306 THE ENTOMOLOGIST. 
using indoor light is great; the window is easily lighted up, and 
again extinguished if not attractive, and all the necessary para- 
phernalia is at hand. Various are the modes and apparatus used ; 
and although every collector may employ those means which his 
fancy dictates, from the solitary candle to the electric light, I shall 
only describe the light which I have used, and the rules which 
have guided me for some years, with success, in various country 
districts. 
The Room.—When available, an empty room is the best, with 
white walls; if there are two windows in it, either light up both 
or darken one; but two windows having different aspects are 
excellent, if both are lighted, and plenty of help present. There 
must be no window of another room, facing the same direction, 
with a ight showing; any outside light is fatal, either from other 
houses or gas-lamps. 
The Window.— This should always be an upstairs one, but 
not over a glass verandah or conservatory, as these cause reflec- 
tion, and the moths are apt to settle on the glass, and not come 
up to the light. Sash-windows are the best, but I have used 
French windows on the ground-floor successfully enough. When 
a bow-window is used the sides must be darkened. Some of the 
most prolific nights that I ever had were in a large whitewashed 
stable-loft, with the window taken bodily out. Casement-windows 
are the most unsatisfactory. Whatever kind of window is used, 
I find it best to have it as wide open as possible, and let the insects. 
come well into the room, when they can be either netted or boxed 
at once. 
The Situation. —The window should overlook as open an 
extent of lawn, field, or moor as can be obtained, and if there is 
a wood in the vicinity, so much the better. The aspect of the 
window is of no great importance ; I have, however, found N. and 
W. the best. 
The Light.—Outside and just under the window I hang one 
of Messrs. Watkins and Doneaster’s excellent benzoline lamps ; 
on each side (also outside), a strong carriage-lamp; on a small 
table, placed opposite the centre of the window, alamp with a most 
powerful reflector; and immediately behind this, but standing 
higher, a lamp of fifty-candle power. These together throw an 
immense volume of light; every shrub, conifer and hedge within 
two or three hundred yards throws its shadow, and the light is 
seen at a great distance, the outside lamps extending widely the 
semicircle of light. My experience has been that the stronger 
the light the greater the result. Always have another lamp on 
the wall opposite the window, as moths when in the room will at 
once fly towards it. Be most careful to see that there is no oil 
on the outside of the lamps, and use wire-gauze tops over the 
chimneys. 
The Time.—May 15th to 81st, 10 p.m. to 12; June, 11 p.m.
