The miller's thumb is an odd little fellow, which you may catch in brooks. The gudgeon is worthy of much more consideration; for it is a beautiful and delicious fish, affording great amusement to the young angler, and not difficult to catch. August and September are the best months to take him. The line should be all gut, with very small hooks, each baited with a worm. Don't use a float, but fasten a small bullet to the end of the line; let that just touch the bottom, and you will feel the little short jerks which indicate that the fish is tugging at the bait, or is hooked, when, not in a hurry, you draw out the litttle captive, and fill your basket in a very short time.
