desired. Among those who thus assisted I wish to mention especially the following: jNIajor Craigie, of the board of agriculture; Mr. F. H. Hall, of the agricultural col- lege at Wye; Hon. C. W. Radcliff Cooke, of Hellens, near Dyuiock, Herefordshire; Mr. Charles D. Wise, of W^inchcombe, Gloucestershire; Mr. F. J. Lloyd, London, consulting chemist of the Bath and West Society; R. Neville Grenville, esq., But- leigh Court, Somersetshire; Mr. Frederick George Farwell, Bath; Mr. A. E. Beach, Winchcombe, Gloucestershire; Mr. T. W. Beach, Ealing Road, Brentford, London; Mr. H. P. Buhner, Ryelands, Herefordshire; Mr. Henry Weston, Much ^larkle, Herefordshire; Mr. John Watkins, Withington, Herefordshire. In France I was very courteously received by Mr, Leon Vassilliere, director of agriculture in the ministry of agriculture, and by him introduced to others. Prof. A. Kayser, of the National School of Agriculture, Paris, extended ever}^ courtesy' in his laboratory, and permitted me to note the methods of his work and stud}' the litera- ture of his department, Mr, A. Triielle, of Trouville, Calvados, assisted me in securing information and special literature, Mr, A. Power, director of the Grand Cidrerie at Saint Ouen-de-Thoul)erville, permitted me to study the methods of the factory, and gave nuich assistance, Mr, E, Herissant, director of the Practical Agricultural School of Three Crosses, at Rennes, Brittany, in like manner explained Bui 71 Bureau of CheiTiistry.

Mi\ Isidore Guibout, and his son, Mr. Joseph Guibout, peasant farmers of Danestal, Calvados, gave me every opportunity to study the conditions and technique of cider making on the peasant proprietors' places. ^Nlr. J. M. Buisson, secretary of one of the horticultural syndicates of France, extended many courtesies, and introduced me to manv men from whom information could be o))tained. In Germany I am first of all indebted to Director K. (ioethe, of the Royal Pomological School, at Geisenheim (PI. I, iig. 1), for courtesies extended at that institution. I am also especially indebted to Prof. Dr. Julius Wortmann. director of the laboratory of plant piiysiologj'' at Geisenheim, for his assistance in regard to every part of my inquiry and for instruction while working in his la))oratory. From Prof. Dr. Richard Meissner, then assistant to Professor Wortmann, I received much personal assistance and kindly counsel. Prof. Dr. Paul Lindner, of Berlin, also extended courtesies at the Imperial High School for Fermentation Work, for which lam deeply indebted. Of the manufacturers in Germany I wish to especially remember the Brothers Freyeisen, of Frankfort, for permitting an examination of their work and factories in detail. Acknowledgments are also due to Mr. Fritz Batz, Neuenhain, Taunus, and Mr. C. H. Schmidt, of Schierstein, Rhinegau, for extending like courtesies at their factories, CLASSIFICATION OF CIDERS. Wines have long since become well recognized by specitic names which, within limits, denote certain characteristics, more or less con- stant; Init with the fermented juice of the ap})le in the past all has been cider, whether good, bad, or indifferent; and even 3-et onl}" those who are well informed on the question are aware that there arc ciders and ciders. To the fact that ciders have not in the past l)ecn developed on special lines and classified, we owe much of the misunderstanding in regard to the possibilit}^ of making a good beverage from apple juice; but to the fact that so much vilely adulterated or chemically concocted stuff is put on the market as a drink, we owe, in much greater degree, the general misunderstanding in regard to this product in our country. IX FRANCE. The French attempt to classify ciders as "pure juice," '• marchand," and "boisson." To say that this classification is well observed is wide of the truth. The first named is intended to be pure cider of a special quality, made from the finest fruit. It should contain 0 or 7 per cent 16 of alcohol, and may be made as still cider — i. e., fermented '"dry" (sec); as "mousseux," cider bottled before all the siio-ar is exhausted, and so handled as to develop and retain a certain quantity of gas; or as cider "champagnise," which has received more special treatment than ordinary "'mousseux" and often is, in fact, dosed with sugar to fortify it. The cider "marchand," or simply cider, should contain from 4 to 5 per cent alcohol, and is made from fruits of medium quality; or, as more often happens, if rich enough, it is diluted by mixture of the second pressing with pure juice. This is the cider of commerce as it ordinarily leaves the manufacturer, but after it pays the octroi or tax and enters into consumption in the city, it may lie, and often is, diluted and becomes quite a different article from that which leaves the manufacturer. The '"boisson," as applied to a cider, means the juice of second or even third pressing of the pomace. It is fermented comparativ^ely "dry," contains about 2 to H per cent of alcohol, and is the ordinary cider of the common people, especially laborers in both country and city, in the cider districts. It is often furnished in large quantities to the farm laborers, and if so handled as to retain considerable gas, or artiliciallv charged, it is an agreeable light drink. "Boisson" is also very often called "petit cidre" (small cider). A poor cider is made from the unpared chopped American dried apples and from the dried cores and parings we sell to France, by treating this stock as follows: About 10 kilos (22 pounds) of the dried stock are macerated in a vat containing one hectoliter (about 26 gal- lons) of water with addition of some raisins or sugar to suit the taste of the manipulator, and this is then permitted to ferment slightly in mass to extract the desired substances, and the liquid is expressed and treated as in case of low-grade cider. The beverage made in this man- ner is restricted by law to 3 per cent alcohol content and is a cheap drink, used mostly at low-class restaurants and for laborers. This low- grade apple stock sent to France is also used to macerate with hard cider to restore in part its quality ]»y inducing new fermentation; but not the slightest evidence was found to substantiate the supposition heretofore frequently advanced, that this poor apple stock, or that even good sun-dried apple stock is used to make French wines or to adulterate them. IN GERMANY. Cider is classified in Germany into common cider, or "apfel wein," "export apfel wein," and "champagner apfcl wein." One also con- stantly meets with such names as "Speierling aj^fel wein," "Boers- dorfer apfcl wein," and others. These grades of cider do not correspond closely with the classes or grades of French or English 17 ciders. These names are, in fact, more to l)e relied upon as having a definite meaning so far as the strength and purity of the article is concerned. The common cider of Germany is made just as they make ordinar}' light wines, and their cider is, in fact as well as in name, a wine. It will show from 3.75 to 4.50 or nearly 5 per cent of alcohol, varying with the character of the fruit, and the ordinar}- cider is a dry, light wine of very insipid taste to the American palate when not charged with carbon dioxid. These ciders are kept in casks and drawn as wanted. The "export apt'el wein'' is made practically in the same manner from selected fruit, but is either bottled when there is still sugar enough to saturate it with gas or is saturated artificially. It may show 4.5 to 5 or 5.5 per cent of alcohol and is a still light wine. The "champagner apfel wein'' or '"schaum apfel wein" is much like champagne from grape wines. At a proper stage the cider is clarified, sugared, and bottled, and carried through the processes described hereafter. The ''"Boersdorfer apfel wein" is simph' a name given to indicate a product supposedh^ made from the Boersdorfer apple, but it was not evident that this brand had any special qualities not found in a good export grade. The "Speierling apfel wein," however, is a cider made by using a small proportion of the juice from the wild fruit known to botanists as Pyrus {Sorhus) domestica. This tree was found growing to giant pro- portions on the Taunus mountains about Soden. The fruit when fullv ripe and touched by frost becomes very mellow and has an agreeable flavor, but before ripening it is characterized by a pungent, acrid juice so rich in tannin as to remind one of the unripe American per- simmon in its effect on the mucous membrane of the mouth. The juice of this wild fruit is added to apple juice in small quantity, not over 5 per cent, and by reason of the tannin contained is thought to produce a finer cider, which is more easily clarified, and to furjiish in the finished product a superior flavor and bouquet. (PI. I, fig. '1.) It can not be said that the German ciders appeal to the American palate, 'with the exception of their champagne ciders and the very finest of the other grades; but that the}' are well-made standard goods is most certainly true. In Germany great quantities of fresh, partly fermented cider are offered at the restaurants in the fall season. This they call '' rauscher" or "siiss apfel wein" (smoking or sweet cider). The brothers Freyei- sen stated that they sold ordinarily about 5.000 hectoliters of such cider each year in Frankfort during the making season. This would be about 132,000 gallons. 17247— No. 71—03 2 18 IN ENGLAND. In England a strong effort is being- made to bring about a better understanding of the importance of grading ciders in accordance with some standard. But it could not be learned that any generally accepted classification had been adopted, further than that the Bath and West Society, which holds the only fair at which any considerable exhibit of ciders is made in England, recognizes two classes, i. e., those show- ing 4 per cent of alcohol or more, and those Avhich show less than 4 per cent of alcohol. The latter are called small cider by their chemist, but this word is not accepted in the English trade. From analyses made by the United States Department of Agriculture of samples selected at Bath, at the annual show in May, 1900, it appears that the classification that year was not based on accurate chemical data, or else the samples were confused in handling. There were goods of both classes, bottled and in casks, and it appeared that the classification was rather artificial, being often determined, not by the quantity of alcohol a certain quality of juice will produce, but by the stage at which f(n'mentation had been arrested. The analyses of ciders from the Bath and West exhibit of 1900 show conclusively that fermentation had not been normally carried t)ut. but that it had been arrested by artificial means. In fact the cider of commerce in England, except in some few cases, has no recognized standard. There seems to be a very unwise effort to cater to a demand for a sweet liquor showing only 3 to 4 per cent of alcohol. If made from a good quality of fruit and unadulterated, such cider must still contain considerable unfermented sugar, which renders it very unstable and difiicult to handle in shipment, except as sterilized bottled goods, unless treated sufficiently with preservatives to check fermentation. There is another alternative equally bad, namely, to ferment the juice dry, dilute with water, and dose with saccharin to produce the sweet taste desired. It was said that this was practiced, but no proof of it was seen. In England, however, excellent grades of bottled ciders were found, both still and gaseous. Some of these were made from special varie- ties of apples, as Foxwhelp, a very old English cider apple, or Kings- ton Black, but more often they were made from the mixed fruit of the district. Eight examples of these ciders are shown under sample numbers 32 to 39 (see p. 111). These were really fine ciders, some dry, some bottled with a small percentage of unfermented sugar, and others sugared in the process of champagnizing. A sparkling cider is not necessarily a sugared article, but, if i)ure, is best produced by bottling before fermentation is complete. It is then a normal French " mousseux." This grade can, however, be produced by charging with gas artiliciall}- when bottled. A cham- 19 pagne cider is not, propei-ly speaking, a jnire r-idor. ))iit is fortified hy addition of sugar. It appears that even in the best cider districts of Knghmd there are no really accepted names for ciders which can be depended upon hy purchasers. The name of the maker is practically the only mark worthy of consideration. This state of affairs, however, is in fair way to remedy itself, as the industry is rapidly developing on special lines, and certain class designations, such as still ciders, sparkling ciders, champagne ciders (both dry and sweet), of approximate alcoholic strength, will soon come to be recognized in the ti'ade. The Buhners, at Hereford, seem already to have reached a high degree of perfection in the preparation of their goods, and Mr. Charles Dacres Wise, at the estate of Lord Sudley, in Gloucestershire, was putting up a vevy excellent grade of both still and sparkling ciders and perry, the latter being made from the fruit of the pear. Nothing so interesting in the way of a countr}' plant was found as that of Hon. C. W. Kadcli tte Cook, at Hellens, near Dymock, Herefordshire. This country gentle- man, an ex-member of Parliament, was personally devoting himself to the manufacture of cider in a small way, with the most pi'imitive machinery, and yet producing a good sound article. It was, however, at Butleigh Court, the country seat of R. Neville Greenville, esq., that the best experimental work on cider manufacture found in Eng- land was seen. These establishments will be mentioned more fully under a subsequent head. PRINCIPAL CIDER-PRODUCING COUNTRIES OF EUROPE. When this inquiry in Europe was begun, the writer was somewhat imbued with the notion, so prevalent in the United States, that cider making- could onlv be regarded as a secondarv affair, a method of util- izing inferior fruit in the manufacture of a product of some local value, but not as an industrv of general importance. However im- portant the saving of the low-grade or unmerchantable fruit might be to our growers, it had not seemed as though cider making could be ranked as a oreat industrv. Interest in the matter had been mainlv aroused l)V what seemed to be a scientitic question of some moment, with fairly promising economic possibilities. RELATIVE IMPORTANCE OF THE CIDER INDUSTRY IN DIFFERENT COUNTRIES. In England evidences were found of an industrv fairly well founded, and in France and Germany there exists a great industry already well developed and employing millions of capital in the aggregate, with large areas of country devoted to growing cider fruits as an industry. France, by reason of the extent of its manufacture, is easily the leading cider country of the world, followed bv Germany, England, 20 Switzerland, United States, Canada, Austria, Grand Duch}- of Luxem- burg, and Spain, in order of importance/' The acreao-e of orchards in France can not be stated with any cer- tainty, but from estimates'^ of the total apple trees in Brittany, made by Frere Martial, of the Christian Brothers, of the Institute of Ploermel, it appears that in this proyince alone there are about 24,500,000 trees, and as this proyince makes about one-third the cider of France, a like ratio would carry the total number of trees up to about 75,000,000 for the entire cider country. After seyeral tours of the cider country of France the writer is pre- pared to belieye that this g-rand total is not too high. In the Calyados country, at some places, the face of the country is a forest of fruit trees, and frequentl,y the highways are also planted on both sides (Plate II). The product of cider yaries naturally with the quantity of fruit ayailable from year to year, but the mean annual production of France for twenty years (1879-1898) was 297,946,030* gallons, and the maxi- mum product during this time reached 695,388,430 gallons in 1893. From the French Goyernment reports it appears that 1,021,090 persons were entered as manufacturers of cider in 1898. The year 1900 saw one of the greatest haryests eyer known in France, and without doubt the fruit product surpassed all preyious figures. Consul-General Hertslet, of the British consular seryice,'" reporting in May, 1901, says that the production of cider in the 68 departments of France, in which apples are grown for this purpose, amounted to 647,000,000 gallons, in round numbers, from the apple haryest of 1900; but this estimate is doubtless not based on the final reports. The aboye figures as to production, except the last statement, are taken from those published by the French juinistry of agriculture, and are in no sense complete as to grand total. They represent the quantity w hich finds its way into commerce, so as to be reported to the Goyernment, but take no ac(?ount of the enormous quantity locally consumed. Each family m the great cider proyinces of Picardy, Nor- mandy, and Brittany, as a usual thing, makes its own cider or pro- yides for the same in such a manner that it does not enter into the figures reported to the Goyernment. It is probable that the ofticial figures include yery nearly the total of pure ciders, but the ''boisson," or low-grade ciders, are practically not represented in these statements. THE CHIEF CIDER-PRODUCING DISTRICTS. There are many statements current in the diflerent countries of Europe ab to the peculiar importance of certain districts as regards « Truelle, address before International Congress on the Cider Industry, Paris, 1900.

