of my visit, the s of June, the Dyer's owe eem Genista tinctoria, 
an European plant introduced into North America, where in some 
districts it has now ral possession of erit of aeres of dry land, 
made a brave show with its yellow flowers. Some of the earlier golden- 
rods, Solidago canadensis, &c., were also fine, and Rosa humilis, a red 
flowering, dwarf-growing bush, was conspicuous.  Beróeris Thunbergi, 
various species of Rhus, Myrica ceriferu, Comptonia asplenifolia, 
dwarf willows, dogwoods, viburnums, &c., with Clematis and Vitis 
and other climbers growing at will over their neighbours, form 
tangle which produced perfectly natural and very beautiful effects. 
The knife is freely used in the neighbourhood of the trees which are 
intended to develop; in the meantime the undergrowth is very 
attractive, and it keeps the ground cool and moist round them. One 
triking as well as beautiful features of the Arboretum is 
Hemlock Mount, a steep rocky hillside, the north side of which is 
clothed with fine hemlock eit from two to three hundred years old.

mentioned is covered wit] various native oaks and other trees self-sown, 
when removed, and a third self-sown series which are ready to spring 
into the second rank. The axe is used to prevent one tree from 
damaging its neighbour, and the ground is carpeted with Vaccinium 
pennsylvanicum, and other native shrubs, as well as kerbaceous plants, a 
number of which are cultivated in English gardens. 
The large trees on the lower ground have been rejuvenated by 
pruning, and it is surprising to find what a change has been wrought in 
a few years by hard cutting-in of the branches , top-dressing of the 
surface soil, and by the removal of old worn-out trees which were too 
thick to allow sufficient light and air to reach the ground, 
In the Hemlock wood I noticed growing wild along the side of a 
brook the spikenard, fear sepa a stately herbaceous plant, well 
known for its arom large r the skunk cabbage (Symplo- 
carpus fetidus), the lady fern, the Todien turnip (Arisema ; triphyllum), 
Baptisia tinctoria, Aster cordifolia, and a host of other species which 
are cultivated for ornament in British pres Higher up the wood 
grew the bracken (Pteris aquilina). The American Fig of this 
widely distributed fern differs a good deal fim the British one in its 
darker green, more leathery, less-cut fronds. Mosi bifolium, 
Smilacina racemosa, Desmodium canadense, and Hypoxis erecta, a 
pretty little amaryllid with grass-like ieaves and yellow flowers, were 
also noted. Rubus occidentalis, a bramble gan m by reason of its

The igi eollection of shrubs is slanted i in long beds with walks 
between, and occupies a considerable area. It is exceedingly rich in 
s and varieties, and includes every woody plant in cultivation in 
the United States which is hardy in the eighbonrhood of Boston. In 
the nursery attached to the Arboretum is a very rich series of Japanese 
plants, the result of an extended permis Ac through. Japan last year by
