ICE INFORMATION.
Ice telegrams, giving information of the ice conditions at Taku, Chinwangtao, and— as far as can be ascertained-in the Gulf, will be sent daily from Taku and Chinwangtao and will be posted at the Harbour Offices at Chefoo, Taku, and Tientsin. They will also be sent to Dairen.
Masters of steamers are requested to co-operate in this matter by reporting the ice conditions met with to the Harbour Masters at Tientsin, Chinwangtao, and Chefoo im- mediately on arriving at one of these ports. Such reports will be posted.
To facilitate the making of these reports a special book of forms will be supplied on application to any of the Harbour Offices mentioned.
Masters of Steamers are further requested to co-operate by making it a routine practice to signal to passing steamers the ice conditions experienced. The following special signals should be used for the purpose.
