4th—The heavy work of pruning and harvest can be done at different times so that they do not interfere with one another. In fact the pruning of the vine may precede that of the olive and the vintage comes when the olive begins to turn. Thus the consociate cultivation of the olive and vine will enable one to keep the same laboring force right through the year and avoid the constant shifting of hands which is so great a drawback.
5th—The olive and vine being so different in size, the tree only affects unfavorably the nearest vines.
6th—Being both potash plants they prosper in the same land and are benefitted by the same manure.
7th—If the consociation is temporary, the vines will gradually pass away by the time the olive, at thirty years, has reached its normal development, but will have in the meantime contributed largely to pay the expenses of the place if they have not entirely done so, and if the consociation is permanent a certain number of vines are up-rooted and a broad belt left to olives.
