May 30 [1790]. John Carpenter brings home from the Plashet at Rotherfield some old chest-nut trees which are very long. In several places the wood-peckers had begun to bore them. The timber & bark of these trees are so very like oak, as might easily deceive an indifferent observer, but the wood is very shakey, & towards the heart cup-shakey, so that the inward parts are of no use. They were bought for the purpose of cooperage, but must make but ordinary barrels, buckets, &c. Chestnut sells for half the price of oak; but has some times been sent into the King's docks, & passed off instead of oak.
