The principal festival, and the one most religiously kept of all the holidays among the true believers--as the followers of Mahomet style themselves--is that of the Moharum, which lasts ten days, commencing from the appearance of the new moon, in the month of November, during which time handsome temples and mosques are constructed of bamboo and paper, and embellished with glass, paint and gilding. On the last day they are carried in grand procession through the public thoroughfares, proceeded by a band of music and accompanied by an immense concourse of spectators. Many of the faithful prostrate themselves before these Taboots, and in many instances rolling over and over in the muddy streets for a considerable distance, being generally well primed with bang or opium. There are occasional disturbances between the fanatics of the different castes, for many of these work themselves up to a pitch of frenzy by the use of narcotics and other stimulants, but the Government always take steps to prevent any serious outbreak, by having the troops posted in different parts of the town, ready to turn out at a moment's notice, and a strong body of police mounted and on foot accompany the procession to enforce order. At sunset they reach the river, and the day's proceedings terminate by the Taboots being thrown into the water, amid the shouts, gesticulation and vociferations of the now thoroughly excited populace. The Dewally Festival is equally recognized by natives of all castes and denominations as a sort of New Year's Day. Accounts for the past year are closed, and new books are opened. The dirt and rubbish of the past twelvemonth is removed, the houses thoroughly cleansed and at night the city or town is illuminated with lamps, Chinese lanterns, and other descriptions of lights, and the houses thrown open for general hospitality. The Hooley, the most revolting of all Hindoo Festivals, draws together an immense concourse of people. Large fires are made on the sides of the public streets and liquid dye stuffs, with every description of filth is thrown by the Hindoos on each other, and should any unfortunate Hindoo woman show herself in the street on these occasions, she is assaulted with language of the most obscene and disgusting nature. These festivals have of late years been curtailed by the Government, and now seldom last more than two days--that is, in large cities containing European communities--but in native towns it is still of many days duration. Accounts of these and other native ceremonies, together with the horrors of the black hole, experienced by Europeans, nearly one hundred years since at the suggestion of the native princes, had been related to Edith by her Moonshee Ayah, but their dominion, or power for good or evil, has now passed away, and Calcutta of the present day is one of the pleasantest and finest cities to the European to be found throughout our Indian possessions.
