Mr. Siler, Osmer, near Ranch P. O. Utah Territory, writes: " In the Gardener's Monthly and Horticulturist for January, current year, on page 25, I find a question in regard to the Silver Spruce of the Rocky Mountains. I am not able to answer H's question as to the name, but with due respect, I would differ with the Editor's suppositions that the Silver Fir is either Abies Menziesii or A. En-gelmanni. It is neither, it is in appearance distinct, resembling more the Abies cancolor, for which I have often mistaken it before I became well acquainted with both trees. The Silver Fir grows only in one location that I have found in Kane county, and that is very near the east line, at the head of Peter's Cup Creek, at the east foot of the Pine Valley mountains.

"The 'well-known writer' quoted in the article above referred to, gives so good a description of the Silver Fir that I will not attempt to describe the tree, only saying that the tree grows 60 to 80 feet high, with long, straight, horizontal branches, and cone shaped. I have never found this species in fruit, but I will watch more closely for cones than I have done before and if I find them, you shall have a share of them.

"I am led to believe that the Silver Fir is Abies grandis, Lindo., but in this I may be mistaken as I have not had an opportunity of seeing the trees growing together, and as I remarked before, I have not seen the Silver Fir in fruit."

[The "well-known writer" will have enough of his attempt to give a well-known tree a new common name before he gets through. Mr. Siler however, does not distinguish between a "Fir" and a Spruce. His tree is quite likely to be Abies grandis which has a silvery stem, and is readily distinguished by this alone in Colorado, as it keeps this silvery character to quite old age. Abies concolor, also growing in the Rocky Mountains however, has the same character, and is probably but a form of the same species. - Ed. G. M.]

Verbena Rust - R. P., Indianapolis, Ind., writes: "Since I have been a reader of the Monthly I don't recollect to have seen anything about the fungus known as Verbena Rust. Is there no remedy for it? I planted out over thirty varieties of verbenas last spring; we had a very wet summer; rust attacked them, and I lost the whole lot. I procured seed and sowed early this spring; when the plants had formed the second pair of leaves I could see traces of rust. Where did that rust come from? From the soil, the atmosphere, or did it inherit it from the parent? I had nothing in the house affected with it, as I throw away every plant as soon as I can see a trace of it. I have talked with some of the florists here about it, but they differ as widely as the poles; and what says the Editor of the Monthly?"

[The Verbena Rust is a fungus, a very bad fellow. What particular kind it is, or its general history, has not been worked up yet to our knowledge, but we will try and put some of our mycologists on the track as soon as we can get some good specimens. - Ed. G. M.]
