Test of d.aiky apparatus, G. H. Whitciikp,. B. S. (pp. 3-16).— 

 This contains an account of tests made at the Station during a 

 farmers' institute, hekl January 8, 9, and 10, 1889, and conducted by 

 a committee of three persons agreed upon bj'' officers of the Granite 

 State Dairymen's Association. State Board of Agriculture, and the 

 Exj^eriment Station. The apparatus, milk, and chemical and other 

 work "were furnished b}- the Station. 



(1) (Jompuratice test of foe di/ffeient systems of setting milk for 

 cream raising. — The efficiency of each system was measured by the 

 percentage of the fat in the milk which was recovered in the butter. 

 A test was made Avith 150 pounds of milk set by each system, 75 

 jjounds in tlie morning and 75 at night. Chemical analyses were 

 made from samples of milk before setting, skim-milk, buttennilk, 

 and butter for each system. The relative merits of the butter made 

 by the diiferent systems were also tested by a committee of experts. 

 The bulletin contains a full account of the tests and of the systems 

 tried and comparative statements of the results obtained. 



(2) Test of three chvrns. — The details are reported in tal)ular form, 

 and the results as given show " that there is practically no difference 

 in the efficiency of these three churns," though they differ somewhat 

 as regards ease of handling and cleaning. 



(3) Butter exhihit. — Samples of butter from fourteen creameries 

 and eleven private dairies were exhibited. An expert taster selected 

 from each class the samples which were first, second, and third best. 

 A description is given of the methods used in making the butters 

 which received the awards, and the results of chemical analyses of 

 fifteen samples of creamery butter and five of dairy butter are also 

 stated, including the per cent of fat, water, casein, and salt, and the 

 volatile fat acids. A comparison of the results of these analyses 

 with the opinions of the expert taster indicates that something more 

 than chemical analysis is required to determine the marketable quali- 

 ties of butter.
