Reindeer moss as a feed for milch cows, H. Isaachsen (Bcr. Xo/v/r.s Landhr. 

 HdiskoJc.s r//7.-.s.. l!)().'>-6. ftp. 202-216). — An experiment conducted hy the author 

 Avith 8 cows for a period of over 4 months showed tliat 1 Iv?. of moss can replace 

 3 kg. of turnips in rations for cows without producing any deleterious effect 

 on the milk yield, the weight of the cows, or the fat content of the milk. The 

 average of 5 analyses of reindeer moss was as follows : Water, 48.3 per cent ; 

 fat, 0.96 per cent; protein. 1.17 per cent; nitrogen-free extract. 18.1 per cent; 

 fiber, 20.8 per cent; starch value per 100 kg. (Kellner). 18 kg.; digestible 

 protein (artificial digestion), (i5 per cent. — f. w. woll. 



Department of dairying, W. D. Saunders (Virginia tSta. Rpt. ltHi6, pp. 

 Jil--'{9). — Brief notes are given on the work of this department of the station 

 during the year and ofttcial 7-day tests of 4 Holstein-Friesian cows are reported. 



Investigations on the influence upon milk production of the nonproteid 

 nitrogenous compounds of feeding stuffs, A. Mokoex, C. Heger, and F. 

 Westhausser (TAUiflir. VerH. mat., 65 (1901). No. :>-6. pp. J, 1 3- W)).— Thin 

 experiment is in continuation of the series of investigations previously noted 

 (E. S. K., 18. p. 171 I. 



During the first and fourtli ]>eriods of 11 days each a goat and a sheep were 

 fed a normal proteid ration. During the second period the i)roteids were in 

 part replaced by amids prepared by extracting young ])lants with boiling water 

 and evaporating the fluid extract to the consistency of n sirup. During the 

 third period the amids were replaced by carbohydrates. The most favorable 

 influence upon milk production was exerted by the proteid ration. The amids 

 were not eijual in value to the proteids, but were much superior to the carbo- 

 hydrates. Further experiments along this line are i)];inned. 



On the influence of the feed on the creaming quality of the milk, .7. 

 Salanb (Bcr. Xorf/cx La)i(Un: Huii<kolc>^ Virks.. niD.l-d. pp. 220-226). ^The 

 experiments conducted by the author indicate that milk produced on rations made 

 up mainly of hay and straw, with only small amounts of concentrated feeds, 

 gives considerable more cream than that produced by cows fed richer rations, con- 

 sisting of roots and only a little bay and straw, with a good deal of concentrated 

 feeds. This appears to be due to other properties in tlie milk than its fat con- 

 tent, such as a change in viscosity, differences in the condition of the casein, 

 etc., which may be traced to the character of the feed eaten by the cows. —

An investigation into the quality of milk produced by different breeds of 

 cows at Elsenburg Agricultural College, (i. X. Blackshaw (Af/r. '/our. Cape 

 (Jood Hope. SO (1901). Xo. 3. pp. 3'>'i-3'tS) . — Determinations were made of the 

 fat content of the milk of the Friesland, Jersey, Shorthorn, and Ayrshire breeds, 

 and also of native Cape of Good Hope cows from October, 1 !>()(">. to February, 

 1907. The milkings were made at 6.30 a. m. and 4.30 p. m. The nulk of the 

 Friesland. Shorthorn, and Ciipe cows averaged less than 3 jier cent of fat in 

 the morning. The milk of individual cows very frequently fell below the stand- 

 ard of 3 per cent of fat. The author, therefore, believes that much evidence 

 should be secured before the British standard of 3 per cent of fat and 8.5 per 

 cent of solids-not-fat sliould be accepted in Caiie Colony. 



The properties and value of the milk of sheep, A. Burr (Molk. Zf(/.. 21 

 (1901), A'o. Ui, pp. 359-361). — This discussion of the composition and value of 

 sheep's milk includes a compilation of analytical data. 



On the milk production of Karakul sheep, L. Adametz ((htcrr. Molk. Ztti.. 

 IJ, (1901), Ao.s'. 6, Pit. 13-15: 1. pp. SIS!), flt/s. 5). — This Asiatic breed of sheep, 

 known also as Persian siu>ei), is descriiied and its importance for middle Europe
