After 12 to 15 years the heads become "tired," and should be grubbed up. The first year's crop, known as the "maiden" crop, is of small value but should be cut and the ensuing years of maturity will yield crops of about 130 bolts, green, per acre, worth £9, 15s.
If whitened, the loss in bulk and in rejection being two-thirds, this would produce about 44 bolts, which at £30 per load of 80 bolts, the appreciated market value of 1907, would be worth £16, ios.

A structure is composed, of pieces,such as the stones of a building in masonry, the beams of a timber frame-work, the bars, plates and bolts of an iron bridge.
Those pieces are connected at theii joints or surfaces of mutual contact, either by simple pressure and friction (as in masonry with moist mortar or without mortar), by pressure and adhesion (as in masonry with cement or with hardened mortar, and timber with glue), or by the resistance of fastenings of different kinds, whether made by means of the form of the joint (as dovetails, notches, mortices and tenons) or by separate fastening pieces (as trenails, pins, spikes, nails, holdfasts, screws, bolts, rivets, hoops, straps and sockets.
If the joint be provided either with projections and recesses, such as murtises and tenons, or with fastenings, such as pins or bolts, so as to resist displacement by sliding, the question of the utmost amount of the tangential resistance CQ which it is capable of exerting depends on the strength of such projections, recesses, or fastenings; and belongs to the subject of strength, and not to that of stability.
