G.T. Western Ry. double-tracking.—In connection with double-tracking of the line from Port Huron to Chicago, the contractors have struck a "sinkhole" near Haslett's Park, Mich., 106.29 miles from Port Huron. Eighteen thousand yards of gravel have been dumped into the hole up to the end of Aug., and it was expected that the steam shovel would be employed in filling the hole until Nov.
