value was 66 cents per ton lower and its selling price was 66 cents higher.

In order that our readers may be able to compare the analysis and value, as well as the selling prices, of fertilizers of the years 1879-80, 1891-2 and 1892-3, we make use of the following table, in which the average analysis of each year is used in connection with the valuations of 1892-3 as the basis of the calculation:

A comparison of the records of the three years given in the tables, leads to the following conclusions:

Complete Fertilizers.--From 1879-80 to 1892-3 there has been a decrease in the average available phosphoric acid, from 9.32 to 8.46; during the same time the insoluble phosphoric acid has been slightly decreased; owing to the introduction of special potassic fertilizers for potatoes the potash has been slightly increased; the nitrogen has been decreased; the valuation (both being calculated from the values of 1892-3) has undergone very little change, while the average selling price has been decreased to the amount of $5.56 per ton; or that, in other words, our farmers are now buying the complete fertilizers which they now use for $675,000 less than they would have paid for them in 1879-80.

Acidulated S. C. Rock.-Since 1879-80 there has been an increase of available phosphoric acid from 11.64 to 13.59, and a decrease of the insoluble from 6.08 to 1.89, or a total decrease of 4.19 per cent. The value has increased but 48 cents per ton, but the selling price has fallen $8.34 per ton.

Ground Bone.-In this class of fertilizers there appears to have been a slight increase of phosphoric acid and a falling off in the percentage of nitrogen. During the same time the selling price has decreased $2.02 per ton.

The Production of Manure.

In a recent experiment by Prof. Watson at Cornell Experiment Station, important items in connection with the production of manure were ascertained. Among these may be instanced the connection between the amount and character of the food and the amount and value of the resulting manure, the relative amounts of nitrogen, phosphoric acid and potash in the manure, and the relation of the amount of water consumed to the amount and character of the manure.

Tests were made with sheep, pigs, calves and horses; they were kept so that absolutely everything consumed was retained or given off in the form of excrement and urine, and its exact weight ascertained with certainty.

In the experiment with horses, the minutia of which we omit for want of space, the following table shows the results of the formation of the inanure:

Total weight of horses,

Plaster used,

Straw bedding used,

Total weight of manure,

Value of excrement per year per 1,000 pounds live weight,... $27 74

Value of manure per ton,

Value of excrement per ton,

The analysis of the manure gave the following results: Water, 48.69; nitrogen, 0.49; phosphoric acid, 0.28; potash, 0.48 per cent.

Four work horses and one two-year-old colt were put in for this experiment to test the results of 24 hours' feeding and manure forma

tion; as a result it was found, as the average of a number of trials, that the manure had a value of .076 cents per day, or a total annual value of $27.74, and that the excrement received (average) amounted to 48.8 pounds for each 1,000 of live weight.

The experiment with pigs appears to have been more complete and to have determined a larger number of doubtful points. The following tables give, in a condensed form, the result of this experiment:

No. of experiment.

An examination of the table, with the light given by the character of the food used by each lot during each day, shows that the high value of the excrement (daily) of the first two lots was due to the rich (in nitrogen) character of the food consumed. From the first table the reader will note that lots 1 and 2 consumed a considerable amount of meat scrap which cost $35.00 per ton, and which contained about ten per cent. of nitrogen.

In reviewing this experiment Prof. Watson thus alludes to the results: "It will be noticed that the value of the excrement per ton is nearly the same in each of these three experiments, while the value recovered per day is nearly twice as much when the ration consisted of corn meal and meat scrap as when corn meal, wheat bran and linseed meal were fed. The highly nitrogenous ration greatly increased the liquid voidings and this, more than any other one thing, caused the great weight of total voidings per day without proportionately increasing the percentage of nitrogen."

The result of a similar experiment with cows is shown by the fol lowing table:

During the test the cows were fed as they usually were during the winter, and no change, except that needed to keep a record of the voidings, was made in the regular habits of the herd; it is therefore claimed that this table very fairly represents the results in manure of the Station herd during the whole winter.

The result of careful analyses proves that the manure from the dif ferent herds had the following values per ton: No. 1, $1.76; No. 2, $1.97; No. 3, $1.88, and No. 4, $2.47, or an average value per ton of $2.02.

The report gives no explanation for the great increase in the value of the manure from herd No. 4, as compared with the others, but this explanation can no doubt be obtained by a study of the variations in feed as shown by the preceding table; the result, in its minutia, is shown by the following table:

RECOVERED FROM ONE THOUSAND POUNDS OF LIVE WEIGHT OF ANIMAL, PER DAY.

A similar experiment made with sheep confined upon water tight galvanized iron pans, exhibits the results as set forth in the following table, and these results will be found well worthy of the careful study of all sheep feeders, as they furnish data found in no other experiment and in such a condensed form as to be specially valuable:

A careful average of all the experiments of the series, of which we have noted but a few, is shown by the following tables, from which the value per ton of each kind of manure will be noted, but the reader must make due allowance for the fact that this valuation is placed upon the 'manure as soon as it is formed, and not after it has laid under a shed or out in the weather for five or six months, and
