f llR Holders are so constructed that they will receive any sized Tlierinoineter. By taking hold 
of the ladder and drawing it out, turning the pointers back, and hanging the Tlierinoineter on 
the projecting knob in the centre of disc, and pressing the ladder to until the side wires are 
level with the face of the Theriiioineter, and turning the pointers on to the face of the glass, 
they will not only indicate the required temperature, but will help to keep the glass in position. As 
will be noticed in the engraving, the words “ day ” and “ night ” are stamped on the pointers, which 
slide np and down the wires to indicate the maxiniiiiii or minimum heat required. For instance, in 
the forcing season say, a vinery sbuted at a day temperature of 60 deg., night o5 deg. ; all one has 
to do is to move the pointers on to the figures, so that the man who is in charge of the house or 
heating ap]ia tutus will have no cause to trouble the gardener as to temperature required, hence doing 
away with the old-fashioned plan of writing ticket® or labels. The dise at the top also has a pointer, 
which is moved by the projecting knob that the Thermometer hangs on. This is to indicate the 
degree that the honse may run uji to by the sun beat. 
'J'hese Holders are not merely useful but ornamental, as the disc ami jiointers are made in brass 
with figures embossed, therefore, giving the Thermometer a much neater and better appearance.
