Sampling and testing The proper sampling of milk for 

 testing is very difficult. Every care was taken that all the 

 first drawn milk and all the strippings were included in the 

 bulk from which the sample was taken, as the former is 

 poor, and the latter rich, in butter fat. Each lot of milk 

 was thoroughly mixed before the sample was taken, and 

 this was taken from the middle of the bulk, this precaution 

 being necessary, as cream soon begins to rise to the surface. 

 The samples have nearly all been taken by Dr. Potts, Mr. 

 R. R. Swann, B.Sc., Mr. Geo. Willis, and Mr. James 

 McLaren, jun. 



All the samples of milk from Oiferton and Broomhaugh 

 have been tested by Mr. S. H. Collins, the College Lecturer 

 in Agricultural Chemistry. Those at Cockle Park were tested 

 by Mr. J. H. J. Farquhar, B.Sc. ; at Seaton Delaval by Mr. 

 R. R. Swann, B.Sc. ; and at Alnwick by Mr. A. W. Patten. 

 In all cases the fat was ascertained by the Gerber butyro- 

 meter; and from this and the specific gravity the solids not 

 fat were calculated. Mr. Collins checked his results by 

 other methods. 



Mr. W. T. Lawrence, the manager of the Cumberland and 

 Westmorland Farm School, has placed the results of a year's 

 tests of the school herd at the disposal of the College. 



OFFERTON RESULTS. 



At Offerton, the milk of each of twelve cows was tested once 

 a fortnight, from January 10th till March 21st, 1903. The 

 cows had all calved between July 19th and December 20th,. 

 1902. They were milked three times a day, at 5 a.m., 1 p.m.,. 

 and 6 p.m., the intervals being therefore 11, 8, and 5 hours. 

 The amount of milk given by each cow averaged about 11J 

 pints in the morning, 7 pints at mid-day, and 4 pints in the 

 evening, this being equivalent to about 2J gallons per cow 

 daily. The milk is all retailed in the Sunderland district. 

 Each cow received daily 100 Ib roots, 8 Ib hay, 10 Ib cake and
