The signs by which _good chocolate_ or cacao is known are these:--It should dissolve entirely in water, and be without sediment; it should be oily, and yet melt in the mouth; and if genuine, and carefully prepared, should deposit no grits or grounds. That made in the West Indies, and in some parts of Cuba, is dark; but that manufactured in Jamaica is of a bright brick colour, owing to the greater quantity of arnatto which is used in the preparation, and which, I think, gives it a richer and more agreeable flavor. In an economical point of view, chocolate is a very important article of diet, as it may be literally termed meat and drink; and were our half-starved artisans, over-wrought factory children, and ricketty millinery girls, induced to drink it instead of the innutritious beverage called "tea," its nutritive qualities would soon develop themselves in their improved looks and more robust constitution. The price, too, is in its favour, cacao being eight-pence per pound; while the cheapest black tea, such as even the Chinese beggar would despise, drank by milliners, washerwomen, and the poorer class in the metropolis, is three shillings a pound, or three hundred and fifty per cent, dearer, while it is decidedly injurious to health. The heads of the naval and military medical departments in England have been so impressed with the wholesomeness and superior nutriment of cocao, that they have judiciously directed that it shall be served out twice or thrice a week to regiments of the line, and daily to the seamen on board Her Majesty's ships, and this wise regulation has evinced its salutary effects in the improved health and condition of the men. Indeed, this has been most satisfactorily established in Jamaica among the troops; and the same may be asserted of the seamen in men of war on the coast.
