six
o'clock a.m
-LSB- See note 1 . -RSB- A much more serious accident occurred at another time , however , which resulted in the death of one of the seamen belonging to the _ Smeaton _ . It happened thus . The _ Smeaton _ had been sent from Arbroath with a cargo of stones one morning , and reached the rock about half-past six o'clock a.m. . The mate and one of the men , James Scott , a youth of eighteen years of age , got into the sloop 's boat to make fast the hawser to the floating buoy of her moorings . The tides at the time were very strong , and the mooring-chain when sweeping the ground had caught hold of a rock or piece of wreck , by which the chain was so shortened , that when the tide flowed the buoy got almost under water , and little more than the ring appeared at the surface . When the mate and Scott were in the act of making the hawser fast to the ring , the chain got suddenly disentangled at the bottom , and the large buoy , measuring about seven feet in length by three in diameter in the middle , vaulted upwards with such force that it upset the boat , which instantly filled with water .
