Since that date, reports of experiments carried on at the Station have from time to time been published. Those reports, being out of print, are not now accessible to the public. The frequent requests that come to the University have led to the belief that a real service would be rendered to the cause of practical agricult- ure by a republication of some of the papers that seemed to be of most general and practical importance. By reason of this belief, the following papers are now offered to the larger agricultural public. C. K. ADAMS. Cornell University, Dec. 10, 1886. CO NOTE Nels PAGE. I.

EXPERIMENTS ON THE COST AND VALUE OF STABLE MANURE, By Prof. I. P. ROBERTS. (Analyses by Mr. F. E. Furry and Mr. A. M. Breed.) I. The Value of Well-preserved Home-made Manure. Wuen the University farm was taken in charge by the present Professor of Agriculture it was found to have been much exhausted by continuous cropping, with insufficient manuring. Commercial fertilizers were applied, with poor success in producing remunerative crops. Hauling manure from the village in the valley, four hundred feet below the site of the farm, proved to be little more satisfactory, on taking into account both its cost when delivered on the farm, and its poor quality. On turning attention to the supply made at home it was found to have been poorly cared for, and badly wasted on leaky floors, in large uncovered yards, or in overheated and fire-fanged piles. To prevent such waste, which subsequent experience proved to be much greater than was at first imagined, a large covered yard was built, and with such satisfactory results that we have long since ceased to buy manures of any kind; we find that we =a can produce large quantities on the farm, worth three or four times as much per ton as that which was formerly bought in the village. Vor two successive seasons an attempt has been made to determine the value of this stock of home-made manure, in the same manner and on the same basis as that by which the valuation of a sample of a commercial fertilizer is estimated. The accumulated layer of mixed manure of cattle and horses was at the end of the first season about two feet thick, and packed quite solid by the tramping of the cattle over it. A large number of samples of about ten pounds each were taken at the depth of about a foot, chopped up and most carefully mixed together, and a sample of this mixture was analyzed, with the following results : IMOISRURG i222 tae oe enc at ete en Yast ner etenacgeeae wesc 72.95 per cent.

Numerous experiments in Germany appear to show that cows in milk take from their food about 20 per cent. of its manurial value. Deducting this 37 cents from the above, we have $1.51 as the value of the manure of three cows for three days, or 16% cents per cow per day. It will be noticed that the cows selected for this experi- ment were above the average in weight, and that they were liberally fed. As to the question of profit, we have the following ex- hibit, the milk being reckoned at 24} cents pen pound; that being its value to the University, in the barn, after it was drawn from the cow.

Experiments with Grass. 1 Grass—Different Fertilizers. 1876.—The crop consisted of clover and timothy in about equal proportions, and was cut June 24. The soil was gravelly, inclining to a sandy loam. The plots were one square rod each, divided accu- rately by 2X4 scantling. The plaster used was from Cayu- ga beds unless otherwise designated. The results should be studied with regard to the yield of grass rather than hay, as the latter cannot be uniformly cured.

I, Clover—Different Manures. 1877.—These plots contained an exact square rod, and were divided by laying down 2x 4 scantling, which were fastened together by strips of board nailed on top. The grass was mowed very close after the removal of the scantling, and immediately weighed ; for shrinkage in curing, see No. I, D. At the time of locating the plots they all appeared perfectly uniform. The second growth of clover on the plots treated with ground bone was relished very highly by the cattle, these plots being eaten close to the ground, while the clover on the others was still of a considerable height. —— a = 99 1 12 13 214 lbs.

Grass—Different Fertilizers. 1876-7.—One plot 4 rods by 5 was flanked on either side by a plot 4 by 24 rods. The plots were divided by shallow trenches carefully cut to line. The grass consisted of timothy and clover about equally mixed. The large plot, numbered 3, received a dressing of 50 lbs. of the Stockbridge Fertilizer for grass; the other plots, numbered 1 and 2, were unmanured. One of these plots yielded 640 Ibs. of grass, or 260 Ibs. of hay ; the other, 697 lbs. of grass, or 274 Ibs. of hay. The totals and the yield of plot 3 are given in the following table, in pounds: Grass Hay Grass.| Hay. per acre. | per acre. | |Nos.1and2.| 1331 | 534] 10,712 4,272 Wo Bic asscook 1697 | 618 9 The experiment was repeated in 1877, when the unfertil- ized plot, of the same size as one of the unfertilized plots of the previous year, yielded 765 Ibs. of grass, and the plot with Stockbridge manure, half as large as the manured plot of last year, 1,008 lbs. For shrinkage, when converted into hay, see the statement of result of the previous experiment ; the grass this year consisted of timothy mixed with a little clover. The same per cent. of shrinkage should not be ap- plied to clover (II), as it would be far too small. E. Experiments with Mangel - Wurzels, 1879.—The summer was:dry and unfavorable, and the crops of all the plots were damaged by grasshoppers, that ate off the top in July.

