Almost all Indian correspondence is carried on by means of post cards. It is the only country, perhaps, in which the post card may be said to be a real success. In India it exactly supplied a want. The card is cheap (it only costs 1/4d.), and it is complete in itself. Stamps and envelopes have to be wetted. The gum may have been made of the hoofs or bones of the cow, and the thought of possible defilement of caste comes in. The post card has no drawback. Its publicity, which makes English people dislike it, is not considered a disadvantage by the Indian. He reads other people's letters as a matter of course, and expects other people to read his. I have often seen a postman seated by the street side sorting out his post cards, surrounded by an interested little crowd. He and they are reading as many of the post cards as there is time for, and no one appears conscious of irregularity in the proceeding. A post-office inspector who was travelling in the train with me told me that they have great difficulty in checking robberies committed by the Indian train-sorters, because effective supervision is impossible. In the interval between station and station, which in some of the mail trains is often an hour or two, the sorters know that they are secure from interruption. They get skilled in detecting by the feel the presence of a bank-note within an envelope. In a country where paper currency is largely in vogue people often send money by post in the form of notes in unregistered letters, trusting to the thin note not being observed. Many such notes get stolen by the train-sorters. Even sending half notes is not always a security, if the remitter does not take the precaution of waiting to hear of the safe arrival of the first half. The dishonest sorter having secured the first half, and having observed the post-mark and hand-writing, will be on the look-out for the other half, which he knows is likely to come along the same route in a day or so. The only chance of getting hold of the thief is by setting a trap for him in the shape of a marked note or coin. But the Indian thief often suspects and avoids the trap. Inspectors board the train at unexpected stations, and travel for a while with the sorters, and look into their affairs; but the sorters are generally ready for them, and no sign of irregularity is visible. Nevertheless a certain percentage of thefts are brought to light, and the delinquents sent to prison. Insurance of articles sent by post is a great safeguard, as is shown by the fact that in one year recently the total insured value of articles posted amounted to nearly L17,000,000, whereas the sum paid in compensation was only about L500.
