There are a great many species of pine trees. The seeds of some are large and sweet and are sold as pine nuts. These trees do not grow in this country, however, and we should have to go to South America, or to Asia, or western Europe to find pine trees from which we could gather nuts.

Squirrels gather nuts from all the pine trees, however, for they are not as particular as we, and think them all good. They are very clever at gathering cones, gnawing off the scales and getting out the seeds.

Pine trees, like the maples and elms, have two kinds of—not exactly flowers, but something answering to them. The ovules, or young seeds, are borne under the scales of the cones, and the stamens are in catkins. Sometimes these catkins are very large, and they bear a great deal of pollen which the wind carries to the cones.

A pine forest is always a sweet and delightful place. When the sun shines on the trees they fill the air with fragrance.

Pine trees used to grow all over the northern part of the United States, but they make very valuable timber, and so have been carelessly cut down and the forests destroyed, until now in many places there are almost no pine trees left.

This was a great mistake, as the people now know. The white pine of the North gave a soft white wood that could be easily carved or “turned,” and it was used more extensively than any other wood as long as the forests lasted.

A large part of the South is still covered by forests of yellow pine, whose wood is dark, hard, and valuable for building purposes.

The pine forests of the South also yield large quantities of tar, resin, and turpentine, and it is sad to see the forests being carelessly destroyed each year. The trees are cut for their sap, from which turpentine and other products are made, but if the same trees are cut three years in succession they die.
