Much astonishment was expressed by those of the party who were aware of Schoolcraft's expedition in 1832, that he should have missed finding this lake so closely connected with Itasca, and various were the surmises as to the cause of this remarkable oversight. One plausible suggestion was, that the rushes and reeds had so obstructed the entrance of the stream into Itasca, that not having a previous knowledge of its whereabouts, there was nothing surprising in its being overlooked. By far the most probable theory, however, was advanced by Captain Glazier, who stated, quoting Schoolcraft himself as authority, that when he reached Itasca he was too much hurried to make a thorough exploration. He had made an engagement to meet some Indians in council at the mouth of the Crow-Wing River, fully seven days' journey from this point, and he had not more than the seven days to accomplish it. Accordingly, as his mind had been prepared by his guides all along to accept Itasca as the true source, he only stopped long enough to see and hurriedly coast the lake, and then returned to the Indian council on Crow-Wing River. This is Schoolcraft's own statement, and there can be no doubt that it is the true reason for his failure to locate the source correctly. He never saw the beautiful lake to the south of Itasca, fed by the springs and streams of the marshes which give birth to the Infant Mississippi. Therefore, he could not know that Itasca was but an expansion of the stream, like other lakes in its onward course, a sudden growth, as it were, which gave promise of the vast proportions the mighty giant would hereafter assume. There would be something almost sad in his coming so near and yet missing the mark at which he had aimed, if it were not that he lived and _died_ in the belief that he was right in his assertion that the great Father of Waters rose in the lake which he, oddly enough, named Itasca. Oddly, because Itasca is a name given by the Indians to the mysteries of their religion and necromantic arts, and Schoolcraft, by his decided statements in regard to the lake, succeeded in enveloping in mystery the true source for another fifty years. Why it should _ever_ have been a mystery is a question often raised; but there can be no doubt that it is owing to the fact that no fur traders and but few Indians ever penetrate the boggy, swampy, lake-covered regions of Northern Minnesota.
