to climb trees or rocks, and if necessay, to wade in brooks, ponds, or bogs. 

 His eyes must be able to detect a minute moth, as it flits by in bright 

 sunshine or twilight, or a larger one in midnight darkness ; to observe 

 traces of insects in a plant, tree, bark or wall crevice, and in tlie thou- 

 sand and one other places which conceal them ; to stand, too, the 

 bright glare of a summer sun, ou burning sand or sparkling sheet of 

 water, and to distinguish at a glance whether or not a captured speci- 

 men is worth taking. In his rambles he must often endure besides, 

 fatigue, hunger, thirst, and wet clothes ; and at home he wiU spend 

 many weary, though pleasant hours, in setting out his captures, and 

 arranging his collections. Occasionally, also, a cross-grained farmer, 

 gamekeeper, or " official," will warn him from his hunting ground, 

 sometimes with reason, though more frequently without cause. A 

 host of other annoyances, such as children flocking round him; occa- 

 sionally vicious buUs or savage dogs, yelping curs, flies, gnats, prickly- 

 bushes and thorns, assault him on all sides. Ou his arrival at home, 

 he should proceed without delay to kill his stock. All moths, except 

 green ones, which do not measure more than one and a half 

 inches, may be smothered with sulphur without much injury. 

 If a number of pill boxes containing specimens, be placed under a 

 glass shade, with the lids slightly raised, and the fumes of half a dozen 

 lucifer matches be allowed to pass into the shade, the moths con- 

 tained wiU be ready for setting in the course of half an hour. If 

 removed from the cause of death too soon, many will revive and 

 spoil themselves with fluttering. Chloroform may be used witliout 

 injury to colour, and is therefore useful in the case of green insects 

 which are spoiled by sulphur. The volatility of chloroform makes it 

 dangerous if used carelessly ; and if administered in too strong doses, 

 the moths are made too rigid, and cannot therefore be set. Large in- 

 sects may be killed either with chloroform or by being pierced under 

 the wing with a sharp spike dipped in a strong solution of oxalic acid. 

 When dead, the specimens may be taken from the bo.xes and assorted 

 preparatory to setting. Each of those which are good, must have a 

 suitable pin pushed straight through the thorax until a moderate length 

 of it appears ou the underside. When all are pinned, arrange them on 

 setting boards suitable in size, and then place the wings in the desired 

 position by means of fine pins, and retain them there till dry, with fine 

 thread or paper. The setting boards should be of various sizes, adapted 

 to the size of the insect, and should be long enough to hold from one 

 to six specimens. They should have an arched surface to impart a 

 graceful curve to tlie wings, and a groove down the centre to admit the 

 bodies.
