At the Montreal Forestry Congress, Mr. Caldwell, of Cincinnati, said:

"The monarch of our forests is the sycamore tree. It is a rapid grower and not destroyed by insects. I am indebted to 'Zadok Cramer's Navigator,' published in 1808 at Gittsburg, Ga., for facts which would be incredible if I had not seen the enormous sycamores, which, however, I did not measure. I have seen a section of a hollow sycamore tree used as a smoke house to smoke meat; another as a bin to hold grain; another as an ash-hopper to catch ashes; another as a well-curb. This tree grows near the water courses and does not thrive so well elsewhere. The 'Navigator' named above says : ' It is known to have measured sixteen feet in diameter, four feet from the ground, and this only a common size. One has been known to be sixty feet in circumference. In the hollow of another a man turned himself around with a ten foot pole, at right angles to his body, sweeping inside the tree. On the farm of Mr. Abram Miller, in Scioto county, Ohio, is a hollow sycamore tree, into which thirteen men rode on horseback on the 6th of June, 1808; there was room for two more; the fourteenth was present, but his horse would not enter the strange apartment.' I say, further, this tree is valuable for housebuilding and for cabinet work, but it is not the most valuable."
