Cattleyas, Laelias, or Odontoglossums, they may be kept clean by syring¬ 
ing them twice daily. With us this insect was most troublesome until 
we practised a liberal system of syringing and careful ventilation, and 
since then—that is, for the past five or six years—we have never been 
troubled with it. From the present time plants may be lightly syringed 
about 14 inches high, and has seven main roots, some of which hang 
nearly 4 feet below the basket, and measure in all over 50 feet. A. 
Lobbi has rooted equally as free, but the roots work more about the 
basket, and cling to the charcoal and sides very firmly. Saccolabium 
ampullaceum has rooted equally as free as A. virens according to its size

over the foliage daily, while it may be used liberally in the Odontoglossum 
house twice on bright days ; on dull or wet ones the houses should only 
be damped. In short, never syringe on such days that air cannot be 
admitted at the top of the house. 
To show how these plants flourish and root under the free use of the 
syringe, a plant of Aerides virens may be given as an example. It is 
growing in an 8-inch basket filled with charcoal and crocks, with a little 
moss on the surface and round the sides to maintain moisture about the 
plant, not its roots, for they are all out of the basket. The plant is 
of growth. Oncidium Lanceanum had amass of roots 2’to"3 feet below 
the basket, bHt this unfortunately fell from the roof, and the majority 
of the roots were destroyed, but many of them are again nearly 2 feet 
in length. These arc only given as examples of the manner in which 
Orchids root under the syringing system. The plants alluded to have 
been more or less syringed all the year, for they are growing in the stove 
suspended with Crotons and other plants. The water used for syringing 
should always be warmer than the temperature of the house, or spot 
and other injurious results may follow.— A Northerner,
