H. V. Hart-Davis, Chats on Angling
“ We have often tried for him, but the pace of the stream between us, stand where we will, has always beaten us: no sooner has our well-cocked fly sailed into the head of the glide than it is hurried across it, leaving a most unnatural trail, or wake, behind it such as no living insect ever made. This trail of the serpent, or "drag" as it is called, is one of the greatest difficulties that we have to cope with in angling with the floating fly. ”
