Under a large cedar in the middle of lot 2seeds of the following additional fruiting plants were collected: Elder, hackberry, bittersweet, sour gum, smilax, blueberry, flowering dog-wood, and poison ivy. The most striking examples of trees planted by birds at MarshallHall are the ox-heart cherry trees that extend along the river frontfor half a mile. Almost as notable, perhaps, are the tall cedar treeswhich stand in long rows between adjacent fields (see PL XII, fig. 1).Scattered over the old pastures, also, little cedar trees, like fox brushes, attest the work of the winged planters, but in the arable land therotation of crops kills all except such as may start along fence rows.
