In the accompanying sketch the measurements between the trees were roughly paced off, the trees not occupied by nests being omitted. Also, the size of the trees is only approximate, as no tape line nor rule was available for more ac- curate measurements. The shape of the whole group is roughly a parallelogram with the long sides extending some one hundred seventy-five feet north and south, while it is about one hundred feet wide. From the southeast corner of this ex- tends a row of four trees, the farthest one being one hundred ten feet from the corner. All of these trees are hard maple except two, and vary in size from eight to thirty-six inches, the majority of them being twenty or more inches in diameter. The two ex- ceptions are elms, one (8) being located in the northwest corner, and the other (4) being the fourth from the south end of the de- tached line. Near the last-men- tioned tree is the fallen trunk of another elm of good size which has been dead for some time and which blew over last spring. Probably it held nests of the Heron at some past date, but not last year, as no remnants of nests were in or near its fallen branches. The hard maple (5) located at the southeast corner of the parallelo- gram has two trunks of about the same size, twenty inches. The total number of nests in the trees and on the ground under them numbered sixty-six. Eight of this number were on the ground, but were in good condition, and had evidently been used.
