Both parties had been long from home, and were practically without food to eat. We were obliged to stay on that island three nights and two days before the water had calmed sufficiently for us to cross the traverse. In the meantime, we had eaten the last of our supplies, and were subsisting wholly upon what blueberries we were able to find growing on the island. Some public work was about to begin up the Rainy River, and we had been informed that a steamer from Rat Portage, loaded with various articles of merchandise, was liable to come up the lake to enter the river at almost any time; consequently we were continually on the lookout for the steamer, it being the only source from which we could hope to get anything to eat, before we should arrive at Rat Portage. Finally the steamer was spied on the afternoon of the second day of our unforeseen residence on the island. With towels tied to poles, our party, hoping to be able to signal the passing steamer, went to the shore of the island. It was well out on the lake from our shore, and our hopes began to wane as we saw it steam by us, not having given us any indication that it had seen our signal. Suddenly, however, our fears were turned to hope and joy as we saw its bow turning in our direction. It made a long sweep on account of the high sea, and came in behind our island where the water was deep, and the nose of the steamer was brought almost to our shore. We quickly told the captain our plight, and asked only that we might purchase of him a little flour and a little meat, a little tea and a little coffee, sufficient to take us to Rat Portage, including a possible longer delay on the island because of the wind that was yet blowing. This he gladly gave us, refusing to accept any compensation; and with grateful hearts, we waved him adieu as the boat resumed its course. The following morning, early, the lake was quite calm; and, after a hasty breakfast, we pulled out from shore, crossed the traverse, and once more got behind the friendly islands. From this time on to Rat Portage, our journey was without special interest, the party returning together by rail to Minneapolis. CHAPTER XX. Effect of Discovery of Iron Ore on Timber Industry. During the same year that the United States government offered its lands in the northern counties of Minnesota at public auction, new interests effecting the market for pine timber were created by the discovery of iron ore of a marketable quality, near the south shore of Lake Vermilion, where now is the city of Tower, Minnesota.
