LIFT BRIDGE OVER THE MURRAY AT SWAN HILL. XCIX. 
of the timber, with the exception of a few piles was obtained from 
the northern rivers of New South Wales, forwarded to Melbourne 
by sea, a distance of about 726 miles, thence to site by rail a 
distance of 214 miles, or a total carriage of 949 miles, the planed 
and framed timber in truss work being erected in situ at 4/- per 
cubic foot, which gives a clear idea of the economical character 
of this design of truss. Mr. D. W. Armstrong was the Resident 
Engineer in charge of the erection of the structure, he having 
previously superintended the erection of the lift bridge at 
Mulwala. 
In conclusion the author desires to acknowledge his indebtedness 
to Mr. Darley, m. mst. c.z., Engineer-in-Chief for Public Works, 
(under whom the Swan Hill Bridge was completed) for the courtesy 
extended in lending photographs and supplying plans to illustrate 
the several bridges referred to in the paper, and to mention the 
assistance of Messrs. Dare and Edgell, Assoc. Ms. Inst. C.E.; who, 
under the author’s direction were engaged on the more important 
detail work connected with the structure.
