Northern China and northern Japan having climates simi- 

 lar to om' own, for similar reasons furnish many trees suited 

 for our plantations, some of which have been successfully 

 tried. The region of the Caucasus has furnished two excel- 

 lent trees likely to continue of value, — the Picea orientalis 

 and Abies Normaniana, — while others have been introduced 

 from Siberia, Turkestan and Thibet. Among such trees we 

 have the Horse Chestnut, which has proved itself exceedingly 

 desirable for certain situations as an ornamental tree, possess- 

 ing a stateliness unsurpassed by almost any other tree, and 

 furnishing, too, a magnificent show of flowers in the latter 

 part of the month of May. 



Among the trees from the Pacific glope are some, however, 

 which have such an extended range that, selecting specimens 

 or seeds from the extreme limits of their dispersion, we are 

 enabled to introduce them successfully here. Two such 

 trees are the Douglas Fir and Picea funo;ens or the Blue 

 Rocky Mountain Spruce. These trees, although not hardy 

 when taken from California or when imported from Europe, 

 have proved themselves perfectly hardy when introduced 

 from Colorado. Specimens of both these beautiful trees 

 may now be seen in the neighborhood of Boston, twenty 

 feet hiiih and of beautiful form and o-rowth. 



Of the European trees which succeed well in this climate 

 may be mentioned the English and Dutch Elms, the Euro- 

 pean Larch, Norway Maple, and the White Willow. These 

 species are of wide range, and seem to flourish in all regions. 

 The English Elm has proved, for city streets, a better tree 

 than the more graceful American Elm, although for suljurban 

 planting the American species has no equal. It is to be 

 regretted that the desire for quick results has caused, in 

 recent years, the use of the Maple to the exclusion of the 

 Elm, in many of our villages, and the day is not far distant 

 when those beautiful village streets with their arching Elms 

 will be only known in picture and tradition. 



The Norway Maple, while resembling our Rock Maple in 

 general appearance, has a larger leaf and fuller, deeper 

 green foliage, and for an ornamental tree is desirable, on
