rooting, and require a good supply of moisture during the growing season, which 
commences when their flowering is over. We find this an excellent time for repotting 
them should they require it; if not, a little fresh material placed about their new 
roots will benefit them. These plants require shading from the hottest sun, or their 
foliage will soon be affected, which will not only interfere with their progress but 
greatly injure their appearance. They will grow well in the Odontoglossum house at 
the warmest end; indeed, more warmth than they can obtain there would not harm 
them. They must be kept free from insects. They are propagated by dividing the 
plants just as they begin to grow, potting the divided pieces in the same material as 
that described above, and not giving much water until they begin to push forth their 
growth and make roots. 
Construction or Orcurp Hovsrs.—One of the most important items in Orchid 
culture is that of the construction of the houses for the reception of the plants. 
Sometimes these structures are joimed together or placed side by side with a gutter 
running up the central space between them. Such houses are difficult to get at, and 
glass is frequently broken through the difficulty in passing along the gutters to 
repair or paint the sashes. But even this, though inconvenient and expensive, we 
do not consider the chief evil of such a mode of construction. We maintain that 
there should be a passage-way of three feet or more in width between the houses, 
so that a free circulation of air may be obtained; and then, if they are span-roofed, 
ventilators can be placed in the brickwork in order to secure bottom ventilation, 
which is required equally with that at the top to keep the plants in_ perfect 
health. We have always adopted this plan, and have found it most convenient 
and useful for regulating the temperature of the house. It is sometimes argued 
that in building two walls we incur an extra expense, but we think the first 
expense is the best, and we know that it is soon saved by the facility of access 
to each house separately, by avoiding the expense of the gutters and the incon- 
venience of getting at the glass for repairs. The tradesmen’s bills will show which is 
the best and cheapest plan in the end. Those gentlemen who go to the expense of 
having houses built, of purchasing plants, and of keeping men to look after them, 
should not object to lay out a little extra money on the structures for the well-being 
of the plants, and as they gain experience they will be able to see the difference 1» 
the progress of their plants. Those who may think it worth while to act accord- 
ing to these few simple suggestions will find their reward. It is always desirable 
to try to avoid whatever is detrimental to the growth of the plants, whether they 
are valuable ones or not, for complete success not only gives one greater pleasure 
but is far more satisfactory both to employer and employed.—B. 8. W.
