(COnUnued from Page p fat by simple multiplication All this if done every day would take considerable time, but there is a simple way to arrive at a fairly accurate esti-
 mate of the amount of butter fat pro-
 duced in a year. This is the method
 that is being followed by many prac- tical dairymen in different parts of the
 country, and it has been found by ac- tual experiment where the milk has
 been weighed every day and also
 tested that it is very nearly as ac-
 curate. The plan is this. to weigh the milk on four successive days, and take
 samples as outlined above, the amount of milk for the four days multiplied by the test of the composite sample, will give the amount of butter fat for the four days, this multiplied by 71a will give the amount for thirty day month.
 In this way we would find that Brindle has given 129 pounds of milk
 in four days. Her test we find is 3S as we commonly write it, but for the purpose of multiplication we must keep
 our decimals, and so we write 1t 03S,
 then we find the result is 4.9 pounds of butter for the four days, and null tiplied by 71a we have 3675 or the amount for the month
 A method of this kind does not in volve so much labor, and costs bur
 teSio III IlOuey, anu the GnQ or the year we have some figures that are worth a whole lot. We find that old Brindle that we have thought was a pretty good cow has only produced 275 pounds of butter fat, while Nigger has with a test averaging Az, made $40 pounds While Bess that we have never thought much of has beaten them both by giving 6410 pounds of milk for the year testing on an aver age 52 and producing 34332 pounds of butter fat We look over the record for the year and we see that she has won by being persistent milker. and by giving an extra good quality of milk
 While Broncho is way down with only 150 pounds of butter fat to her credit
 Now then we use some more 4rith- metlc, and we figure the cost of keep ing a COW something like this: 10 per cent interest on land worth 15O per acre, S15; water, s2.5O; cost of irri- gating, fixing fences, etc., S1.O0; & total of $1S.50. Now it will take about two acres to feed a COW depending on pas turage alone or nearly so. Of course there are many who claim to keep them on less. but we have failed to find any one that is actually doing SO. and we think that it is a conservative estimate to figure the cost of keeping COW to be s37 per year. It will cost dpout Sz.uV per month to milk and care Tor her so that a COW that produces 175 pounds in the season will earn at soc per pound, s52.50 and her cost, fig uring months care at s2.0O will be s51, which will leave a balance of s15O. If you are renting her and paying SlO0 per month for her you are $1O5O to the bad.
 On the other hand the COW that has produced 343 pounds has earned S10290: her feed cost is the same as the other. She has cost more for labor because she mixed Il months instead Of seven so her labor cost was s22 making total of s59, deducting this we have a profit of s43.90, and then we pay the $1.00 per month rent and have left $31.90, as against a loss of sIO.5O
 And stfU there are some who say they cannot afford to go to the trouble and spend the time to learn what their herds are producing as individuals.