EXPERIMENTS IN CATTLE-FEEDING. By Pror. I. P. ROBERTS. EnsILaGE For Youne CarrLe and Breer Cows.— Three two-year-old, half-blood Holstein heifers were se- lected, which had previously been fed on hay exclusively. First period —The ration consisted of ensilage, 50 Ibs., and malt sprouts, 0.5 lbs., per day and animal. For the composition of these fodders see report of De- partment of Agricultural Chemistry. All weights were taken at 8 o’clock A. M., after feeding but before watering. 1 When weighed. | No. 14. | No. 16. | No. 17.| Total. Ibs. Ibs. lbs. lbs.

The apparent gain of 216 pounds during the first week was largely due, without doubt, to an increase in the contents of the stomach. If the weight of March 3 is taken, the total gain in the SS ie following three weeks is but 14 Ibs., or 0.22 lb. per day and animal. It is evident that this was about as near a mainte- nance ration as it is possible to get, for while one animal gained 32 lbs., the others lost 8 and 10 lbs. respectively. Second period.—On March 25 2 Ibs. of cotton-seed meal was added to the daily ration of each animal. On April 14 their total weight was 2,672 lbs., a gain in the three weeks of 142 lbs., or 2.25 lbs. per day and animal. This experiment indicates that Southern-corn ensilage forms a maintenance ration when fed in suitable quantities, and that it is economy to feed it in conjunction with some more concentrated food. During the first as well as the second period the animals appeared to be making rapid growth, yet the scales showed that the weight of two of them decreased. For several months after being turned out to pasture the ensilage-fed animals appeared far thriftier than others of like age and size which had been wintered on hay. Beef Cows.—The cows had been “dry off” about three weeks previous to the first weighing ; two were natives and one (No, 10) was a half-blood Holstein ; all had been milked for about ten months and were thin in flesh. They were offered for sale at three cents per pound, or $99.00, but owing to the high price of feed no purchaser was found. From February 21 to April 5 their ration consisted of ensilage 52 Ibs., and corn meal 12.5 lbs.; from April 5 till sold, ensilage 50 lbs., corn meal 9.4 lbs., and cotton-seed meal 2.8 lbs.; or in volume-measure in the last case, six quarts of corn meal and two quarts of cotton-seed meal.

Blige Gain in Weight by Steers an a Moderate Fattening Ra- tion, and on Grass.— Three steers, purchased March 4, were weighed daily at first, beginning March 13, after they had become ac- customed to their new surroundings, and afterwards every other day for two months, while fed on the following ration: March 13 to 16, ensilage 30 Ibs., cut corn-stalks 4 lbs., malt sprouts 5 lbs., and corn meal 3 lbs. March 16 to 23, the same, except that 2.5 lbs. of bran were substituted for 2.5 Ibs. of malt sprouts. From March 28 on, 1 lb. of cotton-seed meal was added to the ration. From March 27, 1 1b. of corn meal was replaced by 1 lb. of cotton-seed meal. All weights ‘were taken after eating and before drinking. The weights are given in detail to show the frequent wide varia- tions from day to day. March.; Ibs. | lbs. lbs. April. Ibs. lbs.

The marked dif- ference between this plot and plots 3 and 5, two weeks after the grain was sowed, led to a careful determination in the laboratory of the amount of moisture present in the first eight inches of soil. Plot 3 contained 11 per cent. water, and plot 4 11.6 per cent. This difference shows that there was present in the soil 12,903 lbs. more of water per acre in the first eight inches of plot 4 than of plot 3. Wheat, broadcast and drilled seeding compared.

There is a very noticeable variation from year to year in the per cent. of seed that germinates, and in the amount de- stroyed by insects and other enemies before the winter sets in. The thin seeding frequently does well until freezing and thawing occurs during the last of winter, when it is injured far more than thick seeding. If every condition has been favorable up to spring it some- times happens that dry, windy weather prevails, and the thin seeding does not tiller as it should, or tillers so late that a large proportion of the heads are low in the standing grain, small, and poorly filled, while the heads of the thick seeding will be more uniform in size and have less small and’ shrunken grain. One bushel of seed per acre would be ample if all the conditions were at the best; but they seldom are. Therefore it appears wiser to be liberal with the seed than to take so many risks. Wheat, varieties, Kxperiments of 1880-1 : Farm-yard manure was applied to the surface and har- rowed in at the rate of six cords (twelve loads) per acre, and 200 lbs. of phosphate per acre was drilled in with the seed. — 101 — No injury to the germination of the seed appeared, as the ground was quite moist at the time of sowing.!
