[7] Since writing the above, the following account has come to hand: "The Bald Cypress of Oaxana (_Taxodium distichum_) and the famous Chestnut of Ætna have been often cited as the giants of the vegetable kingdom. But these sovereigns are dethroned, and put into the second rank by those lately discovered in Tasmania, which leave far behind them those antique monuments of nature. Last week I went to see the two largest trees existing in the world. Both of them are on the border of a small stream tributary to the river of Northwest Bay, in the rear of Mount Wellington. They are of the species named there Swamp Gum; I and my companions (five of us) measured them. One of them had fallen; we therefore easily obtained its dimensions. We found its body two hundred and twenty feet from the ground to the first branch. The top had broken off and partly decayed, but we ascertained the entire height of the tree to have been certainly three hundred feet. We found the diameter of the base of it to be thirty feet, and at the first branch twelve feet. Its weight we estimated to be four hundred and forty tons. The other tree, now growing without the least sign of decay, resembles an immense tower rising among the humble Sassafras-trees, although very large in fact. The Gum-tree at three feet above the ground measured one hundred and two feet in circumference. In the space of a square mile, I think there were not less than one hundred of these trees, none less than forty feet in circumference. It must require several thousand years to produce the largest one."--_Revue Horticole._ In Doctor Dwight's Travels we have an account of a tree in Lancaster, New Hampshire, which measured two hundred and sixty-four feet in length. "Fifty years ago, several trees growing on rather dry land in Blandford, measured, after they were felled, more than thirteen rods and a half, or two hundred and twenty-three feet in length."
