EXPERIMENT STATION RECORD. 



"It will ]>v seen tliat the orrois were lewH than one-half per cent, a degree of accu- 

 racy which comparew favorably with the most exact laboratory methods. The 

 results for the water produced were not so satisfactory, but the source of this error 

 has been apparently discovered and it is anticijiated that later tests will give more 

 satisfactory results." 



Sheep, J. H. Grisdale and R. Robertson {Ca}iada Expt. Fmins Rpt>i. 190J, jiji.SO, 

 261). — Brief notes regarding the sheep kept at the Central and Maritime Prfiviiices 

 Experimental Farms. 



Sheep, W. II. Dai.kvmple {Louhktnn Stas. Hiil. 74, ■.^, ^cr., ])p. 197-216, Jix/s. 11). — 

 The importance of improved breeds is urged, the principal breeds of sheep are 

 described, and shee]) raising is discussed with special reference to local conditions, 

 the experience of the station in raising sheep and the cultivation of different crojis 

 suited to their needs l)eing lirietly cited. 



Digestion experiments with sheep, J. V>. Lixosey et al. {Mai^ndchnsctts Sla. 

 Bpt. 1902, pp. 82-101). — This gives in tabular form the results of 185 trials with 73 

 feeding stuffs made at the station during the period from 1894 to 1902. The coeffi- 

 cients of digestibility have been published from time to time in the reports of the 

 station. The influence of drying and curing on digestibility was studied with wheat, 

 sand vetch, and barnyard millet. The curing process ap[)arently did not affect the 

 digestibility of the wheat and vetch, while it noticeably decreased that of barnyard 

 millet. 



The pentosans, J. B. Lindsey {MasmchuKcits Sta. Itpt. 1902, p}i. 69-81).— The 

 author reviews the literature relating to the determination and digestil)ility of pen- 

 tosans, and reports in tabular form the experiments on this subject which have been 

 made with sheep at the station, the principal data obtained being summarized in the 

 following table:

The conclusion is drawn "that the pentosans are as digestilile as any of the other 

 fodder groups (except in the presence of excessive incrusting substance), and that 

 the digested material is practically utilized in the animal organism to the same degree 

 as the other carbohydrates."
