From an extensive series of experiments, it has been learned that the male finds his mate by means of scent and that this is doubtless the explanation for the very large antennae of the male, since it is in these organs that the sense of smell is located. Although it may be very interesting to read about the activities of insects, a much more fascinating side of the subject is to handle and study the insects themselves, and there are but few better insects with which to begin a personal acquaintance than these which we have been considering. Charles Christopher Adams. A PLEA FOR LEGISLATIVE PROTECTION. In former numbers of Birds and Nature we have seen how much our welfare and happiness depends upon the birds. Some hints have been given as to how we may encourage the birds to become residents of our premises so that we may enlist them in the constant warfare against worm and weevil. If there were no great and universal interest at stake in this question, How much do we owe to the birds? we should, perhaps, have no right to go beyond simple encouragement to the birds to multiply and do their good work in certain chosen places. But the interests are universal and so deeply concern the whole world that we have an undoubted right to say to those who would kill everything in sight, either for gain or for so-called "sport," Thou shalt not! In other words, we have the right to make laws forbidding anybody to kill birds except for the best of reasons. This right has been acted upon in most states and in many foreign countries, where various degrees of protection to the birds as well as to other animals have been secured. But in very many, if not in most cases, the laws enacted have not furnished protection enough. Those who have put a price upon a bird's plumage, who furnish the temptation for others to break the law against killing birds, have not had a check put upon them. And the class of "sportsmen" which regards anything living (except man and some of the domestic animals) as legitimate targets for their weapons, have not been dealt with severely enough. Even where the laws have seemed prohibitive enough they have often failed of their purpose because not properly enforced. There are, then, two things to be considered. First, the passage of laws that will be prohibitive, and, second, machinery adequate to their enforcement.
