The Eggs or Nits are white, and having when spawn’d a clammy glutinous Substance, they flick to any thing spawn’d upon, and by Heat come to Maturity and Life. The Eggs are oval, and as small as the smallest Maw-feed. Buggs of one day old, are white as Milk. At three days old, are Cream-colour’d. At one Week old, are Straw-colour’d. At two Weeks, are of the same Colour, with a red List down the Back. At three Weeks, List Copper Colour. At four Weeks, List Browner. At five Weeks, List deeper Brown. At six Weeks, the Sides brown, and the List hardly discernible. At seven Weeks, they come to be of their proper Colour, all over brown. At eight Weeks, they grow bigger. Nine Weeks, Ditto. Ten Weeks, Ditto. At eleven Weeks, they are full grown. _Vide_ the Plate done from _Europeans_ bred: under which is a single one longer and larger, than our full-grown, being a full-grown _American_ bred. ’Tis needless to give the Gradations of that Species, because when they spawn and breed here, the Young degenerate, and are of the _European_ Size. As I wrote down the Time I put up all Pairs for breeding, and also the Times they spawn’d, and observ’d and set down the Numbers they generally spawn’d; I found by my account of above forty Pair so put up with various Foods, not only their best-beloved Foods, but also their Method of Breeding; of which, to render my Observations of publick Service, I shall give you an account. _Viz._ Their beloved Foods are Blood, dry’d Paste, Size, Deal, Beach, Osier, and some other Woods, the Sap of which they suck; and on any one of these will they live the Year round. Oak, Walnut, Cedar and Mahogoney they will not feed upon; all Pairs I put up with those Woods for Food, having been soon starved to death. Wild Buggs are watchful and cunning, and tho’ timorous of us, yet in fight one with another, are very fierce; I having often seen some (that I brought up from a day old, always inur’d to Light and Company) fight as eagerly as Dogs or Cocks, and sometimes one or both have died on the Spot. From those so brought up tame, I made the greatest Discoveries. They are hot in Nature, generate often, and shoot their Spawn all at once, and then leave it, as Fish do. They generally spawn about fifty at a time, of which Spawn about forty odd in about three Weeks time usually, (but sometimes two or three days more or less, according as the Weather proves more or less hot) come to life; the Residue proving addle, as do often the Eggs of Hens, _&c._ Thus they spawn four times in a Season; _viz._ in _March_, _May_, _July_, and _September_: by which ’tis apparent to a Demonstration, that from every Pair that lives out the Season, about two hundred Eggs or Nits are produc’d; and that out of them, one hundred and sixty, or one hundred and seventy, come to Life and Perfection.
