At the beginning of tlie grazing season 20 lambs in a pasture of average size 

 were market! in order to compare tbeir growth with an equal number of lambs 

 belonging to a herded band. After being handled under the pasturage system 

 for 3 months, between the ages of 3 and months, the lambs weighed 8 lbs. 

 more than the best lambs of the same class that had been herded ; the loss 

 from the pastured band during the 3 months was 0.5 per cent as against 3 per 

 cent from bands herded on outside range, and the pasturage system gave a 

 heavier and cleaner wool. crop. 



" It is safe to conclude that range grazed under the pasturage system will 

 carry 50 per cent more sheep than when grazed under the herding system, where 

 the band is driven. to and from camp each day. Whether the increase in carry- 

 ing capacity is greater than 50 per cent will depend chiefly upon the herder, 

 but in part upon the character of the forage crop." 



There is a financial statement concerning the economic value of maintaining 

 this pasture, and also a brief report on a successful coyote-proof pasture owned 

 by a private individual. 



[Feeding- experiments], F. W. Taylor {IS! etc Hampshire Sta. Rpts. 1907-8, 

 pp. 322-32.'f figs. 6. ) — Two lots of 4 yearlings and 4 aged ewes each were used to 

 compare molasses with corn meal as a supplementary ration. The basal ration 

 consisted of middlings, oats, and second crop clover. The experiment lasted 

 GO days. The lot which received the molasses made a daily gain 1.4 times that 

 fed the cornmeal and the gain was made 1.5 times cheaper for each pound of 

 gain. 



In another experiment 15 shoats were divided into 5 lots and fed for 35 days. 

 On soaked shelled corn there was a gain of 82.2 lbs., at a cost of 7.3 cts. per 

 pound ; on shelled corn and skim milk a gain of 141 lbs., at a cost of 7.4 cts. 

 per pound ; on shelled corn and middlings a gain of 99.3 lbs., at a cost of 8.9 cts. 

 per pound ; on shelled corn, middlings, and skim milk a gain of 1.29 lbs., at a cost 

 of 8.2 cts. per pound ; and on shelled corn, middlings, and molasses a gain of 

 104.7 lbs., at a cost of 8.89 cts. per pound. 



On the size of the body and its relation to the size and development of the 

 lungs and heart of two breeds of sheep, A. Seeberger (Jalirb. Wiss. u. Prakt. 

 TierzucM, 4 {1909), pp. LXXIV-CXY). — Body measurements- and weights are 

 given on the Southdown and Franken breeds of sheep. 



The Southdowns were larger in all dimensions except depth of chest and 

 height from the ground to the point of the ulna. The average live weight of 

 75 Southdowns was 47.5 kg., dressed weight 28.8 kg., lung weight 559.5 gm., and 

 heart weight 195 gm. The corresponding averages for 75 Franken sheep w^ere 

 live weight 49.3 kg., dressed weight 24.8 kg., lung weight 045.3 gm., and heart 

 weight 218.4 gm. The author concludes that a thoracic cavity with a large 

 index, that is, a larger breadth, is correlated with a smaller lung. 



A bibliography of the literature on the subject is appended. 



Dried potatoes and corn for fattening- swine, O. Kellner et al. {Ber. Landtr. 

 Reichsamte Innern {Germany^, No. 11, pp. 55-8S; 12, pp. 227). — A report of 

 cooperative feeding trials with potato chips, potato flakes, and ground corn at 

 16 farms and experiment stations. Most of the trials lasted from 80 to 100 

 days, and nearly 400 animals were used. 



In all cases good results were obtained with potato flakes and potato chips, 

 but the corn-fed animals produced a slightly better quality of flesh. The aver- 

 age daily gain per head in 7 experiments lasting about 100 days and involving 

 210 animals was on the corn ration 0.624 kg., potato flakes 0.63 kg., and potato 

 chips 0.598 kg.' In 8 other experiments the corresponding gain with the flakes 

 was 0.665 kg. and with the chips 0.6 kg. As a result of all the experiments it 

 is concluded that the best amount to feed is from 20 kg. to 29 kg. of flakes or
