Your note of the Abies Douglasi suggests to me that, perhaps, it would be admissible in your journal to state that twelve to sixteen years in this country has grown the Cottonwood to a height of over forty feet, and of size sufficient to make from half to three-fourths of a cord oi wood. The black walnut, butternut, chestnut, soft maple, willows, poplars, all are rapid growers. The Norway spruce, white, and yellow, and Scotch pine have grown to a height of thirty to thirty-five feet in twelve years.

But, while we have many rapid-growing trees, promising of profit and beauty, much depends upon the soil in which they stand, and also the distances apart. Many a piece of ground, now vacant, and too low to cultivate without great expense, might be cultivated with forest trees, that in ten to twelve years would be found of greater profit than if planted in the ordinary way or left to its natural grasses. The destruction of our native forests is yearly rapidly increasing, and, perhaps, no better move could be made than to petition the controllers of public funds to apply a certain amount yearly in premiums to those who plant.
