It is stated that a thousand species of ants are known. No doubt there is much of interest about each kind. The "Driver Ant" is so choice of time and labor that, when building its covered roads, if a crevice in a rock or a shady walk is reached, it utilizes these, then continues arching its path as before. If a flood comes these ants form into large balls with the weak ones in the middle, the stronger on the outside, and so swim on the water. The ant benefits man by acting as a scavenger, by turning up the subsoil, and in various other ways. But flowers prefer the visits of moths and butterflies; as ants are of no service to them in scattering pollen, they do not wish them to get their honey. Some of the flowers have found out that ants, though so industrious by reputation, are lazy about getting out early in the morning for they dislike the dew very much. Hence by 9 o'clock these wary flowers have closed their doors. Others take the precaution to baffle ant visitors by holding an extra quantity of dew on the basins of their leaves, while still others exude a sticky fluid from their stems which glues the poor ants to the spot. Campanula secretes her honey in a box with a lid. Cyclamen presents curved surfaces, while narcissus makes her tube top narrow. Other flowers have hooks and hairs by which the ants are warned to seek their honey elsewhere. THE CHARITY OF BREAD CRUMBS. The recent "cold wave," which with its severity and length has sorely tried the patience of Denver's citizens, has had its pleasant features. Perhaps chief of these has been the presence in our midst of scores of feathered visitors driven in, doubtless, by pangs of hunger, from the surrounding country. Flocks of chickadees have flown cheerily about our streets, chirping and pecking industriously, as if to shame those of us who lagged at home because of zero temperature. They were calling to one another as we stood at the window watching them last Saturday morning. Suddenly, down the street with the swiftness and fury of an Apache band, tore a group of small savages, each armed with a weapon in the shape of a stick about two feet long. "What can those boys be playing?" inquired someone, and the answer to the question was found immediately as in horror she saw the sticks fly with deadly exactness into a group of the brave little snowbirds, and several of them drop lifeless or flutter piteously in the frozen street. "How can boys be so heartless!" said the lady, rising in righteous wrath to reason with them. "Thoughtless is nearer the truth," remarked a friend who had witnessed the scene. "Their hearts haven't been awakened on the bird question and it would be better to try and stir up their mothers and teachers than to fuss at the boys themselves." But the Denver birds have plenty of friends and this has been proved many times during the past week.
