re referred to would I was quite aware be utterly worthlessfor boring through rock, but I did not expect to meet with any beds of solid rock, over-lying the lignite in this territory, nor did we do so in any of the holes put down thisseason. In drift or loose material, moderately dry, and comparatively free from stones,whether of sand or clay, or an admixture of the two, it answered all that could be expectedof such a tool. But in coarse gravel or drift containing many boulders or stones, it wasall out useless. On the river bottom at the Big rapids we found after repeated attempts that it wasimpossible to bore down to the bed of lignite with the auger. About 1 7 feet was thegreatest depth attained. In this and other holes, the auger came upon stones of suchsize that we had to desist for fear of breaking it. Three or four cuts were however made into the bank from the river. Theseare shown upon the plan or survey of this point, as also in the photograph whicli accom-pany this report. 64
