DECIDUOUS TREES. 
Such trees as this purple oak, the Moccas oak, and the weeping 
Turkey oak, can readily be grafted on our white oaks, so that per- 
sons having young and thrifty trees may, with care and persistency 
through a term of years, secure samples of these curious oaks, and 
produce novel effects of foliage and form on the same tree. The 
work must, however, be done year by year, so as not to give the 
stock a maimed expression, or injure its health. 
The Holly Oaks. Quercus virens . — These are mostly ever- 
greens, natives of Southern Europe and Asia, near the sea. They 
will not bear our winters, though they can with care be grown in 
some parts of England. 
THE ELM. Ulmus. 
The Elm family embraces many species, mostly large trees. 
Our indigenous weeping elm, Ulmus afnericana, is, however, so much 
better known in this country than any other, and has so long borne, 
and deserved, the crown and title of “queen of American trees,” 
that it is always the species uppermost in the mind when Americans 
speak of the elm. Yet in England and Continental Europe the 
Dutch, English, and Scotch elms have not been supplanted by it. 
The American Weeping or White Elm. Ub?ius mtiericana . — 
A full grown luxuriant weeping elm is certainly the queen, as the 
oak is the king, among deciduous trees. Its grace is feminine. Its 
outstretching arms droop with motherly grace to shelter and caress 
with their mantle of verdure the human broods that nestle under 
them. It is also a grand tree, well characterized by Dr. Holmes as 
“A forest waving on a single stem.” 
Few trees are more lofty in their native woods, and none spread 
with more luxuriant amplitude in rich alluvial fields. The roots 
around the base of the trunk rise from the ground with peculiar 
picturesqueness to brace it against the winds. Its long branches, 
curving symmetrically upwards and outwards, describe the segment
