"But there isn't very much red about it, after all," said Malcolm.

"It wasn't red," murmured Edith; "it was green;" and the next moment "the baby" was fast asleep, but Miss Harson was afraid that she had taken the snake with her to the land of Nod, so restless was her sleep.

"I hope the yellow birch is yellow," said Clara again.

"We will see what is said of its color," replied her governess, "and here it is: 'Distinguished by its yellowish bark, of a soft silken texture and silvery or pearly lustre,' It is a large tree, and has been named excelsa--'lofty'--because of its height. The slender, flowing branches are very graceful, and the tree is often as symmetrical as a fine elm, but droops less. The roots of the yellow birch seem to enjoy getting above the ground and twisting themselves in a very fantastic manner, and, taken altogether, it is a strikingly handsome and ornamental tree. The wood was at one time much liked for fuel, and many of the logs were of immense size."

"Now," said Malcolm, gleefully, "the canoe birch has got to come next, because there isn't anything else to come."

"That is an excellent reason," replied Miss Harson, "and the canoe birch it shall be. There is more to be said of it than of any of the others, and it also grows in greater quantities. Thick woods of it are found in Maine and New Hampshire--for it loves a cold climate--and in other Northern portions of the country. The tall trunks of the trees resemble pillars of polished marble supporting a canopy of bright-green foliage. The leaves are something of a heart-shape, and their vivid summer green turns to golden tints in autumn. The bark of the canoe birch is almost snowy white on the outside, and very prettily marked with fine brown stripes two or three inches long, which go around the trunk. This bark is very smooth and soft, and it is easily separated into very thin sheets. For this reason the tree is often called the paper birch, and the smooth, thin layers of bark make very good writing-paper when none other can be had."

"Oh, Miss Harson!" exclaimed Clara; "did you ever see any that was written on?"

"Yes," was the reply; "I once wrote a letter on some myself."

"Did you really?" cried two eager voices. "How could you? Oh, do tell us about it!"

"I was making a visit at a village in Maine," said their governess, "where the beautiful trees are to be seen in all their perfection, and I thought it would be appropriate to write a letter from there on birch bark. So I split my bark very thin and got a respectable sheet of it ready; then I cut another piece, to form an envelope, and gummed it together. I had quite a struggle to write on it decently with a steel pen, because the pen would go through the paper; but I persevered, and finally I accomplished my letter. It seemed odd to put a postage-stamp on birch bark, and I smiled to think how surprised the home-people would be to get such a letter. They were surprised, and they told me afterward that the postman laughed when he delivered it."
