These figures point to O^-IO^ C. (3l'^-.~»0^ F.) as the most rational 

 temperature for keeping potatoes, since within these limits the respi- 

 ration is low. As soon as the sprouts begin to grow the losses of 

 organic matter increase in proi>ortion to the growth of the sprouts. It 

 is at this stage (after si)routing) that the greatest losses in the keeping 

 of potatoes occur, and tlie shorter or longer time tliat elapses befure 

 sprouting and jdaiiting the greater or less the amount of reserve 

 material in the tubers. 



Feeding shorn and unshorn lambs in -winter, T. Shaw and 

 C. A. Zavitz (Outiifio Aqr. Collrf/r E.rpt. Station Bui. No. 68, October 

 ;.'ii, J'^m, pp. S). — Tiiis experiment was with twenty lambs, and lastetl 

 from January <» to Ajtril -1», ism. Ten of the lambs had been shorn 

 the last of the previous November. The shorn lambs averaged 01.8 

 ])ounds, and the unshorn l(>l,s."» pounds eadi in weight. lioth lots 

 were kept in a elo.sed shed. Kach lot received hay ad lihitum, and 

 definite amounts of nnground oats and peas, bran, and roots, the 

 amounts being the same for both lots. Tlie total gains of the indi- 

 vidual sheep in each lot varied widely, ranging with the unshorn sheep 

 from Mi to ol pouiuls, and with the shorn from L't» t^) 70 ptainds. The 

 total gains for the two lots were practically the same, being 4L'«;.."> 

 ]»ounds t\)r the unshorn and IJ7.."» i)ounds for the shorn sheep. .V 

 calculation of the linam-ial results, ba.sed on current i)ri<-es. and vabiing 

 the hnnbs at 7 cents i)er ptiund at the close, shows the protit with the 

 ten unshorn lambs to have been .$2(;.44 and with the ten shorn laml)s

 the second lot, and no account is taken of the value <tf the wool <m the 

 unshorn lot. 



Fattening lambs for the British market, T. Shaw and C. A. 

 Zavitz [Ontario .[(jr. Collnp E.rpt. Statinn liul. Ao. i,'J, Son mix r ,', 

 l<!!il. pp. r).— Out of a lot of over .">(M» lambs purchased by the station IH) 

 were selected for winter fattening. They were all shorn October L'li 

 and 1*3, and October -4 the experiment conunenced. From this tinie 

 until November L'l they "were all<)wed to pasture on rape in the day- 

 time when the weather was fine." and received in addition hay and 

 grain composed of 7 parts by weight of oats, I i)art oat screenings. 3 

 parts peas, and 1 part bran. From November L'l until Apiil 24, the
