VOL. XVIH. INDIANAPOLIS, IND., SATUBDAY, DEC. 15,1883. NO. 51. -/* 4 ?> BUTTEK, CHEESE AND EUGS. Eleventh Annual ConTcntlon of the >*a- tlonal Association. The eleventh annual meeting of the National Butter, Cheese and Egg Association took place at Cincinnati on Tuesday, Wednesday and Thursday of last week, the attendance being full nnd the Interest taken very great. Attending members, were hospitablyentertained by the people of Cincinnati, and the meeting'was every way pleasant and successful. The three days were fully occupied by spec Chen and discussions, of which we can mention only the most prominent. ■The flrst morning's session was devoted Chiefly to a discussion of the Imitation butter question. J. W. Johnson, of Iowa, read a paper on "The Situation," in which he dwelt particularly on the various counterfeits and •hams that detraud the honest butter maker. He stated, however, that legislation upon oleomargarine should go no further than to require the makers of It and those who sell lt or serve lt upon publio tables to announce lt as such and Its Ingredients. Tbls wonld place the goods squarely upon their merits. He claimed that the trade ls on the Increase, and that one factory manufactures as mocha1.2!y. 000 pounds per day. It has damaged dairy exporting, for lt has substituted renulne but. ter In some measure, and driven foreign customers elsewhere. "The American butter product must be Increased In quantity. Improved In quality and sold at reasonable prices. We must organize, we must economize, we must centralize the forceseniployed In this great work. The capital, the labor- all should he reduced to tbe best possible working condition. Co-operative dairying ls a means to tbls end." Mr. J. gave an explanation of processes of the two kinds of creameries— the full milk and gathered cream. He considered the gathered cream system better adapted to newly settled sections, and the full milk to thickly settled farming sections of country. In the talk following the paper.lt was stated tbat large factories were run for the purpose of supplying oleomargarine manufacturers with oil, and that even sotne creameries used the oil; mixed and churned with the cream. In the making of creamery butter. Buch creameries, however, are not of' the Tellable sort and are largely In tbe minority. l'rof. I.. B. Arnold, of Rochester, N. V , read the first paper Wednesday morning, on the subject "Cheese and Cheese Making." He thought that from fifty per cent, of the milk of the couutry butter waamade, while only five per cent, was given to cheese. Yet the cheese product was prominent In commerce because lt waamade almost exclusively in factories and waa distributed here and in Ku- rope through tbls means. Oue pound of pure, perfect cheese equals two pounds of meat In nutriment, yet tbe selling price of each is about equal per pound, because our cheese product Is below the standard, from Imperfect methods In making and curing. The fact ls we do not know how to make good cheese. Milk may be divided lntocream and skimmed milk. The cream then Into butter and butter-milk. The butter Is then divisible Into some eight different oils. The buttermilk may be divided Into whey and coagulated matter, aud so with skimmed milk. Not only these constituent elements, but -various foreign substances get In the milk. From stagnant water or unwholesome food JVlclons Influences are encountered. Filth lo any regard in handling the milk Introduces weakness, while uuhealthful conditions of the cow's glands, from too high feeding or other abnormal conditions, render the art difficult and the article not fine. Mr. H. B. Ourler, of Illinois, read a paper about practical dairying and creameries. There was a division of opinion as to the better kind of creamery, one for gathered cream or for full milk. Mr. "Hurler was rather inclined to the full milk creamery, but there wero many considerations that made the keeping of the milk ou the farm a profitable advantage. Mr. C. K. Dexter, of Chicago, read an able and Instructive paper on the "Commercial Uelatlons to the Producer," He explained tho reason of the higher uniform price of creamery butter, and the necessarily varying price of dairy butter, although he claimed that the best butter could be made at a dairy of selected cows. Hesaldthat the Impression that a ring had been formed to keep up the price of creamery butter was a mistaken one. He deprecated the mlsuseof the term factory, and gave as part of hlsadvlco that creameries would do well to brand tbelr goods with the name of the company or owner rather than a fancy title, and told how a manufacturer of butterlno had adopted the name of a brand of creamery whose owner was proud of his products. The last morning session of the convention waa devoted to the read! ug of a table of statu! leg, showing the receipts and values of butter, eggs, poultry and cheese received In New York for the year ending November 80, 1863, aa follows: Butter—Eastern, 41,801,060 pounds, value 26 cents per pound; Western, 45,743,860 ponnds, value24cents.,perpound.

