As to the best means of producing the most suitable conditions for the 
plants I can say but little more here, as, knowing what an important matter 
it is, I have devoted considerable space to the subject in previous Calendars. 
I may} however, just mention the matter of protection from cold during 
winter, which seems to be a most seasonable subject, and one which should 
not be forgotten. To cover the roof glass with garden mats or something 
similar during rigorous winter weather, especially at night time, is not only 
a great saving in fuel, but at the same time results in much more healthy 
conditions within the house. The ends of the structure also, which are of 
glass, are sometimes fearfully cold and damp places, and although light is 
always of great importance, yet I do not hesitate for one moment when 
necessary to mat up such ends permanently during the worst.winter months. 
The roof covering should, for obvious reasons, be conveniently arranged 
for putting on and off night and morning. 
During December flowers are naturally scarce, and those which bloom 
this month are highly prized. It is fortunate that there are a good many 
species to come in at this dull period. The Cattleyas labiata and Bowringiana 
being now past, are replaced with the deciduous Calanthes, which will, 
together with the Mexican Lzlias, continue to make a very useful show for 
some time tocome. Calanthes this year have been affected with a consider- 
able amount of black spot on the foliage and pseudobulbs. It is a sort of 
disease to which this species is susceptible, and which seems to give more 
trouble in some localities than in others, for which I am unable to suggest 
areason. The cause of its abundance this season may probably be traced, 
as in the case of the Dendrobiums, to the bad summer of 1894 and the late 
terrible winter. The summer through which we have just passed has, how- 
ever, seemed to work miracles in the way of counteracting the previous evil 
influences. Take, for instance, the Dendrobiums, which have finished up 
their season’s growth much more satisfactorily than at one time seemed 
possible, The Calanthes have also done better than the early part of the 
season seemed to warrant ; indeed, it seems to me that the flower spikes will 
be very little, if any, below the average standard. The same may be said 
respecting the Mexican Lelias, such as L. auceps in variety, L. autumnalis, 
L. furfuracea, L.albida, L. x Gouldiana,and L. x Eyermaniana. Their first 
attempt to grow in the spring caused some little uneasiness, but as the 
summer wore on disquieting doubts soon became lessened, for with an 
abundance of light and air they quickly responded, and the splendid month
