The summer of 1851 came, which brought great changes, and prepared the way for others. It was one of the very wet summers in Minnesota, when the streams were flooded all the summer through. In making our trip for provisions in the spring, we were detained at the crossing of one stream for almost a whole week. In the latter part of June, the Indians from all along the upper part of the Minnesota were called down to Traverse des Sioux, to meet commissioners of the government. They were obliged to swim at many places. The Minnesota was very high, spreading its waters over all the low bottom contiguous to the mission premises. Governor Ramsay and Commissioner Lea were there for the government. General Sibley and the fur-traders generally were present, with a large number of the Wahpaton and Sisseton Sioux. The Fourth of July was to be celebrated grandly, and Mr. Hopkins had consented to take a part in the celebration, but the Lord disposed otherwise. In the early morning, Mr. Hopkins went to bathe in the overflow of the river. When the family breakfast was ready he had not returned. He was sought for, and his clothes alone were found. He had gone up through the flood of water. It was supposed that, unintentionally, he had waded in beyond his depth, and, as he could not swim, was unable again to reach the land. This was the second great sorrow that came, in the same way, to the mission band of Traverse des Sioux. It threw a pall over the festivities of the day. The Indians said again the Oonktehe--their Neptune--was angry and had taken the _wechasta wakan_. But the mission families were enabled to say, "It is the Lord." When the body floated it was caught in fishing nets, and carefully taken up and buried by the "Oaks of Weeping." Mr. Hopkins did not live to see much matured fruit of his labors, but he had put in eight years of good, honest work for the Master, among the Dakotas, and he has his reward. The Treaty was made, which, with one consummated immediately after, at Mendota, with the Lower Sioux, conveyed to the white people all their land in Minnesota, except a reserve on the upper part of the river. These treaties had an important bearing on our mission work and on all the eastern Dakotas.
