128 HOLSTEIN-FRIESIAN CATTLE. 



on the crime of making fraudulent records, it does not follow that no such 

 records have ever slipped into this registry. But it courts investigation, assured 

 that the closer the records of our breed are examined the more reliable will they 

 appear, and the firmer the ground of this system of registry. 



The following instructions for making officially authenticated butter 

 records for Advanced Registry are issued by the superintendent of Advanced 

 Registry of the Holstein-Friesian Association of America, Mr. S. Hoxie, of 

 Yorkville, N. Y.: 



1. Such records, to compete for the prizes of the Holstein-Friesian Associ- 

 ation of America, may be made by the churn, or by the Babcock test, or by 

 any other method approved by the Association of Official Agricultural Chemists. 



2. All such records must be for seven consecutive days, and must be super- 

 vised by the officer of some experiment station or state institution, or by the 

 superintendent of Advanced Registry or some inspector designated by him. 



3. The person supervising must see the cow milked dry at the beginning 

 of the test and be present at each milking thereafter and weigh the milk, and 

 have such complete control of it in every process of the test as to insure positive 

 accuracy in the results obtained. In his report of the test the supervisor must 

 give full details to the satisfaction of the superintendent of Advanced Registry 

 and make an affidavit to the accuracy and truthfulness of the same. 



4. In all cases where possible the supervision should be by an officer or 

 appointee of an experiment station. To obtain such supervision owners of cows 

 contemplating such tests should early begin correspondence with the directors of 

 such stations and also with the superintendent of Advanced Registry. Direc- 

 tors of such stations are always disposed to do such work for their constituency 

 but they sometimes have to employ special assistants for it. In preliminary 

 correspondence with them it is not necessary to give the names of cows or the 

 date of contemplated tests. Its object is simply to induce necessary prepar- 

 ations. 



5. It is always wise for owners to know just what their cows are doing. 

 A Babcock testing machine is almost indispensable to this. The method of 

 using it is easily learned. It takes but little time, it takes but little milk, and 

 it is accurate. In addition to the ordinary instructions accompanying the 

 machine the following are suggested. In adding the acid the bottle should be 

 held at an angle so as to cause it to flow slowly down the inside of the wall 

 the farther the neck of the bottle is from a perpendicular position the better. 

 When about half of the acid is added shake the bottle in the ordinary way until 

 the acid is mixed with the milk, then add the remainder and mix again. After 

 revolving the bottles the usual time fill them with hot water only to the necks, 

 then revolve a minute or more, then complete the filling to raise the fat into the 

 graduated necks and revolve again. Always use hot water and keep the bottles 

 in hot water until the per cent of fat is accurately read. The bottles should be 

 cleansed in hot water after each test. 



6. To make an official record eligible to receive a prize it must be entered 

 in Advanced Registry. Application for such entry is made separately from the 

 report of the supervisor. There are no fees for entry. 



7. The value of official records can hardly be overestimated. The cost in 

 comparison is trivial. It includes traveling expenses of the supervisor and pay 

 for his time when required. Such charges are moderate. 



8. All blank forms are free. There is not a breeder who has made official 

 records but will gladly give information on the subject, and the superintendent 

 of Advanced Registry invites correspondence.
