forests, are to all appearances identical with the cones of the 

 Glauca variety, which I do not think has been noted by British 

 authors as occurring in Canada. They are of a light-fawn 

 colour and about ii-2^ inches long by i inch in width. The 

 scales are about 30 in number and about f inch broad. The 

 bracts, which are markedly longer than the scales, are in some 

 cones reflexed and in others point straight upwards. They have 

 a long, slender awn, and short lateral lobes, the inner edges of 

 which meet at an angle that is slightly less than a right-angle. 

 Externally the bracts are pubescent and have the appearance 

 of being covered with a whitish bloom. The seeds with the 

 attached wings, which are pale in colour, are together about 

 },- inch in length. The germination of the seed was satisfactory. 

 The seedlings have 5-7 cotyledons about ^-f inch long. In the 

 autumn, the seedlings ripened off their shoots very early. They 

 can be distinguished from the plants raised from the seed 

 collected in the other regions by their hard, stiff, primary leaves, 

 which are of the same length as the cotyledons, and on the upper 

 surface are of a dark-green colour similar to that of the needles 

 of the Scots pine, as well as by large ovoid (upper portion cone- 

 shaped) terminal buds, which are of a dark-brown colour and 

 covered with resin. On the upper surface of the primary leaves 

 there is a distinct median groove, and on the under surface two 

 white bands of stomata. The leaves ascend for a short distance 

 from their point of junction with the stem, and then radiate out- 

 wards drooping slightly. The terminal bud stands out pro- 

 minently from the top whorl of leaves. The colour, hardness, 

 etc., of the leaves suggest adaptation to xerophytic con- 

 ditions. 



(2) T/ic Interior Wet Belt. — This name is used in Canadian 

 forestry literature to denote the region extending from the 

 western slopes of the Monashee and Cariboo Mountains on the 

 west, to the Selkirk Divide on the east. Part of the Rocky 

 Mountains system, more especially the "western slopes, resemble 

 this region in regard to climatic conditions. 



The precipitation is fairly heavy, varying from 35 inches 

 at Craigellachie or 41 inches farther north at Quesnal, 

 about one-third of the precipitation in these regions being in 

 the form of snow, to 58 inches at Glacier where two-thirds is 

 in the form of snow. The temperature conditions are not so 

 extreme as in the Dry Belt, the summers being cooler, and the
