Experiments in pig-feeding, J. H. Connell, B. S. (pp. 3-19). — 

 These Avere preliminary experiments to test the rehitive values of 

 shelled corn, corn meal, cob meal, wheat bran and ship stuff for kee))- 

 ing and for fattening, and the various lengths of time that the feed- 

 ing may be continued with profit. Six Chester Whites, five " Thin 

 Rinds."' and one Red Berkshire, all mixed breeds, were used. The 

 details of these experiments will be included in a special bulletin on 

 pig- feeding to be issued by this Office. The results imply that fat is 

 more i-apidly produced by shelled corn, and more cheaply by corn 

 than by the other foods tested; that much corn-cob meal Avas wasted 

 in the feeding; that cotton-seed meal was unprofitable; that the 

 nitrogenous foods produced comparatively little gain in live weight, 

 but that the pigs fed on them Avere so much stronger than the others 

 that they caused the latter serious injury Avhen they were turned out 

 together; and that in the tests of nitrogenous foods a mixture of 

 corn-cob meal and ship stuff in equal parts Avas the cheapest. The 

 experience Avith cotton-seed meal Avas unsatisfactory.

Field experoients on sugar-cane (pp. 199-252). — This Station 

 is engaged in studies regarding the soil, fertilizers and methods of 

 cultui'c foi- sugai'-cane. and the manufacture of sugar. When the ex- 

 j)eriuK'nts recorded in this bulletin Aver? made the Station Avas located 

 at Kenner. The buHetiii is devoted to a record of field exi)eriments, 

 inaiidy a c(mtinuation of those of previous years, on germination and 

 growth from "plant cane" and from stubl)le under different condi- 

 tions: physiological (juestions, including influence of suckering on 

 (■aiic: \arieties best adapted to Louisiana; and manurial require- 

 ments. 



(jcnnhudloti (juestiom (pj). 199-208). — While in some sugar- 

 producing regions, as Cuba, the sugar-cane is generally groAvn 

 through a long series of years, each season from the stubble of the 

 l)revi()us season, in Louisiana frequ.ent re]~)lanting is found ne^-essary. 

 For this the cane itself is used. The (|uantity required is very large, 

 and makes an important factor of the cost of sugar production. The 

 lower part of the stalk is richest in available sugar. If the npper 

 |)art of the stalk could be conA'eniently and successfully used for
