The young hawk yet in the nest is called an eyas, one that can hop is a brancher, and a young hawk able to catch game is called a soar hawk. Young hawks taken in flying are called passage hawks, and the training of these is called reclaiming. Hawking was for many years a sport followed by kings and the nobility in Europe. It is of very ancient origin, having been followed in Asia and Europe before the time of the Christian era. The hawk builds its nest in the forks of a tree or on some inaccessible cliff. The female is larger than the male and lays two or three eggs. CURIOUS TREES. 1. In Malabar, a tree called "the tallow tree" grows; from the seeds of it, when boiled, is procured a firm tallow which makes excellent candles. 2. The "butter tree" was discovered by Park in the central part of Africa; from its kernel is produced a nice butter which will keep a year. 3. The _palo de vaca_, or "cow tree," grows on rocks in Venezuela, South America. It has dry and leathery leaves, and from incisions made in its trunk a kind of milk oozes out, which is tolerably thick and of an agreeable balmy smell. At sunrise, the natives may be seen hastening from all quarters furnished with large bowls to receive the milk. 4. A tree of Madagascar, called the "traveler's tree," yields a copious supply of fresh water from its leaves, very grateful to the traveler. It grows in the most arid countries, and is another proof of the tender care of our Heavenly Father in supplying all His creatures' wants. Even in the driest weather a quart of water can be obtained by piercing a hole at the bottom of the leaf stalk, and the liquid is pure and pleasant to the taste. The leaves are of enormous size, varying from ten to fifteen feet in length. 5. The date tree is a species of palm, and almost every part of it is valuable. Its fruit is delicious and it is also esteemed for the palm wine drawn from its trunk. Its leaves are made into hats, baskets, fans, and many other articles, and the fibres of the leaf stems are made into cord and twine. A department store might almost be furnished from this tree. 6. The "sorrowful tree" is found on the island of Goa, near Bombay. It is so called because it flourishes in the night. At sunset no flowers are to be seen, but soon after it is covered with them. They close up or drop off as the sun rises. It has a fragrant odor, and blossoms at night the year round. 7. There is a tree in Jamaica called the "life tree," whose leaves grow even when severed from the plant. It is impossible to kill it save by fire.--_Normal Instructor._ [Illustration: BLACK-THROATED BLUE WARBLER. Life-size FROM COL. F. M.
