with the facts as brought out in that bulletin. By placing the animals in a light, well ventilated stable, with sanitary surroundings, we were able gradually to get rid of the disease, and after 1911 did not have any more cases and have seen no signs of the trouble since.

There were received by us forty-nine goats, old and young, with two males, but owing to the conditions described we were not able to secure very many data in 1910. Only nine does were in condition to give milk that year. In 1911 conditions were much improved, as only two cases of Takosis developed, both in the spring. Early in 1912 all the animals were apparently normal, and of the twenty-eight old enough to breed twenty-three goats gave milk.

Cost of maintenance.— There were kept at the Station during the year beginning January 15, 1912, and ending January 14, 1913, twenty-eight adult females, three males, and nine kids that were dropped in 1911. It was not practicable with the number of goats that were kept together, and because of their uncontrollable, wasteful habit of eating, to keep a separate account of the amount of food consumed by individual animals. The whole amount for one day's feed was weighed and given the herd in two feeds, night and morning. As nearly as could be ascertained there was very little difference in the individual consumption of coarse food. About one pound of grain was fed daily to each animal. The food charged to the goats during one year was as follows:

(Adult males, 3; adult females, 28; kids, 9.)

Yield of milk.— For three years an accurate record was kept of the individual milk production of the animals we retained, together with certain animals that were bred after the goats were received. The record of total yearly yields follows:

TABLE II.- MILK YIELD OF MILCH GOATS.

It is to be noted that during 1911, the production of four of these animals, Nos. 6, 9, 10 and 11, was very satisfactory. With only one animal did this standard of production continue during 1912, namely, No. 11. This pure bred Saanen appears to have been a somewhat unusual animal, as her milk yield in 1911 was 1845.2 pounds. During 1911 and 1912 several of the animals gave from 700 to 900 pounds of milk, which is perhaps as good a yield as may be expected, excepting from animals considerably above the average. It should be noted that the period of lactation is considerably shorter than with cows, continuing from 250 to 300 days with most of the does.

The cost of food and milk. The average cost of food per goat for the year was $11.05, making the cost per day three cents. If it was possible to get any number of goats together like No. 11, the Saanen, the keeping of goats would be a profitable proposition for a family supply. On the basis of a food cost of eleven dollars a year, her milk, during the year of best production, would cost 1.27 cents a quart, the average for the three years being 1.65 cents a quart. The best Toggenberg one year produced milk for 1.62 cents a quart, but her average for the three years was 2.70 cents a quart. The average food cost of the milk, for 1912, of all the goats was 4 cents a quart, and the average cost for the three years was 3.4 cents a quart. The average fat content of the milk was 3.71 per ct., of total solids 11.76 per ct. The average food cost of a quart of milk with the Station herd of 25 Jerseys during the past three years has been .92 cent per quart; the average fat content 5.9 per ct., and total solids 15.20 per ct. This shows the cows to be cheaper producers of milk and milk solids than the goats under the conditions prevailing at this Station.

Composition of the mixed milk.-During May and June of the year 1912 the mixed milk of the herd was analyzed daily. This was done by the use of the lactometer and the Babcock test. Comparison of this method with the gravimetric method showed it to have the necessary accuracy. The results follow:

Examination of these figures shows that the percentage of fat in the mixed milk varied from 3.2 per ct. to 4.4 per ct. As a rule, the fat percentage ranged between 3.5 per ct. and 3.8 per ct. The solids-not-fat ranged from 7.72 per ct. to 8.61 per ct., the general range being between 7.8 per ct. and 8.2 per ct. The total solids ranged in general between 11.4 per ct. and 11.9 per ct. Analyses of the milk from individual animals showed much greater variation. This is illustrated by the figures which follow:
