Parsons & Co.'s Nurseries

We have received a valuable bundle of new evergreen, and other trees and plants, from the reliable nurseries of Parsons & Co., at Flushing, Long Island, for experimental growth. Among them we notice Pinus Benthamiana, a new tree, of rapid growth; P. pumilio; Cunninghamia sinensis, somewhat resembling the Araucaria, but more hardy; Abies menzesii; Juniperus ericoides; Abies morinda and Douglasii, etc. etc., for which they will accept our thanks.

Parsons' New White Mignonette

This is a new variety, recently imported from Europe, and described as being vastly superior to anything yet grown. It is nearly pure white in color ; the spikes are large and beautifully shaped, and in odor exceedingly strong - one pot of it will perfume a whole house. At four of the European Exhibitions for 1870 it received the highest premium awarded to flowers. It has just been introduced into this country, and is now sold at fifty cents per packet. We will present it free to any one bringing us a new subscriber or a club.

Parti-Colered Collinsia, ( Collinsia Bicoler)

Purple and white - very pretty - six inches - should be sown with ene-half Schisanthus, to keep up the bloom till autumn.

Passion Flower

I saw one species of passion flower, very magnificent, six inches in diameter, almost globular in form, so filled up by an immense number of stamens.

Patent Tree Protector

The agent of this tree protector has exhibited a model of the apparatus intended to prevent the ascent, on the body of the tree, of the caterpillar. It consists of a varnished cotton cloth shield, in the shape of an umbrella, divided into two parts, to enable the operator to fasten it round the body of the stem; these two parts are joined by a tin catch and a rim, which go round the whole apparatus. Inside of the rim, and on the edge, is a tin trough, to be kept filled, or nearly so, with oil or turpentine. The insects ascend the body of the tree, are stopped by the projecting umbrella, when they retreat down to the oil reservoir, and are caught in it. The apparatus is simple and effective for insects that invade trees by ascending the stem. The patentee is Josiah Foster, Sandwich, Mass. Agent in Philadelphia, Wm. Denslow, 221 S. 5th St.; and he has the town and county patents for sale.

Patience

Our correspondents who have clubbed other papers through us, must allow us a reasonable time for transacting the business. Their letters often are a week behind in reaching us; then we must have three or four days here to make out lists; other publishers in the hurry of the season are sometimes delayed, and then time must be given for the mails to carry the papers back to the subscribers' post offices. Fully two weeks must be allowed, and sometimes three are unavoidable. Subscribers who would avoid interruption of their papers must remit us, two or three weeks before their subscriptions expire. We aim to be prompt as far as we are able, in our correspondence.

Pavia Calipornica

Have any of our correspondents specimens of the Californian horse-chestnut (Pavia Calif arnica), or of the Californian oak (Quercus Califomicus)?
