ALTHOUGH the angle is the section most commonly used as a strut, we have had some doubt
in the past as to the actual strength of steel angle struts when connected in the manner commonly employed in roof-truss, trestle and other framework. In Bulletin No. 218, issued by the United States Bureau of Standards, results are given of an investigation into the subject made by Messrs. A. H. Stang and L. R. Strickenberg.
AS we have previously announced the Government of New South Wales has accepted the tender of Messrs. Dorman, Long & Co., Ltd., of Middlesbrough for the construction of the North Shore Bridge over Sydney Harbour.

It is claimed for the Standard Concrete Machine that it is designed to give unrestricted scope in the manufacture of concrete products. An idea of the range covered by this machine, some of the products of which we illustrate, may be gathered
from the fact that the largest casting which can be produced has a length of 6 ft. and a width of 3 ft., and any thickness within the limit of the maximum weight of the product, which is two tons. Also a number of products can be made at one operation of the machine; for example, three or four lintols, four or more cills, two, three or four kerbs, and six or more channels. The product can be moulded on any or all of its
four sides; and it can be made solid or hollow, ornamented or plain.
