Birds of Chester Co., Pa. 



In Mr. Ressel's Birds of Chester Co., Pa., I 

 will omit criticising transient visitants. But 

 regarding his Suinmer re.'iide)if.s I will say that 

 after twenty years of field collecting in this 

 county I have received as yet no ntttlientic 

 proof of any of tlie following aitec'ies breed! nr/ 

 here : 



Bute.o Uneatnx (Ked-shouldered Hawk), Eni-

Remarkable Runt 

 Bluebird. 



A set of six eggs of the common Bluebird 

 (Sialia sldliK) collected on May 18, 188J». in 

 Montgomery County. Pennsylvania, contains 

 one of the most remarkable runt eggs that I 

 have ever seen. Five of the eggs in the set 

 are of the normal size, but the other only 

 measures .44x.88. When it is remembered 

 that the average size of the eggs of this bird is 

 .84 X. 62, it will be seen how very small the 

 runt is. The shell is considerably thicker 

 than that of the other hve, and it contained no 

 yolk. All six of them are of the normal color, 

 and were perfectly fresh. ./. P. .V.

Brief Notes. 



Egg of the 



The O. & O. is mailetl each issiie to every paid suli- 

 scril)er. If vou fail to receive it. notify us. 



By the time that this number reaches our 

 readers the December issue will be well under- 

 way. It will contain the index for the volume. 

 If those of our readers who intend to subscribe 

 for Vol. XV. will notify iis at once it will be of 

 great assistance to us. 



As the close of the present volume draws near we 

 glance over the words of encouragement, hints and 

 suggestions that have l)een received from time to time 

 from our reailers, and shall try and profit by them. 

 Perhajts a general outline of the material on which we 

 build will open new itleas in the future. 



A writes -'The (). & (). is a capital publication, and 

 should be in every household" ; if he did not already 

 take another which is more than he has time to read he 

 would subscribe. 



B. ''I am an interested reader of the O. & O. through 

 the courtesy of my friend who loans it to me. I wish it 

 linancial success." 



C. "Sample copy received. Just what I have wanted 

 for a long time. I enter college next week for a seven 

 years' course. When I graduate, if you still continue 

 publishing, I will subscribe." 



U thinks that he discovers a lawless spirit which he 

 strongly denounces on a postal card, wants it discon- 

 tinued, and adds that the ornithological interest in his 

 school is dying out. [We extend our sympathy and 

 think we discover in him the ability to preach its 

 funeral sermon.] 



E is the .Secretary of a Young Men's Cliristian Asso- 

 ciation. They have six hundred and twenty members 

 belonging to the most substantial families of the town. 

 Unfortunately they are out of funds, and thinks it will 

 l)e of imuiense advantage to us to donate the O. & O. 

 •'Our feelings are touched and we donate." 



F tliinks that we should avoid expressing any opin- 

 ion, as doing so will surely produce antagonism and 

 not only cut down our subscription list but hurt the 

 personal business of the editors. 



(i fully endorses the stand we take and says that it is 

 high time some one awoke to the interests of natural- 

 ists. He sends two new subseribers. 



H writes that he is tired of seeing the lists of birds 

 found in certain counties ; never reads them and con- 

 siders them of no earthly use. 



I .sends for all back volumes that contain local lists ; 

 wants all sucli as can be obtained. 



J discovers an error in a scientiflc name, and thinks 

 it a serious damage to the science of ornithology. 

 [Prospects of a suit !] 



K discontinues because his article did not appear 

 the week it was received. [It was not signed and we 

 were never able to translate the first paragraph.] 



L thinks that he should have fifty extra copies and 

 two hundred separates of his article gratis. [If this 

 was done in each case it would double our expense of 

 publication.] 



M, who lives so far west that the sun does not reach 

 him till the afternoon of the fourth day wouUl subscribe 

 if we could furnish him a copy on the day of publica- 

 tion. 



N failed to receive his last number. If another gets 

 lost in the mail he will not renew next year. 



O refused to renew because the magazine was 

 stopped when his subscription expired, while 



P, who lives three thousand miles from him diag- 

 onally south-east, fairly scorched us for running over, 

 considered it a trick. 



Q finds thei>rint too fine, cover not a congenial color; 

 thinks one of the brief notes was aimed at him, and has 

 discovered that a man that he had a dispute with is a 

 subscriber. He withdraws. 



R called at our i)lace and asked if the O. & O. 

 was "anv good now." He was not satisfied with our