Total value of butter, cheese, eggs and poultry received in New York during tbe year, 851,584_'!8S 08. Exports of butter and cheese during the year-Butter, 18,416,003 pounds, valued at 26 cents per pound; cheese, tT7,779,5!iS pounds, valued at llj; cents per pound, an: excess in the amount of clieescexported over tbat of the previous year of 10,309,554 pounds, and In butter of 11,11.5,117 pounds. The highest price of WesteriT>extra creamery butter was 41 and the lowest 21 cents. •* P^of., Henry E. Alvord, of New York, addressed the assembly. He said that it was now a question of moment what should be done with the surplus milk. Dairy products are now converted into milk, butter and cheese. The supplying of milk to cities even within a radius of 250 miles, was overdone; In catering to high-priced buyers milk and cream in bottles for family use was now introduced, but the demand was necessarily small. Prof. Alvord thought It abetter plan to create at market for skimmed milk. Boston has such a market, but New York unjustly cuts off by legislation what, lf proper managed, would be placed on the market at a price that would permit the poorest to have a flne, nutritious article of diet—skimmed mllit; then lt becomes necessary for Eastern dairymen to fall back on cheese as their best hope for home consumption. One drawback to the Increase of the sale of American cheese Is Its generally large size, which compels a large waste to the retail dealer. A cheese that could be sold to families Intact would be a great advantage. Those weighing from four to eight pounds are now becoming sought for by the trade. Colonel Coleman, of St. Louis, gave directions formaklng hens lay during .winter. With young hens kept in warm, comfortable winter sleeping quarters, liberally fed, and -with an allowance of animal food, either of scraps from the table or from the butcher's, no one wonld have difficulty in having the hens lay eggs all winter. He further advised plentiful coats of whitewash and kerosene ell about the quarters, to keep off vermin. lied pepper at times given to the chickens, movable henneries and prompt treatment by banishment or cutting olTthe headatthe flrst approach of disease among the chickens. The old officers were re-elected for tbe ensuing year, Jno. J. McDonald, president, and Col. Robt. M. Littler, secretary. After election of officers the convention adjourned.

All plants are divided iuto two great groups depending on their reproductlon.those which reproduce by seeds and those which reproduce by spores. In the latter division the ferns are the highest, then, the mosses, and so on down past fungi to forms so simple that they consist of but one cell, and so mluute that lt tak^s the highest powers of the microscope to study them. In tho seed group we And our pines and spruces the lowest members, next above them probably the grasses and sedges, and so on past lilies, crowfoots and mints to the highest of all plants, the great family of composites, to which belong the sunflowers, asters and golden-rods. It should bea,remem- bered though that seeds and spores are by no mean**-4lflerent things In character, but In the degree Of. thett development.-Aspore holds kUmu ths same relation to the pluntlet In Huej-'d tuat an egg does to a new-born calf. Tue calf was once bothing but an egg, but developed beyond that condition while In connection with the mother, while the hen's egg develops beyond that condition outside of the mother's body. Ho every plantlet in a seed begins with what we might call the egg-cell, but lt develops while In connection with the body of the parent until lt becomes that complex thing we call an embryo, while the spore ls that original egg-cell turned loose to care for Itself. In short then,spore and seed.eggand calf, differ not in their nature but In the time of their blnh. The great mistake. Is yet often made by students of botany that they study only seed-bearing plants and think they have' exhausted the study, when in reality the great majority of plants produce spores. The reason of course Is that the seed-bearing plants are tbe largest and hence boat known, and our study bad better begin with tbem. We sball begin where the plant begins and study first the structure of tbe seed. I.