This case I lined nicely with silk

M. A. B. KellyLeaves from Nature’s Story Book, vol. II, Boston, Educational Publishing Company, 1893, p. 54.

« I ought to have said, that all this time  I was hidden in a small tube-case that I had made for myself, of bits of stems, wood, sand, and little stones.

This case I lined nicely with silk; and as I could put my head out at one end and my feet out at the other, I had no trouble in crawling about for foud. »
