Book excerpt: Excerpt from Minerals Resources of Canada: Bulletin on Peat The origin of the name peat is obscure, but it is supposed to be of Uriirin Hf North German or anglosaxun extraction from a Word signifying hog mm. Or pond. As employed at present the term includes a number of sub. Stances of vegetable production, though in its restricted sense it is generally applied to the mosses of the genera um, I/ypnum', etc. when found growing together in a dense mass forming a bog in situ ations where the drainage is imperfect. These mosses, particularly the sphagnfr, cannot live except in clear, standing water and in a crowded condition, Their peculiar mode of growth, increasing the length of the f stems upwards year after year, while dying at the roots, perpetuates their existence and raises the surface of the bogs of which they form part. The sphagna hold water like a sponge, and small pools are won sionally seen in the undrained parts of the moors when these are large. The water absorbed by the mosses, of which they contain 85 to 95 per cent by weight, is wholly due to the ra'nfall, the growth ot the sp/iagrm depending upon their complete saturation. The part of the hog retaining the moisture all the year ruaud, or that from which there is the least drainage, is usually higher than the margin. Around the periphery where there is more or less seepage, or escape of the contained water, the mosses are checked in their growth and often die, the bogs in such places exhibiting dead peat. This destruction of the life of the mosses is, however, more apparent in the interior of the country where the summers are hotter and the air drier than it is along the coasts. Their healthy condition depends so much on an ample rainfall and cool summers that in dry years considerable quantities are killed. Or suffer a serious check in their growth hence the existence of so much dead peat in sinus portions of the interior. Drought and a diminished rain fall are inimic ll to the growth of pent bogs thus the central and na drained parts of the larger bogs are often higher than the. Margins.
