On Saturday morning, about eleven o'clock, three brothers, named GOLDING of ARLINGHAM, were returning up the Severn from Bulo, in a small low boat, belong to Mr Markey of ARLINGHAM, and laden with 4 tons of coal, bound from home, when, from some cause - supposed to be over-loading - she capsized, and three men being precipitated into the water.
The elder brother proved a good swimmer, and he, with great presence of mine, immediately secured the oars belong to the boat, and threw them to his next brother, telling him to support himself until assistance arrived.
He obeyed, and was thus supported until picked up.
The deceased, William GOLDING, who was only thirteen years of age, struggled very hard to save himself, and for a short time buoyed himself up by putting his arms round his elder brother's neck, but the latter was unable to swim with this encumberance, was obliged to cast the poor boy off, and he sank.
The Newnham ferry boat went to the assistance, and picked up the other two. The body of the drowned lad was recovered in the evening, and taken to the boy's home, and the boat and part of the coal were afterwards dug out of the sand.
