120 * Of Vegetables. 
The feeds of avens have one fingle hook, thofe of agri¬ 
mony and goofe-grafs many, both the former loving a 
warm bank, and the laft a hedge for its fupport; on the 
contrary, divers feeds are furnifhed with wings or fea¬ 
thers, partly with the help of the wind to carry them 
when ripe from off the plant, as thofe of afh, maple, 
orach, &c. leaft flaying thereon too long, they ftioulcj 
either be corrupted, or mifs their feafon, and partly to 
enable them to make their flight more or lefs abroad; 
that by falling together, they may not come up too thick, 
and if one fhould efcape a good foil or bed, another may 
fight thereon. The kernels of pine have wings, not 
unlike thofe of fome infects, but very fhort; in refpedt of 
the weight of the feed, they do not fly into the air, but 
only flutter about upon the ground j thofe of typha dan¬ 
delion, and moft of the papous kind, with many more, 
have very long, and numerous feathers, by which they 
are wafted everywhere, and to any convenient diftance. 
Some feeds are flatter’d, not by flying abroad, but by 
being fpurted away as wood-forrel, fig. 437. which is ef¬ 
fected by a white, thick and ftrong cover of tendons of a 
fpringy nature, in which the feed within its cafe is in- 
clofed. This cover, as foon as it begins to dry, burfts 
©pen in an inftant, on one fide, and is violently turned 
infide out, and fo fmartly throws off the feed. 
The feeds of harts-tongue, fig. 439. and all that tribe, 
are flung or fhot away by a curious contrivance in the 
feed-cafe 5 as in codded arfmart, or other like plants, only 
there the fpring moves and curls up inwards, but here it 
moves outwards; every feed cafe ftands upon a little pe¬ 
dicle, a a a, fig. 439. being of a filver colour, and of a 
fpherical figure ; it is girded about with a ftrong tendon 
or fpring a, (whofe furface refembles a fine fcrew, of a 
golden colour, which breads the cafe, immediately upon
