produce its slender erect spikes of rose-colored flowers. This is one of 
Wilson’s discoveries in western China and one of the most beautiful 
of the small hardy shrubs of recent introduction. 
The name Ulmus campestris has been selected by recent writers on 
European trees for the Elm of the hedge rows of southern England, 
which was largely planted a century ago in eastern Massachusetts 
chiefly, no doubt, through the agency of a Major Paddock who estab- 
lished a nursery of this tree in Milton. The large English Elms which 
once flourished on Boston Common were of this species, and large 
specimens can still be seen in several of the Boston suburbs. The ori- 
gin of this Elm is unknown. It does not produce seeds propagating 
itself by suckers, and is known to grow spontaneously only in some 
of the counties in southern England, and in a few parks near Madrid, 
in which it is now known to have been introduced from England many 
years ago. It is a noble tree, able to adapt itself to various climatic 
conditions, and well suited to those of New England; indeed no other 
exotic tree, with the exception of the European White Willow, has 
been here so long or grown to such a large size. Another English 
Elm, Ulmus vegeta, usually called the Huntington Elm, a supposed 
natural hybrid between two European species, Ulmus nitens and U. 
glabra , the so-called Scotch Elm, grows to a larger size than Ulmus 
campestris and is perhaps the fastest growing of all Elm trees. An 
Elm of this kind in the deer park of Magdalen College at Oxford, sup- 
posed to have been planted at the time of the Restoration, was blown 
down in April, 1911; it was one hundred and forty-two feet high, with 
a trunk circumference at four feet from the ground of twenty-seven 
feet. This was believed to be the largest tree in Great Britain and 
perhaps in Europe. Ulmus vegeta is a tree with paler bark than that 
of Ulmus campestris, large main branches spreading at narrow angles, 
giving the tree a vase-shaped form, rather pendulous branchlets and 
larger leaves than those of Ulmus campestris, and usually only slightly 
roughened on the upper surface. This tree is not rare in English 
parks and has been largely planted in Cambridgeshire where in the 
neighborhood of Cambridge there are many fine specimens. Brook- 
lands Avenue in that city, planted with this tree in 1830, shows its 
value for such planting, for in all England there is perhaps not a bet- 
ter example of an avenue of planted trees. The Huntington Elm was 
certainly introduced into New England much later than Ulmus cam- 
pestris, and probably the oldest trees here are not more than sixty or 
seventy years old. This Elm is perfectly hardy here, it grows with 
surprising rapidity, and if exotic Elms are to be planted in the United 
States it may well be more generally used here than it has been. 
Persons interested in the plants best suited for the parks and gar- 
dens of eastern North America can find much to learn in the Arbore- 
tum from this time until the end of the year, for it is in the autumn 
that conifers are seen to the best advantage and that the mature leaves 
of the few broad-leaved evergreens which flourish in this climate best 
show the beauty and value of these plants for the late autumn and win- 
ter garden. Perhaps nowhere else are so many different plants with 
brilliant autumn foliage and handsome and abundant autumn fruits 
assembled; and in no other garden can such plants be so easily and 
conveniently studied. Such plants give a character and beauty to the 
autumn garden which can be found only in eastern North America, and
