Bombyx Mori, however, this is impossible, the climate and 
the food being the obstacles. 
Although this estimate for adult labour is made accord- 
ing to the foreign rate of wages, I think it might be 
very considerably lessened, as is the case in factories, by 
employing children. If, then, some of the elder children of 
the agricultural labourers were properly instructed in the 
business, they could perform all the necessary duties 
required. The great point to enforce would be punctuality 
in attendance, supply of fresh food, and cleanliness. 
This might be accomplished by giving, in addition to the 
daily wages, a slight per centage for every 100 cocoons 
fully completed, which would make it the interest of the 
young labourers to increase by all the means in their power 
the number of cocoons. " With the cultivation of the 
Bicinus Silk," says Kaufmann, "it is far different. While 
the former must be content with one brood in a year, the 
latter can have from 8 to 12 ; and, granting that the 
expenses in each case are alike, the cultivator in the latter 
case is in a position to turn his capital some 8 or 12 times as 
often, and is, of course, able to afford his article at a much 
more reasonable rate. There will also be a comparative 
diminution of all outgoings, owing to there being no loss 
from intermission ; to the management being less expensive ; 
and to the very low value of the food. From all these 
circumstances it will be apparent that the Eicinus Silk must 
claim to be ranked among the cheapest of the textile sub- 
stances. That it never can be dear is also evident from the 
fact that carding is found to be the most eligible mode of 
treating the cocoons ; from which, in all cases, the moths 
may be allowed to escape, whilst the breeder looks for his 
profit to the quantity rather than the quality. 
" As regards the silk produced from the different species of 
moth, none of these equal that of the Bombyx Mori, for
