Alexander Wilson also contemplated nature, as nature is, and communed with her in her sanctuaries. In the forests, mountains and shores, he sought knowledge at the fountain head. The observations and records made by these collectors are the corner stones of natural history of the United States, and their writings and illustrations will be consulted when other books on the subject have passed to oblivion. Still it can not be claimed that all valuable observations have been or ever will be registered; nor that collectors did not obtain much of their vast stores of information from pioneer residents, as the acknowledgment of this fact is so often met with in their works. These authors compliment the medical profession, who in turn refer to the pioneers, students and professors in natural history--the “Squirrel Hunters.” Dr. Coues, the standard authority on ornithology of the present time, was told incidentally by a reputable woodsman, that the “wild goose” often nested in trees along large water-courses. The Doctor could scarcely believe it, and was led to investigate, and found the circumstance to be a matter of common information among the residents of localities where the bird rears its young. Captain Bindere, of the army, stationed in Oregon, states that one year it was dry and the geese all nested on the ground; and the next year proved wet with high waters, and many nested in the trees, and asks if this is instinct or reason. Other birds that usually nest on the ground, for some reason during the wet season, occasionally build in trees, showing an architectural ability entirely different from nests constructed on the ground. The writer has known the chewink, or ground-robin to build five feet from the ground a well-constructed nest, during wet seasons only. It is the observing man who resides for many years among beasts and birds that obtains full knowledge of their habits under various circumstances. It is the patient man to whom nature reveals her secrets; and the half-clad hunter is often a man versed in these hidden things, and can even tell how to “feed tadpoles to make them all females” as correctly as a Professor Drummond. Through the knowledge of such men have come the great educators--the natural history societies and associations of the north-west. Is there one of these institutions of civilization that owes not its origin to the collections, accomplishments, observations and will of the Squirrel Hunter? Not one. He not only collected scientific matter, but was also the man the future looked upon as the one to open up farms, build school-houses, churches, highways, water-courses, mills, manufactures--to carry on commerce, make laws and to enforce them. He kept his gun clean, his powder dry and bullet pouch full, ready to put down rebellion or subdue invasion, or perform any other duty assigned him.
