hence it was named L. Balliz, and in November, 1898, it received a First- 
class Certificate from the Manchester Orchid Society (O.R., vi. p. 371): 
The flowers have terra cotta sepals, rosy petals fading into white at the 
apex, and a white lip irregularly spotted with carmine. Three other 
hybrids we believe must be regarded as forms of the same, namely, L. ~ 
Mary Gratrix, L. Cappei, and L. Charlesworthii.

e month is a very trying one to beginners, for the climatic conditions 
are very treacherous, cold, piercing winds being generally accompanied 
by brilliant sunshine, which renders. the question of ventilation somewhat 
trying. The following, however, is my system of cultivation: Keep a nice 
warmth in the pipes, and open the bottom ventilators at least a few inches 
on the side of the house not exposed to the prevailing wind. This will 
result in the house being filled. with nice buoyant air, which at the same 
time will not chill the plants. A mean temperature of 55° to 60° Fahr. can 
now be given, since the days are lengthening and the power of the sun also 
increasing. 
‘The Orchids which are growing or flowering will need to, be supplied 
with more water than advised earlier in the season ; but continue to give it 
in sparing quantity to those which are resting or freshly potted. To the 
latter, a gentle spray over the leaves, on bright days, will be found of much 
benefit, whilst to those in full growth or in bud, a good dose every other 
day will probably be needed, but no hard and fast rule can be set down, as 
the weather is so changeable and each house in every locality differs in its 
power of retaining moisture, but the above will serve as a rough guide. 
Two remarks upon watering are, however, so important as to warrant 
Tepetition. (1) When applying water toa plant give a good soaking, never 
a mere sprinkle over the surface ; (2) Always use rain water. Hard water 
invariably leaves a coating of chalk on the leaves and closes the pores so 
that it is impossible for the plant to breathe properly. Damping between 
the pots and on the path may, however, be done with hard water if the 
available supply of rain-water is short, and will now be needed usually 
twice daily, early in the morning and again about three p.m., whilst the 
plants are much benefited by a spraying over their leaves daily. 
Turips.—If the atmosphere is not kept well charged with moisture, 
thrips will make their appearance, and I find the best remedy is to spray 
the piants with a solution of “ Abol” or XL All Insecticide, and also 
increasing the amount of atmospheric moisture.
