One of these boats, the “Western Engineer,” the first that ever touched the shore of Atchison county, was of unique construction, having been expressly built for the expedition and calculated to impress the Indians. On her bow was the exhaust pipe, made in the form of a huge serpent, with wide open mouth and tongue painted a fiery red. The steam, escaping through the mouth, made a loud, wheezing noise that could be heard for miles. The Indians recognized in it the power of the great Manitou and were overcome with fear. Cow Island has been a prominent landmark in the West from a very early period. It was discovered by the early French explorers and called by them Isle au Vache, meaning Isle of Cow or Cow Island. It was so named because a stray cow was found wandering about on the island. It is supposed that this cow was stolen by the Indians from one of the early French settlements and placed on this island to prevent her escape. There is a coincidence in the fact that the first horse and the first cow in what is now Atchison county, of which we have any record, were found in the same locality. The stray horse picked up by Lewis and Clark, mention of which is made on a preceding page of this chapter, was found almost opposite the upper end of Cow Island, on the Kansas shore. There is a tradition that the French had a trading post on Cow Island at a very early day. In 1810, John Bradbury, a renowned English botanist, made a trip up the Missouri river, and was the first scientist to make a systematic study of the plants and geological formations of this region. He touched the shore of what is now Atchison county, and in his book, “Travels in the Interior of America,” speaks about the great fertility of our soil. He shipped the specimens collected on this trip to the botanical gardens of Liverpool, and no doubt many Atchison county specimens were included in these shipments. The next year H. M. Brackenridge, another explorer, came up the Missouri and made some observations along our shore. [Illustration: Postoffice, Atchison, Kansas ]
