The berries are much richer in volatile oil than the leaves, but on account of the height of the trees, the gathering of the berries is connected with so many difficulties and the harvest so scanty, that the manufacturers prefer to mix leaves and berries in a certain proportion. The following directions for preparing bay rum are given in Schimmel & Co.'s reports:-- I. Alcohol of 95 per cent. 4 lbs., water 4 lbs., bay oil 5½ drachms, pimento oil 2¼ drachms, clove oil 10 drops. Mix, let stand for several days and filter. II. Alcohol of 95 per cent. 4 lbs., bay oil 15 drachms. Mix, let stand for 2 weeks, and then add 8 lbs. of best Jamaica rum. This bay rum is said to be equal to the imported. Another receipt for bay rum is as follows:-- III. Alcohol of 95 per cent. 1 quart, rectified spirit of 60 per cent. 14 quarts, bay oil 1 oz., loaf sugar 4 ozs. Beat up the sugar with the oil and add the alcohol; then the spirit, and finally filter. Mierzinski gives the following formulæ for bay rum:-- IV. Alcohol 8 ozs., oil of bay 40 drops, oil of mace 1 grain, oil of orange 20 drops, Jamaica rum 1 oz., water enough to make 16 ozs. Digest 2 or 3 weeks, and filter through magnesia.
