The nights on which various mails go out are extra busy ones, especially Friday evening, when the Indian, Chinese, and Australian mails are sent. The reduction of the postage has made an enormous difference in the contents of the mail-bags to these parts of the world. It may be interesting here to note how the mails are dealt with at Brindisi. Van after van conveys the mail-bags from the train to the ship, where two gangways are put off from the shore to the ship's side. Lascars run up one and down the other with the bags. Each lascar has a smooth flat stick like a ruler, and as he deposits his mail-bag on a long bench over the hold, he gives up his stick to a man standing by. When five lascars have arrived, the sticks go into one compartment of a small wooden box; and when the box is full--that is, when a hundred have been put in--the box is carried off and another brought forward. Three hundred and ninety-two bags is a good average, and they take just under forty minutes to put on board. The French and Italian mails are included in these; but no other European mails go by the Peninsular and Oriental Company. At Aden, two sorters come on board and spend their days in some postal cabins sorting the mails for the different parts of India, &c. The bags in which these mails are enclosed are only used once. They are made in one of our convict prisons, and fresh ones are distributed each week both outward and homeward. Turning from the General Post-office South, which is now exclusively utilised for letters and papers, we proceed to the General Post-office North, which is devoted solely to the telegraph department. The Savings-bank department was originally in the same building as the telegraph; but owing to the rapid increase in both departments, the Savings-bank has been removed to Queen Victoria Street. Coldbath-Fields Prison was converted into a home for the Parcel Post. Some three thousand male and female clerks are employed in the telegraph department alone. The top floor of the building is devoted to the metropolitan districts. A telegram sent from one suburb of London to another is bound to pass through St Martin's-le-Grand; it cannot be sent direct. The second floor deals with the provinces. The pneumatic tube is now used a great deal; and by means of it some fifty telegrams can be sent on at once, and not singly, as would be the case if the telegraphic instrument was the only instrument in use. The tube is mostly used at the branch offices.