These statements at once recall state- ments of like nature in rej^ard to the quality of grape win(\s of certain districts. In the case of wines it can not be questioned that experi- ence has abundantly demonstrated the correctness of these chiims. Soil and climate certainly play a very important role in the production of all fine wines. Do they phi}' an ecjually important role in the pro- duction of ciders? .The chemical data on varieties ofrowai in difierent countries must in part answer this question. It was not found that any investigator had really undertaken a serious inquiry into this matter, and the manufacture of cider can by no means be said to have reached a stage of perfection which warrants definite conclusions of like value to those which o-ovorn wine makinw. It is very evident, however, that in certain districts where grapes will not grow to such perfection as to admit of their culture as a wine fruit, apples have for ages taken their place. European peoples are without exception consumers of wines in considerable quantity', some nations much more so than others. Hence, wherever the grape wine can not be successfully produced, there has been a more or less per- sistent effort to supply the demand for wine by using a fruit which will thrive under local conditions. The Fkench Cider Districts. In France the grape will not thrive in open culture to an}^ extent in the northwestern and northern provinces. Hence the provinces of Brittany, Normandy, and Picard}^, l3^ing in this part of France, are the chief seat of the cider industrv. These lie along the Atlantic Ocean, the English Channel, and the borders of Belgium. Normandy is in fact the principal cider country of France, and it is here that one finds the industry best developed in all its details. Also in this province has been developed a large number of seedling varie- ties of apples with the sole idea of cider making, and, though the face of the country is often a forest of apple trees, one never finds dessert or culinary varieties growing in these open plantations. The idea of commercial apple growing, as developed in America, is wholly imknown to these people. If a proprietor desires table fruit it is grown in his garden on walls or trellises, or on the walls of his residence or out- buildings, always in the form of cordons, espaliers, etc., never in open field culture. In fact, the orchard culture proper is for cider making, just as farther south in France the countrj" is in places occupied with vinej^ards for wine making. The varieties are seedlings from the apples grown here for centuries. It is only during the last fortA^ 3' ears that a study has been made of these various seedling varieties, and certain ones have been selected for propagation because of vigor, productiveness, and qualities desired in the processes of cider making. One finds certain varieties every- 22 where mentioned as the leading- sorts, and these are largely propa- fifated in nurseries. The orchards ev^ery where have the appearance so characteristic of seedlings of Pyrus mains (Plate III), and do not take on the character- istic appearance of American cultivated orchards. The trees are often scrubby, rough, and thorny, and so o\era-rown with moss and mis- tletoe that the}' seem to lit in well with the surroundings. The climate is oceanic, moist, and often dull from cloudiness, but never subject to great extremes of temperature. Much of the strictly orchard area in Calvados is found on a moderately ele\'ated plateau, characterized by low, undulating ranges of hills, with decidedly moist valleys. In this connection some extracts are quoted from a work by M. de Beaumont on Normandy, in which he speaks especially of Calvados, the department in which, perhaps, better cider is made than in any other of France: CALVADOS. General aspect. — Calvados lies with an exposure to the north and extends to the hills of the Department of ()rne on the south, and comprises many valleys and extensive jilateaus. These valleys, which are watered by six streams flowing from south to north, are separated from each other by chains of slightly elevated hills which decrease in height to the shore, where they are suddenly transformed into high cliffs of 30 to 120 meters (100 to 400 feet). Thriving, fertile, rich in prairies, this district offers many aspects of a charming country. The hills, the geological composition of which is very far from uniform, and which do not present the same characters in any two places, form three very distinct natural regions — the cretaceous, the calcareous, and the granitic. The first comprises the eastern part of the department. Chalky formations dom- inate in the country known as "'le Pays d'Auge," situated 1;)etween the frontiers of Eure and the valley ( )f the Dives. The arrondissements of Pont 1' Eve( jue and Lisieux, almost entirely included in these limits, present vast chalky plateaus cut by deep valleys, showing a clayey or argillaceous deposit overlying the rock. The second region where the limestone (great oolite, inferior oolite, marls, and sandstone) predominates, includes the arrondissement of Caen and a ]iortion of those of Falaise and Bayeux. All that portion of the Department of Calvados which comprises the division of Vire, the southern part of Bayeux, the western part of Falaise, and the southern part of Caen, under the name of Bocage, has a peculiar aspect. Its granites, gray and reddish in color, its schists, its arid plateaus scarred with great l)locks of rocks, its houses constructed of materials of somber color, all present a rather melancholy aspect. Climate. — Calvados, which is situated on the l)order of the sea and has no consid- erable elevations, enjoys a nuich milder climate than its geographical situation would warrant. It is part of the belt where the Seine or Parisian climate predominates, thus named because it is peculiar to the basin of the Seine, and particularly to Paris. In its general characteristics this climate is mild, but at the same time humid and variable. In sj)ite of its low elevation and the frequent rains (one hundred and thirty-five (lays in a year) maintaining a chilly humid atmosphere, the climate of Calvados is very healthy, this department occupying the first rank in the relative longevity in France. The western part of the canton of Tsigny and the country situated at the mouth of the Sougnes and the Dives are less favored than the rest of the department. Bui. 71. Bureau of Chemistry, U. S. Dept. Agr. Plate III. Types of Cider-apple Trees in Normandy. France. ^/^ 28 The spring here is cold and rainy, the fine season lasts for only a month and a half from June into August. The annual mean temperature of Caen is a little higher than that of Paris, which is 10.6° C. The winter on an average is less cold than at Paris and the sunmier is ■not so warm. The predominating winds come from the west, north, and south. Violent storms often desolate the fields at the time of the ei^uinoxes. It rains oftener on the border than in the interior of the department. The rainfall is 74 cm. (29 inches) annually, being not quite etjual to the average in France, which is 77 cm. (30 inches). « A student of the geolog}^ of Nonnand}-, M. de Ctiumont, has pub- lished a remarkable statement in regard to the influence of the soil upon the quality of these ciders in which he sa3's: The quality of the ciders produced upon different soils shows very great differences, as those who use these ciders have been able to determine by comparing the prod- ucts of several cantons. These ciders, like wines, are more or less strong, and one is able to preserve them a greater or less time, according to the soil upon A\hich they were produced. If my observations have not deceived me, the presence of fragments of quartz and silicious (flint) rocks in the earth, is very favorable to the production of a good cider, that which above all has the most agreeable taste. Therefore, the Ijest cider prod- ucts in the arrondissements of Bayeux and of Caen are produced upon the mottled sandstone soils, earths covered very often with a great quantity of alluvium, with nodules of quartz and flint, or upon the hard limestones and lower oolite soils of a limestone and clayey character, which are covered up themselves with fragments of quartz and flint, as near Cartigny and the environs of Tsigny, and several communes of the cantons of Crevise, Littry, etc. In the arrondissements of Lisieux and Pont I'Eveque the best productions are taken from the chalk formations covered with an argillaceous formation carrying flint nodules in quantity. * * * These numerous observations lead us also to think that the apples harvested from a soil where lime is in excess, as upon the great oolite plains of Caen and of Falai.se, are less sugary than these others which grow upon an argillaceous soil. The cider produced from fruits grown upon our limestone plains becomes acid at an earlier stage, and it is very inferior in quality to that made at Bessin and the regions of the chalk substrata like Lisieux and Pont I'Eveque. I have made these observations not only in Calvados, but in the commune of Orne, where the regions vary equally as much in their geologic characters as in Calvados. « At Danestal, in Calvados, some daj^s were spent during November observing- the work of the small landed proprietors or peasants (Plate IV), and as this coimtr}- is t,ypical of the very best cider-producing area of France, the soil was carefully examined and its agricultural value ascertained. The soil on warm southern and southeastern slopes was very rich in the first reaches above the streams, but grew thinner very markedly toward the summits of the low hills. The best soil was a rich brown loam, showing abundant nodules of flint, and at a depth of 12 inches or more a grayish sand became predominant. Along the upper slopes a gray soft sandstone showed occasionally and seemed to dip down into the hills as though erosion had carried away what was once the « Translation from manuscript notes furnished by IM. Truelle. 24 hioher levels. The abundance of Hint nodules was everywhere a char- acteristic of the best lands. The best exposures were generallv planted in fruit trees and covered with heavy sod, most of the orchards being used as pastures. There was very little land under cultivation in crops. The cold slopes were mostly thin lands and often seepy, and where set in orchards were decidedly inferior to southern slopes. The uplands varied in value from 5<)0 to 1,200 francs per hectare ($40 to $1100 per acre), and the richest valley lands were held at 4,000 to 5,000 francs per hectare (1300 to $400 per acre). These values lead one to wonder how anyone could carry on such apparently careless culture and con- tinue to hold lands of such value. The German Cider Districts. In Germany as in France most of my time was given to specific investigations at those places which otfered the greatest opportunity for practical and scientific work, viz, at centers where the bulk of the cider is made; hence, the Wiirtemberg cider districts of Germany were not inspected, but the related districts of Switzerland and a part of southern and central Bavaria were ol)served. In these nothing worthy of special mention was found. Everywhere, however, the wonderful opportunities for development which would be seized upon by a more versatile people were conspicuous. At Frankfort-on-the-Main is found the center of the German cider industry. Here two firms alone were making over 1,300,000 gallons of cider annuall}^; and from Frankfort to Wiesbaden, along the slopes of the Taunus Mountains, one finds a continuous apple country with numerous small establishments for the manufacture of cider. The industry here overlaps into the wine country, or Ilhinegau proper, and extends even down to Schierstein, almost in sight of the world- famous Johannisburg wine district. But nowhere in Germany was found any area so peculiarly and distinctively a cider-producing coun- try as in Calvados, France. In German}^ the tendency seems to be away from the small peasant proprietor, and toward a factory system founded upon the very best and latest investigations of modern science, while in France this is not nearly so much the case. Possibly this fact, coupled with the well- known orderly and methodical habits of the German, may account for the fact previously stated in this report, that in Germany standards of quality are better recognized than in any other European country. As already noted, the German considers his product a wine, calls it so. and makes it by certain definite methods. The only apple-growing districts of Germany Avhich were examined were (1) the Taunus country in Prussia, stretching from Frankfort to Wiesbaden, and (2) the Rhinegau, which extends from below Wiesba- den to where the Rhine })reaks throuo-h the Niederwald below Riide- Bui, 71, Bureau of Chemistry, U S. Dept. Agr. Plate IV. Homes of Peasant Cider Makers in Normandy. France. 25 sheini. The Rhinejiftiu is not, properly spoakiiiii:, an apjjlc-frrowing- district, as here the g-rape overtops evervthino- in importance, but 1 found the cider industry well represented as far down the Rhine as Schierstein. The Taunus reoion is said by well-posted German students to be the best apple district in German3\ This district is not large, and comprises the western and southwestern slopes of the Taunus ^loun- tains. The orchards occur occasionally even down on the more level drift soils of the floor of the Rhine Valley; but usually the flat lands along the Rhine are occupied t)v cultivated farm crops, or where spui's of the foothills jut down into the Rhine plain they are oftencr occupied by vineyards than by orchards. The Taunus Moiuitains are not high, being about 1.300 or l^-lOO feet at Cronberg, and nowhere in this district do they rise above 2,000 feet. They slope graduall}" to the foothills and alluvial lands of the lower levels, presenting gentle grassy slopes and rolling uplands, generally eas}" to till and presenting no difficulties whatever for orcharding. The Rhine plain has here an elevation averaging about 300 feet above sea level. The higher levels of the Taunus show some outcrops of shales, over- h^ing igneous rocks of great variety, as gneiss, mica,- and feldspathic schists. The slopes occupied ])y the great orchards show a clayey soil, with much gravel intermingled, and, while not very rich, good care has kept it well supplied with humus and in good condition. The trees are of great size and vigor, and so far as observed, the fruit crrowers do not have to contend with the numerous insect and fungous troubles met in this country. The exposure is ideal for fruit growing in a country so far north; and. in general characteristics, this would be considered a tvpically fine orchard vsection. The Taunus country has climatic and soil conditions strikingly dif- ferent from those found in the French orchard country. This German district has a continental climate more like that found in America than that of France, and the whole environment is essentially like that of many American orchard regions. The character of the apples grown and their chemical composition are much closer to American t3"pes than to French. Manj' varieties are grown for culinary and dessert uses, and the low-grade fruit, along with some distinctly cider apples, is employed for cider-making purposes. In some places the orchards cover the hillsides, all types, ages, and qualities intermingled without much system. And here was seen for the first time the giant trees of P(/nis {Sorhi/.s) dnnitxtlca, whose fruits are used to mix with ordinary apples to produce the highest grades of cider. The lowland orchards did not have the vigorous appearance of those on higher levels, and often those in flat fields were heavily cropped under the trees, while the uplands were usually in grass. 26 That the quality of the German fruit is quite inferior for cider makincr to that of the best French fruit seems to be evident from chemical data g-iven in this report. It does not appear, however, that the studies of the fruit and the ciders made therefrom in certain districts have been carried out with as much care, from the labora- torj^ point of view, in Germany as in France, thouo^h German factory work seemed quite superior, as remarked above. There are certainly some very important points awaiting- investigation in regard to the effect of soil and climate upon the composition of apples and the result- ant qualities of ciders made therefrom. A comparative study of this sort on the German and French fruit would be interesting- and yield data of much practical importance. The English Cider Districts. The wonderful variety of geological formations occurring in such a small country as England confuses the stranger and renders observa- tions somewhat difficult. However, after traveling twice over the chief fruit sections of the country, the writer was able to discrim- inate somewhat as to the character of the orchard lands. The l)est development of orcharding observed was in Hereford- shire, Worcestershire, and Gloucestershire. The second best was in Somersetshire, though Devonshire which has a rather ])etter reputation than Somersetshire, was not visited. The general statement current in England is that the orchard counties are Herefordshire, Devon- shire, and Somersetshire, in the order named, but certainl}^ portions of Worcestershire and Gloucestershire should not be omitted from this category. In the excellent monograph of Dr. Henry Graves Bull, of Hereford- shire, on the Vintage Fruits,'^' he points out that in the first two counties named the good orchard lands are situated on like geological formations, viz, the old red sandstone. In Herefordshire the great vigor and f ruitfulness of the old orchards, on the fine rolling red lands, were specially noticeable, and the ciders made, especially at Hereford and at Hellens, near Dymock, were as tine as one often finds. Equal praise can, however, be given to the fine cider and perry made on the estate of Lord Sudley, near Winchecombe, Gloucestershire. But as soon as one mounts the Cotswolds he is aware that he is off the fruit lands. The apple growing seen in Somersetshire did not impress one favora- bly, and the soil did not seem to produce anything like the fine trees observed in the more northern counties mentioned. It was rare, indeed, that the orchard plantings seemed to be placed with care, and the impression made was that as an industry there was no modern devel- opment perceptible. As to orchard growing in England, the best tech- «A popular treatise based on Dr. Bull's great monograph, The Herefordshire Pomona. 27 nical work seen was that of the Toddington Orchard Company at Lord Sudley's place in Gloucestershire. Though there is much small fruit g-rown in K<^ut, one of the famous fruit counties of England, very few orchards of any note were found, and cider making is almost unknown. . There are, however, in the county good, strong, retentive loam soils, which carry abundance of flint nodules and overlie chalk formations, as in the cider districts of France. In England, as in Germany, very little attention has been given to the development of cider fruits as such, though in the former there are numerous good varieties to start from. The ])ulk of the product is made from the refuse of those varieties Avhich are grown for table and culinary uses. Yet distinctly cider apples are constanth' met with, and a few cider varieties have recently been imported from Normandy and are gaining in favor. No definite statistics are available as to the production of cidei- in England, l)ut Hon. C. AV. Radcliffe Cooke, in a recent article in the Nineteenth Century, draws the conclusion that the total annual prod- uct is not less than 100.000,000 gallons, having a maximum value of £3,000,000 sterling, (nearly $15,000,000)." CIDER APPLES. It is doubtless correct to say that there are few distinctly cider fruits grown in the United States at the present time. Formerlv this class of apples received more attention. Scions of European cider apples have ])een distril)uted of late years by the L'. S. Depart- ment of Agriculture, l)ut there are as j^et no orchards of apples or pears grown .distinctly for the manufacture of cider and perry known to the writer. In this regard the United States is at present in pretty nuich the same category as Germany. England is somewhat better oH', as one tinds there a few distinctly cider ap})les and i)erry pears in cultivation. France has, however, made long strides in this direction, as already noted. It is of prime importance to consider heiv what constitutes a cider fruit, and compare the products of several foreign countries w itli that of our own in this regard. There can be no question that the making of cider by the landed proprietors and peasants of P^-ance for many centuries from the seed- lino-s of Normandv. Brittanv. and Picardv mav be credited with tix- ing the attention of the more critical students and cultivators of recent years upon the best characteristics of the French cider fruits. In these ancient seedling orchards and their descendants have been deter- mined empirically the qualities which distinguish cider fruits (pommes a cidre) from table fruits (pommes a couteau) in France. (I Nineteenth Century, August, 1901, p. 276. 2S The work of the past thirty j^ears in France has been directed to the task of sifting- from these hundreds of seedlino-s (ponimes sauvage) those which best embody the desirable chemical constituents and which also show the other desirable characteristics of hardiness, vigor, pro- ductiveness, proper season of blooming and maturity of fruit, adapt- ability to certain soils, keeping qualities, etc. Among those who have led in the critical studv of cider fruits of France might be named Messrs. Hauchecorne, de Boutteville, Truelle, Lechartier, Herissant, Power, Andouai'd, Hubert, Beaurepaire, Sequin, and man}' others. A greater amount of work by far has been devoted to a study of the chemical composition of varieties, their description, classitication, etc., than to strictly experimental researches upon cider- making problems proper. It seems that little is now to be desired, so far as relates to analyses, classification of varieties, etc., but that much is wanting in the French work relating to real studies of soil and cli- matic influences and the practical problems of handling and working up the crop. Much has, it is true, been written on these problems, but there is a dearth of facts in such literature as is obtainable. The French cultivators have now a great number of what appear to be the best cider fruits in the world read}' at their hands, and they owe a great debt of gratitude to the unselfish work of the gentlemen named above for their often unremunerated critical studies, made at the expense of much time and labor. In this regard M. Truelle, a pharmacist, of Trouville, Calvados, is perhaps the most shining- example. There have been no such elaborate studies made of German cider fruits, nor of the low grades of commercial fruits so largeh^ used in cider making in that countrv. although chemical data on the German fruits is not wanting. Professor Kulisch has made at the Ro^-al School of Geisenheim somewhat extensive chemical examinations of varieties of apples. In England until quite recently no critical study of cider fruits was known, but now, under the auspices of the Bath and West Societ}^ supplemented by a royal grant in aid, Mr. F. J. Lloyd, of London, is making chemical studies which have already advanced to a stage where they furnish very useful data for comparison. IMPORTANT CHARACTERISTICS OF CIDER APPLES. The French students of this subject and also the French manufac- turers of cider rank the value of varieties in accordance with their content of (1) sugar, (2) tannin, (3) mucilage, and (4) acid. They also insist upon the fruits being of fine flavor and fragrant. To a stranger the most striking characteristic of man}' of the French varieties is their delicate, bitter-sweet flavor, and the powerful and peculiar odor which they exhale when lying in bulk ripening. 29 The writer can not refrain from observing tiiat apparently the French attach entireh' too slight importance to the acid content of cider fruits. French apple must sometimes turns black as ink in the presence of air because of rapid oxidation of the tannin; yet it is easily shown that a higher acid content will prevent this. From some state- ments made it would appear that the}' consider i».l to <>.2 per cent of acid sufficient. The Germans rank the chemical constituents in importance as fol- lows: (1) sugar. (2) acids, and (3) tannin. They pay practicallv no attention to determining mucilaginous substances. Their ai)ples are so difierent in character (as will be seen in later discussion) that these constituent elements may not be strongly developed in them. They also claim that nitrogenous and mineral compounds are important as nourishment for the veast organisms. The acid content is considered important in German}-, and at Geisenheim the i)ercentage of acid demanded is 0.6 to 0.8 per cent. While they insist upon the import- ance of tannin, thev do not rate it so highly as the French. No English student of the subject appears to have discussed these points from an original standpoint. However. Thomas Andrew Knight was the first to call attention to the value of the densimeter as an instrument to test the quality of must. In the United States we have no technical literature of any moment covering this subject. It appears that Americans have proceeded on the idea that the sugars are the only substance of prime importance in an apple must. Tannin appears to l)e regarded as ol)jectional»le. Acid is apparently regarded as an element which it is necessary to eliminate as far as possible. The character of our fruits may have had something to do with this, but it is rare that our fruits show too nuu'h acid, and it is more to be noted that they seldom or never show enough of the ver}' important element, tannin. Sugar content of the fruit.— Duv'xw^ the process of fermentation cane sugar and possibly some of the pectose bodies are converted into fermentable sugars, and practically the total sugar content of the apple is thus rendered subject to the breaking down process called fermen- tation. Pasteur's statement of the products resulting from the fer- mentation of fruit sugars per 100 parts is as follows: Per cent. Carbon tlioxid gas (CO,) ■*t>- 67 Alcohol : - -t^- ■*<' Glycerin ^--^ Succinic acid ^- • -^^ Matter consumed l)y ferment organisms 1- 03 While this statement is now disputed in some particulars, it is used here to indicate the probable results which may be expected from complete fermentation of the sugar content of any fruit juice. It is, then, from the sugars that all the alcohol is derived, and also the car .30 bon dioxid ^as, the first being that which gives the strength to the beverage, the second that which renders it sparkling and piquant if retained in the liquor. The glycerin helps to give body and flavor to the liquor. It is derived partly from the alcohol and doubtless in part from the organic acids present in the must. Tannin, or tminic acid, in the f rait. — This is the substance so readily recognized in unripe persimmons or in the bark tissues of oak trees. In fruits it tends to give a bitter taste and to pucker the mucoUs mem- branes of mouth and throat. It is undoulitedly the relatively large amount of this constituent which gives to the bitter-sweet apples of France their peculiar character. This element is of great importance in the composition of any fruit for wine and cider making purposes, because of its action in coagulating albuminous elements in the must, thereby assisting to clarify the liquor, its wholesomeness to the system, and its efl'ect in conserving a c'ertain portion of the sugar from too rapid fermentation, thus adding very materially to the soundness and keeping qualities of the beverage. The writer is inclined to agree with the French that this element is more important than the acid. Three to five parts per 1,000 of tannin (0.3 to 0.5 per cent) is a sufficient quantit3% American fruits fall far below this standard. Acids in the fruit. — These exist in the apple and pear chiefly as malic acid, but possibly also as tartaric to a small extent. Their importance in a cider fruit is very considerable. If acid is not present in sufficient quantity, the oxidation of the tannin will be so rapid as to turn the must black, or blackening may even occur in the finished cider. Also the refreshing quality of a cider as a summer beverage is largely due to its acid content. American apples usuall}' contain sufficient acid. Mucilage in fruit. — The practice of determining this substance as mucilage in apple must seems only to be followed b}^ the French chem- ists. Whether their determinations are comparable with the deter- minations of pectin b}' other chemists can not ])e here stated. These substances, give body to the cider and are important constituents of good cider fruits. COMPARISON OF CIDER APPLES. FRENCH STANDARDS. It is a matter of unquestionable importance to compare the fruits of the three prominent European cider-producing countries with one another and with our home fruits as to chemical composition. The French students "of the subject have attempted to set standards by which varieties should be selected. The following is quoted from M. Hauchecorne (''Le Cidre" p. 9), in which he gives what he has deter- mined to be an average composition based upon analyses of manj'^ French varieties: 31 Specific gravity 1 . 067 to 1. 080 Water per cent . . 80 Sugar ( fermentable ) do 17.8 Tannic acid do 5 Mucilage or pectoSe do 1. 2 Free acids (organic) calculated as sulphuric do. ... . 107 Earthy matters, etc '. df) 893 Total erry pears, for a fine and delicate beverage, should siiow a medium density, i. e., ranging from 1.057 to 1.064, and not exceeding 1.069; sugar content, medium, 12.5 to 14.5; tannin (maximum), 0.3 per cent; flavor, sweet, slightly bitter. The distinctive qualities should be a clearly defined, delicate aroma and a sugary flavor. 2. Varieties designed for ihampagne should be as above except that there should be absolutely no bitter taste. 3. Varieties destined to make a strong alcoholic beverage should show density, 1.065 and above; sugar, 14.3 per cent and above; tannin (minimum), 0.2 per cent and above, the more the better; flavor, unimportant, except that it must not be acid; strong and penetrating aroma; the controlling qualities being richness in sugar and tanniu. 82 4. Varieties destined for making distilled liquor should show a mininuini density of 1.070 and 15.5 ]jer cent of sugar, the richer the better. The other characters noted do not play an important role in this category. « If the den.sity and sugar content given in the first category are only medium for French fruits, in what ciitegory can one place German and many xVmerican and English cider fruits? The French have adopted a high standard in quality of fruit, and the chemical analyses reported by the numerous investigators bear them out in this position. Do these qualities result from peculiarities of soil, or have these century- old seedling races of French ap^^les acquired certain characteristics which can now be perpetuated in other land,- b}' ordinary j^ropagation? Can their seedlings, when grown in other countries, become the founda- tion stock of seedling races of apples which will show such wonderful richness in saccharine matter and tannin as their parent stocks? After thirty years of study along what these French investigators seem to consider preliminary lines, but which has yielded already the best technical literature in the world on the subject, the Association Franyaise Pomologique appointed a commission, composed of its best scholars and cultivators, to undertake a critical study of all the data, and also to conduct an original investigation of all promising French cider fruits with a view to correcting the nomenclature and establish- ing a standard list with authentic information as to quality and char- acter of fruit and character of plant, so that cultivators shall have a definite guide to aid them in making plantings. The fruit of each variety selected for the standard list is reproduced in color for the bulletin of the association and uiodeled for the permanent collection. After four years of study this commission has made considerable prog- ress. On its organization at Mans in ISlKs, the commission adopted the following outline of points on which the varieties of fruits should be judged: (1) Vigor of plant. (2) Natural resistance of same t>> fungous and insect attack. (3) Fertility (productiveness). (4) Quality, based upon the richness of tlic fruits in useful substances, but,al>()ve all, upon its known jiractical value as a cider fruit. '' Out of the immense number of French cider fruits the commission decided that only 40 or 50 varieties of apples should be admitted to the permanent list, and 8 or 10 of pears, and that each subsequent year not over 5 or 6 varieties might be added to the list, and that these must be voted upon for three successive years before they could ])e considered as finally accepted. Up to the present the records onl}^ show 86 varieties of apples definitely admitted, and of these but 12 have yet been voted for reproduction by colored plates and models. « Condensed free translation from Proceedings of International Congress, Paris, 1900, pp. 48-50. ^Bul. de I'Ass. Fr. Pom., Hi: ;;5. 33 These 12 varieties represent perhaps the best known and most care- fully studied French cider apples. The chemical data which appear in the accompanying table have been collected from the t)ulletin of the Association Franyaise Pomolog-ique. For most of these varieties a very considerable number of analyses are reported. Of these analyses the maximum and minimum deter- mination for eacii sul)stance are g'iven, and then the mean of all the determinations of each substance. A\'hile there are some very striking differences between the determinations given in a number of instances, yet it is perhaps fair to say that the mean results ought to be reliable for the average composition of these varieties. Certainly no sm-li elaborate data are at hand for the compilation of average composition of cider fruits of any other country. To one familiar only with our best Amerii-an varieties it is ciuite startling to note specitic gravity determinations reading as high as 1.133 and total sugar 24.31, as shown by Saint-Laurent, and 1.134 specific gravity, sugar 20.35, as shown b\^ Bramtot. Rousse falls but little below these. The above figures are, it is true, the maximum given, bu,t the means for sugar of these varieties— K?. 51, 19.05, and 17.19 grams per 100 cc of must — are so far above the averages of American or German fruits that the comparison is ecjually striking. The mean acid content is very low, falling far below the German theoretical mean desired. In tannin these varieties exceed by tar those of other countries, but yet rarely show a quantity sensibly above the theoretical minimum of 0.2 per cent demanded by the French stand- ard, and only in one case, Bramtot, reaching a mean which approxi- mates the theoretical maximum (luantity desired under the French standard. The varieties in the following table are arranged in accordance with the French seasons for cider apples: Table I. — Maximum, minimum., and mean comiwsition of 12 French cider apples, specially selected as standard sorts by the Association Frani^aise Pomologique.

