Description
A diagram showing how to insert a hollow pipe diagonally near the lower joint of the branch of a birch tree (ab indicates the upright trunk of the tree) in order to collect the sap. From an extract of a letter (EL/B1/52/007) by John Beale, who also had an interest in orchards and cider-making.

Transcription
Ab is the upright body of the Birch, c is an arm or branch growing out of its side: di is the end of a faucet or other hollow pipe inserted into the orifice of an Augur-hole made through an arm or body of the tree from c to f; the larger this is made the more plenty of sap is expected: the little Lip at e, bending down under the arm, is intended to be so much barked, pilled [=peeled] off from the place, where the Augur enters, as may serve to direct the sap into the Bottle, to be tied up to the arm, so as it may fall directly into the bottle.
