Pits and Frames .—The instructions given last month will servo for this. 
Keep the pits and frames as dry as possible ; give air at every favourable 
opportunity ; and cover well up in frosty weather. Few plants will then suffer 
much. 
Oiit-Doors .—The work here will depend on the state of the weather. If 
severe weather sets in, see that everything that requires it is well protected. As 
loefore recommended, alterations and the planting of hardy trees [and shrubs 
may be proceeded with in fine weather. Novv’ the leaves are all off, every place 
should be well swept, and the leaves collected into heaps for compost.—M. Saul,

THE VICTORIA ELECTRIC THERMOMETER. 
EGULARITY in the temperature of plant-houses, especially those which 
are devoted to the culture of tropical plants, and to forcing, is so 
important a point in plant-culture, that any means of ascertaining and 
^ thus of checking irregularity, must be a great boon to the gardener, 
since it would be calculated to relieve him from the pressure of anxiety on this 
very important matter. It is as one means to this end that I have designed the 
Victoria Electric Thermometer, of which a figure is annexed. 
It will be seen that the instrument consists of a peculiar form of balance 
thermometer, designed with the object of bringing into contact the wires of a 
galvanic battery, and, by the electric current thus set up, indicating either a rise 
or fall in the temperature of the house in which the apparatus is placed. This is 
effected by the ringing of a bell, or by other means.
