Extra Weather Telegrams. The following stations send extra weather telegrams at half rates during typhoons, on receipt of certain code words from Hongkong:-Amoy, Canton, Macao, Phulien, Sharp Peak, and Taihoku. The Director of the Philippines Weather Bureau also sends extra telegrams, at his discretion, from Aparri or some other station nearer the typhoon centre. The extra 9 p.m. telegram, from Swatow, kindly sanctioned by the Chinese Telegraph Administration during the typhoon season, was seldom received.
Wireless Weather Telegrams. There has been but a poor response to the Marconi Company's circular and the Observatory Notice to Mariners respecting wireless weather telegrams referred to in the 1919 report. Less than 10% of the ships within range sent weather telegrams to the Observatory during the year.
The following table gives the monthly number of ships, of different nationalities, from which wireless meteorological messages have been received, and the number of messages received, (each arrival and departure is counted separately).
