In the Atlantic states, especially at a considerable distance from the sea, tulip trees are often seen seventy, eighty and one hundred feet in height, with a diameter of eighteen inches to three feet. But the western states appear to be the natural soil of this magnificent tree, and here it displays its most powerful vegetation. M. Michaux mentions a tulip tree, near Louisville, on the Ohio, which at five feet from the ground was twenty-two feet six inches in circumference, and whose elevation he judged to be from one hundred and twenty to one hundred and forty feet. The flowers bloom in June or July. They are large, brilliant, and on detached trees very numerous, variegated with different colors: they have an agreeable odor, and produce a fine effect. The fruit is composed of a great number of thin, narrow scales, attached to a common axis, and forming a cone two or three inches in length. Each cone consists of sixty or seventy seeds, of which never more than a third part are productive. For ten years before the tree begins to yield fruit, almost all the seeds are unproductive, and on large trees, those from the highest branches are the best. _Catalpa._――In the Atlantic states, the _Catalpa_ begins to be found in the forests, on the banks of the river Savannah, and west of the Alleghanies, on those of the Cumberland, between the thirty-fifth and thirty-sixth degrees of latitude. Farther south it is more common, and abounds near the borders of all the rivers which empty into the Mississippi, or which water West Florida. In the regions where it grows most abundantly, it frequently exceeds fifty feet in height, with a diameter from eighteen to twenty-four inches. It is easily recognised by its bark, which is of a silver-gray color, and but slightly furrowed, by its ample leaves, and by its wide-spreading summit, disproportioned in size to the diameter of its trunk. It differs from other trees also by the fewness of its branches. The flowers which are collected in large bunches at the extremity of the branches, are white, with violet and yellow spots, and are beautiful and showy.
