Pliny, the first great naturalist, said he thought honey-dew was "the perspiration of the sky, the saliva of the stars, or the moisture deposited by the atmosphere while purging itself, corrupted by its admixture with the mists of the earth." Bees gather it and make it up into honey. Squirrels are fond of it, and gather the leaves one at a time, hold them up in their paws, and lick them with apparent relish. There are so many truly wonderful things about bees which this talented writer has collected and told in simple language that her book is one of the most valuable of recent contributions to the libraries of those who enjoy the wonders of nature. Although written evidently for children it is of absorbing interest to adults, and furnishes a fund of material for conversation and observation which will make it very much in demand among teachers and parents. The growth of the bee, the drones, the workers, and the queens, with all the details of their structure as revealed by the microscope, the making of their curious homes, their odd customs and habits, their strange enemies, and a thousand other interesting features, make the subject one of great interest, and we cannot sufficiently honor the memory of the blind naturalist, Huber, who found out more things about bees after he lost his sight than all the world ever knew of them before his time. BAD GERMS.--In our bodies is constantly going on a great fight between germs of various sorts, if we are to believe those who know most on the subject. Microbes are all about within us, some of them apparently striving to do us good and others trying to kill us. In a few cases men of science have been able to find one kind of germ that will destroy another that is hurtful to the human system. By cultivating many sorts of germs together and separately they have come to know a great deal about what microbes like and what they cannot bear. The so-called poisons of diphtheria and typhoid fever have been recognized as having certain forms and characteristics, and a way of killing them off at wholesale has been found, and so we are not so much afraid of these diseases as we were before these discoveries were made. The germs of cholera and yellow fever are now well enough known to be controlled by sanitary measures, and the doctors are hot on the track of the bacillus of consumption. What relief the world will have when these germs are killed before they have had time to do their deadly work!
