 ma ri/.cd resiardinj; the condition of the swine industry in the various counties

 .sunuuer feeding is estimated to be $4.")! per hundredweight and winter feeding

 with comfortable quarters and roots the cost of feeding is no greater in winter 

 than in sunuuer."

 ments with Tamworth, Yorkshire, Poland China, and Duroc Jersey pigs and the

Poultry (\QH(irl.^ Rpt. W. Va. Bd. Afjr., 1906, No. 2, pp. 159, figs. 38).— 

 Articles by a number of writers on various topics connected with poultry rais- 

 ing are uicluded in this report, as well as a summai-y of experiment station 

 work on the subject, one of the articles being by K. C. Atkeson on white guinea 

 fowls {])[). 40. 41). It is stated on the basis of personal experience that this 

 variety is more satisfactory than other varieties, since they are tamer and lay in 

 the chicken house instead of seeking out-of-the-way nests, while they are par- 

 ticularly satisfactory for table fowls. 



" The young guinea does not require as much care as the turkey, Imt if liatched 

 early will reciuire more care than chickens. June [in West Virginia] is al)out 

 the best month to have them hatch, and if they are kept contined for the first 

 few days so that they will not exercise too mucli. they will get along all right as 

 they are exceptionally free from disease."
