In speaking of the shrubs of the Arnold Arboretum I shall 

 sometimes mention specimens I noticed in Professor Sargent's 

 private grounds at Brookline, one mile nearer Boston, as some 

 rare and beautiful examples there are older than those in the 

 Arboretum. Some interesting trees and shrubs I noted also in 

 Mr. Hunne well's grounds near Wolseley, a splendid and beauti- 

 fully kept garden, but also of comparatively recent date — not 

 more than thirty years old at most. 



The time of my visit was the end of June and beginning of 

 July — the very best time, according to the Professor, to go 

 through the Arboretum. 



The future position of the Magnolia tribe will be a very 

 favourable one, close to the Museum building and to the entrance 

 nearest Boston. The spot has just been deeply ploughed and 

 trenched. Magnolias are as yet only to be met with as young 

 specimens in the Botanical School of the Arboretum. Among 

 these the best, as to the number and symmetry of the limbs and 

 the density of foliage, seems to be the M. Kobus from Japan. The 

 tree is very hardy. I saw it in Meehan's Nurseries, near Phil- 

 adelphia, grafted on M. acuminata. A new introduction from 

 Japan is Magnolia parviflora. In France the newly imported 

 plants flowered on their arrival, but have refused to flower since. 

 At the Arboretum the specimens are grafted on M. acuminata, 

 and bloom every year. The Cercidiphyllum is a beautiful member 

 of the Magnolia family. With us in France it seldom succeeds 

 well, the new shoots being often cut by the late spring frosts, 

 or the young tree scorched and burned by the summer sun. 

 Here, near Boston, I found splendid young trees, 18 to 20 feet 

 high, and without a dead leaf upon them. They are planted on 

 the northern side of the groves, and in such position they are 

 branched nearly to the base, without a single fault, and are very 

 beautiful. The choice of such a position is quite logical. The 

 tree will germinate and develop in its native country in dense 

 and moist woodlands, and never have any part exposed to the 

 sun except quite the top branches. The rainfall in Japan is 

 heavy, and in our drier climates it is absolutely necessary in some 

 way to prevent the excessive dryness of the soil, and even of the 

 atmosphere near the tree, and the sun from scorching the young 

 stem ; hence a northern aspect and the preservation of all the 

 lower branches are desirable. The climate of New England seems
