Practically every case of stranding could have been prevented by the use of a first-class sounding machine. Boats using UPSON'S IMPROVED SOUNDING MACHINE a wan PATENT DEPTH GAUGE are insured against delay, as soundings can easily be taken with vessel running at full speed. Printed matter, giving full information, and showing what is thought of the machine by those who are using it will be sent on request. THE UPSON-WALTON CO. CLEVELAND \\ePS BROKEN STERNPOSTS AND <=. RUDDER FRAMES WELDED IN. PLACE '?/ the British Corporation for the Survey and Regis- try of Shipping. The Thermit Process enables you to weld brok- en sternposts, rudder frames, shafts, etc., without removing them from the vessel. All of our appli- ances are portable and may be brought to the job. No outside power is required with the exception of a small supply of compressed air. * Thermit is a mixture of finely divided aluminum and iron oxide which burns up and produces liquid steel at a temperature of 5,4009F. Thisis poured into a mould surrounding the broken sections and the intense heat of the Thermit steel causes it to dissolve the metal with which it comes in contact, amalgamating with it to form a homogeneous mass when cool. Pamphlet No. 20-E tells all about it. Write for a copy and for "Reactions", the Thermit Quarterly.