In addition to the list of 12 varieties shown in this table there are 24 other varieties of apples alread}^ admitted to the standard list by the commission of the Association Franyaise Pomoloo-iqne, and 7 cider pears are provisionally admitted. Strange as it may seem, 2 of the varieties of apples admitted to the list (Frequin-Lacaille and Muscadet de la Sarthe) could not be identified in the present state of the nomen- clature so as to g-ive the chemical composition of the must. Of the pears admitted provisionally the anal3^sis of but 4 could be ascertained with certainty from the literature examined. The chemical composition of varieties given in the subjoined Table II is largely taken from Volume II of Mr. G. Power's exhaustive treatise on the "Best cider fruits."' In every case where more than one analysis is noted the average is given from Mr. Power's work. Where but one analysis is noted, the figures are in every case except one quoted from Messrs. Sequin and Pailheret, of the National School of Agriculture at liennes. One analysis — that of the variety Havar- dais — is quoted from the work done by Mr. Pic at the Practical School of Agriculture of the Three Crosses near Rennes. These two schools just outside of Rennes are now doing an immense amount of work on the investigation of cider fruits. When possible, the average of analyses covering a period of years is quoted. 35 Table II. — Composition of French cider fruits admitted to the provisional list of the Asso- ciation Francaise Pomologique .

The GermaiLS do not appear to have attempted a study of varieties of apples and pears for cider purposes in anything- like the compre- hensive manner of the French students. It seems that the German cultivators have worked on other lines than those of the French. To an American it appears that ordinary orcharding in Germany i.>^ about as far advanced as it wa.'^ in the United States twenty or thirty years ago, before the wonderful development of commercial orcharding in this country. There are many good varieties of grafted fruit, and these are cultivated at times in considerable areas, but neither orchard- ing for table fruits nor for cider fruits is well developed in Germany, except where the dessert fruits are grown in what we would call gar- den culture ou walls, trellises, etc. The German cider fruits, so far as they can be ditierentiated from dessert fruits, are occasional seedlings of no peculiar character or special value. There are certainly no varieties to compare with the special varieties recorded in the French literature and shown at the 36 French pomological congresses. In fact, the Germans use their chance seedlings and the refuse of their table fruits for cider about as we do in America. But the great manufacturing establishments draw sup- plies by rail from Russia, Austria, and Switzerland in large quantities, and much of this f i-uit ma}' l)e of a more special grade for cider than that seen growing in the Taunus and Rhinegau regions of German^^ These establishments also draw supplies from western France when- ever crop failures in nearer regions render this necessary. The chemical data on German varieties a^e also meager, or at least so scattered that nothing approaching full data could l)e collected dur- ing the time of the visit. Later correspondence with very reliable book dealers has failed to develop this information as fully as could be desired. There are 53 ditferent sorts or varieties of German-grown apples mentioned by Dr. Cluss" in his recent work on cider making in Ger- many. Of these 29 were anah'zed by Professor Kulisch at the Royal School of Pomology at Geisenheim. Out of 17 varieties anal3'zed b}' Professor Behrend at Hohenheiiu, Wiirtemberg, i;> seem to be sorts not included among those examined at Geisenheim. These doubtless fairly represent Wiirtemberg cider fruits. Dr. Kramer's anah'ses of cider fruits at Steiermark, ([uoted by Dr. Chiss, give 11 out of 15 varieties reported upon, Avhicli are not included in either of the above- cited lists. Thus we have 53 varieties represented in the following tables, which, from the German literature consulted, seem fairly to represent the range of German apples in the best cider districts. Director Goethe, of the Lehranstalt fiir Obst-und Weinbau at Gei- senheim, .says the Schafnase and Rhine Bohna])fel in Nassau, the White and Red Treierischer wine apples in the Rhine pro\'inces, and the Luiken and little Langsteil in Wiirtemberg are the best six Ger- man cider apples.

It is known popularly as the Speierling, Speierlingbaum, Speierling crab, etc., and is a native forest tree of central Europe, but was not observed in France. Whether it has been always intentionally planted in the orchards of the Taunus or is partly wild is doubtful, for it is not usually seen in the regular rows, l^ut in odd nooks here and th^re. On the borders of mountain ravines it is a most beautiful and luxuriant tree 20 to 4() feet high and loaded in the fall with small pyriform fruits aljout half the size of Seckel pears. These become yellowish in color and fall to the ground late in autumn, where, after some days, one can pick them up and eat them with considerable relish; but if plucked from the tree or eaten l)efore they become mellow, the result on the mucous mem- branes is about the same as that of biting a green persimmon. This fruit is gathered in quantity just at maturity and before ripen- ing begins, and it is then used to fortify the best grades of ciders. Either the fruits are crushed with the apples in certain proportions or are ground separately and the must added to apple must in detinite proportions. The latter is believed to be the better mode of l)lending, and it is the one pursued in the large establishments of Freyeisen Brothers at Frankfort. They had great casks of this must in reserve in a very cool cellar more than 50 feet below the surface of the earth, which they were using to blend with the finest apple juice to make the high-grade '■■ Speierling apfel wein." As nearl}" as could be deter- mined about 1 part in 20 of this must from Sorbus fruits was added to the apple juice. It seems astonishing, considering the great importance of this fruit, that no recent writer should have treated it in the German literature and that not a single analysis of the fruit or juice could be found. About a century ago J. L. Grist wrote quite comprehensively of its use in making wine and in blending with apple juice, but gave no chemical data. It is supposedly used at present to tone up German ciders in tannin, thus adding piquancy and flavor to the product. The sugar content of the fruit could not ))e ascertained. Director Goethe, of Geisenheim, kindly furnished an article written bv G. W. Eiche- nauer, of Cronberg, Taunus, in which he discusses this fruit from a gardener's standpoint, but does not give critical data on its composition. He states that cider made by properly blending it with ordinary stock is worth twice as much as it would have l)een otherwise and will keep much longer. If it is the tannin principle alone which makes this fruit so valuable, certainly it is time we in the United States looked more to the selection of varieties rich in this substance or resorted to wild fruits, such as the native persimmon, JJyoxpyrus inrginiana, to obtain it. 39 ENGLISH SIASDARnS. An}' attempt to stud}- the cider apples of England, or tal)le varieties for that matter, is greatl}- complicated b}^ the endless maze of names of similar orthography which have been given to apples. ))oth cider and table varieties, and bv the fact that there is no reeoo-nized authority on the nomenclature of orchard fruits in the entire countrv. Every local connnunity appears to delight in applying names of its own choosing to the fruits grown, and there seems to be no general dis- position to reduce the nomenclature to a system under some comj)etent authorit}', as for instance, a national committee on pomological nomen- clature. Of recent writers on pomology in its broader sense, there are very few, but the older works, as those of Knight. Marshall, Evelyn, and others are classics of their time. The best modern treatment of the subject of pomology, in a some- what limited sense, which was secured is The Apple and Pear as Vin- tage Fruits, by Robert Hogg, LL. D., and Henry Graves Bull, M. D., a charmingly prepared general dissertation upon the subject of cider and perry making, with critical notes and cuts showing many varieties of cider fruits. In the way of recent litei-atiire, the Bath and West Society deserves great praise for the efforts it is making to develop a reliable literature on modern cider making. In fact, it is putting forth an effort to arouse the popular interest so necessarv to the future progress in pomology as an art. and more specilically as it relates to cider making as an important industry. However, in this literature it does not appear that a successful attempt has been made to establish a standard toward which the grow- ers of cider fruits should direct their attention. The nearest approach to a standard as to quality of cider fruits which was found in the works mentioned is in tlu^ report of the committee of the AA'oolhope Clul), which visited the congress of the pomological societies of France, at Rouen, in October. ISS-t. ^^'hen this conunittee determined to select a set of French varieties of apples for introduction into Here fordshire thev laid down the following rules:" (1) The fruit must possess the very best quality of juice. (2) The trees must be hardy, vigorous, and fertile. (3) They must bloom at varying intervals. (4) The fruit must attain maturity in late autumn or winter. (5) The varieties must have obtained the highest reputation in the Norman orchards. The fact that these gentlemen from Herefordshire recognized the importance of securing some of the best Norman varieties of cider apples for introduction into England indicates that some of the best English growers are alive to the importance of producing fruit of high qualit}' for the upbuilding of the cider industry. But such apples are alreadv verv common in England. The oldest English writers tell « Hogg and Bull, Vintage Fruits, p. 88. 40 us of fruits 3'ieldino- must of 1.001 specific gTavitv, which, if correct, is hardly surpassed in our da}' in any countr}'. There is a large group of varieties of apples cultivated in P^ngland chietiy for cider, the names of which are made up of some P^nglish word prefixed to the word Norman or Jersey, as C'herry Norman, Broad-leaf Norman. Chisel Jersey, Red Jersey, etc. These apples all possess the peculiar bitter-sweet taste which characterizes so distinctly many of the most famous French cider apples. An interesting ques- tion arises in this connection as to whether these apples are ancient im])ortations from Normandy and the Channel Islands. In the work on Vintage Fruits, quoted alcove, the opinion is given that they are not. This is l)ased on comparisons made in 1884 at the congress of Rouen; which really prove nothing further than that they are not recent importations. It appears, after extensive comparisons, that this peculiar race of apples so common in Normand}- has had a common origin, either in England or in France, indications all pointing to the latter countrv. Interchanges between England and the mainland have been such for many centuries that the parent stocks of the present race of bitter-sweet apples in England may very easily have been derived from French sources. Then there is the other argument, that all the historically old English cider apples, like Foxwhelp and Red Streak, which go back some two centuries in the literature, give no hint, either in chemical composition or quality, of common origin with the bitter-sweet varieties of France. From what was seen of these fruits in England it appears that if seedlings had been fret^lv grown from them and well selected, as in France, England would to-day have as good a race of cider apples as France has. But are the bitter-sweets so essential^ This question is not settled. In Germany scarcely a trace of thiy peculiar qualitv was found in the cider fruits, ,yet they make most excellent cider in Germany. Also in Gloucestershire and Herefordshire, England, most excellent ciders were sampled, in whose makmg no particular attention was paid to the usmg of bitter-sweet fruit. The question is an important one, and, with a view of giving- it ample study, the writer has procured and is growing a collection of French and English cider apples representing the l)itter-sweet and other old types. It has been necessary to examine a consideral)le mass of data in the attempt to select a representative list of English cider fruits. ]\Ir, F. J. Lloyd has examined and reported upon such a large nuinl)er of varieties in his work for the Bath lyid West Society that it is possible to use ])ut a small fraction of his data. Hence an att«Miipt has been made to select a set of varieties whidi shall re])rcsent the old renowned cider fruits and the more recent sorts which are coming prominentl}^ into notice. Among the varieties selected, the Blenheim Orange, which is an old popular variety grown for general purposes, and used 41 as a cider fruit also, has been selected for special presentation. Fox- whelp is the oldest, historically, of famou.>< EnoHsh cidm- apples, and King-ston Black is a very prominent recent variety. The other.>^ rep- resent the English-grown bitter-sweet apples, and a number of them are given because of their present prominence. However, no variety known to be of recent French introduction IsuscmI in the table, though several of these recent introductions are now becj-innincf to ti^'ure in the English cider factories. The chem-ical data are taken wholly from Mr. F. J. Lloyd's analj'ses, published in the reports of the Bath and West Society. The writer has compiled from his data analyses covering as manj- years as c(ndd be obtained for each of those varieties selected to represent English cider fruit.

Early in the nineteenth century much interest was manifested in the United States in the culture of cider apples, and in the manufacture of this Ijeverage at a few points. Perhaps Newark, N. J., was one of the most noted centers of this infant industry. In New England, how- ever, the cider fruits were cultivated, and the Massachusetts Agricul- tural Society showed considerable interest in encouraging these effprts. From scraps of information and brief references, it also appears that Virginia planters were interested, and rated good cider highly. William Coxe was one of the first to write on this subject, so far as the early literature available shows. His treatise on Fruit Trees is dated 1S17, and in it he speaks of the high (juality of Hewes Virginia Crab and the Harrison apple for cider making. The latter is of New Jersey origin, and helped to make the quality of New Jersey ciders recognized in the early days of our histor}". Coxe also mentions the Newtown Pippin and Winesap, both well recognized to-day as yielding cide]* of high quality, but lacking in the element of tannin. The Hagloe Crab, an old Englisli cider crab, is constantly mentioned in the early literature, and the Vandevere is also spoken of as a cider fruit. ■ In the change of habits which came over our people about the mid- dle of the past century, cider gradually lost its place as a beverage, used alike by the well-to-do and the laboring classes, and the'art of making it seemed to fall into desuetude. The country people and a number of large commercial establishments have continued to make a beverage from apple must, but, in the main, it is very inferior in quality. Even the varieties of fruit best suited for making this bev- erage have almost been lost to our pomology, and later writers rarely mention them. Yet it can scarcely be contended that our people use less fermented beverages or less ardent spirits than formerlv. The early American writers of consequence are Coxe and Thatcher, and these gentlemen did little more than copy the best English and French writers of their time, w^eaving in some local experience. Of real technical studv there was none. The writings of Thomas Andrew Knight, and articles in Willich's Domestick Encyclopedia, furnished the basis of these early dissertations. Many of the principles laid down 1)}' these old writers contain the germ of the best practice of the present day. Strangely enough, the new encyclopedia of horticulture (Bailey's) does not contain the word cider as a subject. It has already been stated that we have not at present in the United States a distinct industry in the groAving of cider fruits. Yet it is true that some of our crab apples, and some varieties of apples also, have been cultivated to a limited extent for cider and are considered valuable for this purpose, but it is seldom that they are grown to any laroe extent. 43 So far as the Avritor ha.s learned there is no teehnical literature deal- ing- especially Avitli the chemistry of American api)les. cither for cider production or the manufacture of other products. Hence, at present it is not possible even to sugg-est a standard composition for American fruits used in making cider. Even partial analyses of the old fruits mentioned above could not be found, save of Hewes crab. Such anal- 3^ses as have been made, up to a very recent date, are fragmentary and incompl(>te, and little attempt has been made to collect them. In 188G Mr. Edgar Richards, then an assistant chemist of the United Stiites Department of Agriculture, made analyses of the whok^ fruits of 16 varieties of apples, and the results of his analyses are given l)elow, so far as they concern this inquiry. These results can not be incorpo- rated in the tables of average composition of must from American apples because the fruit and not the expressed juice was analyzed: Table VIL- - Analyses of nhole fruits of apples by Edgar Richards, Dlrlsioti if Chemistry, U. >S.

''Calculated at Blacksburg, Va. The average sugar content in 100 cc of apple must for the 10 vari- eties given, as shown l)v Browne's table, is 11.94 grams reducing sugars, which for practical purposes may be read per cent. This is a low sugar content e\'en compared with German averages. The average acid, 0.62 grams in 100 cc of must, is high. From must of this aver- age composition one might expect to produce a cider of 5 per cent alcohol, with still a little sugar left unfermented. With such must undiluted, there is no reason to say that a cider of proper strength can not be produced. In the department of horticulture of the Virginia Agricultural Experiment Station the writer has for the past fourteen years been bringing together a large collection of pome fruit trees, more espe- cialh" of appks. This collection now contains 375 varieties of apples, including cra})s, collected from various portions of America and Europe. Many of these are now coming into full bearing, and Prof. li. J. Davidson, chemist of the station, has begun an exhaustive investigation of the chemical composition of the fruits. This inves- tigation is not undertaken solely with a view to studying cider making, but for the general purpose of accumulating scientitic data for our studies of these fruits in all lines as commercial fruits and as raw 45 material for the nuinufucture of various products. The following tabular statement furnished by Professor Davidson is useful here for the further consideration of American standards and for comparison of foreign and American v^arieties: Table IX. — Atudyses of apple mmt bij li.

It is distinctly noticeable that the crabs show a better analysis as cider fruits than the apples. In this latter list, however, there are no dis- tinctly cider varieties. While there are a large number of these special sorts iu our plantations, none have yet fruited. A number of analyses of fruits from the station orchard were made at the Bureau of Chemistry, United States Department of Agriculture, and these are here in.serted, forming Table X. The averages of specitic gravity readings at the two places are remarkably close. l)ut in other points there are diU'erences to be accounted for, partially at least, by the fact that the varieties examined in the two laboratories were only in part the same. 46 Table X. — Analyses of apple must by J.

