Har. Wooden walls? that’s odd. I should think stone-walls better; for wooden ones might be set on fire.
Tut. True: but the meaning was, that as Athens was a place of great trade, and its people were skilled in maritime affairs, they ought to trust to their ships. Well, this is the case with Great Britain. As it is an island, it has no need of walls and fortifications, while it possesses ships to keep all enemies at a distance. Now, we have the greatest and finest navy in the world, by which we both defend ourselves, and attack other nations, when they insult us; and this is all built of oak.
Geo. Would no other wood do to build ships?
Tut. None nearly so well, especially for men-of-war; for it is the stoutest and strongest wood we have; and, therefore, best fitted, both to keep sound under water, and to bear the blows and shocks of the waves, and the terrible strokes of cannon-balls. It is a peculiar excellence for this last purpose, that oak is not so liable to splinter or shiver as other woods, so that a ball can pass through it without making a large hole. Did you never hear the old song,
Hearts of oak are our ships, hearts of oak are our men, &c.?
Geo. No.
Tut. It was made at a time when England was more successful in war than had ever before been known, and our success was properly attributed chiefly to our fleet, the great support of which is the British oak so I hope you will look upon oaks with due respect.
Har. Yes; it shall always be my favourite tree.
Tut. Had not Pope reason, when he said, in his Windsor Forest,
“Let India boast her plants, nor envy we
The weeping amber, or the balmy tree,
While by our oaks the precious loads are borne,
And realms commanded which those trees adorn!”
These lines refer to its use as well for merchant-ships as for men-of-war; and, in fact, all our ships are for the most part built either of native or foreign oak.
Geo. Are the masts of ships made of oak?
Tut. No; it would be too heavy. Besides, it would not be easy to find trunks of oak long and straight enough for that purpose. They are made of various sorts of fir or pine, which grow very tall and taper.
Geo. Is oak wood used for anything besides ship-building?
Tut. O yes; it is one of the principal woods of the carpenter, being employed wherever great strength and durability are required. It is used for door and window frames, and the beams that are laid in walls to strengthen them. Floors and staircases are sometimes made with it; and in old houses in the country, which were built when oak was more plentiful than at present, almost all the timber about them was oak. It is also occasionally used for furniture, as tables, chairs, drawers, and bedsteads; though mahogany has now much taken its place for the better sort of goods, and the lighter and softer woods for the cheaper; for the hardness of oak renders it difficult and expensive to work. It is still, however, the chief material used in mill-work, in bridge and water works, for wagon and cart bodies, for threshing-floors, for large casks and tubs, and for the last piece of furniture a man has occasion for. What is that, do you think, George?
Geo. I don’t know.
Har. A coffin.
Tut. So it is.
Har. But why should that be made of such strong wood?
Tut. There can be no other reason than that weak attachment we are apt to have for our bodies when we are done with them, which has made men in various countries desirous of keeping them as long as possible from decay. But I have not yet done with the uses of the oak. Were either of you ever in a tanner’s yard?
Geo. We often go by one at the end of the town; but we dare not go in for fear of the great dog.
Tut. But he is always chained in the daytime.
Har. Yes; but he barks so loud and looks so fierce, that we were afraid he would break his chain.
Tut. I doubt you are a couple of cowards. However, I suppose you came near enough to observe great stacks of bark in the yard.
Geo. O yes; there are several.
Tut. Those are oak-bark, and it is used in tanning the hides.
Har. What does it do to them?
Tut. I’ll tell you. The hide, when taken from the animal, after being steeped in lime and water to get off the hair and grease, is put to soak in a liquor made by steeping oak-bark in water. This liquor is strongly astringent, or binding, and has the property of converting skin into leather. The change which the hide thus undergoes renders it at the same time less liable to decay, and soft and pliable when dry; for raw skins, by drying, acquire nearly the hardness and consistence of horn. Other things are also tanned for the purpose of preserving them, as fishing-nets and boat-sails. This use of the bark of the oak makes it a very valuable commodity; and you may see people in the woods carefully stripping the oaks when cut down, and piling up the bark in heaps.
Geo. I have seen such heaps of bark, but I thought they were only to burn.
Tut. No; they are much too valuable for that. Well, but I have another use of the oak to mention, and that is in dying.
Har. Dying! I wonder what colour it can die?
Tut. Oak sawdust is a principal ingredient in dying fustians. By various mixtures and management it is made to give them all the different shades of drab and brown. Then, all the parts of the oak, like all other astringent vegetables, produce a dark blue or black by the addition of any preparation of iron. The bark is sometimes used in this way for dying black. And did you never see what the boys call an oak-apple?
Geo. Yes; I have gathered them myself.
Tut. Do you know what they are?
Geo. I thought they were the fruit of the oak.
Tut. No; I have told you that the acorns are the fruits. These are excrescences formed by an insect.
Geo. An insect! how can they make such a thing?
Tut. It is a sort of fly, that has the power of piercing the outer skin of the oak boughs, under which it lays its eggs. The part then swells into a kind of ball, and the young insects, when hatched, eat their way out. Well this ball or apple is a pretty strong astringent, and is sometimes used in dying black. But in the warm countries there is a species of oak which bears round excrescences of the same kind, called galls, which become hard, and are the strongest astringents known. They are the principal ingredients in the black dies, and common ink is made with them, together with a substance called green vitriol, or copperas, which contains iron.
I have now told you the chief uses that I can recollect of the oak; and these are so important, that whoever drops an acorn into the ground, and takes proper care of it when it comes up, may be said to be a benefactor to his country. Besides, no sight can be more beautiful and majestic than a fine oak-wood. It is an ornament fit for the habitation of the first nobleman in the land.
Har. I wonder, then, that all rich gentlemen who have ground enough do not cover it with oaks.
Tut. Many of them, especially of late years, have made great plantations of these trees. But all soils do not suit them; and then there is another circumstance which prevents many from being at this trouble and expense, which is the long time an oak takes in growing, so that no person can reasonably expect to profit by those of his own planting. An oak of fifty years is greatly short of its full growth, and they are scarcely arrived at perfection under a century. However, it is our
