J. Bruce Ismay, one of the owners of the White Star Line of steamships, and Hon. W. J. Pirrie of the shipbuilding firm of Harland & Wolff of Belfast, the builders of the White Star steamers, who recently came over on the Celtic to get an idea as to how that vessel worked, sailed for home on the Oceanic yesterday morning. As to whether the line would have built a vessel larger than the Celtic, Mr. Ismay said, depended on the channel improvements here. He ridiculed the report that the White Star Line had been purchased by J. Pierpont Morgan. A statement that the company contemplated the establishment of a line to the moon, he said, would be about as true as the reported sale.
