LX. With respect to preserving olives, Cato advises that table olives, both the round and the bitter berried kinds, keep best in brine both when they are dry and when they are green, but if they are bruised it is well to put them in mastich oil. Round olives will retain their black colour if they are packed in salt for five days, and then, the salt having been brushed away, are exposed for two days in the sun: or they may be preserved in must boiled down to one-third, without the use of salt. _Of storing amurca_ LXI. Experienced farmers do well to save their amurca as they do their oil and their wine. The method of preserving it is this: immediately after the oil has been pressed out, draw off the amurca and boil it down to one-third and, when it has cooled, store it in vats. There are other methods also, as that in which must is mingled with the amurca. 6° CONSUMING TIME LXII. Since no one stores his crops except to bring them out again, it remains to make a few observations upon the sixth and last operation in our round of agriculture. Crops which have been stored are brought out either to care for them, to consume them or to sell them, and as all crops are not alike there are different times for caring for them and for consuming them. _Of cleaning grain_ LXIII. Grain is taken out of store to be cleaned, when the weevil begins to damage it. When this is apparent the grain should be laid out in the sun and bowls of water placed nearby and the weevil will swarm on this water and drown themselves. Those who store their grain in the pits which are called silos should not attempt to bring out the grain for some time after the silo has been opened because there is danger of suffocation in entering a recently opened silo. The corn which, during the harvest time, you stored in the ear and which you contemplate using for food, should be brought out during the winter to be crushed and ground in the grist mill. _Of condensing amurca_ LXIV. When it flows from the oil mill, amurca is a watery fluid full of dregs. It is the custom to store it in this state in earthen jars and fifteen days later to skim off the scum from the top and transfer this to other jars, an operation which is repeated at regular intervals twelve times during the following six months, taking care that the last skimming is done on the wane of the moon. Then it is boiled in a copper kettle over a slow fire until it is reduced two-thirds, when it may be drawn off for use. _Of racking wine_
