THE DAIRY. 199 



Again, selecting six cows each year from the number kept during the whole year, and 

 such represent the best milkers, we have 



In first year, twenty-five native cows, the six best, gave .... 2,919 quarts. 



In second year, twenty-five native cows, the six best, gave .... 3,047 quarts. 



In third year, sixteen native cows, the six best, gave ..... 2,562 quarts. 

 Average of twenty-two cows to select from; the six best in the average of three years, 

 2,842 quarts. 



In fourth year, thirteen Ayrshire cows, the six best, gave .... 2,169 quarts. 



In the fifth year, fourteen Ayrshire cows, the six best, gave . . . . 2,747 quarts. 



In the sixth year, thirteen Ayrshire cows, the six best, gave .... 3,186 quarts. 



Average thirteen and three-tenths cows to select from; the six best in the average of 

 three years, 3,034 quarts. 



As a matter of fact in obtaining these results we selected from thirty-five different 

 native cows and seventeen different Ayrshire cows. 



It will also be instructive to compare the records of the same natives kept during three 

 years with the Ayrshires under similar circumstances. 



Of the eight native cows retained through the three years, from a high opinion of their 

 worth, I present the following figures: 



First year, 

 Second year, 

 Third year, . 



Average Ibs., . . 5,800 4,755 3,918 4,425 4,892 4,644 4,966 4,439 



Average qts., . . 2,673 2,191 1,805 2,039 2,254 2,140 2,288 2,04? 



Of an average of 2,179 quarts yearly. 



Or the ten Ayrshires retained through three years, we have 



No. 1. No. 2. No. 3. No. 4. No. 5. No. 6. No. 7. No. 8. No. 9. No. 10. 



Fourth year, . 5,912 6,264 7,176 3,086 6,348 6,305 6,578 6,220 8,596 5,740

Sixth year, . 7,293 5,656 5,636 4,213 5,571 6,299 5,675 6,525 4,846 5,532 



Average Ibs., . 6,214 5,656 6,222 3,646 6,030 5,917 5,994 5,964 6,859 5,446 

 Average qts., . 2,823 2,606 2,867 1,680 2,779 2,726 2,762 2,748 3,160 2,508 



Or an average of 2,666 quarts. 



These figures show conclusively that the best cow in the barn one year is not necessarily 

 so the next, and that a farmer can give his average yield for one year, and not necessarily 

 give the milking average, or average profit of the dairy on his farm.&quot; 



From the above it will be seen that with the same expense in feeding, there is a credit 

 to the Ayrshire of 500 quarts per head, as a common difference between the amount of milk 

 rendered by the pure-bred Ayrshire per year, and the best native cows respectively. With a 

 herd of twenty cows, such a difference as ten thousand quarts of good milk from having an 

 improved breed is quite an item. By comparing the average yield of the best native cows, 

 as above given, with that of other pure-bred dairy stock, as given in connection with the 

 description, etc., of the pure-bred dairy breeds, the difference will be found equally striking. 



The foregoing facts and figures, coming from such unquestionable sources, should be 

 conclusive evidence as to the benefits resulting from the use of improved breeds in the 

 dairy. If our dairy farmers would use only thoroughbred bulls of the Jersey, Holstein, 

 Ayrshire, or some other approved milk breed selecting a bull for such use that has a good 

 &quot;escutcheon,&quot; with other attending milk points, they by such use, would soon possess 

 improved herds of grade cows, and by continued use of such thoroughbred bulls, for a few 

 years at a trifling cost, would be the owners of herds nearly as valuable as the pure-breeds.