If quality in cider fruit is such a prime consideration, then any- thing which acts either to enhance or to deteriorate the same must receive attention. There is much discussion of this point going on in foreign journals, and the standard literature of this subject contains many notes thereon. The discussion hinges about certain principal questions, as: (1) What is the proper season to gather the fruit? (2) Shall it be hand picked or shaken? (8) Shall it be kept in piles out of doors on the ground? or (4) shall it be kept on raised temporary struc- tures, so as to protect the fruit entirel}^ from contact with the earth? or (5) should it be removed at as early a date as possible into storage buildings ? Because of the fact that general culture of orchards for dessert fruit has not reached that stage of development in Europe which it has in the United States, they seem not to have worked out a sj^stem of harvesting fruit at all comparable to ours, nor does it appear, that the harvesting and handling of cider fruits reijuire such a sj^stem. Yet there are some important considerations to be observed. The early fruit which is turned into cider is generally treated with very little consideration. It is allowed to fall to the ground from the effect of natural ripening, and is either worked up from time to time or allowed to lie until such a time as it is convenient to whip off that which still hangs on the trees, and all is then worked together. This gives an uneven condition of fruit, and produces a poor product, which is fermented rapidly and used for a cheap trade. Such fruit appears 47 to be handled in most countries just as we ordinarily handle our iMitire crop of cider apples in this country. The fruit lies in heaps on the earth, quite regardless of unclean conditions, and is then ground with- out regard to uniformity of ripeness or blending for quality. The following discussion relates to observations made on the main cider crop. The practice of diiferent countries varies much on some points and will be noticed separately so far as there is ground for so doing. Consideral)le importance is attached to observing the maturity of the fruit. The French especially argue that both the sugar content and the quality of the product are affected thereby. The first will doubt- less be readily admitted b}^ all, and the second in part, but further investigation is needed before all that is claimed can be admitted. While the fruit should certainl}^ be mature — that is, it should have reached the perfection of its growth — it should not be allowed to ripen and fall from the tree, as this will lead to ver}- irregular ripening and yield at no time a satisfactory amount of evenly ripened fruit in proper condition for grinding. ■ The French lay great stress upon gathering and ripening in bulk, as they claim in this manner to secure the most perfect development of the delicate aroma which is such a marked characteristic of the best Normandy varieties. Their method is generally to dislodge the fruit by shaking and by the use of poles at about the stage of maturity which in America we recognize as right for gathering and barreling. In many places this fruit is left in huge piles under the trees until late in the season, though this is not considered the best practice. The better method, which seems to be quite well observed by' larger growers, and especially by those concerns which manufacture large quantities of cider, is to bring the fruit quite promptly into the lofts over the cider mills. This was the onlv house-storage method observed in France. It is well to explain here that the small cider apples grown in France bear shaking and beating off far better than would the large apples in our country, and further, the orchards are almost invariably set in heavy sod, which is an advantage in this method of harvesting. Their apples are often very firm at maturity, and some of them have a tough texture which resists rough handling well. It was surprising to see how little inclined the fruit is to decay from the effect of bruises and other slight injuries. The storage lofts in France were ordinarily fitted with bins or par- titions for the separation of apples of various qualities, so that they could be properly blended m grinding. Here were seen great struc- tures 100 feet long or more and 30 or 40 feet wide piled with apples to a depth of 4 to 6 feet, and such a loft in late November filled with this ripening fruit is pervaded by an aroma sometimes quite oppres- 48 sive and not easily characterized. When the room is not too close the odor is decidedly pleasant. Some makei's are very careful to store the fruit only a foot or two deep, but this is the exception. The invariable custom, so far as observed, was to run the fruit by gravity from the loft storerooms into the grinders, whence the j)omace falls into vats before going to the presses. The fruit is ground from these upper-fioor storerooms as it ripens some \'arieties not coming to their best untd Januar}^ or February, In the peculiar climate of Nor- mandy and Brittan}^ there seems to be ver}^ little danger of the weather becoming sufficiently severe to harm the fruit materially. The growers of this fruit are very largely the small peasant pro- prietors and small tenants, with here and there a large estate. The small growers are referred to in French literature as "recoltants." Often these peasant proprietors make up their own fruit and that of neighbors; hence the cider houses of these small makers are very common in some parts. But there is a tendency to commercialize, and more and more the fruit goes to the large manufacturer. To these it is hauled in carts (PI. V, lig. 2) loose or in sacks, the latter being the most popular method. These sacks are hoisted to the upper floor of the factories and distributed to the proper storerooms. There is also in France anothei- class of cider makers, who buy the partly fermented juice from the small growers and blend and work it up to suit the trade they wish to supply. These are known as "commercants." They often make an excellent article, but they are also charged with a vast amount of trickery in the production of sophisticated goods. There is, in the great crop years, an extensive railway commerce in cider apples, both to local points and to the near or distant states. The shipments are made loose in what we call box cars, and also loose or in sacks on flat cars (PI, V, fig. 1). The method of ship])ing in sacks seems to be preferred in France and might well be copied in this country. The Germans appear to prefer handling the fruit loose. No railway commerce in cider apples was seen in England. In 1900 such an immense crop was harvested m Normandy that the local rail- ways were literally blocked with fruit, as is sometimes the case on American roads when great quantities of coal are carried. At the local factories visited in France great stress seems to be laid upon gathering the late fruit when perfectly dry and storing at once in the bins, where more or less of it lies luitil January and Februaiy. There appears to be very little tendency to decay. The cider maker judges the ripeness of the fruit, or its fitness for grinding, by pressing with the thumb until the juice exudes or by breaking the fruit in half and crushing one portion in his hand with a wringing motion. Great stress is laid upon grinding at the best period of ripeni^ss in order to secure all the juice possible by expressing. Cleanliness is the rule in the handling of fruit in France, yet some dirty bad work was seen, BliI, 71, Buipau of Chemistry, U. S. Dppt. Agr. f^LATE V.

In Germany there is, in the first place, much less specialization in the growing and handling of cider fruits, and there appears to be much less manufacturing of cider b}' small landed proprietors. Thci-c were, however, small makers everywhere, but they ordinarily i)urchased their fruit as miscellaneous stock from various sources, and paid no attention to storing and matui'ing the same by a delinite sy.stem. but ground it up as needed. The large factories, as J'ai- as observed, also handled the fruit, less carefully than in France. It was purchased in wagonloads and car- loads and dumped into great bins on the ground, covered or uncovered. While, on the whole, it w\as handled in a cleaidy manner, no attention seemed to be paid to keeping it dry, or to the fine points of lipening the fruit. At one large factory lOO.Ooo kilos (100 ton.s) of fruit arrived daily, mostly l)v carloads, and was dumped into a great open bin, where the fruit lay in the open from a few inches to several feet deep until wanted for grinding. As cider apples are an incidental and not a special croj) in (iermany. it will be understood that harvesting is largely a matter of convenience rather than system. The refuse of dessert fruit, together with the inferior varieties and purely cider fruits, are collected as suits the growers' convenience, and disposed of at the factories or manufactured at home if the grower is also a cider maker, Cidei- making in (ier- man}' shows a strong tendency toward the factory system, and the makers have the techni(iue of fermentation well worked out. but that they handle a fruit inferior to that of the French and with nuich less care is certainly true. In England the manufacture of cider is very largely in the hands of the farmers, though the factory idea is developing. One sees chiefly the same old customs of harvesting and handling the fruit that have prevailed for centuries. There is in general no attempt at storage. The low-grade fruit (refuse from what the English c-ill "pot fruit," i. e., dessert and cooking grades) is gathered in miscellaneous piles in the orchard, and either ground from these piles or drawn away and sold to the factories. At the best mills the fruit is graded somewhat, so as to properly blend the same at grinding, but even at these the fruit may be seen h'ing in heaps on the sod in the orchard or near-by lots until late in Noveml)er. This practice gives to this fruit a very decided earthy flavor and odor, and in some cases it is largely dam- aged b}" decay. At Butleigh Court the fruit is stored in a loft over the press-room, and is kept in clean, dry condition. A method advocated by some in England is to make temporary bins in the field by using hurdles for sides and bottom, the bottom piece being deviated somewhat from the ground and all lashed together as 17247— No. 71—03 4 50 shown in the illnstration (lig. 1). This temporary rack is matted on the bottom and sides with straw and the fruit is then poured in. Such an arrangement permits of holding- the fruit quite clean, and it can be covered with straw to protect from early freezes. '"if "n Fig. 1.— Bin made of hurdles for outdoor storage of apples, used in England. The English customs of handling fruit are in the main about the same as those in the United States. There is little or no shipping of cider fruit, such as there is in France. It may he proper to say here that the French s3^stem of sacking this fruit in the orchard for transporta- tion, either by wagon or rail, seems to be well worthy of adoption by us. CIDER-MAKING ESTABLISHMENTS. The present manufacture of cider in Europe embraces establish- ments ranging all the way from the most primitive farm affairs to the most elaborate modern factory. Primitive methods of manufacture play a very important part in the grand total of product, and the users of primitive apparatus in many cases make an article equal to the best product of modern factories. Notwithstanding the tendency evervwhere manifest toward the modern factory system, it seems that the cider industry is so peculiarlj'^ adapted to the farm that it .should be the effort of orchardists, or at least of small communities, to conduct this work at home, and by making superior cider, vinegar, etc., from unmerchantal)le fruits, secure to themselves the very satisfactory profits which accrue to such a business ritrhtlv conducted. 51 In starting- a cider -making- establishment there are several points of importance which should he more or less observed. These are: (1) Supply of fruit; (2) supph^ of pure water easily carried into the factory under some pressure; (3) the la}^ of the gfround in regard to drainage, and the l)uilding of cellars or basement rooms; {-t) conven- ience for disposal of product, proximity to i-ailroad station, etc. These conditions are of equal importance to the small maker and to the large factory. pri:mitive methods and ApruANrEs. Persons employing very old methods of manufacture were oljserved in each of the three countries visited, but particularly in France, where there is in common use the old "tour Ti auge" mills; in fact, a Fir;. 2. — The "tour a auge"' apple cnisher, Xonnandy, Fninoe. modification of them is in use in some of the large factories driven by steam power. This machine is also in use in England, but to a very limited extent. In Germany, ancient hand devices were in use. l)ut the '"tour" was not seen. This very ancient device for crushing* fruits before expressing the must is shown in the accompan^Mng illustration (fig. 2). It is constructed of stone or of wood or by putting on a heav}' layer of cement over an iron form. Necessarily the trough must be made of some materi-.d that will not be acted upon by the fruit juices. The plan of construction and the opeiation are very simple. The entire apparatus is ordinarily about 10 feet in diameter. The outer and inner walls (fig. 2, a^ a') are about 30 inches high, and inclose a circular trough (/>), in which the grinding or crushing is done. This trough usually narrows toward the bottom, being about 20 inches wide at the top and 11 inches at the bottom. The inner 52 wall is almost perpendicular; but the outer slopes decidedly toward the center of the trough, which varies in depth, luit 14 inches is the usual depth. Within the inner circle, or cistern (r), rises a vertical coUuun to a support above, and to this is attached the radial arms which carry the crushers (d). This inner space or cistern is some- times used as a receptacle for the fruit before grinding. The fruit falls l)y means of a chute from the storage loft into this cistern as desired, and from it is put into the grinding trough with a wooden shovel. The rollers or crushers are usually made of a lirm heavy wood with a somewhat corrugated surface. Rollers are also made of granite, but this makes them very heavy, and they are said to crush the seeds of the fruit, which is not desired. These huge wheels are about 3 feet in diameter, and about 6 inches to 9 inches on the faces. They are set so that the}' do not trail, thus covering all the bottom surface of the trough. A small device, not shown, follows after the crushers and scrapes the pomace and uncrushed fruit down into the bottom of the trough. "Tours" were seen with only one large Inroad-faced crusher, and with various other modifications, but the one tigured seems to be of the typical form. Where used in steam mills, thev are rigged with the crushers exactly opposite each other, on tixed radial Inars, and the perpendicular shaft is turned l\v a pinion wheel. In this manner the}" are driven at rather high speed, and are used principally to remix pomace with water for the second and third pressings. The "tour," as shown in the illustration, is typical of those used by the small peasant proprietors in France. It is worked by a horse which patiently plods around its limited circle, becoming so used to the work as to require no attention. In fact, he soon learns to forage on the fruit by twisting his neck so as to gather the pomace from the front crusher as it revolves. Hence he is not removed for feeding until the day's work is done. The fruit is thrown into the trough 2 to 3 inches deep and the horse is put in motion, and during the grinding, the attendant is bus}" with other duties, as fitting up the "cheese," bearing away the cider, etc. The fruit will be reduced to pulp ip twenty or thirty minutes, vary- ing with its texture. The attendant then turns on a scraper, attached at the rear of the rollers, which shoves the pomace into a heap at the side adjacent to the press. From here it is lifted with a wooden shovel to the press platform. The cheese is laid up very much as with us — • viz, wrapped in special cloths — each section or lozenge 4 to 5 inches deep. Instead of cloth, straw is often used to divide the mass of the cheese into layers. To put up a cheese with straw divisions, a bed of straight straw is spread on the press platform, and a mass of pomace is evenly distrib- 58 uted over it to the depth of -t or o inches. This is then covered with a second hiyer of stniw. and the operation is repeated. Tiie straw is laid on very carefully, radiating outward, the butts projecting a hit over the edge of the cheese. The workmen aic very adept in hiying up the cheese in this fashion, and produce a reinarkal)ly true even block of pomace. When completed, the edges are cut down .straight, and the pomace and bits of straw are spread on top of the cheese, and then all is ready for the application of pressure. The interposed beds of straw serve exceUently to drain the cheese when under ]irossui'e. Indeed, this method has strong features to conunend it. After removing the pomace the trough is resupplied willi fruit, and the operation is repeated. Thus one hand attends to the crushing, lays up the cheese, presses out the must, and bears it away, in this way working up about 2^ tons of fruit daily. The fruit is ground in batches, as just described, and the results of four or ti\(' lots go to make up one cheese. When this is completed, the horse is removed, and the press is started on the cheese. There are many styles of presses used, but one of very ancient type is worthy of rather extended description. The particular one liere described bore dates which indicated that it had l)een in use for two hundred j^ears, and this style was formerly the only i)ow('r i)rcs> u>ed. The essentials of this structure are two immense beams of oak. These beams are 14 inches square and 20 feet long. One constitutes the base and rests on a firm foundation to which it is securely attached. On this a short distance from one end is made fast the platform which supports the cheese. The other beam is freely movable. At the end just to the rear of the cheese platform the free beam moves up and down between two strong uprights, which are mortised through at intervals to permit of heavy cross bars being inserted to suppoi-t the beam at any desired height. The other end is unattached, save that a large wood screw passes through it and enters a huge block on top of it, which block is threaded and acts as a nut. This wooden screw is attached to the lower beam, but works freely in a socket. While the cheese is building, the upper beam is elevated, front and rear, out of the wa}^ When read}' to apply pressure, the end nearest the cheese is let down on the heav}' blocking which covers the latter, and is then securely "blocked" by means of cross bars so it can not rise. Then the other end is lowered until the beam rests fairly (»n the blocking over the cheese. Its verv weioht causes the nuist to flow freely at once, but power is now gradually applied by running doMii the wooden nut until it rests on the beam, then turning the great wooden screw slowh', by means of levers inserted in large augur holes through the same, until this beam comes into a hori/iontal position. The pres- sure is applied very slowly, the attendant bearing off the must, as it flows, to the casks in the adjacent fermentation room. When the flow of must becomes much reduced, the screw is loosened, the front 54 end of the pressure Ijeam is raised, and this causes the rear end to fall lower, so that it can be again ])locked down, after which the pressure is reapplied. This operation is repeated until the cheese is pressed sufficient!}', when it i.s allowed to drain for some time, frequently over night, after which the pomace is removed, remashed in the "tour," and repressed. When reworking this pomace, an amount of water is added equal to about one-fifth of the juice which has been expressed from it. In practice, the amount of must secured by the second pressing- is alK)ut equal to the water added. This reworking- of the pomace completes the usual routine, and a cheese of fresh fruit is now Fig. 3. — Primitive apple grater in use in Germany. ground, and laid up as before. By this system, about 400 gallons of first and second pressings are obtained daily with the labor of practi- cally l)ut one man and one horse. AVith this lever press the use of a rack or frame of any kind to hold the pomace is impracticable. Evidently- these latter appliances have come into use along with the direct screw press. A few illustrations (figs. 3, 4, and 5) showing pi'imitive methods in use in Germany are reproduced from Johannes Bottner's recent liook on cider making, but there is so little in these to commend that they will not be discussed. They arc sufficiently self-explanatory. 55 It may not be known to many Americans that John Bartiam. the pioneer American botanical collector, made and used a '-tour a aiige" cider mill on the bank.s of the Schuvlkill in the earlvdavs of Pennsvl- FiG. 4.— Primitive single-lever cider press in use in Germany. vania.

This svstera was very evidently in use in the early dajs in New Jersey and elsewhere among the colonial farmers for crushing their fruit, but no description or detailed account of its use in America has been found. 56 MODERN METHODS AND ArPLIANCES. There is a wide range of procedure in grinding and pressing cider fruit hetween the distinctl}^ primitive appliances and methods and those of the modern factory system. Machines of small and medium capacity are numerous abroad, and range from the smallest liandmills of the meanest construction, with wooden rollers for crushing the fruit, to the tinest hand and power machines of the best scientitic construction. As a general thing the mills which employ a hopper into which the fruit is thrown, whence it is fed (by gravity) onto a rotary grating or crushing device, marks the initial departure of modern machines from primitive ones. Of such machines there is a great variety in use in Europe, l)ut there is very little to commend in them with one exception, to which atten- tion will be called here- after. Many of these mills were either American machines or modifications of well-known American types, which do not need to l)e described here. But there is one type of rotary grinding or crushing ma- chine found very com- monly in Germany, l)ut much less frequently in France and England, which a])pears to deserve description and illustra- tion. The origin of this mill is uncertain, but it is thought to be Ger- niiin. It can readily be used for either hand or power work. This mill is called in German the "greif " (grip) fruit mill, and it is probably the best type for use in ordinary work. It is shown as used for hand work in tigure ♦'). In principle' this mill goes back to that of the ancient "tour a auge," viz, that of crushing the fruit instead of rasping or grating it, but it appears to accomplish this with greater perfection. The capacity, of course, depends on the size of the mill. In general, experienced persons admit the desirability of preventing, as far as possible, the contact of the pomace and must with metals such as iron. With the mills known as graters, which arc now practically Fig. 6. — The "greif " apple crusher <]f Germany. 57 the only important kind of mills on the Ameriran mark(>t. this end is not secured, for the pulp is all brought into contact with metal sur- faces. With the "oreif" machine this is not the case to the same extent. A further disadvantag-e of the grater mill, of pci-haps luore importance from a practical standpoint, is tliat the best grater mills will not continue to prepare the pomace in the l)cst manner unless the grater knives are frequenth' reground. This reiiuires time and skill, and is a distinct drawback to their use in the ordinary country factory. The "greif mill, on the other hand, can be adjusted foi- fine or coarse pomace, as ma}^ be desired, in a minute, and it has the still moi'c impor- tant advantage of reducing the fruit to pomace by bruising or crushing the tissues. The "greif "' mill in general aspect appears not unlike many American hand or small power mills, but in the essentials it is entirely ditierent. The fruit when thrown into the hopper, falls upon a slotted bottom (fig. 7). This may be made of hard wood or of metal. There is also a board slotted to corre- spond to the bottom at the back side of the hopper, which de- flects the fruit forward, so that it only comes onto the slotted bottom at the front side of the hopper. The crank or driving- wheel is attached to a shaft (d), which rests just over the slot- ted bottom of the hopper, and to this shaft are attached slightly curved arms (r), 6 to 8 inches long, which, as the shaft revolves, catch the fruit and crush it through the slots in the bottom of the hopper. One of these arms can bo seen in the section of tht^ hoi)per shown in figure 8. Thus the fruit is more or less broken before it comes in contact with the crushers. The two stone rollers which crush the fruit are shown in perspective and cross section in figure 9, and in situation at '/. figure 8. Thev are made of granite or of millstone grit, and mounted on shafts. The surfaces are cut with a slight spiral corrugation. By use of a regulat- ing screw (fig. 8, /"), one of these rollers can be made to approach the other, so as to regulate the crushing of the fruit as may ])e desired. The French and German operators wish to pulp the fruit as finely as possible without crushing or grinding the seeds. 1 '1 ® 0 |!l!li !^ ^ ® 1 1 ]lii:' e : 1 i i □ J 1 L (' 1 d ^ 1 n e a Fig. • -Slotted bottom of hopper used in "greif" machiiK'. 58 The feeding arms (iig. 7, e) are placed spirally around the shaft {d)^ so that onh' one is delivering fruit at the same moment, but this posi- tion insures a constant feed, and the size of the slots is such that no whole fruit can be delivered to the crushers. By means of the cog gearing driven from the shaft to which is attached the crank or drive wheel, the crushers are made to revolve inward at the desired rate of speed. The spiral corrugations are so cut that they cross each other at an angle which adds very materially to the crushing or pulping effect of this mill. So far as was observed, this apparatus seems well adapted either to hand or power work, and gives good results. Its most important Fig. 8. — "Greif ' apple crusher, sectional view of hopper. advantages are, (1) the pomace is not brought so much in contact with metal surfaces, as is the case with grating mills; (2) it can be regulated to grind line or coarse very quickly and with certaintv, and (3) the operator is entirely freed from the task of removing and grind- ing knives. It should be noted that the fruit must be carefully freed from stones, sticks, and the like, or a breakdown of the working parts is sure to occur. The grater mills, with spring adjusted concaves, are not nearly so liable to such mishaps. This German mill appears to be coming into favor in England. The ordinary mills of other styles presented no points of special importance. Bui. 71, Bureau of Chemistry, U. S Dtpl. Agr, Plate V!. Fig. 1.— Itinerant Cider Makers at Work in Streets.

