ferns, after many a long hunt, I have only found the Cystopteris fragilis and the Blechnum spicant, but I hear that the Pteris aquilina is also found. Snakes and mosquitoes do not appear to be known here. Coming almost direct from the tropics, one is dissatisfied with the uniformity of the foliage; indeed, foliage can hardly be written of, as the trees properly so called at this height are exclusively Coniferæ, and bear needles instead of leaves. In places there are patches of spindly aspens, which have turned a lemon-yellow, and along the streams bear-cherries, vines, and roses lighten the gulches with their variegated crimson leaves. The pines are not imposing, either from their girth or height. Their colouring is blackish-green, and though they are effective singly or in groups, they are sombre and almost funereal when densely massed, as here, along the mountain sides. The timber line is at a height of about 11,000 feet, and is singularly well defined. The most attractive tree I have seen is the silver spruce, Abies Englemanii, near of kin to what is often called the balsam-fir. Its shape and colour are both beautiful. My heart warms towards it, and I frequent all the places where I can find it. It looks as if a soft, blue, silver powder had fallen on its deep-green needles, or as if a bluish hoar-frost, which must melt at noon, were resting upon it. Anyhow, one can hardly believe that the beauty is permanent, and survives the summer heat
