HOW TO SKELETONIZE LEAVES.
Among the many desirable subjects for photographic printing, none are more satisfactory or so delicate as a graceful arrangement of skeletonized leaves. It may be very simple, and composed of only three or four leaflets; or it may be so elaborate as to embrace specimens from trees and weeds, wild flowers and garden shrubs; while the beautiful seed-pods and grasses, readily found in our fields or along our brooklets, answer for the blossoms in this dainty, fairy-like bouquet.
The methods employed in freeing leaves from their pulpy element, or cellular tissue, as it is more properly called, are very unlike, as practiced by different individuals; but the following, given the author by a lady friend who has a large and extremely beautiful collection of remarkably fine specimens, is very simple, and can be practiced with success by a boy or girl of ten.
Take a wash-bowl, and fill it half full of soft water, into which a heaping teaspoonful of baking soda should be thrown; place this in a sunny window, or one with a southern exposure if possible, and put in your leaves; care must be taken that they are all under water, and not too crowded, although three or four dozen can safely be done at a time. Any leaf which has a firm, well-defined frame-work will make a good specimen. The leaves of the horse-chestnut, maple, silver-leaf catalpa, and magnolia; those of the currant, pear, English ivy, and plum, all make fine skeletons, and many delicate seed-covers, like those of the strawberry-tomato, are very easily treated. Do not confine yourself to this list, however, but try any which resemble these in texture, as a great variety is particularly desirable, if you would have a good collection.
After you have put your leaves to soak in the soda-water, leave them in the sun for three weeks, as that is the shortest time in which any will do. Then look them carefully over, and should any be found nearly free from their tissues, take them out, and wash them off in a bowl of clean water; then with a soft brush liberate any tiny particle that may still adhere to the frame-work, as any blemish of this kind is considered a defect in the specimen.
During this process, be careful to retain the fine threadlike bit of fiber that entirely encircles the leaf and forms an outside frame-work or edge. If it is found impossible to entirely clean the skeleton by aid of the brush, it should be put in a bowl or saucer of clean water and left in the sun for two or three days longer. When they are thoroughly cleaned, place them between the leaves of an old book, and lay them aside until the time for bleaching.
If you live in or near the latitude of New York, the best time to collect and treat your leaves is in June, while they are still fresh and tender, and before the insects have destroyed their shape; but should your home be further south, April or May would be a better time.
After your collection is complete, and all are dry, they will be much improved by bleaching. This process is also very simple, consisting, as it does, of merely dipping them in a weak solution of chloride of lime, and letting them remain there until the proper color is attained; then by slipping a piece of unglazed paper—ribbon paper is best for this purpose—beneath the surface of the water, and bringing it up with the leaf lying flat upon it, the skeleton can easily be taken from the water.
If the form is not inclined to spread out on the paper as it should, take a long slender darning-needle, and with the point carefully arrange it to your satisfaction. Another drying is now necessary, but the bleached leaves should be left on the ribbon paper, which may be put between the leaves of a book as before.
These can be kept for years, and should you be successful and obtain a number of perfect specimens, they will form a very valuable addition to your materials for Christmas gifts, and, prettily arranged, a very acceptable present to any dear friend.
