There is one race of trees, the willow, very common about us, that is so universally subject to this pollarding, for the purpose of providing stakes and hurdles for the farm, that probably few persons have ever seen a willow tree. At any rate a sight of one grown unmutilated from the root is a rare occurrence. The few that I have seen constituted trees of great beauty; but as the willow, from the nature of its wood, can never be valuable as a timber tree, perhaps by topping it we obtain its best services. In the county of Gloucester there are several remarkable trees of different species now growing, but I am not acquainted with any greater natural curiosity of this sort than an uncommonly fine willow tree in the meadows on the right of the Spa-house at Gloucester. There are two of them; the species I forget, but one tree is so healthy and finely grown, that it deserves every attention, and should be preserved as a unique specimen, an example of what magnitude this despised race may attain when suffered to proceed in its own unrestrained vigor. Dec. 30.—A cold foggy morning, the ground covered with a white frost; about twelve o’clock the sun burst out with great brilliancy, and life and light succeeded to torpor and gloom; a steam immediately arose from our garden beds and plowed lands, giving us a very strong example of the rapid manner in which the matter of heat (caloric) will at times unite with water. Half an hour before, this water was frozen and inert; but the instant that the sun’s rays fell upon it, their heat was imbibed, and the icy matter converted into a body lighter than the atmosphere by which it was surrounded, and passed into it in the vapor we have just noticed. I was the more particular in observing this common event, as it afforded a forcible illustration of the invisible evaporation which is constantly going forward, the unremitting changes in operation, the action and reaction of the earth and its products with the atmosphere. During the night, and the earlier parts of the morning, water was falling on the earth in minute particles, constituting what we call fog; then out burst the sun, and reclaimed this moisture which had fallen, and we could see it obeying the mandate, and pass away in steam. In the evening it will probably return again in fog, or in rain, when the atmosphere cools; and thus a constant visible intelligence is going on. How much insensible intercourse takes place we know not, but we can comprehend its agency by the effects and events that manifest themselves. Our country people think these “rokings” (reekings) of the earth greatly favorable to the growth of vegetation, supposing it occasioned by the internal heat of the earth producing a vapor like that from fermenting soil, thus warming the roots; but if the theory be defective, the fact may be true, by the caloric in the sun’s rays promoting the decomposition of the water, or separating the component
