ive it the look of an
ash, and the trunk is smoother than that of most large trees. In summer
the finely-cut foliage is of a bright green, and in autumn it changes
to a rich orange, which lasts after the other species have become russet
and brown."

"Is there anything more about hickory trees?" said Clara.

"Only to speak of the great value of the wood," replied Miss Harson.
"Its uses are almost endless. Great numbers of walking-sticks are made
of it, as for this purpose no other native wood equals it in beauty and
strength. It is next in value to white oak for making hoops; it makes
the best screws, the smoothest and most durable handles for chisels,
augurs, gimlets, axes, and many other common tools. As fuel, hickory is
preferred to every other wood, burning freely, making a pleasant,
brilliant fire and throwing out great heat. Charcoal made from it is
heavier than that made from any other wood, but it is not considered
more valuable than that of birch or alder. The ashes of hickories abound
in alkali, and are considered better for the purpose of making soap than
any other of the native woods, being next to those of the apple tree."

"There, Clara!" said Malcolm; "you see now why people cut down hickory
trees. The nuts are nowhere, with all these other things."

"We have finished the walnut family," said Miss Harson, "but there is a
tree that I wish to speak of here because of its long pinnate leaves,
which appear to connect it with the walnuts and hickories. This is the
ailanthus, a large tree which you have often seen in the village, and
which used to be popular as a shade-tree. It is very clean-looking, for
the only insect that will eat its leaves is the silkworm."

"Oh, Miss Harson!" exclaimed the children. "Are there real silkworms on
'em? and can we see 'em?"

"Why, do you not remember our talk about silkworms?" replied their
governess. "I am sure I told you that they would not live here in the
open air, but they do in China; and the ailanthus is a Chinese tree. It
was planted in Great Britain over a hundred years ago for the express
purpose of feeding silkworms, because a species of silkworm which was
known to be hardy and capable of forming its cocoons in the English
climate is attached to this tree and feeds upon its leaves. It was not
successful, however, for silkworms, but as a stately and ornamental tree
with tropical-looking foliage it was much admired. The ailanthus is
quite common in this country
