THE METAL PENS OF 1823.--In a badly-constructed and unsanitary manufactory (Mr. James Collins's), at the back of 119 Suffolk Street, (Birm.), I witnessed the process of making silver and steel pens. As both metals were manufactured in the same manner, one description will serve. It will be remembered by a few that at that time there was a patent silver pencil case somewhat extensively manufactured, which in addition to the pencil, had a penknife, pen and toothpick provided.