Trouville, France. ■N;--j../ 'A y 59 American mills and presses are to be seen in use in dill'erent parts of the country. The presses used ordinarily with medium-sized modern machines are of the screw types, either with a descendinf^ screw or a screw firmly set in the base of the press am) with fallinj^ head blocks. In France most of the small mills are of the grate i- type, with adjust- able concaves for pressing the fruit firmly against the giinding cylin- der. These machines are scarcely worth}- of special illustration, but the ver}" common custom of making cider in the streets of tiie small towns and cities of the French cider districts is so uniijue ;i> to deserve some notice. It is a very connuon sight in Rennes, Trouville, Nantes, and other west coast towns to see small outfits placed in the street (Plate VI) or on the sidewalk grinding and pressing snr.dl quantities of fruit for the householders or the small shopkeepers. The mills pre- sent crdinarily no features that are unusual and are quite uniformly graters operated by hand. Sometimes the frame is mounted on wheels or wooden rollers so that it can be trun- dled from place to place. The presses likewise are at times mounted on wheels, as shown in the illustration. Practi- cally all presses used for street work are of the central screw type, the power being applied by means of a huge nut which is turned down by means of levers. The iheese i> either laid up in a crib frame or with straw divisions, as previously explained. FACTORY SYSTE5IS. In the three leading cider-producing countries of Europe are to he found well-developed factory systems differing considoral)ly from one another. Hence it is necessary to take up several types which present certain characteristics and treat each separately. FRENCH FACTORIES. Althoufrh there is much to commend in the cider fruits, the facto- ries, and ciders of the French, yet there was much one could not com- FiG. 9 —Crushing cylinders of the "preif " machine. 60 mend in their systems of manufacture. It is proposed to notice, lirst of all, one of these factories run on wliat seemed to be question- able methods. There is a ver}^ modern school of French cider makers, whose claims and pretentions deserve more than passing- notice, especially since it is proposed to introduce their system into the United States. The system referred to is known in France as the Noel system, and involves pretended secret processes which it is claimed perform wonders in the handling' of cider fruit, the storag'e and keeping of ciders, etc. The writer had several conferences with the promoters of this scheme in Paris, and was offered full instruction in the methods for a period of seventy or eighty da3^s for 30,000 francs, on condition that the methods should never be divulged! During- these conferences Fig. 10. — Fermentation and storage room, Noel system, France. and later in visiting some of the factories it was ascertained that the so-called system consisted of nothing peculiarly valuable. The pro- cedure was much the same as in other factories. The fruit was ground and pressed, then the pomace was exhausted by diffusion with warm water, a method often used in France, and the resulting nuists were united and sugared to a condition which would make a fair cider. A great pretense was made of securing valuable principles lost to others by exhausting the marc in warm water. By sugaring up the weak must secured by exhausting the pomace with water, about double the quantity of cider is made that can l)e usually obtained b}" using pure juice. This is truly an old secret! However, the plan of one factory which was twice visited is quite uni(|ue, and for that reason is pre- sented somewhat fully. The building is a line new brick structure in a suburb of Versailles. The surroundings are much like those of a 61 homo. The family lives in the front of the .structure, and here the office is also located. Extendino- back from the front is a rectan^'-ular structure two stories hiph and about -io feet wide l)v lijO feet loiiu'. The lower story of this rear structure conij)ri.ses one large room with very heavy brick walls without windows. This room is entered from the front by large doors, and has a rear dooi- of smaller size. Along the sides of this room, against the walls, ai'e ran<>-ed iri'cat tanks al)out 60 in number with total capacity reaching po.ssibly 2(M),(HI() gallons. The illustration (tig. 10) shows a perspective view down the center of the room. Each tank is furnished with a faucet near tlie bottom, and a glass tube connmuiicating with the interior rises the full heiuht of the tank, showing at a glance the height of the licjuor within. The top is tightly closed, but a manhole for entering the tank and taps for introducing the must arc provided. The center of this rotjm is occu- pied b}' casks, pumps, and paraphernalia for racking and handling the cider. Also great cart loads of fruit in sacks are brought from the railwav station, driven to the center of this floor, and elevated to the upper story by a power lift, worked V)y a gasoline (Migine in the second story. The second story is used to store fruit, and here is also located the grinder, the gasoline engine which furnishes all the power for the plant, and the tubs or tanks for exhausting the pomace. The fruit for grinding is thrown into a tank of water in which rests the lower end of an elevator screw which lifts it to the grinding cylinders. From the grinder the pomace falls into the press, where it is m:ide up into cheeses after the American fashion and pressed immediately. The object of throwing the fruit into the tank of water is to wash it. whieii is fairly well accomplished by the motion of the elevator screw. The exhaustion of the pomace after pressing is accomplished by diflusion with warm water, as already stated. The operations of blending and sugaring were not shown, nor were the details of the sj^stem of fermenting and racking explained other than in \ ague terms. However, the must is both fermented and stored on the tir>t floor and is run off into casks for market as desired. The product, as sampled in several stages of manufacture, was very inferior, and had little resemblance to that of standard Normandy ciders. This factory is making about 200.000 gallons of cider annually. The construction of the factory, arrangement of machinery, tanks, etc., is quite unique, and apparently advantageous. A characteristic of the French "cidreries" was the almost total absence of cellars. Thus, in the factory just described the storage is wholly above ground. This is the rule in Franco, while just the opposite is true of Germany. Za Cldrerie de T Zhvwn Agrtcolc.—Th^ best type of factory examined in the French cider couutrv is that of an agricultural union at St. 62 Ouen-de-Thouberville, a short distance from Rouen. This establish- ment, built and operated upon a cooperative plan, is a model in its mechanical appointments, and the technique of its operations seemed to leave little to be desired. The general manager is Monsieur Gus- tave Power, the noted authority on pomology, whose books have been ^ oflScially adopted by the minister of agriculture for use in the schools of France. The writer was most courteously received by this cultured gentleman, and given every facility to examine and study the details and methods of the establishment, which is, perhaps, representative of the best type in France. The ground plan of the main factory is shown in figure 12. In total dimensions, the building is approximately 800 feet long by 100 feet wide. A study of the vertical longitudinal section (fig. 11) will help to give a clear idea of the plan and w^orkings of this factory. It will be seen that to the rear of the main operating room of the ground floor one can step up a few feet into the main fermenting room, or down a few feet into a half-cellar used for the finishing processes of fermen- tation and for storage. The surface of the ground slopes from the front to the rear of the building, so that this lower room ends at ground level. This gives an important advantage in the ease with which the finished product can be loaded on trucks for transport. The operation of this factory will be better understood b}^ following the usual course of the fruit and must as the}^ pass through the sev- eral processes to the finished product. The carts laden with apples in sacks enter the shed in front of the factory, and ])y a hoist, operated from the main shaft within, the fruit is lifted to the second floor, where it is weighed and put in bins according to varieties and qualit3^ These bins cover nearly all of the second floor, and are only 18 inches deep, strict rules as to methods of storage being observed. With the fruit thus distributed, it is possible to observe critically its condition and to grind as it comes to proper maturity; also the careful distribu- tion in accordance with the quality makes it easy to blend the fruit so as to "produce desired grades of must. When ready to grind, the fruit is measured to the machine in proper proportions. The grinder stands at the floor level of this storeroom. Formerly the fruit was washed, but now this is only resorted to in case of necessity. The fruit is, however, run over a slatted ''way" or chute in its progress to the cylinders and much trash is screened out, an attendant watching that foreign substances likely to damage the grinders do not pass. From the grinders the pulp drops into a chute, which delivers it at the pleasure of the operator into one or another of the several pomace vats. The custom is to fill one after another of the vats, the pulp being allowed to remain for some hours before pressing. This maceration of the pulp in its own juice is thought to aid in extracting the sugar content and to give better color to the must throus-h certain chemical changes caused bv the action of 63 64 the ail- on the crushed tissues. The pulp is not, however, and never should be, allowed to ferment before pressing. The pulp vats at this factory were made of porcelain tiles carefully set in cement. A drain pipe was arranged to carry the must, which always 65 flows from f reshh' crushed fruit, into a cistern at the left of these vats. From here it was pumped into the laroe casks in the fermentation room. The large vat (tig-. J 2, h) is provided for the maceration of pomace after it has been through the press. When the pulp is thought to ])e in condition for the press a small car is run alongside and the pulp is laid up in cheeses on a form, using coarsely woven press cloths just as is done in the ])est American fac- tories. When this car is loaded it is run onto the press (/>', tigs. 11 and 12), and the hj'draulic pump is put in motion, the car and its load of pulp l)eing lifted by the upward thrust of a hydraulic piston after the manner so common in this countrv. In this factorv the hvdraulic presses were rated at 200,000 pounds direct pressure. While this load of pulp is under pressure another car is loaded ready to take its place. On being released from the press the car is run alongside the large vat and the pressed pomace is discharged into it, carefully cut up with a shovel and wet with weak must or water, the amount of liquor added ])eing a])out equal to the pure juice expressed. This round of operations is repeated until the day's grind- ing is exhausted, and the pomace from the tirst pressing then rests in the large vat macerating in water or weak must until thought ready for pressing a second time. The must from the fresh pulp in the vats and cistern is united in the great casks of the fermentation room as pure juice. This is destined for the highest grade cider. After eight to ten or twelve hours maceration the pomace is again subjected to pressure on a different press {D, tig. 11) from that used for pure juice, and the must is received in another cistern near by and pumped into another set of casks. This must is used to make a second grade of cider, the "boisson" of the laborers. But this does not complete the operation. Again the pomace undergoes maceration with water or weak must, being then pressed a third time. The must from this pressing is very weak, its specific gravity being l.olo to 1.016. This must is used to macerate the pomace after the tirst press- ing, thus adding very material!}' to the quality of the must derived from the second pressing. The pomace is no longer of any value for cider purposes. It may, therefore, l)e discharged bv running the car outside the factorv, or it may be ground anew and washed to separate the seeds, which return no small income, as they are in great demand by luirserymen for growing stocks. These seeds are known in commerce in this country as French "crab seed," but they are really seeds of the cultivated apple and not of crabs. A second method of extracting the juice from the apple pulp is also employed in this factory, viz. diffusion. The diffusion battery ((r. tig. 12) is located at the extreme left of the main operating room. It consists of 6 tanks, about 3i to 4 feet high, mounted on a turntable. 17247— No. 71—03 5 66 Immediately at one side and just above the level of the tanks is a res- ervoir for water. This ma}^ be supplied warm or cold. To put this apparatus in operation, 5 of the tanks are tilled with cut or pulped fruit. These are so connected that the Huid will circulate from one tank to another by means of a tube connected at the bottom of the first and delivering the flow near the top of the second, and so on around the circle. By the time the fluid flows out from the bottom of the fifth tub it is well charged with the soluble matters contained in the fruit, i. e., sugars, acid, tannin, mucilage, etc. But it can never be made to equal in richness the product of the first pressing from the same fruit. As soon as the fruit in the first tank is exhausted by this washing with water, the stream is turned into the second, and the sixth tank, now freshl}^ filled with pulp, is put in service as the final member of the battery. Then the first tank is emptied and refilled with fresh fruit to take the last place in the series, when the third tank becomes the first cell in the battery. Thus the operation proceeds indefinitely. It should be said that the richness of the must delivered at the exit from the fifth cell alwa3^s determines when a fresh tub or cell must be ""cut in," as the flow through the last tub of fresh fruit strengthens the must very much. The strength or richness is taken by specific gravity very readily. The manufacture of cider by the difl'usion method is carried on in France to a considerable extent, but its present importance does not appear to warrant extended discussion here. It may l)e worthy of study, but all the indications seem to point to its failure to produce a genuine high-grade cider. In the factory at St. Ouen-de-Thouberville two hand presses were provided as a reserve to be used in case of accident to the hydraulic presses. The main operations prior to fermentation have now been outlined. The must of the several grades has been delivered by pumps to the large casks in the fermentation room (figs. 11 and 12). Through each section of this part of the building runs a main brass pipe connecting with the pumps. The flow is readily turned into the desired section by valve cut-offs, and in each section the must is delivered to the receptacles by rubber tubes which can be attached to the "main" at convenient points. Each cask as filled is marked with the date and such other data as are necessary to guide the operator in the details of the fermentation. At the same time proper entries are made in the factory journal for future reference. The technique of fermentation is not discussed here, as it will be treated further on in this report. It should be added, however, that Mr. Power was using casks usually of 600 liters capacity or larger, open vats made of slate, and great tanks ))y way of experiment during the first fermentation; but his preference was for the casks. J G7 From the upper room, where the first fermentation occurs, the cider runs by gravity at tirst racking to the room helow, which is a sort of half cellar. Here it usually rests until it is tinished cider. The rail- ways shown on the ground plan are in this lower room and serve to carry the tinished cider in casks of proper size for transportation to a platform at the lower side of the factory, from wliich they are rolled onto the great carts without lifting, an advantage of considerable importance. The space shown in the illustration, however, is not sufficient for the product of this factory, and five cisterns adjoining the lower store- room augment the storage capacity by 60,000 gallons. These are made of slate laid in cement, and the cider stored in them keeps per- fectly. When it is necessary' to bring them into use, the cider flows by gravity to them from the lower storeroom. They are carefulU' closed as filled, and only opened as it becomes necessary to pump the cider out for commerce. This factory has a total annual capacity of about 350,000 gallons. The laboratory is of very great importance, and here Mr. Power makes analyses of fruits and of the product at various stages of manufacture so that all may be well governed. GERMAN FACTORIES. Among German cider makers of the Taunus and Rhinegau districts to propose fermenting the must in other than good cellars would be heretical. The cellar is here the first essential. Everywhere the small proprietor and the great manufacturer work on essentially the same principles. These cellars are most excellently built of good masonry, the walls being finished in hard mortar and the floors iu cement, as though they were intended to endure for ages. Drainage, ventilation, hoists, and the like are carefully looked after. Dr. Cluss, in his recent work on cider making, bemoans the careless- ness and lack of method observed in some parts of German}', but in the districts visited by the writer the people have the details well in hand. Only a few types of factories which illustrate those seen can be taken up in this report. The mills most generall}" in use in Germany for grinding or crushing the -fruit are either single-cylinder rasping or grating mills or two- cylinder crushers ("greif '' mills.) The simple grater mill serves its purpose very well, but the consensus of opinion seems to ))e decidedly in favor of the stone cylinder crusher (figs. (5-9). This mill, in dif- flerent sizes, was found in use. some being driven by small steam or gasoline engines. In fact small factories with good appliances and good cellars are quite common in the territory visited. The German cider maker may have a building devoted entirely to that purpose, as the large makers invariably do, or, as in the case of farmers and other small makers, he may use only a portion of a build- ing, the balance being used for other purposes. The grinding and 68 pressing rooms may be additions built onto another structure, the cellar extending under the whole. In no ease Avas fruit seen stored in upper rooms or lofts, but usually on the floor of the operating room or in bins adjacent. The suiall makers seem to make little or no provision for storage, and the g-rinding and pressing, so far as observed, were con- ducted on the ground floor. In the small plants this requires onl}" a moderate amount of floor space, the power plant and grinder being near each other and the presses adjacent. The pulp was almost invari- ably allowed to stand for some hours before pressing. The Germans usually have large tubs, holding-, say, 10 hectoliters (264 gallons) of fruit pulp, and into these the crushed fruit is at once placed as soon as it falls from the mill. Even the largest factory visited, having an annual output of over 500,000 gallons of cider, pursues this rather cum- bersome method. In large factories this requires a great amount of floor space and seems to necessitate an enormous waste of labor, liut it is thought satisfactory by the proprietors. Small plants usuall}' grind onl}^ enough fruit to make one or two cheeses at a time, and hence proceed at a rate which, in this country, would be considered wasteful of time. The manner of laying up the cheese is in the main the same as in our best appointed mills in which cribs n.re still used to hold the pulp during pressing. The cheese cloth has not made headway in Germany. The cribs, usually circular, are very well made. After maceration for a period varying from twelve to twenty -four hours, the pulp is brought to the press and submitted to as heavy pressure as possible by hand power, the drop screw press being largel}' used, but also those with the screw on a central stem. The pressure is applied for a considerable period until the cheese is carefully drained; then the pomace is thrown up and flnely Ijroken, and either macerated with water, as in France, or allowed to rest for a period when it is pressed a second time in a stronger press. The Germans do not use much water in macerating pomace for repressing; in fact, a very small amount was used where the operations were observed. The best German factories inspected did not use water at all, but these were equipped with hydraulic as well as hand presses, and the press- ing was completed at a pressure of 250 atmospheres on the hydraulic presses. The difierences between French and German fruit in sugar content have some bearing on the use of water in macerating. At no time was must observed flowing from the press in German mills which was above 50'-' Ochsle (1,050 specific gravity), and if, after watering slighth^, a second pressing of -10- to 45 Ochsle (1.040-1.045 specific gravity) could be obtained, the two runs were united and fermented together. This was the practice in small factories. The largest German factory visited, that of the Freveisen Brothers, Frankfort, is possibly the largest in the world. Its annual output is <)9 about 25,000 hectoliters (060.000 g-allons). Unfortunately plans of this building were not to be had, and it was too extensive for the writer to attempt making drawings. The working e<(uipment consists of one grinder, a large imniber of mash tubs in which the pulp is macerated, 22 presses (6 of these h3^draulic), teams, tools, etc. A force of 160 laborers is eniplo3'ed. In this factory, and alsi) in most of the smaller German factories visited, the fruit is washed before grinding, usually in the manner already described, namely, by dumping it into a great vat of water and elevating it from this to the grinder by a screw rotating in a half cylinder. The workmen carry the apples from the bins in wooden vessels resem- bling tubs, holding about a bushel, and dump them into the washing vat. The pulp is taken in like vessels as it falls from the grinder and carried by the workmen to the macerating vats. From these, after maceration for about twenty-four hours, it is again filled into the tubs and carried to the presses. The pressure is applied slowly, jind the pulp is allowed to drain a long time. Then the pomace is cut up fine, put into another press, and re-pressed without addition of water. The third and last pressing is accomplished at 250 atmospheres. No further use is made of the pomace. The nuist averages about 1.050 specific gravity. To an American the work of this factory seems to be conducted on an exceedingly laborious plan. The impression obtained was that this old firm, which had been in ])usiness about a century, had at various times grafted on new ideas and appliances, without at any time really reconstructing and modernizing the plant. In like manner, the cel- lars appeared to have been added to until they honeycombed the earth, and extended vault below vault to a depth of 17^ meters (56 feet) below the surface of the factory yard. This bewildering maze of cellar vaults, full of great casks, each holding 2,000 liters (528 gallons) or more, over 900 in all, served to store the product; but a great quan- tity of cider is sold while still in first fermentation for use in the res- taurants of Frankfort as sweet or smoking cider. The methods of handling the must are now to be considered. The pressing of the pomace, as explained above, generally occurs on the ground floor immediately over the cellar. To this first cellar the fresh must is conducted through rubber pipes, either by gravity or l)y pumping, and is put directlj' into the great casks in the fermentation room. It is the German custom not to fill the casks so full that there will be any discharge of froth or top lees through the bunghole. 6 or 8 inches of clear space being left in the top of each cask. As soon as a cask in the fermentation room is filled, it is fitted with the ventih\ting funnel (fig. 16). Nearly all good cider factories are provided with cellars at least two stories in depth, so that the room for final fermen- tation and storage is immediately below the first cellar. 70 The construction and arrangement of t3"pical German cellars are shown in iigures 13 and 14, The most ordinary place visited had one good cellar, and places of the next higher grade uniforml}^ had two- stor}^ cellars. The great factories have still deeper cellars, as that of the Freyeisen Brothers already mentioned. The chief advantage of the cellar is the ease with which temperature can be controlled. For instance, in the upper cellar, b}^ introducing air through ventilating flues (fig. 13 //), it is possible to raise or lower the temperature in accordance with the condition of the atmosphere, and once the proper temperature is reached its maintenance is fairl}' Fig. 13.— Vertical cross section of small German cider factory with arched cellars. easy. However, in the cold season, if the temperature falls too low, resort is had to a heating apparatus. The temperature which the Ger- mans seem to prefer for the fermentation room (B, figs. 13 and 14) is 15° to 18° C. (59° to 65° F.), the lower figure being preferred if active fermentation starts promptly at this temperature. In the lower cellar ( 61, tig. 14) or finishing room a temperature of 8° to 10° C. (45° to 50° F.) is preferred. Still lower temperatures are obtained in late fall and winter. The comparative ease with which the cider can ])e piped from one cellar room to another under this German svstem is very apparent. 71 The liquor must, in the course of its progress to a finished product, pass from a warmer to a colder temperature, and this is here accom- plished I)}' g-ra\itation. The hoist (tig 14, >) at last lifts the finished product from the lowest room to the ground Hoor. Naturally the great casks are never disturbed except for purposes of repair or reno- vation. The finished product is either l)ottled direct in the storage room or transferred to smaller casks for transportation. Maidioles are provided in the floors of each room to permit the passage of the pipes, etc., used in handling the product. v-i-r Fig. 1-1.— Vertical cross section of two-story German cider cellar. ENGLISH FACTORIES. There is little that is distinctive about English cider factories. This does not imply that there are not good factories in England; on the contrary, some of the finest products observed anywhere were those of English factories. But there is no definitely recognized standard in regard to either apparatus or buildings and cellars for either small or large factories in England. The best factories seen were copied from those of the French champagne makers of Epernay; but as to mechanical devices or details of arrangement, they show little that is new or of peculiar importance. The cellar plays but a small part with r^ the average English eider maker. Some important details, however, in the handling of must and in fermentation processes were observed. The English factories grind largely with graters and rasping cylin- ders, though the German ''greif "■ machine (tigs. 6, 7, 8, and i)) is com- ing into use.. As before mentioned, the ""tour a auge" was seen in use in England. The English rarely press the pomace but once, and almost no maceration of the pomace with water was observed. The quantity of juice extracted from the fruit varies, according to the statements made, from 60 to 90 per cent of the weight of fruit, l)ut the latter tigure is so high as to inspire grave doubt as to its correctness. The presses used are mostly old-style hand and power screw presses. Not a h3'draulic press was seen in use in the island. The system of handling the fruit at the large factories seems particularly objectionable. It was in most cases lying in great heaps in the yards or lots adjacent to the mill, and in many cases a considerable percentage of it was far gone with decay. On a tenant farmer's place in Herefordshire was seen one of the largest plants visited in England, and a few words of description will give an idea of its management. The fruit lies in immense piles in the orchard on a rise of ground which extends up to the factory sheds. When needed, the fruit is shoveled into a long inclined chute that carries it to the grinders below% which are of the stone-crusher type. The pulp falls into a great vat, whence it is shoveled onto the presses. Two sprocket-geared power presses are used, and the cheeses are laid up in cloths as with us. In this factory the pomace is soaked and re-pressed. The must is pumped by power apparatus to an adjacent shed, where it is received in great slate vats and wooden tanks, and in these it is carried through the first fermentation. From there the cider is pumped to a more permanent building for ripening and storage. The storage tanks range in capacit}' from 100 to 4,500 gallons each. Fermenta- tion is controlled by iiltering and racking, as is usual in England, and a pasteurizer also is in use, but no opportunity offered to observe the effects of its use. When desired for market the cidel- is blended in large vats to suit the demands of the trade and then pumped through the Invicta filter into casks for shipment. Thousands of gallons of supposedly finished cider were to be seen stored in 50-gallon casks in the open, merely covered over with boughs and straw, and it was said to keep well under this treatment. The power used in operating this plant is a traction engine of about 15 horsepower, such as is in general use on English farms for thrash- ing and doing various kinds of heavy work. The whole plant was very badly placed as to detail pf structures and conditions for han- 73 dling the product properly. Practical duplicates of this factory were observed elsewhere, and very fair cider was made on a larjre scale, but no really tine products from such plants were observed. The best larg-e factory visited was at Hereford City, but here admit- tance to the operatino- rooms and cellars was refused, thoutrh an extended interview on the methods was given. These operators are patterning- wholly after the French champagne makers. They have extensive cellars in which their product is finished at a temperature of 47° to 50° F. They explained their system of blending the must before fermentation, which, by the way. is one of the most important operations in determining the grade of product pi-oduced. On the estate of Lord Sudley, in AVorcestershire, some very inter- esting and decidedly successful amateur work in cider making was observed. Here the manager of the estate, Mr. Charles D. ^^'ise, has for several years been studying and experimenting on the manufacture of fine bottled cider and perry, and he has succeeded remarkably well in some particulars. He has installed a small plant in a great circular brick structure, formerly used as a riding school. Here he grinds the fruit on a grater machine, using a portable farm engine. The pulp is pressed bv a hand-power screw press, and the must is carried through the first fermentation in great tubs or vats. As soon as the lees are well separated, the cider is racked ofi' and then filtered by gravity through wood pulp. This is accomplished by the use of a great tub elevated about 10 feet above the floor. In it is fitted a false perfo- rated bottom, a few inches above the real bottom, and between these is placed the filtering medium. The tub is filled with cider, and the clarified product is received below and placed in large casks about the course of the riding school to mature. The cider is permitted to remain in these casks from one year to eighteen months before bottling. Apparently ver}- little techniijue is employed, but some of the product is excellent. How much failed to turn out well was not ascertained. The experiments on cider making in England, conducted conjointly bv the Board of Agriculture and the Bath and West Agricultural Society, are carried on at Butleigh Court, the country seat of K. Neville Grenville, esq., in Somersetshire, near Glastonbury (PI. VH). Mr. Grenville is personally interested in this work, and has devoted con- siderable time and money to it, and Mr. F. J. Lloyd, of London, a consulting chemist, has supervised for the authorities the more techni- cal aspects of the work. The reports on this work can be found in full in the annual volumes of the Bath and West of England Society. The cider house at this place is equipped in part on French models. The fruit is stored in a loft, and is ground on a machine at the level of the upper floor, whence the pulp falls to the press >>elow. The grinder is of the German pattern with stone rollers. The pulp is pressed on a 74 . hand-power screw press at about 40 tons pressure. The cheese is laid up in cloths and well pressed, but onl}' once, the pomace being then used to feed the cattle on the place. The must is pumped ])ack into the upper story and placed in open tanks (here called "keeves") of about 00 to 75 gallons capacit}". In these the must is carefully watched, and the top lees are skinmied ofl' until the cider reaches a state of limpidity wdiich warrants racking oli'< At this stage the liquor is drawn otf in pipes to the lower room and either placed direct!