Polygonum Amphibium For Tanning

Some years since we noted that this plant has good tanning properties. The Kansas City Science Review says that gentlemen of that city are prepared to put the discovery into practical operation. It is said to have three times the amount of tannin that an equal weight of oak or hemlock has. One advantage will be that the de struction of forests will not interfere with the supply.

An Old White Pine

A tree of remarkable dimensions was felled recently a Crystal Spring, Yates County, New York. The tree was perfectly sound and vigorous, thirteen feet in circumference at the ground, and nearly two hundred feet in height. The "rings" on its stump indicate an age of three hundred and fifteen years, and it is estimated that 4,000 feet of lumber will be cut from its trunk.

Michigan Forests

According, to Wheeler and Smith's catalogue, "the annual production of pine lumber in Michigan, for the last decade, has exceeded 2,000,000,000 feet. Yet, in spite of this enormous consumption, it is safe to say that Michigan still contains more valuable pine than any like area in North America. The lumber interest alone enriches the State something like $40,000,000 a year.'"

Size Of Honey. Locust

An Ohio correspondent asks: "How large does the Honey Locust grow? I saw two trees a few days ago in a river bottom in Hardin Co., 0 , over twenty inches in diameter, and thought they were the largest I had ever seen".

[This is very well, but it is but an average growth for Pennsylvania. Without having the exact figures to hand, cases are surely known exceeding this. - Ed. G. M].

Dr. Parry

This botanist to whom we already owe so many new discoveries in our country, has just returned from another expedition, and with some more novelties as we are informed.

Yellow Choke Cherry

The editor of the Le Journal d'Agriculture Illustre, of Montreal, kindly furnishes the following note :

"I have seen Yellow Choke Cherries several times in the Province of Quebec. The ' Cerise a grappe ' is very common here, and some of the fruit, when dead-ripe, is by no means to be despised".

Insects Injurious To Forest And Shade Trees

By A. S. Packard, Jr., Bulletin No. 7 of the United States Entomological Commission, issued by the Department of the Interior.

This is another of the admirable series which do so much credit to the United States Government, and is of so much scientific value to practical culturists. Almost all the familiar insect troubles are exposed - some few overlooked. The ash-borer is one of these, though it is not the troublesome creature other insects are.
