Tests made at creameries (pp. 4(50, 401). — A table sbovrstlic ponutlsof 

 milk and of butter fat (as found by test) brought by each of seventy- 

 eight patrons to two creameries in one day. At creamery A the butter 

 fat in the milk supplied by forty-eight patrons ranged from 3.3 to 5.2 

 per cent; or to make 1 i)ouiid of butter fat, 30.3 pounds of the poorest 

 or 19.2 pounds of the richest milk would be required iMilk brought 

 by the thirty patrons to creamery 1> contained from 3.7 to G.4 per cent 

 of fat, requiring from 15.0 to 27 i)Ounds of milk for 1 pound of butter fat. 

 A description is given of the method em[)loyed at a creamery in De Kalb, 

 Illinois, of paying creamery patrons on the basis of the amount of butter 

 fat in the milk. A rei)ort of one creamery for Octoli)er, 1890, "shows 

 that the p.itrons who were paid on the test plan received from 93 cents 

 to $1.32 per 100 pounds of milk." 



SumpUng of milk to be tested (p. 401, illustrated). — An illustrated 

 description of the method of sampling cm[»loyed at a creamery at De 

 Kalb, Illinois. 



Comparison of different milk tests with each other and icith the gravimet- 

 ric laboratory analijsis (pp. 462-4C()). — Notes are given on the Babcock, 

 l*atrick brine bath, and the Beimling (Vermont Station) nu'thods of 

 testing milk, and comparisons of the results by these methods and the 

 gravimetric (Adams, sand, and asbestos) methods for twelve samples of 

 whole milk, five of skim-milk, and three of buttermilk. Yaiiations in 

 the lesults by the three graviuietric methods, amounting iii some cases 

 to 0.28 per cent of fat, make the results of the comparative test of these 

 and the simple methods unsatisfactory. The showing for the latter 

 was, m general, quite good. 



Device for measuring acid into the test bottles (pp.460, 407, illustrated). — 

 An illustrated description of an ap[)aratus for conveniently measuring 

 the acid to be used in the test bottles in the Babcock method for testing 

 milk. 



Chemical analyses of "germ meal" akd "oatdust feed," 

 E. II. FarkincxTon, M. S. (pp. 407,408).— Analyses of these two feeding 

 stufifs are compared with the average composition of oats, wheat bran, 

 corn meal, acd timothy hay. The germ meal, which resembled oats in 

 composition, sold in car-load lots at $10 per ton.

Winter protection of the peach tree, E. A. Topenoe, M. A., 

 AND S. C. Mason, B. S. (pp. 81-84).— In view of the difficulty of secur- 

 ing a crop of peaches in Middle and Northern Kansas, owing to the 

 severe cold of winter and the late frosts of spring, the station has mado 

 experiments in protecting the trees. In the fall of 1887, after pruning 

 the branches were drawn in toward the main stem and the tree was 

 covered with boughs of evergreen, but this plan did not give satisfac- 

 tory results. In 188S the trees were bent down as close to the eartl\
