(1) =Peat.=—Few trees will succeed well on an unreclaimed peat bog, but, where draining and soiling have been attended to at the outset, the number that grow and produce a fair amount of valuable timber is almost without limit among our generally cultivated species. Among conifers that have proved themselves suitable for bog planting are the larch, Scotch pine, and common and black spruces (_Picea excelsa_ and _P. nigra_). The larch grows rapidly, and is less subject to disease on peaty than any other soil—indeed, up to a few years ago, I cannot remember having seen a trace of any of the diseases which have rendered the life of the tree so precarious of late years in this country. In thinning a larch plantation of fully sixty years’ growth I found the trees felled to be perfectly healthy, and of exceptional quality, with, on an average, 72 ft. of wood in each. The subsoil in this case was clay, and the bog, previous to being planted, had been cut over for fuel. The Scotch pine grows almost as freely as the larch—the average in over fifty trees measured being about an eighth less—under similar conditions. Natural reproduction of the Scotch pine goes on so rapidly that it must be considered one of the very best trees for planting on peat bog. The spruces are excellent trees for planting on reclaimed peat bog, where they produce a fair amount of timber and afford excellent shelter to other trees. Of hardwoods, the beech is one of the best for bog planting, as it grows rapidly and produces a large amount of clean timber. The alder grows luxuriously on peaty soils, and shows no traces of disease or canker. Another excellent bog tree is the Gean or Wild Cherry, and this may likewise be said of the holly. Ash and oak are not generally of large size, nor are they always healthy on peat bog, even when it has received a great amount of attention in the way of reclaiming. Birch, lime and poplar of various kinds are all suited for planting on well-drained bog. Among coniferous trees, a large number are well suited for planting in reclaimed peat bog. By way of experiment I have planted specimens of various kinds in newly-formed plantations, and in nearly every case the trees have grown well, particularly when partially sheltered. _Cupressus macrocarpa_ is one of the best, and not one whit behind it are _C. Lawsoniana_ and _C. goveniana_. _Wellingtonia gigantea_ and _Sequoia sempervirens_ have done well, while _Pinus laricio_ and _P. austriaca_ grow freely. I find that the majority of the recently introduced conifers do well on prepared peat bog—that is, where a quantity of loam has been incorporated with the bog and all superfluous moisture drained away.
