Beginning with April 25 all radio weather reports from ships were broadcast at 8 a.m. and 4 p.m., but as the Manila Authorities were unable to pick up the messages the practice was discontinued on 11th October.
The question of regular observations from ships by wireless telegraphy was taken up vigorously by the Chamber of Commerce, with the gratifying result indicated by the above table.
There is still room for improvement however. A Notice to Mariners giving particulars of what information is required is handed to masters of vessels by the Harbour Department. Copies are also sent to the shipping companies for distribution to their Captains. Supplies are also sent to the Master Attendant, Singapore, who has kindly consented to furnish copies to north-bound ships.
An attempt is being made to standardize the form in which weather telegrams are sent out from ships. It is hoped that this will make the work less onerous and also diminish the risk of error.
