A mechanic living in Jamestown, New York State, has constructed a perfect locomotive, which is said to be the smallest in the world. The engine is only eight and a quarter inches in length, with a tender ten inches long. The pumps throw one drop of water per stroke. As many as 585 screws were required to put the parts together. The engine itself weighs one and a half pounds, and the tender two pounds and two and a half ounces. The mechanic was at work on the locomotive for eight years, though intervals of time only were given to the labor of constructing it.
