Although in the California Sierras this noble tree attains a height of between 200 and 300 feet, and a diameter of trunk of 10 to 20 feet, here in the the east it betrays no sign of the vast proportions it assumes in its western mountain home. We have some nice young trees of it, and they are healthy and look well, but they display no inclination whatever to quick growth, in fact, rather the contrary. Evidently they are unhappy here.

Pinus flexilis we have got and it gets along nicely, but has more of an inclination to spread horizontally than rise perpendicularly. But probably your correspondent refers to the true P. albicaulis (P. flexilis var. albicaulis, Bot. Cal. II. 124), which we have not got.

Pinus monophylla is probably the "Fremont's Nut Pine" referred to. We have it, but it is unhappy, that is, it makes very little growth. And as I saw it in the gardens of G. W. Childs, at Bryn Mawr, Philadelphia, it is no better. On the other hand, Andrew S. Fuller, of Ridgewood, N. J., tells me it grows quite vigorously in bis grounds.
