He can live in the damp weed in the hours when the tide is out, and has left the rocks dry. He eats sea-weed. Let us look at him. He has two little feelers. He has two wee, black eyes. He has a little snout, like a tiny pig. At the end of this snout is his little mouth. His small, dark foot has a dent in it. He puts out his wee, file-like tongue, and laps it out and in, as a dog does when he drinks water. The sharp teeth cut off little scales of weed for him to eat. Take ten or more of these little shells in your hand. Each tiny animal draws in his wee foot. As the little animals hide in this way, put down your ear, and you will hear a faint squeak. It is made by the air in the shells. LESSON XLI. REVIEW. What is a shell-fish? What three great orders of shell-fish are there? Did you say there are many kinds? Name some of the kinds.
