Good doggie

One fall day Bill was out raking leaves when he noticed a hearse slowly drive by. Following the first hearse was a second hearse, which was followed by a man walking solemnly along, followed by a dog, and then about 200 men walking in single file.

Intrigued, Bill went up to the man following the second hearse and asked him who was in the first hearse.

"My wife," the man replied.

"I'm sorry," said Bill. "What happened to her?"

"My dog bit her and she died."

Bill then asked the man who was in the second hearse. The man replied, "My mother-in-law. My dog bit her and she died as well."

Bill thought about this for a while. He finally asked the man, "Can I borrow your dog?"

To which the man replied, "Get in line."

First U.S. Bessemer steel rails

In 1865, the first Bessemer steel rails ever rolled in the U.S. were a few rolled at the North Chicago Rolling Mill from hammered blooms made at the Wyandotte rolling mill from ingots of steel made at the experimental steel works at Wyandotte, Mich. The American Iron and Steel Association was in session in Chicago at that time, and several of its members witnessed the rolling of these rails. The North Chicago Rolling Mill was the first large iron and steel plant in the Chicago area, founded in 1857. The first steel rails rolled for a business order in the U.S., were made at the Cambria Iron Company, at Johnstown, Pa., in Aug 1867, from ingots manufactured at the works of the Pennsylvania Steel Company, at Harrisburg, Pa.*[Image: detail from engraving of the much larger area covered by the factory buildings.]
