HORTICULTURAL JOURNAL. 69 
through this house, we find ourselves in a wide lane, consisting of fourteen 
glass-houses, forming a right angle with the walk. All are of the same 
length of ahout a hundred feet, and run in the same direction, from the 
north to the south ; the span-roofs, consequently, facing east and west, a 
situation which, for such houses, is considered the best. Their depth and 
height differs as well as their interior arrangement. If we turn to the right, 
we find, at first, four propagating houses, the first of which is appropriated 
to the raising of seedlings ; the second, to the different processes of grafting ; 
the third, for cuttings of green-house plants ; and the fourth, for propagating 
stove-plants. Then follows the Orchid house, which, besides a choice col- 
lection of these plants, contains the finest tropical Ferns, in great variety. 
The next house is elegantly constructed, its round roof consists entirely of 
wrought-iron ; it contains, on one side, a tan-bed, filled with young Palms, 
on the other, a bed of soil, in which a choice collection of the best hard- 
wooded stove-plants is planted out, to serve as stock for propagation. The 
wide walk in the centre is vaulted by a slight trellis-work, and covered with 
the finest of tropical climbers. The next following lofty building, contains 
the larger Palm trees, and other tropical plants, and is tastefully laid out 
like a winter garden, with serpentine walks. Behind this house, is the 
gasometer of the establishment, which provides with gas the vast offices of 
the "Flore des Serres, etc.," the lecture rooms, refectories, and dormitories 
of the institution, the dwelling house of the proprietor, etc. If we turn now 
to the left side of the lane, we meet, at first, a spacious house, filled with 
coniferous plants. It is also laid out in the style of a winter garden, rich 
in the most beautiful and rarest samples of this now so justly admired 
family. 
Next follow four houses for intermediate and stove-plants, heated from 
six degrees, Reaum. upwards to fourteen. The large number of tropical 
and sub-tropical plants are distributed in these houses, according to the 
amount of heat which they require. The collection is particularly rich in 
plants with variegated or otherwise ornamental foliage, that, even in the 
absence of flowers, such a house always remains interesting and attractive. 
The row ends on this side with two green-houses, one of which serves for 
the wintering of the more delicate and rarer shrubs, the other for 
herbaceous plants, such as Cinerarias, Calceolarias, Verbenas, and others. 
In another direction, we meet now a house, nearly three hundred feet in 
length, with a round iron-glass roof; it is entirely occupied by the extensive 
collection of Camellias. In front of it, are four rows of pits, of equal 
length, also filled with Camellias. In this part of the garden is a large
