RESTORATIVES. The popularity of small salt fish -- anchovies, sardines, pilchards -- in Latin countries has much to do with heat, physical fatigue and need for restoration. These fish, even though desalted before serving, are by nature thirst-provoking; and thus induce the workman, parched by his labours, to imbibe copious draughts of water (or wine) and so restore the balance. These observations have significance in a working context round latitude 40.
NOTE: They are nice just to look at also.
