A female plant cultivated by itself in a garden produced 

 small unproductive seeds. Linn. Nectaries 5. Stamens 6, 8, or 



lerably flexible; not easily splintering; and therefore is preferred before 

 all other timber for building ships of war. It is well adapted to almost 

 every purpose of the carpenter ; but an attempt to enumerate all the uses 

 of this well known wood, would be equally superfluous and difficult.— 

 Oak saw-dust is the principal indigenous vegetable used in dying fustian. 

 All the varieties of drabs, and different shades of brown, are made with 

 Oak saw-dust, variously managed and compounded. — The balls, or Oak- 

 apples, are likewise used in dying, as a substitute for galls. The black got 

 from them, by the addition of copperas, is more beautiful than that from 

 Sails, but not so durable. — The bark is universally used to tan leather. 

 Its astringent properties may be turned to good account in many medical 

 indications. An infusion of it, with a small quantity of copperas, is used 

 by the common people to dye woollen of a purplish blue: the colour, 

 though not very bright, is durable. The balls, or galls upon the leaves, 

 are occasioned by a small insect with four wings, called Cy?iips quern 'filth 

 which deposits an egg in the substance of the leaf, by making a small per- 

 foration on the under surface. The ball presently begins to grow : and 

 the egg in the centre of it changes to a worm ; this worm again changes to 

 a nymph, and the nymph to the flying insect with four wings. — Horses, 

 cows, sheep, and goats eat the leaves. Swine and deer fatten on the acorns.

 —An Oak tree in the parish of Little Shelsley. Worcestershire, measured 

 in circumference about z yards from the ground 12 feet 4 inches, and close 

 to the ground nearly 48 feet. Mr. Hollefear. — In one growing in I7°4» 

 In Broumfield Wood, near Ludlow, Shropshire, the trunk measured 65 

 teet in girth, and 23 in length, and which, allowing go square feet for the 

 larger branches, contained 1455 feet of timber. Liohtfoot.— The girth of 

 The Green Dale Oak, near Welbeck, at n feet from the ground, was 3 8 

 feet; and one growing at Covvthorpe, near Wetherby, Yorkshire, mea- 

 sured 48 feet in circumference at 3 feet from the ground, and 78 feet close 

 to the ground. Hunt, cruel, with a figure of the former at ii. p. 200, and 

 of the latter at p. 197. In. the year 1757, an Oak in Earl Powis's Park, 

 near Ludlow, measured 16 feet 3 inches at 5 feet from the ground, and 



its trunk rose full to feet quite straight and clear of branches. Bath Stf. u
