This issue of the Bulletin was mailed Jan, EDITORIAL NOTES. The index to Volume I, mailed with this is- sue, is the work of Mr. Richard C. McGregor, to whom the editors return thanks for this and other valuable assistance rendered during the year. Mr. Swarth's list which records I75 species and subspecies of birds within the confines of a Ioo-acre ranch in the city of Los Angeles, is an illustration of the extended list and interest- ing facts which systematic and caret?l obser- vation will accomplish, and we venture to say that few observers in the Club can show as complete a list for a like area. Volume I of the BULI?ETIN can be supplied while the back numbers are in print, at ?;z. per volume. The I?o pages of text em- braced in the volume, contain new bird de- scriptions, valuable observations on the nests and eggs of numerous little-known species, besides a mass of popular material and biog- raphies, which make the volume especially desirable for future reference. The Club library has recently added Tarher's "Contributions to the Natural History of Alaska" and Nelson's "Report upon Natural History Collections Made in Alaska," with the excellence of which volumes, ornithologists generally, are acquainted. Both volumes are donated by Mr. Lyreart Belding of Stockton, who has on previous occasions shown his generosity and good-will toward the Cooper Club. ERRATUM:--In our last issue in reviewing the collection of Miss Jean Bell, reference was made to the purchase of "over one thousand selected sets from the collection of Mr. Thos. H. Jackson." This statement was a regret- table error, as Mr. Jackson has never offered for sale his collection nor any part of it. The sets mentioned were from the collection of Mr. S. B. Ladd. We regret the injustice done Mr. Jackson and take pleasure in making this correction. As an illustration of the knowledge accrning froin proper collecting in the field, we might call attention to the communication of Mr. Jos. Mailliard in this issue on the color changes in the crown of certain of the Picidg, a point which it appears has heretofore been over- looked. This demonstrates the necessity of collecting in series at proper seasons, and it would seem that all unbiased ornithologists must concede that the results amply justify such collecting. In preparing the completed volumes of vari- ous ornithological journals for binding, one cannot but notice a grievous fault in the mat- ter of allowing advertising pages to become so mixed with the text that they cannot be eliln- inated in binding. This is, at best, unsightly, and after removing the covers and superfluous advertising pages, we too often find the back of the last sheet devoted to advertising which cannot be done away with because the reverse side is given to text. We notice this fault even in that model of typographical propriety,- tird-Lore. Ifadvertisingpages must be in- serted, they should be so printed that the half- . sheet containing them can be torn off, leaving the corresponding pages of text to be bound, thus causing no interruption of the consecu- tivehess of the pages in the bound volume. Is 'it not well for our publishers to keep this mat- ter, t?fling as it may appear, in mind? Amid many graceful compliments, the CON- DOR, with earnest stroke, launches itself upon its second volume, feeling that its range has been wisely proven sufficient for its support. The magazine will be but the BULLETIN of ?899 uuder its new and briefer and more dis- tinct title, and it expects to ?ain support wholly through its course of presenting the most attractive and valuable articles on oruith- ology to the fraternity. Every publisher must have discovered that it is next to impossible to thrust upon the public something it does not want, and the CONDOR has therefore relied solely upon its merit for support, and this, we may modestly add, has not been slow in forth- coming. A second volume of promptly issued numbers, filled with articles of merit and in- terest, is therefore assured. The new cover adoming this issue is the work of Mr. W. Otto Emerson, the Cooper Club artist, whose talent has frequently been displayed. for the Club's benefit. Subscribers are requested to remit their re- newals direct to the CONDOR, as no discount is allowed agents for renewals and this course, therefore, becomes the most direct one.
