concluded to take another cope as nearly like the first as could be 

 had, putting it in the same position as the first and moving the 

 nests to the same relative positions and await results. 



This plan was carried out excepting the arangement of the nests; 

 for on July 7, when I again visited the nests, they were placed as 

 shown below — the foundations Nos. 4 and 5 not having been moved. 

 However, when I approached, Mrs. Robin was 

 seen sitting on nest No. 1. On July 8, she 

 was on nest No. 2, but on the 9th, 11th, 12th, 

 13th and 16th she was on No. 1. On July 20 

 two young birds were found and the nest was 

 deserted on the 29th. Nest No. 3 was com- 

 pleted but did not seem to have been used.

Mrs. Robin will no doubt remember her hard trials but eventual 

 triumph over difficulties, a long time and steer clear of the flask 

 yard: but I felt abundantly repaid for the experiment. Another 

 time I should put all the eggs in one nest. — Fraxk Bbuen, Bristol, 

 Conn., December. 1904. 



Moving a Wren's Home. — For the past two seasons a pair of 

 House Wrens have built their nest in a crevice formed at the joint 

 where brace and post meet on the veranda of the Bristol Golf Club 

 Tea House. From May 11 to 27, this year (1904) the building was 

 dismantled and moved to a new site about three-fourths of a mile 

 distant. When the veranda was taken down the wren's nest came 

 out and fell to the ground. The men employed noticed the birds 

 at that time but do not remember whether they were about after- 

 wards or not. 



July IS, a pair of Wrens, presumably the same, were still using 

 the crevice at the new location. 



My chain of evidence I know is weak in the above, and I write 

 this more to draw out the experience of other members of the 

 club than for its scientific value. — Frank Bruen, Bristol, Conn., 

 December, 1904. 



Bird Btjixdeks at Fault. — Apropos to Mr. Bruen's "Transplant- 

 ing a Robin." John Burroughs in Bird Lore, page 85, 1901, under 

 the title of "A Bewildered Phcebe," gives an instance of a builder 

 at fault. The bird confronted by new conditions, blunders, but 

 through its great industry is not altogether baffled by the multiplic- 

 ity of building sites. I have frequently observed the same trouble 

 when the Robin or Pewee selected a place midway on a beam or 

 plate partitioned by rafters into short stretches exactly alike, par- 

 ticularly where there was no resting perch in full view of the nest- 

 ing site. Naturally, when a corner of the building is chosen in 

 the beginning, there is no difficulty, for it may be easily distin- 

 guished. Less commonly the Bluebird, House Wren and Purple 

 Martin err when building in a many-roomed box, also doubtless
