 The amount of plant food fin the manure, as has been previously stat ed, depends upon the kind of animal the age of the animal, the kind and amount of feed and the bedding 1 used. Horse manure is richer in nitrogen than either that of the COW or hog. An average sample of horse manure contains about 6 per cent nitrogen, per cent phosphoric acid and per cent potash. Cow and hog droppings contain more water and are poorer in plant food An average sample of either contains about per cent nitrogen. ? per cent phosphoric acid, per cent pot ash.
 Poultry manure is the richest of the farm manures because it con tains the semi-solid urine and there is little waste. An average sample of poultry manure contains about 12 per cent nitrogen, 9 per cent phos- phoric acid and per cent potash. It will thus be seen that it is es- pecially rich in nitrogen and phos- phoric acid,
 Estimating the manure of farm animals according to the plant food nitrogen, phosphoric acid and potash, they contain, they are valued about as follows: Sheep manure $4.20 per ton; mixed farm manure $2.25 per ton; hen manure $6.50 a ton; hog manure $3.20 ton; livery stable manure S2.45 a ton; COW manure $2.43 ton. This does not, of course, include the humus value, which may be several times the value of the plant food in the manure.
 There are at least two fairly ac- curate methods of calculating the amount of manure a definite num- Der of animals will produce during the year. Careful feeders have found that it may be fairly estimated that horse will yield 12,000 pounds of solids and 5000 pounds of liquids during the year; a COW will produce 10000 pounds of solids and 5000 pounds of liquids; sheep 76O pounds solids and 380 pounds liquids, a hog 1900 pounds solids and 1900 pounds liquids. With the average analysis given above the plant food may be estimated.
 Another method of calculating the manure an animal will produce is to multiply the amount of dry mat ter in the feed for one year by the following: For the horse multiply the amount of dry matter in his feed for one year by 2.1; for the COW. multiply the dry matter in the feed by Is. To the product of each case must be added the weight of the bedding. As an example suppose a COW consumes 20 pounds of dry mat ter day in her feed Multiply 20 by 3.S and we have 76 pounds of manure. To this we must add the bedding. If this be 10 pounds the manure will amount to S6 pounds.
 Heiden's rule for calculating the manure of farm animals is to esti- mate by a ton of feed For instance ton of green corn fodder is SUD- posed to produce 1,590 pounds of manure; ton of green alfalfa 2,166 pounds of manure; a ton of green cowpeas 1,260 pounds: a ton of corn silage 1,6O5 pounds of ma nure. Dry feeds: Corn fodder per ton produces 4.439 pounds manure; ton of alfalfa hay, 7,035 pounds manure; ton of cowpea hay 6,85S pounds manure; ton of millet hay 6,931 pounds manure
 Another way is to keep a record of the feeding. When one knows the amount and composition in fer tilizing constituents he can estimate the amount of nitrogen, phosphoric acid and potash in the manure. Cows in milk return only about 65 to 75 per cent of the manurial value Of their food in the excrement. Cows that are being fattened return from 80 to 90 per cent.
 How can the manure be saved with the least loss and the greatest profit? This is question of great importance, and suggestions will be made along this line. Let us hear from those who save, apply and get increased profits.
