There are other objections stated, and the result of the report is that the admiralty has countermanded all orders for Belleville boilers except in the case of ships that are at such an advanced stage of construction that a change of steam generators would mean a very serious delay. This alteration of plan will involve the modi- fication of the specifications of quite a number of the government con- tracts already placed with private builders. The committee, however, while condemning the Belleville boiler do not specifically recommend the adoption of any other type in its place. Their investigation is not yet completed, and they want a thorough test to be made with the Babcock & ,Wilcox and the Niclausse boilers, which are now being fitted on a couple of cruisers and sloops. They also ask that the cylindrical boilers be taken out of a couple of elderly cruisers and Dur and Yarrow boilers be fitted in their place for a year’s practical trial of these types. The committee are strictly of the opinion that “for naval purposes and from the military point of view,” the water tube boiler is preferable to the ed =| = ree was B # NUMBER OF ORDERS FOR NEW SHIPS NOT ENCOURAGING—REGULAR LETTER DEALINGS WITH OPERATIONS IN THE SCOTCH YARDS?" °°" 7" © eA [Special correspondence to the Mariné!
