Pliny affirms, that the galls break out all together in one night, about the beginning of June, and arrive to their full growth in one day; this I should recommend to the experience of some extraordinary vigilant wood-man, had we any of our oaks that produc'd them, Italy and Spain being the nearest that do: Galls are of several kinds, but grow upon a different species of _robur_ from any of ours, which never arrive to any maturity; the white and imperforated are the best; of all which, and their several species, see Jasp.

Bauhinus, and the excellent Malpighius, in his Discourse _de Gallis_, and other morbous tumors, raised by, and producing insects, infecting the leaves, stalks and branches of this tree with a venomous liquor or froth, wherein they lay and deposite their eggs, which bore and perforate these excrescences, when the worms are hatch'd, so as we see them in galls.
What benefit the mast does universally yield (once in two years at least) for the fatting of hogs and deer, I shall shew upon another occasion, before the conclusion of this Discourse.

A peck of acorns a day, with a little bran, will make an hog ('tis said) increase a pound-weight _per diem_ for two months together.

They give them also to oxen mingled with bran, chop'd or broken; otherwise they are apt to sprout and grow in their bellies.

Others say, they should first be macerated in water, to extract their malignity; cattle many times perishing without this preparation.
