in each direction. The nests were all of the same pattern, great 
cumbersome piles of sticks, about a foot thick, with but a very shallow 
cavity and no lining.”’ 
The heronry on Riding mountain, Man., is thus described by Mr. 
E. Thompson Seton :— 
“We had struck a heronry; hundreds of these birds were passing 
to and fro, and, on going forward a hundred yards or so, we found 
the tops of the poplars covered with their nests, the young birds, 
full grown but not able to fly, perched on the highest trees. The 
nests were made of the small dead branches of the poplar and were 
placed as near the tops of the trees as possible. These mountains 
are full of small ponds and deep marshes which swarm with 
lizards and small fish, on which the herons feed. On getting to an 
open space near the heronry we could see the old birds coming and 
going in every direction. Those coming home were stuffed to 
the bill with food for their young, making them present a very 
ungainly figure, as they lazily flapped their way towards the 
woods.” 
In May, 1898, a small heronry was found in a birch grove near 
one of the Gaspereaux lakes in Nova Scotia. The nests, to the number 
of five within the space of one acre, were inaccessible owing to the 
great size and nature of the trees selected for the nests. (H. F. 
Tufts.) 
2“ lew years ago this species bred in the township of Escott, Ont., 
and some of the old nests were still left in 1895. In the next town- 
ship—Yonge—a few birds still breed near MacIntosh Mills, and 
their nests may be noticed on some tall pine trees. A large heronry 
existed in a bush near the River Tay, Lanark county, in 1885. 
The nests were built mostly on ash trees, three or four nests often 
in one tree. It still breeds in the township of Elizabethtown, where 
there is a large heronry near Graham lake. Two sets of eggs, five 
of each, were taken from this heronry on May 6th, 1899. (Rev. C. J. 
Young.) In The Ottawa Naturalist, Vol. XVIII, p. 119, Rev. G. 
Eifrig gives a very full description of a heronry near Eganville, 
Renfrew county, Ont. There were between 50 and roo nests all 
in swamp elms, 30 to 50 feet from the ground. 
In Muskoka, Ont., they build in tall pine trees. One tree on 
an island in a lake about twelve miles from Bracebridge had between
