Into this basin a quart or more of water was poured, and into the water the prescribed quantity of baking powder was stirred and allowed to effervesce. We now understood the secret of John's failures, and gave him instructions on the use of baking powder. After this we enjoyed better bread.
A week had now passed since leaving the end of the long portage out of Black Lake, and during that time we had made only about eighty miles. This was a slow rate of travel, and if possible would have to be improved on. One day had been lost in discovering the outlet from Wolverine Lake, another spent in ascending the river, and considerable time had been occupied on the several portages.
Sunday, the 16th of July, was spent quietly and profitably at camp after the six days of hard travel, and, strange to say, the flies which had filled the air and made our lives a burden the previous evening had now almost entirely disappeared. The day was bright and warm, affording a good opportunity for lake bathing. This pleasure was highly prized. After one has been subjected to the continual lacerations and stings of flies and mosquitos, and the liberal application of tar-oil for a week or two, a bath is not only a luxury, but a necessity.
On Monday morning the exploration of Selwyn Lake was continued. The shore-line was still found to be irregular and indented by deep bays. Some of these were passed by, but those toward the north end of the lake were carefully examined to their extremities, in our search for the portage, of which we had been informed, leading over the Height of Land.
