RIVETLESS STEEL

DOMINION FOSSIBILITES

ENGLISH EXPERT'S VISIT.

A recognised specialist in electricwelded steel construction in Europe and the United States of America, Major James Caldwell, J.P., M.lnst.C.E., of London, is,of the opinion that New Zealand is in a position to make extensive use of rivetless steel construction, thereby reducing costs of manufacture. Major Caldwell, who is accompanied by his son, Mr. Hugh Caldwell, sa'iled this morning by the Tofua for Suva, where h- will join the R.M.m..;. Aorangi on her next trip to Vancouver.

Major Caldwell is making his tour with the object of studying engineering conditions and future trading possibilities. He left England in October and has already visited South Africa, Rhodesia, East Africa, India, Burma, Java and Australia.

During hi<s stay in New Zealand, Major Caldwell wad particularly interested in the progress made in the development of rivctless steel throughout the Dominion. Apart from the completed works in the South Island and at Wellington, the undertaking now in progress at the Hamilton reservoir, he believes, .should assist in the standardisation of welded structures, which are erected from plates and steel sections assembled in situ, thereby saving the cost of transporting fabricated parts and a. reduction in weight of the materials used. When attached to the Admiralty during the war, Major Caldwell was responsible for the construction of the first seagoing steamer. Major Caldwell is a keen angler and he was delighted with the sport in New Zealand. "Your fishing i.s great," he paid, before the Tofua sailed this morning. He spent ten days fishing at the delta at faupo and three days at Whangaroa, where he landed a 2931b striped martin.
