New Haven is popularly known as the "City of Elms," because of the number of these trees.
Mission Park (10 acres) here is adorned by native and foreign shrubs and by maples, elms, pines and arbor vitae, and "Haystack Monument" in this park marks the place where Samuel John Mills (1783-1818), in 1806, held the prayer meeting which was the forerunner of the American foreign missionary movement.
Such are the cork-warts on elms, maples, &c., and the class of outgrowths known as Intumescences.
Turning now to outgrowths of a woody nature, the well-known burrs or knaurs, so common on elms and other trees are cases in point.
The streets of Portland are generally well paved, are unusually clean, and, in the residence districts, where the fire of 1866 did not extend, they are profusely shaded by elms and other large trees - Portland has been called the "Forest City."
