ABSTRACT
There is seldom more than one rate in a year except in 1810-20 and then never more than three.
Windsor prices, from 1821, are higher than those for Carlton House and are omitted.
In the period when the three kinds are on different levels, Lucca olives, the dearest, have been used in the main table ; the others are given below. When no purchases are recorded, contract rates are used.
