August Twenty-second
The fresh-water clam furnishes us with a good quality of pearl, and from the shells pearl buttons are made. Along the muddy bottom of our inland lakes and rivers, you may see the clumsy writing in the mud where they have crawled. During a clam's infancy it lives a parasitic life, embedded in the body of a fish. It then emerges and drops to the bottom of the lake or river, where it spends the remainder of its life.
