is no better tool for this and other purposes than Mr. 
Samouelle's digger, which consists of an iron five inches 
long, rather more than one-third of an inch in diameter, 
forming a curve towards the extremity, terminating in a 
lozenge-shaped point, and strongly fixed in a wooden 
handle 3 . With this you may not only explore the in- 
terior of timber-trees, but grub up the turf under them, 
and examine the earth for the pupae of Lcpidoptcra. 
When your object is merely this latter purpose, a po- 
tato-fork — which is better than a spade, as it will seldom 
injure the pupae — will be your best implement. 
2. Next have a stick, to resemble a common walking- 
stick, sufficiently stout to beat the branches of the trees 
and shrubs, fitted at one end with a male screw, and at 
the other with a female, with a brass cap to screw over 
each to keep the dirt from them. Besides this, you may 
carry with you a spare piece or two about a foot long, 
properly equipped to screw to it when you want to 
lengthen it. 
3. Another implement must be a bag-net b . This con- 
sists of a hoop of stout brass wire about nine inches or 
a foot in diameter, with a socket to receive the end of 
your stick, or, what is more secure, a screw to fix it to it, 
with a bag of gauze, muslin, or fine canvass, about twelve 
inches deep, sewed round it. The French collectors 
use a net of this kind, in which the hoop is formed of 
two semicircular pieces of iron or brass wire hooked to- 
gether at one end, and at the other made to lap over the 
corresponding piece, and pierced to receive the screw at
