ANIMAL PRODUCTION. 27 Y 



readied that iu normal health, the acidity of the stomach is too high for the 

 production of hydrocyanic acid from linseed, but abnormal circumstances may 

 cause its production. 



" The above research explains the paradox that while a farmer considers 

 linseed one of the safest cattle foods and uses it for calf rearing, yet the 

 chemist shows that linseed in the laboratory readily gives off prussic acid, one 

 of the most deadly poisons. 



" Further, this research suggests a possible explanation of certain rare and 

 Xjuzzliug cases of cattle poisoning. Should a linseed, rich in cyanogenetic 

 glucosids, be fed to a beast suffering from indigestion of such a peculiar char- 

 acter that the food was not rendered acid, then prussic-acid poisoning might 

 set iu. Such a combination of circumstances must be very rare, but is by no 

 means impossible." 



The Pandacan forage factory, Z. K. Miller (PJiilipinne Agr. Rev. [English 

 Ed.\, 5 {1912), No. S, pp. ISS-lJ/l). — Brief reports are made on drying and 

 storing corn, testing grain rations, and artificially drying forage. 



Experiments made in crushing and drying grasses and green forage plants 

 showed that the cost was too high to be practicable. The experiments will be 

 repeated when a more economical dryer is obtained, as artificial drying of 

 forage is a necessity during the rainy season, or until irrigation systems can 

 be installed so that forage i)laiits can be grown in the dry season.

 breweries as a feed for live stock are discussed, and a contrivance for cooking 

 fresh yeast by means of a coiled steam pipe is described.

The origin and ancestry of Norwegian cattle, J. Frost {Milelnc. Zentbh,

 lar to those of Dettweiler (E. S. R., 26, p. 166), the first domesticated cattle 

 and horses in Norway were brought from Freisland or Jutland in Neolithic 

 times, are of the same ori^^n as the Finnish stock, and are black or black and 

 white in color. Red cattle were introduced at a later period and are of German 

 origin.

 pp. 216-279). — A description of the characteristics of the cattle in the region

 and managing.
