Excerpt from The Economic Value of Our Native Birds: Discussed by Orders and Families; Order XIII, Macrochires, Goatsuckers, Swifts, Humming-Birds, Etc.; Family 20, Caprimulgidae Nighthawks, Whippoorwills, Etc.; Family 21, Micropodidae, the Swifts; Family 22, Trochilidae; The Humming-Birds The work of this office has been so pressing, and growing to such an extent, that it has not been possible to issue the Quarterly Bulle tins as promptly as we have desired, but with a greatly increased force we hope to be able to overcome this difficulty by the next issue. As the value of our investigations depends to a great extent upon the co-operation given by the citizens in various parts of the State, we request all persons who can do so to send us specimens of insects and reptiles for our studies of these creatures in Pennsylvania, and also specimens of such birds, or at least the bird-stomachs with their contents, as they may be able to procure by legal means. Birds are often found dead, and we shall be glad to receive these to make a study of the causes of their death, as well as their food and such other features as will be of value to scientists and other persons. Large specimens may be sent by express, at our expense, and small specimens may be sent by mail, and postage will be re funded. In all cases it is very important that specimens should be so packed in firm boxes or cans that they will not be crushed in transit. As we have no way of keeping specimens alive, and as we especially wish to study their stomach contents, it is quite desirable that they should be killed as soon as they are collected or before shipping. We do not have funds for purchasing specimens at the present time, but shall reciprocate all favors whenever possible. Address all packages and communications to Prof. H. A. Surface, Economic Zoologist, Harrisburg, Pa. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
