hed up by boulders driven by icealong the bank. Good examples of this were seen on the Nagagami.Ice action is also seen on the trees where the bark is torn off some-times 15 feet above the summer level of the water. In many of the lakes ridges of boulders are piled up along theshore, especially on points. Some of these walls reach a height of sixfeet or more, and sometimes contain large boulders; they are un-doubtedly formed by recent ice action. Landslides along the rivers are common, but they are usuallysmall and occur only where there are high, sloping banks. One ofconsiderable extent, and which seemed to be an exceptional case wasnoted on the Kebinakagami river twelve miles from its mouth. Atthis point the land is level and the bank rises 20 feet above the river.For ten chains along the bank the ground for five chains back hadmoved forward into the river, completely damming it for a time.The water has gradually cut channels through it, leaving large massesof the clay well exposed.

-p. 33 ALGOMA AND THUNDER BAT DISTRICTS 33 AGRICULTURAL LAND. Large areas in the country included in this report are coveredhy good clay soil, and where the slope is steep enough to afford gooddrainage the land is of excellent quality for agricultural purposes.The best area lies between the height-of-land plateau and the sedi-mentary rocks on the Hudson Bay slope. North of this the land iscomparatively level and the drainage is not sufficient to carry off thesurplus water, so that much of the ground is deeply moss covered. FLORA AND FAUNA. As already noted spruce trees up to 2 feet diameter grow alongthe streams and on some of the drier ground, and poplar up to 15is not uncommon where the conditions are favourable. But thegreater part of the area examined is covered with trees of muchsmaller growth. The most valuable timber commercially is the spruce,which grows abundantly in swamps and averages from 6 to 12diameter. Usually these trees are high, and carry their size up 40feet or more
