Did you ever hear of a steam tricycle? In case you didn't, here's a picture of one invented by L. G. Perreaux. A reporter who wrote about it, in 1882, said Perreaux had worked 14 years to perfect the apparatus. Apparently other inventors were out for the same objectives-to develop a self-propelling tricycle for one or two persons, able to operate for several hours on steam.
We don't know what became of it, but you can read about it in a paperback book, BIKES & TRIKES OF LONG AGO, which retails for $1.25. Add 25 cents for handling and mailing. Order from Stemgas, Box 328, Lancaster, Pennsylvania 17604.
