The extent of these “Métairies” varies according to the number of the family of the métayer, and the nature of the soil, from 65 journaux (52 statute acres) to 30 journaux (24 acres), for the métayer generally endeavours to cultivate the land he holds, without the help of hired servants or labourers. Average land producing rye ought to be worth to the métayer 7 francs (5 s. 7 d.) per journaux (four-fifths of an acre); that producing wheat 25 francs (1 l.) per acre. The only land farmed is meadow land, situated in the lower part of Médoc, called “Bas Médoc,” and a part of the district of Blaye, which is let, at an average, 80 francs (3 l. 4 s.) the journaux (four-fifths of an acre).[…]The best wheat land gives 10 hectolitres per journaux, that is, three quarters and four-sevenths per four-fifths of an acre. The worst three hectolitres (1 quarter per four-fifths of an acre,) or one journal. Rye gives six hectolitres per journaux (2 quarters per four-fifths of an acre). Oats sometimes 25 hectolitres per journaux (8 quarters and 13-14ths, per four-fifths of an acre).