}' in casks for maturing or run through the Invicta filter, according to circumstances; that is, if the cider can be drawn clear, it is best run directly into casks, but, if "troubled," it is filtered and then run into casks. The storage casks range in size from 100 to 250 gallons. In this small factory all the critical data which should govern the technique were observed, as, for instance, the chemical composition of the fruit and the specific gravity of must at grinding and at each stage of fermentation. A most elal)orate cellar record is kept of the casks in the storage rooms and regarding the results of bottling at various times. It is too soon to speak positively of the lessons to be learned from these examinations and observations, but it is certainly by such observations and studies that the knowledge of the subject is to be advanced. The product sampled at Butleigh Court was of fine quality but, as elsewhere, there were "misses" in some cases. Accommodations for accurate cellar work are needed. PRODUCTION OF THE MUST. The appliances used in reducing the apples to pulp and expressing the juice therefrom have already been described. Yet several impor- tant points in relation to the production of the must remain to be discussed. RIPENESS OF THE FRUIT. The ripeness of the fruit, or its condition in relation to those obscure processes which go on after maturity in the pome fruits and bring them into their most favorable condition as to quantity of sugar and quality of juice, is a very important consideration in this connection. It was especially noted in the French factories that they did not grind the fruit until it was in perfect condition as to ripeness, but com- paratively little attention was paid to this matter u\ the German and English factories visited. The important fact that the sugars in fruits increase to a maximum point, which is doubtless reached at or near the stage of perfect ripe- ness, ought not to be lost sight of either in cider or vinegar work. There are, however, very few valuable data concerning the composition Bui. 71, Bureau of Chemistry, U. S. Dept. Agr. Plate VII. Fig. 1.— Butleigh Court. Somersetshire, England, Seat of English Cider Experiment Station. Fig. 2.— The Cider-apple Orchard at Butleigh Court. 75 of apple.s during- the process of ripening. This is an important field for critical stud}' which ought to give results of decided economic value. MIXING VARIETIES OF APPLES. Under the comparison of the composition of fruits, the great vari- ability of diti'erent kinds of apples has been shown. But there are other characteristics of apples which can not be expressed in terms of chemical data, such as their taste and aroma, and these factors have to do with making a good cider in only a lesser degree than sugars, acids, and tannin. The blending of fruits at grinding appears to be an almost universal practice in France. Every maker appears to exercise his own judgment a])Out the proportions of the several varieties to ])e used, sampling the fruits by taste and smell. There an', for instance, many French varieties which have a very high content of tannin. These are not used separately in cider making, but are mixed with sweet and acid fruits to secure a proper average composition. The question of blending or not resolves itself tinally to this: Can we hope to secure by selection a perfectly proportioned fruit as to its chemical compo- sition and other (|ualities, or not? This desideratum is certainly far from being realized at present. In German}" very little special attention is paid to the subject of blending except in the use of So7'hus domestical as already noted. In this they have a fruit of the greatest importance, a fact which did not appear to be fully realized. The ordinary German varieties of apples present few characteristics to lead one to a study of blending. In England the best makers talk about blending, but handle their really good varieties in such a l)ad manner, in many cases, as to leave little chance of realizing the best results. At one of the best English factories visited the manager explained that he ground the varieties separately, expressed the must, tested it as rapidly as possible, and blended as it was run into the fermentation casks. This is certainly the most scientific method of l)lending. Some French writers recommend for the best standard ciders to use one-third sweet fruit to two-thirds bitter fruit, and for household u.se two-thirds sweet and one-third l)itter fruit; but such attempts at exact proportions are worthless. The whole question nnist be determined on the spot for the particular fruits in hand. However important this question may be in relation to standard products, no really impor- tant data regarding it were obtained. Unfortunately in the United States we have so few distinctively cider fruits in cultivation and so few technical data in regard to our common varieties that advice on this point must await further investi- gation. Meanwhile, good judgment applied along the lines here indi- cated will be a better guide than figures as to proportions of this or that variety. 76 WASHING TUK FRUIT. In many places in Germany and some places in France washing the fruit before g-rinding was found to be largely practiced. Where the fruit is actually soiled this operation is greatly to be commended, but it was practiced in many places regardless of this point. To run all fruit through a washing vat simpl}" as a part of a system seems to be unwarranted on several grounds: (1) It is useless in case of fruits that have been harvested in a proper condition; (2) if elevated directly from the washing vat to the grinder the fruit carries with it consider- able water, which reduces the specific gravity or richness of the must, and (3) there is every probability that washing reduces considerably the 3'easts present on the fruits. This under some conditions is of critical importance, and needs to be considered in relation to the practice of sowing the must with active yeast cultures. There are heard in discussion and found in the literature of the subject statements about diying the fruits after washing, but this does not seem to be practiced, nor was a mill seen constructed with any idea of permitting the fruits to dry before crushing. If the water is not fre- quently changed in the tank it will soil rather than clean the apples. Fruit carrying impurities should never be stored or ground with clean fruit even after it has been washed, as to do so is simply to furnish to the must the organisms of mal-fermentation and other substances, which will most likely prove harmful. The international cider congress held at Paris in October, 19<»0, expressed by vote the opinion that washing fruits before grinding ought only to be practiced whtire cleanliness made it necessar3\ GRINDIXG OR CRUSHING THE FRUIT. The end in view in reducing the fruit to pulp is to make it possible to extract the juice by pressure. Some fruits can be more or less per- f ecth^ pressed without grinding, but this is not possible with the apple. The cells of the apple hold their juices quite tenaciously, and must be definitely ruptured. Hence the method which will most perfectly rupture the constituent cells is probably the best to employ. As pre- viously stated, perhaps the German "greif " mill accomplishes this purpose better than those of an}^ other type. This view was advanced by German and English cider makers, and indorsed to some extent by the French. It was everywhere stated by the best makers that the seeds must neither be cut nor crushed to any extent, because their oily and nitrog- enous constituents directly injure the ciders by contributing flavoring matter of an unpleasant nature and nitrogenous substance in which the organisms causing putrescence find a desirable medium for develop- ment. This opinion was universally accepted in all the factories vis- ited, although this view is contrary to that of the early English and 77 American writers. The chemical analj'.ses of seeds of pome fruits indicate that the opinion is based on good orounds. The delicate fruit aroma yields the Ijoucjuet desired in the cider. The oil\' principle in the seeds tends to destroy this, and certainly nitroyfenous matter is not desirable to any extent in must which is to be fermented into a beverage. There is ordinarily plenty of nitrogenous matter in apple must to support yeast growth. Howeyer. slightly contradictory as it may seem, the French makers aim to crush the seeds for the prepara- tion of ''boisson," claiming that, as the pomace is largely dcpiiycd of its aromatic constituents when the pure juice is extracted, the oil in the seeds adds to the (piality of this low-grade cider. The fineness of grinding attects to some extent the facility with which the juice can be expressed. If the pulp is too nmshy. it presses badly, especially when the cheese is made up in cloths. In this matter there is a proper mean, which no one seems to be able to define in an entirely satisfactory manner. It is often expressed in this form, that not over 2 per cent of the seeds should be cut or crushed in reducing the fruit to pulp for first pressing-. For preparing nuist by the diffusion process, mentioned elsewhere in this report, the fruit is not ground or crushed as for pressing. l)ut it is cut or shavsd into thin slices, as it is found that with these extraction by diffusion goes on more perfectly than with pulped fruit. MACERATION OF PULP. The Germans are strong advocates of maceration, i. e,, allowing the fruit to stand in its own juice, because b}" this process they believe the sugar is more perfectly extracted. They claim that the juice acts upon the unbroken cells and assists in liberating their liquid contents. This would certainly be true if fermentation were fairly bt'gun before pressing. The writer's experience is against permitting the pulp to ferment before pressing, but these questions need to l)e approached from the standpoint of scientifically conducted experiments before much can be said that is definite. MM. Seguin and Pailheret, at the National Agricultural College, Rennes, France, have made a number of experiments in a small way upon this question and they have found in every instance that macera- tion increases the totals of sugar, acids, mucilage, and ash in the nnist, but decreases the tannin, and leaves, finally, an almost colorless nuist. This latter point is contrary to the German opinion. The French do not generally practice maceration of the pulp before pressing. In the writer's opinion maceration for more than eight or ten hours is liable to stock the whole mass of pulp Ayith many undesirable organisms and render control of the fermentation far more difiicult than it would otherwise be unless the pulp is sown at once on grinding with pure cultures of veast. 78 EXPRESSING THE MUST. The older methods of laying up the pulp preparatory to pressing- possess no particular merits to call for further remarks than those already made. The modern, double-acting, ratchet screw presses, so much used by the French, and the hydraulic press, or some better form of machine, must be the presses of the future. Hand hydraulic presses are in use in France, and in all the medium-sized and large factories these mod- ern machines must make headway against the obsolete and laborious hand presses of the old style. When the fruit is carefully pulped in the most correct manner, and subjected to from SO to 1()0 tons direct pressure for a sufficient length of time, the possibility of again manipulating this pomace so as to derive sufficient must to warrant the effort is indeed slight. This is especially true when the pulp is well laid in thin lozenges in the coarsely woven seine-twine cloths used in the best American mills. Hair cloths and various devices are used abroad, but none of these compared well with our best American cheese cloths. SOAKING THE POMACE. One must distinguish clearly between the after maceration of the pomace and the maceration of the pulp in its own juice. The later operation is better named '"soaking."" If there is any method by which the pomace can ever l)e handled with a view to more perfectly exhausting it than is accomplished b}- direct pressing, it would seem that soaking in warm water is by far the most promising one. If American fruits were as rich in saccharine properties as the French appear to be, it is possible that a considerable quantity of the juice of second pressing or of the must extracted by diffusion could be mixed with the rich juice of tirst pressings and still produce a must sufficiently rich for good cider or vinegar. The imperfect methods of expressing the juice employed in many places abroad give to this question more importance than it has with us; but the question of its utility or nonutility in large factories is yet to be settled after more technical investigation. FERMENTATION OF CIDER. In the minds of some, fermentation is a very simple operation. Mr. A. Hauchecorne says in his elementary treatise on cider:'* "The art of making good cider is very simple, and includes the following four conditions: Ripe fruits, clean water, a barrel free from taints and odors, and later racking off."' On the other hand, Mr. G. Power'' says: '•Of all the operations necessary in the manufacture of cider, the fer- «Le Cidre, p. 7. ^Culture du Pommier et FaVjrication du Cidre, 1: 102. 79 mentation is certainly the most diffieult and the most important. This is true of all beverages, but with cider on(> encounters difficulties of a special nature." Dr. A. Cluss," writing of North German}-, nSLys: We shall now speak of fermentation and the management of the cellar, those fac- tors which have the greatest influence upon the resuhant product, and * * * in which the greatest faults have been committed. One can say without exaggeration that the misfortunes in making cider, about which so many moan, are due not to the poor raw material nor to faults in the pressing, but ahnf)st without exception to ignoi'ance of the foundation principles of fermentation, and especially to the bad condition of the cellars and cellar utensils which universally prevails. The above quotations illustrate the extremes of opinion on this sub- ject. Everyone in the United States who has tried to make tine sound cider will, I think, agree heartily with Power and indorse with- out exception the views of Dr. Cluss. ROOM, VESSELS, AND APPLIANCES USED. The first object to be kept in view in the construction of a fermen- tation room is the control of temperature conditions; the second, con- venience of location to the general operating room and to the final storage room; and the third, facilities for maintaining perfect cleaidi- ness and ventilation. As types of factories meeting these requirements to a considerable extent, the factory at St. Ouen-de-Thouberville, France, and the Ger- man factories having single and double cellars may be cited. • On beginning the season's work the fermentation room should be put in perfect order as to cleanliness, the walls and floors being newly whitewashed. The casks or vats should be put in the most perfect order, cleansed carefullv inside and out, and arranged with reference to the convenience of tilling, racking ofl', and other operations. TEMPERATURE OF FERMENTATION ROOM. On this point the Germans are much more careful than the French or English. The French structures arc largely exposed to the influ- ence of daily fluctuations in atmospheric conditions, and whenever there is a considerable daily variation in the temperature it is quite impossible to carr}' on an even, well-ordered fermentation. The alcoholic ferments (commonly called yeasts), like all other jilant organisms, have an optimum temperature for growth, and it has been determined that this temperature is about 18- to '24 C. (05- to 75^ F.). But it is also true that, at this temperature, the growth of the yeast plants is apt to be very rapid, producing a rather too violent fermen- tation which disturbs the orderly management of the must. At a lower temperature fermentation can be carried on in a more orderly way, if once well started, hence, 18" to 18° C. (55'= to 65° F.) has been «Apfelweinbereitung, p. 61 et seq. 80 found a more desirable temperature for the main fermentation room. At a temperature reduced much below the minimum g-iven the must will not start a proper fermentation, and when it is introduced into the casks — especially if they are large ones — at a lower temperature, some difficulty will be experienced unless the must is artificially warmed. This can be accomplished by warming a portion and pour- ing this into the casks, but this portion of the must should never be heated to a temperature above 50^ or 00^ C. (120^ to UiP F.). VESSELS USED IX FERMENTATION. Many styles of casks or vats for the first fermentation are in use. In England open vats were f requentl}^ seen. These were of wood and slate, and held from 60 to several hundred gallons. They were placed in the workrooms, or in rooms adjacent thereto, or out of doors under a shed roof. Many English makers, however, carrv on the first fer- mentation in casks both small and large. Some use inferior 50 to 60 gallon casks lying in a shed, or in the open, ])ut the best makers use larger casks or vats holding 100 to 500 gallons, and even larger ones for the tumultuous fernientation. Those who use the open vats quite generally allude to this part of the process as "keeving" the cider, plainly a corruption of the French word "cuvage." French makers very largely ferment first in immense casks holding from 500 to 1,200 gallons, but they also occasionally use great wooden and slate vats open at the top. In Germany only large casks are used, holding 500 to 2,000 liters (132 to 528 gallons). In fact, the German system of fermentation admits of nothing else but casks. ^ These are uniformly closed to guard against the entrance of germ-laden air. Much has been said in the literature of the subject concerning the various kinds and sizes of vessels used for fermenting the cider. The size of the vessels is of the very greatest importance. Every maker whose work is worth}^ of commendation was observed to be using large vessels for ferment- ing the must. About 500 liters (132 gallons) was the smallest size recommended, and above this they ran to 6,000 liters (1,585 gallons). There are several reasons which have more or less weight in empha- sizing the necessity of having large vessels. One of the first is that a large ([uantity of must brought into a cask at proper temperature is much less subject to atmospheric changes and, hence, a safe, even fer- mentation can be carried on with greater certainty. There is also a very persistently repeated statement that the fermentation of the must in these large casks produces a marked effect upon (juality. It can be readily understood that the use of these very large vessels will pro- duce a considerable quantity of finished product of like character which can not be so well accomplished in small vessels. There will also be less dregs in proportion to the quantity of must if one employs 81 large vessels instead of small ones. The control of a large cask requires no more attention, and often not so much as a small one. FILLIXC; THE VESSELS. A convenient method of filling- the vessels plavs a voiy important part in handling the must. In many places this is accomplished by power pumps, which deliver the must to the receptacles placed in adjacent rooms or in another building. When the press room is over the fermentation room, filling is accomplished by gravity. Hose pipes are largely used for this work, but brass or copper must be used for all metal fittings. The less the must comes in contact with the air after it leaves the press the less liable it is to be contaminated with various undesiral)le organisms. The pumps and pipes used must be kept scrupulously clean. The height to which the cask is filled Avith must bears upon the method of fermentation to be employed. In England the old i)ractice of running the barrels or casks full so that they would "work them- selves clean" is still in use to some extent, as it is in this country, but all progressive makers in England and elsewhere have al)andoned this practice. Whatever modern sj'stem one may follow, the vessel is never filled so full that it will run over during the tumultuous fermen- tation. In the use of open vats the English almost invaria})ly fill within several inches or a foot of the top and skim the lees which rise one or more times, thus exposing the nuist to the air and also causing the lees to be mixed more or less through the liquid. In P^ngland no attempt was made, so far as observed by the writer, to control the exit of gas or entrance of air further than to prevent the entrance of insects ])v some sort of temporary covering. The French ferment almost universally in large casks or closed upright tanks, and it is rare indeed one sees an open vat. But when such vats are used, they permit the top lees to rest unbroken, forming a "head,'- the so-called "chapeau.'' over the liquor. In casks they usually leave a space of 8 inches to 1 foot below the l)ung unfilled. This permits the head to form without any overflow of lees. In Germany they invariably leave a space of from s to 12 inches below the bung unfilled, but with an entirely difl'erentend in view from that of the Frenchman. The latter makes nuich of the proper appearance of the "chapeau," or top lees, and it is an article of his faith that this cover shall not be broken or permitted to fall bat-k into the liquor. But the Germans, on the contrary, purposely preserve these lees from overflow and desire them to fall l)ack through the liquor and rest at the bottom of the cask. They argue that this secures inclusive fer- mentation, and utilizes all alcoholic material in the top lees which would be lost by skimming or by drawing the liquor away from the lees. 17217— No. 71—03 0 82 CONTROLLING THE EXIT AND ENTRANCE OF GASES. When fermentation occurs in the open vats, or ''keeves," natu- rally one can not control the contact of air with the surface of the must. But the French, by permitting- the top lees to rest, in a large measure guard the liquor from contact with the air. The reasons for thus guarding- the must do not appear to be recognized by English makers, but are quite generally considered in France, and ver}^ strictly so in Germany. If the must is fermented in closed vessels, it is a very simple matter to guard the entrance from germ-laden air by the use of simple devices such as are shown in the accompanying illustrations. In fio'ure ] 5 is shown a device which was found in use to some extent c5 Fig. 15. — Noel device for ventilating fermentation casks. in France, the character of which will be quite readily understood from the illustration. The metal base (a) screws into the cask and carries two connected glass chambers {h and c). The metal cap (d) unscrews to allow the entrance of liquid to the control chamber (c). When the cask is tilled to the proper height, the bunghole is securely closed, and this device is either screwed into a small central opening in the bung or into a hole in the cask near the bung. The liquid desired for puri- fying the air — either 8(» per cent alcohol or 10 per cent sulphuric acid — is poured into the chamber {c) until both glass chambers are about half full; then the apparatus is ready for operation. Should the pres- sure decrease in the cask by reason of falling temperature air can only enter by passing through this apparatus in a course contrary to the 83 arrows, and hence will be washed clear of oferms. On the increase of pressure through fermentation activit}' the o-as passes out at low pres- sure by depressing- the li(|uoi- in (/>) until it gains exit, as indicated by the arrows. This is the Xocl air controller; but in the writer's work it has proved entireh^ too complicated and too ditlicult to keep clean for practical use. The principle of air control is undoubtedly correct, but it is better accomplished b}' some of the following- devices: The German ••fermentation funnel" (tig. 16) is a sini])lc and far better device for controlling the air. This is a pottery or porcelain device having- a central tapering- stem (a) with a l)asin-like vessel (^ Fig. 16.— German earthenware ventilating funnel— vertical section. around its upper end. The central stem (r) rises nearly to the height of the outer rim, and is hollow. Over this hollow stem rests a remova- ble cap ((/). which extends to the bottom of the basin. The lower rim of this cap where it rests under the liquid is notched for the pas.sage of gases, as indicated by the arrows. This device is inserted in the bung-hole of the cask, and by reason of the tapering- stem can be made to tit quite tightly: but it is always better to use some parathn wax around it. The control liquid is placed in the outer basin until it is about one-third full: then the cap is put on and the device is ready for operation. While this is an awkward looking- device, it is the best 84 known to the writer for practical work. The large central opening- permits the operator to take the temperature of the must, or remove samples for examination at pleasure without displacing- the entire apparatus, and it can be quickly and perfectly cleaned. A third device (tig. 17), also of German origin, answers a good pur- pose, especialh" in laboratory work, but it is not recommended for cellar work. This is called the g-lycerin control tul)e. It is made of glass, and is operated by inserting- the stem through a ])ung {'/). Gh^- cerin or one of the liquids mentioned above is introduced at the fun- nel (h) until the bulb {d) is half full. The principle is exactly the same as with the previous devices. Should the pressure decrease in the vessel air can enter through the liquid b}' reason of the enlargements {d and ('). The enlargement (e) permits the escape of gas from the vessel without driving out the control liquid. A very simple device is shown in ligure 18. This con- sists simply of a bent tube in- serted in a perforated bung, the outer end being so placed that it rests below the surface of the liquid in a basin. This device is very faulty because if, for any reason, pressure decreases in the cask the liquor from the basin will be drawn into the must. In practice the best devices are found to be of the greatest assistance in indicating the activity of the fermentation. To the practiced operator they become at once the barometer which warns him of danger or assures him of the proper progress of fermentation. Fig. 17.— Glycerin ventilating funnel. VENTILATING BUNGS AND SPIGOTS FOR CASKS. In connection with the yu])ject of fermentation funnels, the use of a ventilating bung should be mentioned. After the first fermentation has subsided and the liquor has been placed in casks for the second fermentation, it is desirable to close the casks tightly — at least so as to exclude as far as possible the entrance of air. Yet in so doing one 85 can not be certain but that a .sufficiently strong fermentation may set in to spring- the staves or head of the cask. This misfortune is obvi- ated by using some sort of a safet}^ vent. The best simple vent for this purpose that was seen is the Noel vent bung (tig. 19). A central opening of sufficient size is cut a])out half way through this bung and then is continued at a diameter al>oiit one-half as great the rest of the way. On the shoulder thus formed a valve (a) is placed and held by the spiral spring seen in the cross Fig. 18.— Bent ventilating tube. section. The spring is supported above b\' a metal plate screwed over the opening in the top of the bung. The spring should be of sufficient strength to hold 2 to -i pounds of pressure, and the mech- anism of the valve and its seat should be so perfect as to prevent the ingress of air. If the bung is sterilized and driven tightly into place, it will insure proper ventilation of the barrel or cask and pro- tect the liquor ver}- well from the entrance of extraneous organisms. One of the most important considerations about the fermentation casks is the means of drawing off the liquor readily when this T becomes necessary". ]Many instances were seen in England and German v where the fermentation was carried on in barrels and casks which had but one opening, namely, the large bunghole; hence, in racking oti'. it was necessary to introduce a pipe at this opening, lower it to what was considered a proper position, and then siphon off the liquid. This method is extremely faulty, however, because of the disturbance of the top lees and the difficulty of determining the depth to which the tube should be lowered into the vessel so as not to take up the dregs. Every vessel used for fermenting the must should be furnished with a spigot so situated that it will draw off the liquor as near to the dregs a. Fig. 19.— Noel ventilating bung. 86 as can be safely accomplished without disturbing- them. If this spigot can be furnished at the outer end with a hose connection of proper size the liquor can be run directly to the cask designed for second fer- mentation in those buildings where successive cellar stories are used. In this case it is necessary to tit a glass Inilb into the hose so as to watch the condition of the liquor as it flows. If the must is transfer- red to vessels on the same level a pump is generallv used. The French makers commonly place spigots in all vessels employed for fer- mentation work. These enable them to note precisely the condition of the must without disturbing the lees. The large casks should also be uniformly fitted with manholes in order that they may be readily cleaned after use. THE CHARACTER OF THE MUST. On brino-ino- the must into the casks or vats for fermentation, it is of prime importance that the operator should know its composition as nearly as may be. To determine this accurately is the, work of a chemist, but at no factory visited was there evidence of the employ- ment of a chemist for this purpose. True, a number of the proprie- tors are themselves analysts. USE OF DENSIMETERS. Everywhere in Europe the makers use, with more or less care, some foi'm of must spindle or densimeter for estimating the sugar content of the juice. Those most commonly used are the ordinary specific gravity spindle, the Oechsle spindle (which, in fact, is the same thing with the first two figures on the left omitted), and the Beaume must spindle. The last is not a convenient form of spindle, as may be seen from Table XL Its degrees do not permit of ready comparison with other standards. It is the custom to take the density of the fresh must on one of these spindles and mark the result on the casks. Some makers keep a record of the casks by nuinber in a cellar book, and enter not only these data, but notes on the fruit used, the character of the fermentation as it progresses, and all subsequent readings of density and manipulations of the cider. Also the records of temperature of the must and cellar are kept. Without some such system intelligent control of the work is impossible. The following table gives a comparison of the readings of the three spindles mentioned, the proximate percentages of sugar at the diflerent densities, and the approximate percentage of alcohol which will result from its fermentation at each reading of the densimeter: 87 Table XI.— Readings of (liferent densimeters and approinmrite solids and sugar content, with the indicated percentage of alcohol after fermentatioit is coinj>leted.

