brown; feet and cere yellow. On the 2nd of July I took the re- 
maining egg, feeling convinced that it had got a chill; and my friend 
Hargitt, to whom I gave it, writes to me that this proved to be the 
case, the embryo being far advanced, but not commensurately with 
the length of incubation. I had to go abroad on the 3rd, and it is 
to the kindness of my friends Capt. Hadfield and Mr. Hargitt that 
I am indebted for the following notes on the gradual growth of the 
young harrier. By the 5th the quill-feathers had sprouted con- 
siderably, and he was thirteen inches from tip to tip; remains of 
several small birds—amongst them, skylark, titlark, stonechat and 
yellowhammer—were round the nest; and he seemed to have as 
much as he could eat. By the 10th the quill-feathers were about 
four inches and the tail-feathers one inch and a half in length, 
blackish brown with a rich rufous border, the patch on ear-coverts 
being nearly the same colour. By the 13th the breast and flanks 
were covered with chestnut feathers, the scapulars well advanced, 
and the feathers increasing rapidly on the nape and head, although 
there was still a considerable amount of down on the latter. At 
this stage my friends thought it advisable to fasten the young bird 
by the foot to prevent its escape; but on the 16th Capt. Hadfield, 
finding that it had freed itself, decided upon taking it, which he 
did with some little difficulty, as the bird was now active and 
somewhat fierce. 
Capt. Hadfield records that the meat provided for it that night 
remained untouched, but the next day it took small pieces from the 
point of a stick, and gradually became tamer day by day with its 
captor, although always alarmed at strangers. By the 25th of July 
it had acquired the free use of its wings, flying round the lumber 
room in which it had been placed in a buoyant manner, and taking 
great pleasure in its bath, in which it would stand knee-deep, 
enjoying being sprinkled with water, after which it would spread its 
wings and bask in the sun. At intervals it was captured, and 
measurements were taken, the principal result of which is to show 
that the third primary, which when fully grown is the longest by 
about three-fourths of an inch, is the latest in attaining that extent. 
On the 18th of August the wing from flexure measured fourteen 
inches, the first primary being 2'2 inches shorter than the second ; 
but even on the 28th the full growth was barely reached. It may 
be as well to quote the relative lengths of the primaries as taken on 
that date by Capt. Hadfield and myself:—First primary 26 inches
