REBECCA D.--There are several works on the Egyptian Pyramids, but all of them are too scientific and learned to be interesting to young readers. If you live near a library which contains encyclopædias, you will find in them all that you would care to read at present about their age and probable origin and purpose. The largest and most interesting are at Jeezeh, about twelve miles from Cairo, and seven from the banks of the Nile. Learned men differ in regard to the time when they were built, as well as for what use they were intended. Some calculations place the date at about 2170 years B.C., and while some scholars hold that these enormous structures were intended for royal sepulchres only, others suppose that they were built for astrological purposes. Although erected in the childhood of the human race, the masonry of the Pyramids is far superior to that of modern times. The joints of the casing-stones, that still partially cover the sides, are so close that the thinnest paper can not be inserted in them. * * * * * B. T. H.--As allegory is a figurative representation in which a story or a picture signifies something more than its literal meaning, it is the privilege of an artist to call his ideal picture "Temperance," "Fortitude," or anything else he pleases. Probably the pictures you saw were given those names because to the artist's mind they represented the characteristics of those particular virtues. * * * * * A very large number of our little correspondents have sent us poems on spring and the fresh grass and flowers. We can not print any of them, but we thank them for their favors. Their fancies are all pretty, and we are glad to see that boys and girls are such close observers of Nature, and that they love her changing moods well enough to write her praises in verse. * * * * * The editor thanks Tillie S. for her pretty Easter-egg, with its kind wishes. * * * * * G. S. H.--Long Island is a part of New York State, and is included within its boundaries. It may properly be said to be in New York State. * * * * *
