morning, when sugaring is finished, it will be as
well to keep your eye on the hedgerows or heaths you may pass, as
occasionally certain insects swarm at an early hour, and now and then
important captures may be made.
Before dismissing the subject of sugaring, it may be as well to say a
few words on lanterns and chip boxes. With regard to the first, bull's
eyes are generally recommended. Possibly, I may be prejudiced against
them when I say that I think they concentrate the glare of light too
suddenly and in too narrow a focus, causing thereby many insects to
drop, which the broader stream of light from an ordinary lantern does
not appear to do to such an extent.
I recommend, therefore, a medium-sized ordinary lantern, about 7 in.
high by 4.5 in. by 3.5 in back to front, fitted with a double-wicked
reservoir, holding sufficient oil to burn seven or eight hours. A
screw cap should be fitted over the burners to prevent the oil running
out and spoiling everything with which the lantern may be packed when
travelling. The usual plate glass door should be made to open from the
front, the glass sides, however, being replaced with bright metal,
converging the rays from a strong reflector at the back; a swing
handle should be fixed at the top and two at the back, all folding
close to the lantern when not in use.
Plenty of ventilation, without allowing actual wind to penetrate,
should be provided, and only the best colza oil be used. If made to
order, a great advantage will be found in having the right-hand side
to open outwards (from the back) instead of opening on the front, as
the lantern can then be more easily trimmed when strapped on the body
without the necessity of its removal for that purpose.
The chip boxes, which some entomologists use instead of the cyanide
bottle to take the moths off the trees, are simply the various sized
ointment boxes of the druggist, strengthened by papering, or by pieces
of glued linen crossing them. Many use them, chiefly those of the old
school, in preference to anything else--De gustibus, etc.
The objections to a general use of these boxes are many. First, you
must provide yourself with a large bagful or pocketful of these boxes
on starting out, as one moth only goes in each box, leaving one pocket
empty on the reverse side of your coat to receive the boxes when
filled, in order not to mix the empty with the full ones. Second, you
are not quite sure at night as to "rubbed" or "chi
