A cuckoo pleading for her nest of young would soften a heart of stone. With wings and tail spread, she flutters almost into one's face, uttering pathetic and heartrending cries that beseech you not to touch her treasures. In pinfeathers the young of this bird, as well as those of the chimney swift, resemble baby European hedgehogs. July Twenty-sixth Trees and flowers must sleep as well as animals. The dandelion closes its petals late in the afternoon, and as night approaches the water lily folds up tightly. Although summer in the North is shorter than the summer in the South, the days are several hours longer, so vegetation is growing here while their trees and flowers are sleeping. This provision of Nature gives the northern Indian vegetables and flowers in a country which we often call "a land of snow and ice." July Twenty-seventh The common milkweed is another one of Nature's fly traps. Examine some of the fragrant flower heads and you are almost sure to find a captive held firmly by the foot. "The silky hairs of the seed-pods have been used for stuffing pillows and mattresses, and can be mixed with flax or wool and woven to advantage." (Dana.) [Illustration: YELLOW-BILLED CUCKOO.] Notes July Twenty-eighth One of the simplest duties of a spider's life, is the stretching of a parallel web. Tiring of her location, the spider begins to spin a thread, or tangle a mass of threads together, until they are of sufficient buoyancy to support her weight. Then she fastens one end of a strand to the point she is about to leave, and clinging to the under side of her improvised balloon, floats away with the breeze. She pays out silk until the thread parts, or she finally comes in contact with some object, and so the cable is laid. July Twenty-ninth Young song sparrows, chipping sparrows, field sparrows, cedar-birds, bluebirds, and robins are streaked and mottled on the breast during the first few months of their lives. Another noticeable fact is that young birds fluff their feathers, and as the old birds are often thin from care and worry, the youngsters seem larger than their parents. July Thirtieth The dobson, or "hellgrammite," is honored with about sixteen other names. Its chalky-white mass of eggs about the size of a dime are now common objects along inland waterways. As soon as the eggs hatch, the young dobsons drop into the water and hide beneath stones for three years, feeding on aquatic larvæ of insects. Notes July Thirty-first The river crab, or crawfish, has five pairs of walking legs and six pairs of swimming legs. If a leg is lost, another will grow within a year. The female lays a large number of eggs, which are attached to the fringes of her body. These crabs have two pairs of antenna-like organs, one to feel with and the other for hearing. The compound eyes are set on two pegs that can be protruded or depressed at will. Notes =August= August First
