Subject：Ship Accident off West Coast of Chang Jiang，No Casualties.
Yesterday evening two boats collided in thick fog in Chang Jiang not far from Wu Han.One was a cargo ship carrying lumber，apparently on its way to Chang Jiang.The other was a National ferry on its regular run from Jiu Jiang to Wu Han.
However，because of the weather conditions，the captains did not realize the danger until a few seconds before the collision took place.Consequently，there was no time for them to prevent the accident.
Fortunately，there were no casualties among the crews or passengers，but both ships suffered badly damages.
A spokesman for the port authorities said that a committee would be set up to determine the cause of the collision.
