Linden trees are planted for shade in many countries, and in Europe they are often cut into grotesque shapes of animals as they grow. They are clipped into hedges, as close as box or yew. In America they are usually allowed to grow naturally, as shade trees. European species are rather more symmetrical than our native kinds.
The Indians of the Northwest used the soft inner bark of the tamarack pine for food. They cut down the trees, strip them of bark, and scraped out this soft lining layer. With water, they mash it into a pulp, which they cook and then mould into large cakes. A hole is next dug in the ground, lined with stones, and a fire is built in it. When the stones are hot, all ashes are removed, and the cakes, wrapped in green skunk cabbage leaves, are laid in. A fire of damp moss is built on top, and thus the cakes are thoroughly, baked. To insure their keeping, they are next smoked in a close tent for a week or more. This dries and cures them so that they may be safely packed away for future use. These hard, dry cakes are afterward broken into pieces and boiled. When the mass softens and cools, it is ready to eat. The fat of different animals is used for butter on this strange Alaskan bread.

Everybody knows that trees bear fruits of many kinds that are useful as food for men and beasts. Spices, such as nutmegs, mace, cloves, and allspice, may be added to this list of fruits which we have as human foods.
The bark of birches is invaluable to the Indians for the making of their canoes, baskets, and all kinds of utensils. Huts and teepees are walled with it. Rope and coarse cloth are made out of the fibre of mulberry bark, and berry baskets out of the bark of the lodgepole pine. The fibrous roots of the larch tree furnished tough thread, with which the Indians sewed canoes of birch, and they made them water-tight with the gum of the balsam. The brown gum that oozes from wounds of the Western larch is sweet and starchy. The Indians discovered in it a valuable article of food.
One of the latest uses of wood is the making of paper, although the white hornet showed in its conical paper nest that this could be done. She has been making wooden paper for hundreds of years, scraping the wood from the surface of weathern-worn fence boards, and from the dead limbs of forest trees. Our newspapers are made of ground wood, cooked to a soft pulp, and rolled out into thin sheets. The high price of paper makes it worth while to gather up papers, bleach them, convert them into pulp, and roll them out again into sheets. Spruce wood and poplar are among the cheap woods which have come into demand at the paper mills. The forests of these trees, counted of little use for lumber, have become valuable because the paper mills can use them.
Look about the room, and a dozen articles, beside the chairs and table, are products of wood, or in some way owe a debt to trees. The paint that covers the window sash and frames was mixed with turpentine, which is obtained from the pitchy sap of pine trees. The shades and curtains are coloured. Dyes of many kinds are extracted from the various dyewoods, trees that grow in tropical forests. The newspaper and the books on the shelves are made of wood pulp. The lacquered box from Japan is a handsome thing. The lacquer varnish is the sap of a certain Oriental sumach tree. The perfume of the gloves in the box is made from the fragrant gum of an Oriental sweet gum tree. The skin out of which the gloves were made was tanned, not with bark, but with the acorn cups, or galls, of a European oak.
