202 Bird -Lore your subscription when it expires, or in the event of your not caring to re-sub- scribe, we ask, as a means of regulating our edition, that you kindly send us a postal to that effect. Bird-Lore for 1900 Bird-Lore for igoo will, we think, reach a standard of excellence not before attained by a journal of popular orni- thology. No effort has been spared to secure authoritative articles of interest to the general reader, as well as those of practical value to the teacher and stu- dent. There will be papers by John Bur- roughs, recording the rarer birds he has observed about his home ; by Bradford Torrey, describing his methods of at- tracting winter birds ; by Robert Ridg- way, on song birds in Europe and America ; by Otto Widmann, on a visit to Audubon's birthplace ; and also con- tributions from William Brewster, E. A. Mearns, C. Hart Merriam, T. S. Roberts, and other well-known ornithologists. A VALUABLE Contribution to the study of bird migration will be a paper by Captain Reynaud, in charge of the Homing Pigeon Service of the French Army, who will write of his experiments in this branch of the service. Attention will be paid to the bird-life of countries made prominent by recent events : L. M. McCormick, who has lately returned from the Philippines, writing of the birds of Luzon; H. W. Henshaw, of the birds of Hawaii, where he has long been a resident ; Tappan Adney, who passed a year in the Klon- dike, of the birds of that region ; and F. M. Chapman, of the birds of Cuba. A. J. Campbell, the authority on Aus- tralian birds, will also contribute a paper on foreign birds, describing the remarka- ble habits of the Bovver Birds, with pho- tographs of their bowers from nature. For teachers there will be a series of suggestive articles on methods of teach- ing ornithology, by Olive Thorne Miller ; Florence A. Merriam ; Marion C. Hub- bard, of Wellesley ; Lynds Jones, of Ober- lin, and others, who have made a spe- cialty of instruction in this branch of nature study. Students will be glad to avail them- selves of the assistance offered by Bird- Lore's Advisory Council, a new idea in self-educational work, the details of which are announced on another page. Among papers designed more especially for students will be Ernest Seton-Thomp- son's ' How to Know the Hawks and Owls,' illustrated by the author, F. A. Lucas' ' Tongues of Birds,' also illustrated by the author, and Professor Pinchot's 'A Method of Recording Observations. ' A PAPER of unusual value to those who study birds with the aid of a camera will be by John Rowley, of the Ameri- can Museum of Natural History, who will describe a recently invented camera which opens new fields in bird pho- tography. For ' Young Observers ' there will be articles by other young observers, and poems and jingles all designed to arouse and stimulate the child's interest in birds. The illustrations will, if possible, be of even higher quality than those for which already Bird-Lore has become distin- guished. The Audubon Department, under Mrs. Wright's care, will, as heretofore, print reports of the great work which is being done in the interests of bird study and bird protection, and the series of helpful articles by its Editor will be continued. This outline of the leading features of Bird-Lore for the coming year will, we trust, be deemed sufficient warrant for the belief expressed in our opening sentence. It will be seen that our diffi- culty is not lack of material, but lack of space, and this difficulty we hope our subscribers will help us to overcome by seconding our efiorts in their behalf.
