SPECIAL NOTICE. BIRD-LORE'S Bird Chart will be sent to all subscribers renewing their subscriptions, and its receipt should be considered a notice that due entry of renewal has been made. Subscribers whose subscription does not expire with this issue may have the Chart at once by renewing now, when their subscriptions will be extended one year from the date of its expiration.

NOTICES TO SUBSCRIBERS

BIRD-LORE is published on the first of every other month by the Macmillan Co., at Crescent and Mulberry streets, Harrisburg, Pa., where all notices of change of address, etc., should be sent.

Subscribers whose subscription expires with the present issue will find a properly dated renewal blank in their magazine. In the event of a desire not to renew, the publishers would greatly appreciate a postal to that effect.

To subscribers whose subscription expired with the issue for February, 1903, and who haveas yet neither renewed their subscription nor, in response to our request, sent us a notice to discontinue their magazine, the present number is sent in the belief that the matter of renewal has been overlooked. We trust it will now receive prompt attention.

Complete sets of Volumes I, II, III and IV of 'Bird-Lore' can still be supplied.

Volume I contains 206 pages, with 79 illustrations; Volume II, 204 pages, with 80 illustrations; Volume III, 228 pages, with 92 illustrations, or a total of 638 pages (equivalent to about 1,200 pages of the average 12mo book), and 251 illustrations.

Every number of Bird-Lore' is as readable and valuable today as when it was issued, and no bird lover who is not already supplied can find a better investment than back volumes of this magazine. Vols. I, III and IV are offered at the subscription price of $1 each, postpaid; the price of Vol. II is $3.

Entered as second-class mail matter in the Post Office at Harrisburg, Pa.
