and disappeared within the cavity. This tree is well shown in 
Dawson's “Birds of Ohio” Pp. 3738. The set taken by Dr. 
Jones was taken on May 27th, 1897, and fully one-half of the 
specimens of this species that have been brought to my no- 
tice have been taken in this immediate vicinity. It would 
seem as though most of the birds had been raised in one or 
the other of the two cavities. I have never heard of this bird 
showing a special attachment for a certain locality, but this 
case extending over a period of thirteen years, would seem 
to indicate, in this case at least, that such is the case. No- 
vember 14th, 1910; a female that was shot from a barn three 
miles east of Circleville, along Hargus Creek, was brought 
to me by a farmer who was “afraid it would take his chick- 
ens,’ unaware that he had killed a mouser that was worth 
a halt dozen cats.

Marsh Hawk (Circus hudsonius)—On May 19th, 1910, 1 
had the good fortune to discover the fourth authentic set of 
this species ever taken in Ohio, (according to Dawson's 
“Birds of Ohio.”) I was approaching a boggy meadow over- 
grown with marsh grasses in search of rail nests, when I 
saw a hawk perched upon a fence post in the distance, and 
remarked to my companion that the bird looked like a Marsh 
Hawk, but soon dismissed the thought from my mind as im- 
probable. Proceeding well into the centre of the swamp, I 
flushed the female from her four mud stained eggs. The 
nest was built upon the ground, surrounded by a number of 
short, stunted wild rose bushes, where there was a slight el- 
evation above the surrounding marsh, and the ground was 
therefore dry. The nest was composed mainly of “tassels” 
from the tops of corn stalks; several weed stalks entered 
into the composition of the nest, among which was a stalk 
of teasle and a large smart weed stalk. <A tuft of corn silk 
lay at the edge of the nest. The female hovered about for a 
few moments, hut soon joined the male, who had remained 
at a distance, when both flew away. The eggs were fresh.
