Philadelphia: Campbell & Pepper, Publishers. Nothing shows better the rapid growth of the silk industry than the establishment of a monthly magazine, expressly in its interest. We hope, as we believe, the present venture will prove a good success.
Many wonder why the raw silk so often presents varied colors. The following from this magazine may give the clue:
" By feeding silk-worms during the last twenty days of the larva stage, on vine leaves, a Frenchman has produced magnificent red cocoons; by pursuing the same course, using lettuce, he obtained them of a deep emerald green. Others of a beautiful yellow, fine green, and violet, were produced by the same mode, using white nettle for food." Sometimes the silk is dyed but it is always best if the color is more natural.
