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 Lepidoptera. 

 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
