Note 87 — {189} CHAP. VII.

These are larvæ of a fly (Hypoderma liniata?), the eggs of which are laid in the skins of the deer in the early part of the summer. Here they develop to the size of buckshot or larger, and those portions of the skin covering them become very thin, so that when the hide is taken off and tanned it is so full of holes, a quarter of an inch or more in diameter, as to be almost entirely useless.
