TRANSIT TUBE SETTLES Engineer Hopes to Restore It With Fiozen Mud. NEW YORK, Jan. 1 A small section of the ast Iron tube f the rapid transit tran-sit tunnel to Brooklyn is twenty inches : below the adjoining section on the New York ld' pays a morning paper. The section whbh has settled consists of I but one or two of the cast Iron rings one of which is only twenty Inches ; lotig. but the- mishap will make it Impossible Im-possible to run l rains of standard height through the tunnel unless the rings can be raised, and the slip has put thf construction firm which Is building the tunnpl up against the most : difficult engineering problem It has encountered en-countered After failing to devise a plan for readjusting the sunken parts ' of the tube, the company engaged a me-Cbahii me-Cbahii al engineer to remedy the difficulty diffi-culty and h is accepted a noel plan of his Invention His plan is thus des rlbed by another engineer engaged in the work: Use? Frozen Mud "It has been shown," said the latter, "that frozen mud has the stability of concrete. The engineer proposes roughly rough-ly to freeze the mud four feel above the sunken tube, remove the roof of the tube, cut ofi enough of the frozen mud to make the bore of the right dimensions dimen-sions :ind then restore the rings to their proper position The plan, of course. Includes the use of ammonia In freezing, freez-ing, but Just how it was to be applied I do not know. T understand that no , one doubts the success of the plan and i I am satisfied that it win furnish an I Important contribution to engineering know ledge,"
