Take a _Fly_ out of your Box: see if the Pin be run through it perpendicularly: if so, stick it on one of your setting Boards, and with the Point of a Needle (which must be fixt into a small Stick, or what else you like best) extend one Wing leisurely, till such Time as the Point thereof is even with the Nose of the _Fly_ you are setting. That done, fix one of your Card Braces gently on that Wing, to prevent its giving way; serve the other Wing in the same manner, and your _Fly_ will appear extended as in the Paintings. Let the Braces remain on the Wings of _Butterflies_ a Fortnight, on those of great _Moths_ a Month. Take Notice, however, that a great Number of small _Moths_ must be set in your Boxes in the Field, otherwise your labour will be lost; you’ll presently know which these are, by observing them to be dead and almost stiff; so that it is proper to carry always about you a little Box of Card Braces for this Purpose. _The Way to preserve your ~Flies~, after you have taken them from your Setting Board._ If you put them in Drawers, Boxes, or Frames with Glasses before them, its proper to get some Camphire, which inclose in small Muslin Bags, and fasten it to those Places where your _Flies_ are; by this Means you will destroy those Insects that would otherwise injure your _Flies_; and by renewing now and then this Method, I am convinced your _Flies_ may be preserved several Years. The Months in _England_ that produce the greatest Variety of _Flies_, are _April_, _May_, _June_, _July_, and _August_, especially of the _Butterfly_ Kind; and for _Moths_, I am of Opinion, that there are many different Species produced all the Year round. The best Time to take the greatest Variety of _Moths_, is for one Hour after Sun-set, and the properest Places are in and by the Sides of Woods, Gardens, Green Lanes, _&c._ where with your Net you’l seldom fail of Sport. Thus much seemed necessary to say in Respect to taking _Insects_ in the _Fly_ State, and more would be superfluous. _But as it may be agreeable to some to breed the ~Flies~ themselves from the ~Caterpillars~, I shall likewise give the best Instructions I am able for that Purpose._ In the Spring and Autumn Season you may collect great Variety of _Caterpillars_, by spreading a Sheet under _Oak-Trees_: then beating the Boughs, many _Caterpillars_ will fall, which if taken Care of, will produce scarce and valuable _Moths_; you may also obtain by the same Means _Caterpillars_ from the _Black-Thorn_, _White-Thorn_, _Bramble_, _Chickweed_, _Willow_, and many other Growths.
