ingle crown with a bit of the rootstock 
attached. This, of course, required bot- 
om heat to encourage roots, and some 
if the plants damped off. Since then a 
nuch easier system has been discovered. 
The old plants are left in the pots, the 
ilder and withered leaves are removed 
: rom the bottom, and a light compost con¬ 
sisting chiefly of leaf-mould and sand is 
made up and heaped round the neck of 
the plant. This is frequently watered to 
encourage the production of roots from 
the upper portion of the short stems. A 
warm house, of course, is necessary to 
encourage roots and prevent damping. 
In the course of a few weeks it will be 
found that young roots have been pushed 
into the fresh soil in great abundance. 
The whole ball of soil can then be turned 
out of the pot and the plant severed from 
the old roots by cutting the neck of the 
plant just under the young roots which 
have been made. By this means each 
crown will be found to come away bodily 
from the old plant with its own roots at¬ 
tached and some soil. The process of 
mounding up the old plants is shown at 
F, while a young plant with roots attached 
is shown at G. Each should be potted up 
separately in a pot of suitable size, so 
that.it may be given another shift during 
the growing season when it has got well 
established. 
The diagram at H show's a suitable com¬ 
post, W'hich might consist of three parts 
of good fibrous loam to one part of leaf- 
mould, one part of cow manure, well 
rotted and rubbed up fine, one part of 
sand, nearly one part of burned refuse, to 
give porosity to the soil, and about one- 
fifth part of some artificial fertiliser. 
This last, and even the cotv manure, 
might be left out until the second potting, 
w'hen the plants are well established. 
Odontioda 
Bradshawiae 
Cookson’s var. 
At the meeting of the R.H.S. on the 
gth inst. a new and remarkably handsome 
bigeneric hybrid Odontioda under the 
above name was exhibited by N. C. Cook- 
son, Esq. (gardener, Mr. H. J. Chapman), 
Oakwood, Wylam-on-Tvne. It is sup¬ 
posed to be "the reverse cross from O. 
Bradshawiae, but there is some uncer¬ 
tainty about it. The parents are put down 
as Odontogiossum crispum crossed with 
Cochlioda noctzliaha. The sepals are 
scarlet wdth a white tip and violet-purple 
edging. The petals are much broader and 
nearly covered with scarlet, but the tip is 
more coloured like the violet-purple edg¬ 
ing. The lip is variegated with scarlet,, 
orange, white and”purple, w'hile the crest 
is golden-yellow and made up of long, 
finger-like fringes. The flower measures 
3 in. across the long-way of it. It is the 
most handsome and remarkable variety 
of the hybrid which we have seen. The 
ordinary’O. Bradshawfiae has flow'ers of a. 
uniform, light orange-scarlet, wfithout the 
handsome lacing of this new variety. A. 
First-class Certificate was deservedly 
awarded this handsome hybrid. The il¬ 
lustration w r as prepared "from a photo¬ 
graph sent us by Mr. Chapman, and shows> 
the form and size of the flower. 
The Flower Garden. 
East Winds and the Lawns. 
During the month of March east winds 
leave their effect upon our lawns. The}' are 
more prevalent in some seasons than in others 
and so shrivel up the grass more, but it is 
only the older blades of grass that suffer. 
Alread}' we have had a very long spell 
of east winds, accompanied by brilliant sun¬ 
shine in the daytime and followed by severe 
frosts at night. JS t ow, there are not any 
weather Conditions that are more likely to 
prove harmful to tender plants and trees, 
and lawns which are exposed to such quickly 
assume a brown appearance, but it is the ofd? 
grass which suffers, and no real harm is 
done. Young grasses, so exposed, would be 
injured, but the time for the latter has not 
quite come. So amateurs need not be 
troubled at the brown appearance of their 
exposed lawns, but get their mowing 
machines ready, with knives and cylinders 
clean, bright and sharp, then they will cut 
off the old tough grass easily enough. 
At this season there is a good opportunity 
of getting rid of much moss on lawns. 
Where moss is troublesome and it is not 
convenient to put down drains, advantage 
should now be taken of its dried-up condi¬ 
tion to get rid of as much as possible by 
raking it up with a sharp-toothed iron rake. 
A Rich Lawn Dressing. 
After collecting as much of the moss as 
vou can, put on a dressing of wood ashes 
at the rate of one peck per square rod of 
ground—more would, be beneficial, but as 
the material is very difficult to obtain I men-
