636 FEDERAL REPORTER. �starboard. On passing they went so near and at such speed as to create a swelly which broke over the scow and caused her to roU so that she dumped ail the chalk into the river. Thers'was room for the steamers to have passed at a greater distance, and they might have reduced their speed, in either of which cases the swell would not have been dangerous. �In addition to these facts the libellant claima to have shown that the hatch covers on the scow were insecurely fastened, and by reason thereof when the swell struck the scow the covers were washed off the hatohes, and so a quantity of water was allowed to go into the hold, which by its presence in- creased the rolling of the scow and was the immediate cause of the loss of the chalk.
