Measurements.- -Full and reliable data on the measurements of the 
nest are, with a few exceptions, a minus quantity. Few observers think 
it worth while to take notes of this kind, and the wide latitude taken by 
those who have recorded the proportions of the nest, renders it extremely 
difficult to arrive at a safe average. Outside of New York and Pennsyl¬ 
vania, the notes are not sufficiently numerous to give an average of value

The above is deducted from data collected in New York and Pennsylva¬ 
nia, and all measurements are given in inches and hundredths of an inch 
While the inside measurements do not differ materially between early and 
late nests, the external measurements do to some extent. The early 
builder constructs a slightly larger and much more compact nest than 
the bird building late in the season, /. c ., last week in April and first week 
in May. 
EGGS. 
Time Between Completion of Nest and Deposition of First Egg.- 
Little or no light has been thrown on this, Mr. Ellis F. Fladley, Dayton, 
Oregon, asserts that a month intervens, I have found that the female, 
if hard pushed, will deposit her first egg as soon as the nest is completed ; 
at other times, often from four to eight days passed before the first egg 
was laid. 
Deposition of Full Clutch.— Mr. Lynds Jones has found that if the 
female be hard pushed, as is often the case when the nest is long in 
building, the eggs are laid each day until the set is completed, othewise 
often a day intervens, when she is not so pushed. Mr. Victor Dewein, 
Peoria, Ill., has found that in some cases it takes eleven days to lay a full 
complement of five eggs. I would say that ordinarily a full clutch is de¬ 
posited in as many days as there are eggs in the set, in South-eastern 
Pennsylvania. 
Nunber of Eggs in a Set. —It has only been of recent date that the 
“ number of eggs in a set” has received much attention; and many of 
our most eminent ornithologists and oologists have gotten themselves at 
once into deep water, when they set down arbitrary figures without suf-
