An Inscription Problem

According to the Knight-Ridder News Service, the inscription on the metal bands used by the U.S. Department of the Interior to tag migratory birds has been changed. The bands used to bear the address of the Washington Biological Survey, abbreviated, "Wash. Biol. Surv." until the agency received the following letter from an Arkansas camper:
"Dear Sirs: While camping last week I shot one of your birds. I think it was a crow. I followed the cooking instructions on the leg tag and I want to tell you it was horrible."

U.S. Patent No. 1

In 1836, John Ruggles of Thomaston, Maine received patent Number 1 from the U.S. Patent Office, under a new system for numbering patents. Before Ruggles, there had been 9,957 non-numbered patents issued. Ruggles received his patent for a traction wheel used in locomotive steam engines. He was Chairman of the Committee on Patents of the U.S. Senate, and was instrumental in patent law reform. However, in 1838, a Senate select committee investigated corruption charges against Senator Ruggles relating to a patent application.
