Quercus Phellos And Q. Falcata

To J. M. I answer, that there is a large Willow Oak on the east side of the Woodlands, near the southwest corner of the alms house, and three Spanish Oaks in the Woodlands, two or three hundred yards eastward of the mansion; one on the north side of Chestnut street, in front of Mr. Keene's house, near Thirty-seventh street;; and several in the Park, near the southwest corner of the bridge over Belmont Valley, that is, northeast of Horticultural Hall.

Tree Planting In Minnesota

S. D. Payne planted 100,000 trees last year, and expects to have 100 acres in all completed this season.

A Good Move

The President of the Missouri River, Fort Scott, and Gulf R. R., has made a contract with Messrs. Robert Douglass & Sons, of Waukegan, Illinois, to grow for that road 50,000 Black Walnut, 75,000 Catalpas, and 75,000 Red Cedar seedlings. These trees are to be planted on the company's land, at a point not far from Fort Scott, Kansas.

Wood Of Cerasus Serotina

An Illinois correspondent sends us a sketch of a stem of this tree which has made an average growth of three-quarters of an inch a year. The timber ought to very useful for cabinet work; though we do not think quite equal to the Wild Cherry trees, escapes of the cultivated Cherry which so abound in Pennsylvania. We wish some better name than"Wild Black Cherry" could be given this tree, as it is certain to become confused with these escapes from garden culture.

Linum Perenne

The pretty blue flax of the Rocky Mountains has hitherto been thought to be the same with the Old World Linum per-enne. Some of our earlier botanists named it Linum Lewisii. In a recent number of Sim-man's Journal Dr. Asa Gray remarks that it may possibly yet prove to be a distinct species, and to bear this name.

The American Poplars

These are in such confusion, that it becomes necessary to go over the whole subject from fresh specimens. Mr. Sereno Watson, of Cambridge, Mass., has undertaken the arduous task. It will serve horticulture as well as mere botanical science to help him all we can. Any one who can send fresh cut catkins, male or female, or good specimens of any sort, of our native kinds to him, will do us all good service.

Taking Off Potato Blossoms

A certain Dr. Booghe or Bogy, according to the newspapers, increases his"tubercles "one-fourth, by pinching off the blossoms as they open. Now four hundred instead of three hundred baskets of Murphies is worth trying for; but others besides this Bogy who have tried it assert it cannot be done. We venture the opinion that this doctor is like some others we wot of, who think out results and then publish thern as if they were facts accomplished.