To thi.s queiy the investig*atiou.s made have g-iven no answer, nor does the literature materially aid one. There have l)een pre.sented in some of the preceding- section.s man}- analy.se.s of apple mu.^^t made in different countries, and hundreds more could be quoted. These analy- ses differ wide!}- from the standards of the tables arranged bj' differ- ent authors to show the saccharine content of a fruit juice in comparison with specific gravit}'. Unfortunately, the methods and the instruments used are far from uniform in the various laboratories where these determinations have been made, and the chemists making them must necessarily vary in skill and precision; hence a mere inspection and comparison of these data do not lead to a true conclusion in regard to the composition of apple must. But this is the best that can be done at present, and the averages of the data previously presented are assembled in Table XII to serve our purpose in discussing the prob- able standard sugar content of a must: 88 Table XII. — Average composition of apple must for differ enf countries.

In fact a wide variation may be found in comparing differ- ent varieties of apples from the same orchard. This is a matter not 3^et properly investigated, but the existence of such variation must be conceded. Hence no strictly standard table of sugar contents in rela- tion to specific gravity is possible. Careful inspection of the published tables on specific gravitj" and relative sugar content, and a study of the actual analyses of apple must available, lead one to believe that the theoretical sugar content usually given is too high. In Table No. XI, there is given for com- parison the approximate sugar content which, in the writer's opinion, is likely to be found in normal apple must at the different densities indicated. True, the sugar percentages adopted in this table are empir- ical, but they are such probable averages within a small percentage of error that they are used to construct a table (No. XIII) to be used as a cellar guide in fermenting cider. This table appears to serve a very definite purpose, first, as a guide in the technique of fermentation, and, second, to assist in some measure in elucidating the further discussion. Table No. XI aids the manipulator of the must to estimate with con- siderable accuracy the sugar in the fresh must, and Table No. XIII assists him in watching intelligently the progress of fermentation. Thus, by the latter table, he is able to ascertain quickly the approxi- mate quantities of sugar and alcohol in a fermenting must of known original density. Attention was called to the presentation of these data in this form by the work of Mr. F. J. Lloyd, consulting chemist on cider experi- ments of the Bath and West of England Society. The work done under his direction on cellar records and technique was observed care- full}', and the ideas presented in his table and remarks in the journal of the above societ}' for 1896 (pp. 139-164) are considered as very important. The same may be said of his other papers. The writer was ^ot able, however, to adopt the figures of ]\Ir.

