As the char acter of these changes can be best studied by daily observation throughout their whole course, and as such Opportunities are not often afforded, I preferred to create one for my purpose. In the study of botany and ornithology I have spent a good deal of leisure time in woods and fields during the past twenty years, and have always collected without gloves. I had never, however, been poisoned by ivy, although I had never specially shunned or sought contact with it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
