these things have to be borne in mind, together with 
others not mentioned, and the man who is on the 
spot must make his calculations accordingly. Usually 
a fruit- to every nine inches of superficial area covered 
by the tree would be considered a good crop. 
Whether your plant is strong enough to be equal to 
this task you must judge.

CLEMATIS INDIVISA. 
While Clematis montana from the Himalayas is 
now flowering profusely on open walls and houses, 
the more beautiful C. indivisa from New Zealand is 
making an equally interesting display under glass. 
Curiously enough it is not so hardy as its Himalayan 
congener, a circumstance which would probably 
depend upon the altitude at which the respective 
species grow in their native habitats. 
space over the entrance to a cool Fern rockery or 
cave, the door of which can be discerned towards the 
left of the picture. When in bloom, the plant makes 
a gorgeous display. By its removal in summer, 
more space is afforded the numerous other climbers 
here, so that the scene is changeable, and a greater 
amount of variety secured. Ths temperature in the 
corridor is never above that of a cool greenhouse.

SPRING FLOWERS AT CHELSEA. 
During the latter end of the past week the cold 
winds blowing from the north, and the heavy clouds 
at times obscuring the skv, and shutting out the 
sunshine, reminded us more of March than May. 
The inside of a large number of the houses in the 
nursery of Messrs. J. Veitch & Sons, Chelsea, on the 
contrary reminded us of summer notwithstadinng 
flowers on a scape were also noticeable. C. 
schilleriana with its rich purple-lined lip, and the 
charming C. dolosa, were notable for the size of their 
flowers which appeared out of all proportion to the 
size of the plants. The latter are soft pink with a 
large white blotch cn the lip. The flowers are 
remarkable in being produced on a growth quite 
separate from the fully developed pseudobulb. 
Laelia purpurata is also a feature of this house, and 
though the lip is always darker than the rest of the 
flower, there is considerable variation in the shades 
of colour in different plants. 
The Orchid rockery is also well worth inspection 
at present. Very conspicuous were the numerous 
well-flowered specimens of Dendrobium thyrsiflorum 
on the occasion of our visit. On the higher reaches 
of the rockery they formed a line surrounding the 
house like sentinels on guard. From the roof of the 
Clematis indivisa at Falkland Park, 
A greenhouse temperature is necessary for C. 
indivisa to give entire.satisfaction. Our summer suits 
it admirably, however, and taking advantage of this 
fact Mr. A. Wright, gardener to T. McMeekin, Esq., 
Falkland Park, South Norwood Hill, has adopted a 
plan by which he secures more advantages than one, 
A hole has been provided near the ground line of the 
long corridor in which the plant is grown, and 
through this hole the stems and branches are trans¬ 
ferred to the open air after the flowering period is 
over. Here they are trained along the eves of the 
houses, and make excellent growth during the 
summer months. The young wood ripens well 
before the whole plant is again drawn through the 
opening into the interior of the corridor for the 
winter. The accompanying illustration, which has 
been prepared from one of Mr, Wright's photographs, 
shows the plant in full bloom. The branches are 
trained over the roof at one end of the long corridor, 
covering a great part of the back wall, as well as the 
the cold, drying and unseasonable winds. Some o t 
the occupants of these houses we will essay to 
describe. 
Orchid Houses. 
Every season has its own characteristic Orchids, and 
for the next two months at least the kinds will be 
both numerous and varied. As chance would order 
it we passed through the Cattleya house first and 
witnessed a considerable number of kinds many of 
them in quantity. Cattleya Schroderae is quite the 
leading feature of the house at present, and dis¬ 
tributed all over it. Very charming was a variety 
having both sepals and lip goffered and crisped to 
a remarkable extent. The lip of another was flatter 
but large with a rich orange, almost diamond-shaped 
blotch in the throat. At the opposite end of the 
house was a great bank of plants of beautiful varieties 
differing considerably in colour. Numerous pieces 
of the fragrant C. citrina were suspended from the 
roof. C. lawrenceana and C. Skinneri, with ten 
house basket plants of Oncidiunj ampliatum majus 
and O. marshallianum made a fine display with their 
gracefully arching and drooping panicles of large 
bright yellow flowers. Dendnobium devonianum 
with charmingly-fringed flowers, and D. lineatum 
with four long racemes of bloom were very con¬ 
spicuous. The massive blood-red and white flowers 
of Maxillaria sanderiana have never yet been beaten 
by others of the genus. Passing into the warm 
house we found species, varieties and hybrids of the 
popular Cypripediums in great numbers, but as we 
noted a number of the finer things on the last 
occasion we need not detail them at present. 
The cool houses were gay with a wealth of popular 
sorts, that find their way into every collection. O. 
crispum exhibited many round flowers in various 
shades of white, rosy-tinted and blotched arrange¬ 
ments of colour. Other species included O. luteo- 
purpureum, O. Pescatorei, O. cordatum, O. 
maculatum, and O. andersonianum. The scarlet
