 (E. ». K., 2, p. 231 ; ."5, p. 15."); 4, pp. G7, 3 ,0; and 5, p. 109), togetlier with 

 the experinient given above on feeding growing lambs. The conclusions 

 are that: 



"(i) The average .total cost of feed reiinired to produce 1 lb. of live weight was 

 10.32 ets. and the net cost 5.34 ets. . . . 



" (2) Narrow rations, 1 : 4.7, . . . have i)roduced a greater gain in live weight than 

 wide rations, 1 : 7. 



"(3) The total co.st of feed re(iuired to 2)roduce 1 11). of live weight was about 

 the same in each case, viz, 11.3 cts. and 11.26 cts. per day. The net cost in case of 

 narrow rations was 5.51 cts. per day, against 6.49 cts. per day for wider rations. 

 This shows that the chief advantage of the verj' uari-ow rations in these experiments 

 carae from the increased value of the manure produced. 



"(4) The dry matter required to produce 1 lb. of live weight was about the 

 same in both cases, namely, 11.35 and 11.40 lbs. With the present knowledge of 

 animal nutrition, rations with a nutritive ratio of about 1 : 5 appear to be the most 

 economical to feed to growing lambs, as well as tn steers." 



Seven rations are suggested for lambs under 1 year old. 



Notes. on feeding" farm horses, J. B. Lindsey {MassacJmsctU estate 

 SUi. h'pt. lS93j pp. 170-182). — The rations fed to 3 farm liorses from 

 1888 to 1893 are tabulated, and a record is given of the live weights 

 for each month. Analyses are given of the hay, wheat bian, aud 

 provender fed. The average amounts of food given are as follows: 



nations fed to horses. 



"The so-called provender consists of cracked corn and oats mixed in the propor- 

 tion of 400 lbs of corn to 15 bu. of oats. . . . Ration 4 contains about the same 

 amount of digestible nutrients as given by Woltf for horses doing average work." 



Foods in the year two thousand ; Prof. Berthelofs theory that chemistry 

 will displace agriculture, H. J. W. D.\m (McChuc'.s Maguthte, 1SD4, Sept., pp. -WS- 

 31..').— Au account of an interview with Prof. Ijerthelot, of Pans, on the future of 

 synthetic chemistry. Prof. Berthelot maintains that several agricultural industries 

 have already been destroyed by chemistry, as, for example, the cultivation of mad- 

 der root foraliz rin for coloring, aud others are alre;idy in danger; that food nutrients 

 as fats and sugars, have already been prepared s-nthetically from their elements; 

 and tliiit it is quite prob:ible the preparation of others will follow, until ultimately 

 all food materials, beverages, condiments, tobacco, etc., will be made artificially by 

 proces.ses reveabd by chemistry instead of from natural products.