But b}" a study of the principle involved in this table, and l)v comparison with standard tables on spe- cific gravity and relative sugar content, and the actual analyses, Table No. XIII has been constructed. By it an operator may determine at any reading, between l.O-iO and 1.070 on a standard hydrometer, the probable sugar content present, and the approximate alcoholic strength of the liquor. Thus he is enabled to know how the fermen- tation is progressing. As a cellar guide this will be a very important help, and by reference to it the later discussion on the manipulation of the must will be more intelligible. As a basis for this table it was assumed that a must reading 1.040 specific gravity, contains 8 per cent of sugar. Kramer savs 9 per cent, but this is surely too high for apples. Power says 8.9 per cent, which is also too high, at least for American fruit. Kramer's table then allows 1 per cent increase in sugar for each 5 points (0.005) on the hydrom- eter, but this if logically carried out requires that the nonsaccharine solids increase proportionally more rapidly than the saccharine sub- stances. Analytical data are against this theory; hence, it has been estimated that the sugars increase 1,05 per cent for the first 5 points above l.olO, and be3^ond that at an increasing ratio found b}^ adding an additional 0.05 per cent of sugar for each subsequent 5 points (0.005) on the hydrometer. But turning to the subject of relative decrease in sugar content below 1.040 it becomes necessary to allow a loss of 1 per cent for each 0.005 on the hydrometer in order to exhaust the 8 per cent of sugar at unity — I.OOO on the hydrometer. Yet, as there are solids other than sugar present, it is altogether improbable that this will show the true percentages if the liquid is considered to be water; but it really con- sists of a mixture of two liquids, water which constitutes much the greater part, and alcohol which is lighter than water and which enters into the mixture in a constantl}^ increasing proportion as fermentation progresses. Hence, for a must originally showing 8 per cent of sugar, it is probable that unit}' (1.000 on the hydrometer) will about In'ing it to drj^ness;" but by the same reasoning richer musts will not come to entire dryness at unity. This the table shows when carried out on the principle that for each 1 per cent of sugar lost, 0.5 per cent of alcohol is formed. This ratio of alcohol for fermentable sugars is onl}' approximately correct. In using this table as a cellar guide, one notes in the left hand col- umn the hydrometer reading corresponding with the original density recorded for the must, and then finds in the box heads the present reading of the h^^drometer; the figures for sugar and alcohol percent- ages at the intersection of the lines from these two readings will show approximately the present condition of the nnist as to alcohol and sugar content. « In the technical phrase of fermentation work " dryness " means total absence of sugar. 91 FORTIFYINC; THE MUST. In this connection a few observations on the subject of fortifying the must will be apposite. This practice was not ol)served either in England or German}'. Doul)tless it may be done in these countries, especially in case-of perry (pear cider), })ut it did not seem to bo a part of the regular system of cider making. In France, on the con- trary, sugaring up the weak must obtained from second pressing seems to be an important ptirt of the business, and is so reguhuly practiced that the government makes a special rebate of the sugar tax on sugar so used. The government agents, however, verv carefully see to it that all sugar withdrawn from bond for this purpose is denaturalized by addition of must, so that it can not possibh' be resold in the markets. For 1898 (the figures for that year being the latest obtained) the government officers reported 188,760 pounds of sugar withdrawn for cidK3r making, and 80,262,771 pounds withdrawn for sugaring wines. An apple must reading 1.010 on a standard hydrometer can. if prop- erly handled, be made to prodmce a cider approximating -1 per cent of alcohol, but it will ])e rare indeed that this result will actually be reached in practice. Hence it appears that a nmst reading at that figure is about the minimum in quality which can be properly emploved for cider without fortifying, and this grade should be used only to prepare a cider for local consumption. This is not because a high percentage of alcohol is so desirable, but ])ecause it is not desirable to push the fermentation of a cider to the limit where there is no sac- charine substance left for the j^east to subsist upon, that is, until the liquor is absolutely "dr3^" If the cider is properly handled, the 5^east will not entirely cease to be active for several years after bottling. This activity is of the greatest value in preserving the bouquet of the cider and keeping it sound. But if it is desired to produce a stronger cider from a low- grade must, reading approximately 1.040. one can add about 3 ounces of crystallized sugar per gallon for each 1 per cent of alcohol desired in addition to the normal (juantity resulting from fermenting the natural must. This, howev.er, denaturalizes the cider, and should not be resorted to in excess of 1 per cent increase of alcohol. The French say the sugar should be inverted before using, but this seems doubtful, as the j^east will accomplish this itself, and probably the sugar will be consumed more slowly. STERILIZING THE MUST BY HEAT. This process is mentioned only to condemn it so far as cider making is concerned. Not a sino-le maker worthv of credence in the factories visited abroad recommends or uses this method. It has been suggested as a means of controlling the initial fermentation, because, after ster- 92 ilizing ]\v heat, one can sow yeasts into the must as desired, and thus bring- about a fermentation at will, but the cooked taste contributed to the must by heating- is difficult if not impossible to overcome. Heating or pasteurizing to check fermentation or insure keeping of cider is also just as faulty, and is never necessary in a properly man- aged cellar, unless one desires to preserve a partially fermented cider. For this purpose pasteurization at 60 to 70^ C. is practicable with goods which have sufficiently fermented in bottles to become sparkling. THE USE OF SPECIAL YEASTS. Having brought the fresh must into the casks or vats for fermenta- tion, the modern cider maker has to consider not only the temperature of the must and of the room and the various other conditions already discussed, but also another question of very great importance: Shall the fermentation be left to the organisms normally present on the fruit and those which may at the time of grinding and pressing enter the must from contact with the air, the machinery, and the vessels? Every cider maker knows that under proper temperature conditions fermentation will quickly ensue after the juice has been placed in a receptacle. But the operator untrained in the scientific phases of this subject may not know how readily numerous undesirable organisms gain access to the fruit juice. These objectionable organisms are sure to be present upon the fruit, and especiall}^ so if unclean and unsound fruit is used. Or they may be present in parts of the machinery, especially if any parts have been left vmcleaned after previous usage; and, what is perhaps still more important, these organisms may be present in great number in unclean barrels, casks, or other vessels. The numerous organisms (microscopic plants), both useful and harm- ful, which grow readily in fruit must can not be discussed here. Suffice it to sa}' that the quality of the resultant product de])ends ujpon whether desirahle or undesirable orroniptly. AVith larger quantities of must, one should take a proportionally larger quantity of the fer- menting culture first made. For large establishments, a culture of 50 or 100 gallons can be first made by boil- ing the necessary must, putting it while hot into a perfectly clean but unsulphureut 45- F, can be reached, and at this temperature the yeasts work properly, and man}' disturbing organisms, as, for example, the vinegar ferment Bacterium aceti^ are quite reduced to dor- mancy. If the temperature can be gradually reduced to 40° F. as the cider reaches maturity, its safety from mal-fermentation is thereby well insured, because the organisms concerned in diseases of cider do not thrive well at this low temperature. SECOND RACKING OFF. If the must has fermented in an orderly manner and l)een drawn off as outlined above, no second racking is required until the fermenta- tion is practically completed. But if a troubled fermentation follows the first racking off', then the cider must be very carefuUj^ watched and the temperature kept from rising above the limits mentioned. It will be well to use under these circumstances some means of "fining" or clarifying the cider so as to produce entire subsidence of the parti- cles held in suspension in order that a second racking- off ma}' occur as soon as possible. The cider must be freed from the lees and as far as possible from all)uminous matters, or it can not progress properly to the completion of its period of fermentation. Much prejudice exists abroad against the use of animal substances, as gelatin, white of Qgg^ and the like, for fining cider. The French use quite freely preparations of the bark of certain species of oak. But as the active principle in these is the tannin, it would seem better to use the commercial tannin itself. Our American fruit is so weak in tannin that the addition of this substanct^ will doubtless be found 101 advantag-eous, as it appears to steady the tendenc}" to too rapid fer- mentation and total destruction of the sug-ar; and, V)est of all, it helps to coagulate the allnmiinous matters, and thus to precipitate them, carrying down at the same time other matter held in suspension. The dose of tannin should be about one-half a gram per gallon accord- ing to French standards, but our fruit may require more for the best results. This may ver\' properly be added as soon as the must is inui into the vessels for the first fermentation, but it is mentioned here especially as a remedy when a second troubled fermentation sets in. Stir the amount of tannin needed for a cask into a small (juantity c)f cider and then add to the cask, and agitate by inserting a clean strip of wood and stirring- the cider thoroughlv. After treat nig a cask in this manner watch it carefully and rack ofi' just as scjon as the cider becomes limpid. The cider will, during this period of disturbance, have fallen in specific gravity. This should be carefully noted, and the liquor should be transferred as quickly and quietly as possibly into a cask suitable for the still fermentation. The second racking off, when it occurs in normal process of fermen- tation, is usually accomplished from three to five months after the first, and the liquor should then have cleared out bright and fine, with l)eau- tiful color, and have begun to form the bouquet of finished cider. The specific g'ravity will vary from 1.001 to 1.008, and the cider is now ready to go into the casks designed for transportation or into bottles. The English bottle at much higher specific gravity, ))ut this would undoubtedly be a wrong practice in our climate. The racking into these final receptacles should be accomplished with the utmost care to guard the liquor from contamination, and, if possible, the work should be done in cool, bright weather with high ])ar()meter, l)ecaus(^ climatic conditions affect the stillness of the liquor in the casks. When ready the cider can be put in barrels or casks to suit the needs of the trade, but these must be cleaned in the most careful manner; and, in order to secure the cider from the effect of air, the outer surface of the casks should be carefully scraped to expose the fresh grain of the wood and then treated to a coat of hot tallow. This, if well applied, will render them quite impervious to air, and thus practically seal up the cider. The modern paraffin-coated barrels would answer well for this purpose. The utmost care should be observed to use perfect bungs. There must be no seepage, and cloths nuist not l)e used around the bungs, for these will be constantly moist, and thus furnish a direct conduit for vinegar germs to enter the cider. The bungs may be verj' properly dipped in l)oiling tallow or paraffin before use. If the cider is bottled, this should be accomplished with the utmost care, taking pains to conserve the carbon dioxid in the cider, and not to permit it to come in contact with the air. The corks used should be the best champagne corks and may be dipped in 50 per cent alcohol just as used. This will free them of germs. The}' should be inserted 102 with a reo-ular corking machine. The bottles should be left standing upright for a few days until the liquor is quiet, and may then be laid on the side. LAGER FERMENTATION. Whether in casks or bottles, the cider is now left in the storage room to ripen. This is called b}" the Germans "lager fermentation." The temperature should be kept as near -iO'^ F. as possible, and the vessels (casks or bottles) should remain undisturbed. The cider will soon be- come sparkling, and in two to four months will be in condition for use. If racked into these final receptacles at the density mentioned, the air being carefully excluded, the result will be a cider which will, in a measure, chanipagnize itself, and retain some sugar for a long time; but if left in casks with the wood pores open, the cider will eventually become quite "dry" (free from sugar), the gas will gradually be lost, and the product will be a still, hard cider. This sort of cider is little relished l)v most people, and unless preserved by some chemical reagent or charged with carbonic-acid gas at intervals, it will be turned to vinegar whenever temperature conditions favor the growth of the vinegar ferment. GERMAN METHOD OF FERMENTATION. As already stated, the German makers pay no attention to the forma- tion of head or top lees, and make no effort to draw the cider from between the lees. Their cider is, therefore, different in character from English, French, or American cider. Their method of treating the must doubtless accounts, at least in part, for this difference. The fresh must is run into the fermentation cask until it comes within about 12 inches of the bung, and then, if yeasts are used, these are sown at once, using about one part of the strong culture, hereto- fore mentioned, to 100 parts of must. A ventilating funnel is now fitted tightly into the bunghole, a 5 per cent solution of sulphuric acid being used in it to prevent the entrance of organisms from the air. Fermentation progresses under the methods above discussed, but nothing is done to the liquor until it has fermented out nearl}^ to dry- ness and becomes still. The top lees are permitted to fall back through the liquor and settle to the bottom along with the 3'easts. When the liquor is quite still, some makers follow the practice of fflling the cask to the bung with cider, so as to avoid having an air space, and then closing the bunghole sufficiently tight to prevent access of air. Bung- ing at this period is dangerous, unless a vent is provided for b}' means of a ventilating bung. There seems to l)e little uniformity of practice among the Germans about racking off'. Some racked as early as December, and then again about March, while others racked off' three or four months after put- ting the must in casks, and then again the next autumn, if the liquor 103 was not bright at first racking. Many makers filtered at first racking- and put the cider down in casks to await hottliijg or preparation for transport in other vessels. The writer invariably found the ordinary finished German ciders poor in color and flat in taste to the American i)alate. They partake of the character of very light still wines, devoid of the piquancy and astringent character ordinarily expected in ciders. This does not alter the statement heretofore made that German makers produce a standard article of rather more definite character than those produced in the other countries visited, and the}^ champagnize their ciders in a quite perfect manner. PRESERVING CIDER IN STORAGE. In the German cellars great care is taken to sulphur and double sul- phur the casks, esiDecially as the cider is drawn from one to another in Fig. 20. — Device for maintaining- covering layer of carbon dloxid as cider is withdra\vn. a nearly ''drj^" condition. They also resort largely to the employ- ment of carbonic acid gas as a preservative. This is applied from cylinders of carbon dioxid either to barrels to fill up the vacant space as the cider is drawn (fig. 20), or to charge the cider in storage (fig. 21). A cylinder of this kind may be attached to several casks at once so that the overflow of gas from the first goes to the second, and so on. As soon as the first cask is sulHcienth' charged, it is disconnected and tightly bunged, and the operation is continued by adding other casks to the circuit and dropping ofl' those charged until the work is com- pleted. The bungs used while charging with gas are double per- 104 forated. as shown, and glass tubes, with small rul)ber hose connections, are used to convey the gas from the cylinder to the casks. The device 4;^^-^^^^'^ -^^ Fig. 21.— Devise for charging casks with carbon dioxid m storage cellar. at the bottom is a 4-way rubl)er cross which admits of using four .short distributing pipes in the liquor. As this joint is made with ruV)ber connections, it is j^erfectly flexible and can easily be inserted and removed from the casks. The device shown in flgure 22 is used to sulphur the casks. This may be used when cleaning barrels to destroy fungous organisms, but it is chiefly used abroad to sul- phur the casks just before running the liquor into them, botli at first and second fermentation. Thorough sul- phuring will largely destroy the vegetable organisms which ma}' be present in the casks. If they are not after- wards rinsed carefully, too much sulphur may remain in the casks so that the after fermentation will l)e hindered and a taste of sulphur may even be contrilnited to the cider. Perfectly clean water should be used for rinsing. The sulphur match is placed in the cup, then lijfhted, and is lowered burning into the cask until the tapering- bung closes the opening. It will burn until the oxygen is exhausted, when it should be removed. By this device none of the sulphur is permitted to fall into the cask. FILTERING OR CLARIFYING THE CIDER. The l)est English and French makers agree in the statement that filtering of ciders is a very laborious and unsatisfactory process, resulting usually in loss of quality to the product. The Germans, on the contrary, are more favorable to the filter. Filtering cider appears to be a process much more difficult, ordinarily, than filtering wine made from grapes, and should be avoided if pos- sible. The reason for this is the presence of mucilaginous substances in the liquor. However, unless a cider can b(^ i-ack(Hl (putc free from Fig. 22.— Device for burning sul- phur match in casks. 105 the lees at the first racking-, or at most a second racking-, there is sure to be difficulty in securing- a bright product unless the filter or some other method of clarifying- is resorted to. The use of tannin to assist in clarifying- ciders has already been mentioned. Filters of various types are in conmion use in the different countries visited, some being very primitive, while others are the best up-to- date appliances seen. The hag filter.— Oi primitive filters, the most simple was a device in form much like the insect nets used by entomologists to catch but- terflies (fig. 23). The cloth used was linen, of such a texture as to thoroughly strain the finest particles out of the cider. It is sometimes called forfar. These conical bags are about a foot in dianicter at the Fin. 23.— Linen sack gra%'ity filter. larger end and taper to a point, the length being about 18 to 30 inches. They were used in considerable numbers, supported on a rack over a vat, as indicated. The flow through these bags is slow, and the cider is so much exposed to the air that if there is any tendency to mal- fermentation this process must surely increase the troul)le. The cloths need frequent washing to clear them of lees, but should not be treated with hot water. This device was in use in both small and large factories in England, sometimes with fresh must, but usually when racking the first time. It is not commended for use in America. Tuh filter. — The best simple device seen was a large tub or vat with a finely perforated false bottom, supported several inches above the true bottom, the space between l)oing packed with wood pulp which 106 served to strain or filter the cider almost perfectly. This was observed ill an English factory where the must was fermented in open " keeves," the head being- skimmed oil' until active fermentation had sul)sided, and the product being then run through this iilter and put into casks for ripening. This apparatus does good work, hut the cider is much exposed to the air. Tlie cellvJoge pov^er filter. — Some of the English makers have come to use the German filter shown in ligurc 21. This is made by Otto Fromme at Frankfort, and is the liest device observed. It is, how- ever, costly, and a force pump is required to di-ive the liquid through the filter, or the liquid must be drawn from some height in order to give the necessary pressure. This is also a wood pulp or cellulose filter. The pulp is arranged between perforated disks, and the machine permits of dismounting and washing the parts and the pulp at will. In some English factories attempts were made to filter Fig. 24. — Cellulose power filter used in Germany. the fresh juice with this machine, but this generally resulted in fail- ure, and besides was very wearing on the apparatus. Fresh apple must is very difficult to filter because of the pectose or mucilaginous substances it contains. The use of any of the above filters does not appear to l^e practicable except when the must has been fairly well fermented, and has freed itself in this manner of a large part of the parench3'matous tissues and albuminous matters present therein. Ashestos md' fiJter. — The French use a filter (fig. 25) which they claim will remove all insoluble matters from the fresh must, and leave it clear and limpid as it goes into the cask. No demonstration of this was seen, ]>ut this filter (Filtre Maignen) is much used in France, and appears to be a good, cheap filter. It is made from asbestos. A fairly closely woven asbestos sack, 10 or 12 inches in diameter and of anv desired length, is tied tightlv at one end; tluMi in tlie bottom of this is placed an openwork disk, and a string is tied al)ove the same so as to nearly draw the sides of the sack together; a))ove this is placed a second disk; and so on until the filter sack is filled. The open end 107 of the sack is then tied tiohtlv amund a niotal tittiiii'- which connects with a nil)])er pipe, and to tiiis pipe a pump is attached. The filter is placed in the tul) or vat as shown (tig-. 25), and the suction of the pump draws the must through the parts of the asbestos sack and disks, largel}^ freeing- the same from floating- particles of whatever nature. In some styles of this device a second asbestos sack of coarser weave is drawn over this accordion-like device, and serves to still further assist in straining- the li(iuor. Possibly when the cidci- is di-awn into an open tul) at racking- ofl', and this filter is carefully used, the li(juor can be filtered bright. This stvle of filter is readilv cleansed, it onlv beino- necessarv to untie the sack, remove the disks, and Avash all the pieces carefully. Saltwater, used warm, is said to accomplish this nuich l>etter than fresh water. Filters of this pattern may be connected up in sets on Fig. 25. — Asbestos sack filter — "Filtre maignen." a main pipe, or on a central disk of metal, and the capacity may be thus g-reatly increased. It should be added that all metal part.s of connections, pipes, pumps, etc., mu.st be of brass, or other material which will not be attacked ])y acids. German ashestos jilter. — The Germans use chiefly but two Alters, viz, the one made by Fronnne (shown at flgure '2-^) and another small aft'air (flg. 26). The latter is an as])estos Alter, but works solely bv g-ravity , as indicated. A self-regulating (/>) valve governs the inflow at the top, hence it can be set to work on a cask and left to itself until the receptacle into which the filtrate runs is filled. This device is of small capacity, but does good work. The cylinder is packed with asbestos which can be removed, washed, and re-used. Both of these German filters are constructed with the idea of pro- tecting- the cider from the air, as it is in nowise exposed by their use except when it is delivered into the cask. This is a point of much 108 importance, especially among the Germans, as their cider is fermented nearly to dryness before tiltering-, and hence is less able to protect itself by the regeneration of abundant carbonic acid gas. For this reason the Germans advocate charging the casks with carbonic acid gas before running th^ cider into them. Fig. 26.— Asbestos gravity filter. THE CHEMICAL COMPOSITION OF CIDER. It will doubtless be clear to every one who has manufactured ciders, or followed the foregoing discussion, that it is not possil)le to iix upon a certain chemical composition and sav this represents what should be considered a standard cider. Chemical analyses, however, reveal what it is exceedingly important to know, viz, the sugar, alcohol, and acid contents, with other data of possibly less importance. Without these data one is completely in the dark as to whether the product has been properly or improperly fermented, and no technical progress in the study of methods is possible. Chemical analyses rightly interpreted will also aid the consumer in distinguishing pure from sophisticated ciders. 109 The complete study of this subject is yet to be undertaken, but rep- resentative samples of ciders were collected l)y the writer in the dif- ent countries visited and forwarded to the Bureau of Chemistry, United States Department of Agriculture, for analysis. To those samples have been added a num])er of typical, sampk's of American ciders collected during the 3'ear 19ol. The analyses of these ciders, with explanatory remarks, are given in the tal)les which follow: Table XIV. — Coinpoxition of ciderii: Anahj^en of Fvendi miiiple-'< hi/ Bureau of Chenrntry, United States Department of Agriculture, 1901.

A very dry sparkling cider' "Samples of cider made at Virginia Agricultural Experiment Station; analyses made by Professor Davidson. Discussion of these tables is hardly necessaiT further than to call attention to salient facts relating to the specilic gravity, alcohol, and sugar content. The French and German ciders are remarkably alike in regard to specilic gravity and the indications are that these ciders are fermented practically' dry. The analyses show this to be the case. There are two German samples — Nos. T and 12 — with comparatively high specific gravity, and these show a considerable percentage of sugar still unfermented, in fact a very much larger percentage than is necessary to produce the desired result, namely, to champagnize the cider. The French cider, No, 4<). is a champagne cider with a much smaller sugar content. It is a question of the taste of one's customers whether such highly sugared champagne ciders as these two German samples should be made. In the writer's opinion the French sample is better; and it has been detinitely proved at Blacksburg that a tine gaseous or champagne cider can be made without the addition of sugar. The French samples are strikingly high in volatile acids, which would indicate the presence of acetic acid. The cellar methods may account for this. The two analyses ofiven at the bottom of the table of American sam- pies are ciders made at the experiment station at Blacksburg, Va, Both were prepared from samples of the same must, handled side by 113 side, until tinished. Each was sown with a culture of pure yeast, the one a yeast isolated from a French Sauterne wiiio. the other from u Normandy cider of the Vallec d'Auoe district. Tiie first resulted in a fine cider of beautiful color, o-aseous, and with flavor like cham- pagne, the other in a very tine, dry cider, sparkling and gaseous. Sugaring ciders for champagnizing is a doubtful practice, and the best-posted makers abroad insist that the true future of cider making lies along the line of fully fermented dr}' ciders. The analyses of English ciders show wide variations in their compo- sition. The samples Nos. 22 to 31 and 55 to (31, inclusive, were taken at the Bath and West Show, the first set in lUOii and the second in 1901. Both sets of samples reveal similar characteristics — high specific gravity and in the main low alcohol and high sugar content. These are simply incompletel}^ fermented ciders, either filtered as clear as possible of yeasts and held in highly sulphured casks, or treated with chemicals to check fermentation. Nos. 82 to 39 are samples taken at factories, as revealed by the notes, and are among the very best ciders collected, and show the possibilities of English cider fruits. WORKS OF REFERENCE. As mentioned previously in the discussion, the Frencli literature on cider making is very voluminous, but it can not be said that it is all of great value. In fact there is an enormous literature on every phase of the subject, expressing everjj^ shade of opinion, so that one is at great loss what to commend. Consequently there is given in the subjoined list only a few references, and these are to those sources which were found to be most useful and reliable. The first work is now out of print and can rarely be found. The others are mostly easy to obtain. Of the German literature it must be said that it is not al)andant nor very rich in actual observations made on growing the fruit and making the cider, nor in technical investigations of a diemical nature or other- wise. The books pi'esented in the list are mostly compilations l)y persons more or less familiar with the actual practice of cider or wine making. The recent English literature is practically all found in the Journal of the Bath and West of England Society and the other two works named. There is an older English literature on the sul)ject. which is practicalh' inaccessible. FRENCH WORKS. L. de Boutteville ot A. Ilanchecorne. Le Cidre.
