Questions re-garding the best conditions of soil and climate have beenfully solved, and it would be possible to obtain one qualityalways quite similar in results by nourishing the wormsfrom extensive and well-kept mulberry orchards. Unfor-tunately, modern filatures are always in the habit of mixingcocoons according to their appearance and reeling percent-age, not according to their rearing. I have noticed often. 16 Raw Silk that in almost every country, filatures under pressure fromunavoidable causes, import cocoons, of other countries orprovinces to be reeled alone or mixed with local cocoons. When the crop of Cevennes cocoons is short, good Ital-ians or Syrians make up the shortage. The silks are soldas second choices only, and cannot compare v/ith the silksspun from real Cevennes, although reeled by the same ex-perienced hands. In Japan it is common for cocoons ffomBushu to be reeled in Sinshiu, and vice versa. I may note in passing a curious occurrence which hap-pened in Japan during the latter part of the season crop was too small for the large American demand andprices were pushed up to yen 1,400 for No. V/2 Kansai.