—WHAT CAN BE SEE**: WITH THE KAKED EYK. It a plump apple seed be split with a sharp knife from base to point at right angles with the flattened sides, something like figure 1 will be seen on the cut face. With tbe help of a pin lt will then be seen that there are on the outside of tho seed two coats, the outer one very much hardened and dark, the Inner one very thin and whitish. These two coals cover everything within completely, except at one point, aud In the apple seed this unprotected spot is Just at tbe point. It ls a very* important spot, for through lt Is to come the water to make the seed sprout. If the points of apple seeds be dipped into melted sealing-wax or bees-wax tbey cannot be made to sprout, for no water can get through the unprotected spot left by the two coats. And so any kind of seed can be kept from sprouting If its weak spot can be dls covered and made Water tight. The whole mass within the two coats is called the nucleus or kernel, and a sharp look will easily detect all of Its parts tn our split apple seed. From the blunt end of the Beed nearly to the point the nucleus seems split In two, (Fig. 1), these two halves being tbe seed leaves or cotyledons. Below these are seen to come together and form a short round stem, which is really the first stem of the plant, and is known as the seed-stem or caullcle. This was formerly called the radicle, because it waa supposed to be the first root of the plant, but lt ls now Fl«. 1. fi«. a. known that no part of the root is ever found in the seed;lt simply grows from the lower end of the stem after tbe young plantlet haa left the seed. On tbe top of this caullcle, where the cotyledons come together, ls seen a small conical bud, which contains one or more Joints of the stem and leaves which are '. to expand in the air. This ls known as tbo seed-bud or plumule. Tbe cotyledons, caullcle, and plumule taken together form the embryo. It will at once be seen that In our apple Beed the embryo and nucleus are the same thing, or In otber words, that the embryo flIlsupaUtbe space within the coats. The reason of this ls that the food for the young plantlet ls stored in the cotyledons and they have become so stuffed with lt as to fill the whole space. In the case of seeds like those of tho potato (Klg. 2), however, it will at once be seen that nucleus and embryo do not mean the same thing, for the food is packed all around the embryo. The nucleus then is the food and embryo taken together, and there are two ways of storing the food, either around the embryo or within Its cotyledons. The seed-bearing plants are divided into two great groups depending on tbe number of the cotyledons, there being either two, as in the cases we have examined, or one, as in the mis?, urates, eto. I,f a grain of corn be ex: • aralned, oisj embryo will be found In.the center, near one side, as a kind of core, surrounded by a great abundance of food material, but there Is but one cotyledon, and thlsls rolled about the bud,.Fig. 3, which .is the plumule, aud this plumule Is nothing but ' a series of minute leaves wrapped about each other. To sum np then, we find the seed made up of two coats containing a nucleus, which is made up of food material stored outside or within the embryo, and this is made up of one or two cotyledons, a caulicte, and a. plumule. Fie. 3. ir.—tvn_Ti—■_ MiCRoscorK snotvs. The microscope simply shows that all parts of the seed are made up of cells, which, in general, look like the cells of a honey-comb, though not always so angnlar, and these cells are all full. Here then comes a point of great Interest, for we are looking into the workshops of the seed and can see iu tools and Us materials. Every cell seems to be about a repetition of every other cell, and we find the tools In use reduced to but one,butthat one so Important that no work can be done without it; in fact no life work is done anywhere without it, for it is the medium through which all life is manifested, whether plant or animal. It holds the same relation to life that the eye does to sight, but it itself Ib not life any more than tbe eye Is sight. Itls called protoplasm, and In the cells of our seed it seems to have collected into little rounded mosses aud is lying perfectly quiet, In what ls termed its "resting state." When the seed begins to sprout, however, this protoplasm ls no longer at rest, but looks like the thin honey in tbe honey-comb and is in Incessant motion. Protoplasm then is the tool which is to make the whole plant structure, and along with it In the cells are to be seen the materials it must work npon, materials which have been stored there by the parent plant. By far the most Important one is Btarcb, so Important In fact that the others need not be mentioned here. Thus the microscope reveals the fact that the seed Is made op of cells, in each one of which there lies protoplasm the worker, and starch the material te be worked, both waiting for certalAondltlons in order that they may cause the young plantlet to burst Its shell and spring into life and beauty. It is estimated that ninety thousand millions of cubic feet of wnter pour over Niagara every Hour. Estimating the fall at 169feet, this means about 500 million horse-power running to waste. nlU/ltlrtt. fill T-u
