which is frequently almost insupportable to a European. "The best houses are all facing the sea, and chiefly to the north of the sea gate. The British factory is a large and lofty building, but has most of the inconveniences of an Arab house. "The town of Mocha is surrounded by a wall, which towards the sea is not above sixteen feet high, though on the land side it may, in some places, be thirty.

"Mocha, according to some learned natives, was not in existence four hundred years ago; from which period we know nothing of it, till the discoveries and conquests of the Portuguese in India opened the Red Sea to the natives of Europe." Mrs. Lushington, in her interesting _Journey from Calcutta to Europe_, says, "the coffee-bean is cultivated in the interior, and is thence brought to Mocha for exportation. The Arabs themselves use the husks, which make but an inferior infusion. Every lady who pays a visit, carries a small bag of coffee with her, which enables her 'to enjoy society without putting her friends to expense.'" Mocha coffee is in smaller berries than other kinds, and its flavour is extremely fine. Hundreds of pages have been written on the origin and introduction of coffee as a beverage. In the _Coffee-drinker's Manual_, translated from the French, we find it dated at the middle of the seventeenth century, and in that quarter of Arabia wherein Mocha is situated. * * * * * ORIGIN OF THE HOUSE OF COMMONS.
