Jerguson Gage & Valve Com- pany is one of the White Consoli- dated Industries, Inc., a widely diversified manufacturer of ma- chinery and equipment for indus- try and the consumer. forced for operation in ice, with 7,500 to 10,000-horsepower engines, and a crew of about 20 men. They would cost $6 million to $9 million apiece. A fleet of five could be built, manned, and operated for about the same cost as one me- dium-sized icebreaker.

Emphasizing the need for at least five of the smaller icebreak- ers, the admiral said that effective movement of freighters in early winter requires icebreaking in four lakes simultaneously, and occa- sionally at several places in each lake. This means a number of ice- breakers are necessary to do the job; one can only be in one place at a time. Also, with the wider beam of the new lake vessels, an icebreaker has to make two swaths to open the channel and have the maneuverability to "ease the turns" for the long vessels.

In addition to providing the needed support for the domestic shipping industry's extended navi- gation season goals, Admiral Trim- ble said a tug icebreaker of the same size would be capable of sup- porting the St. Lawrence Seaway's effort for a longer season for ocean- going shipping as well.

The icebreaker Mackinaw, built especially for lake service, still has many years of operation remaining and will be most helpful for heav- ier icebreaking assignments, such as in Lake Superior in the spring. 1492-1973

Icebreaking Tugs

Proposed To Keep

Lakes Shipping Open

Tugboats, stressed and powered for icebreaking, and costing about one-fifth as much as a conventional medium-sized icebreaker, should be sought for keeping shipping routes open for late winter sailings on the Great Lakes, Vice Adm.

Paul E. Trimble, president of Lake

Carriers' Association, told a meet- ing of shipping representatives and the Coast Guard at a recent meet- ing in Cleveland, Ohio. Assessing the icebreaking requirement as a matter of numbers more than of size, the admiral said: "A fleet of five 'general duty' icebreaking tugs would give the lakes much more icebreaking for the buck than one of the larger-sized icebreakers could."

Experience in winter operations, aimed toward extending the lake navigation season beyond mid-De- cember, has shown that smaller but high-powered icebreaking ves- sels can do much of the work needed to keep shipping moving through lake ice fields. This in- dicated that a much more cost- effective approaeh to icebreaking is several small "general duty" ice- breakers, rather than more large ones, Admiral Trimble said. The smaller vessels could be a more or less standard seagoing tug design 160 to 180 feet in length, rein-

In 1492 an Italian explorer, Christopher

Columbus, a unique man who relished a challenge, sailed on a voyage to prove his theory that the world was a sphere.

His ship, The Santa Maria, was the largest of the three ships he commanded when he discovered a new world. . 480 years later, Pittsburgh-Des Moines

Steel Company, a unique American company that also has the reputation of meeting challenges, is building spherical tanks for ships which will carry LNG to the new world Columbus discovered.

Columbus would have liked PDM ... especially if he knew that the spheres PDM is building WOULD ENCOMPASS HIS

WHOLE FLAGSHIP, THE SANTA

MARIA, including hull, masts, sails, bow- ocean to float her! cnou
