... of Discussion. Pmfeeaor Professor ROYAL-DAWSOinNtroduced and supplemented his h~e -Damon* Paper by showing a series of lantern-slidesillustrating the use of plotters for realigning a given curve, and analysing an existing re-alignment for comparative purposes.

.... The Western Ghats are geologically of great age, and mainly consist of charnockite. Throughout the range this has disintegrated under vegetation into a soft red or white material, showing in places the stratifications of the original rock, and containing a t varying depths boulders of hard, fresh, blue...

... state, possibly elastic, had been missed, in that the curves should have emanated from the origin, their equations being of the form + dp = a c d x , and not merely p = Having established the fact of an elastic limit in direct shear, he proceeded to correlate the experimentswith pressure-penetration...

.... SirFrederick had originally proposed to put the dry dock nearlyparallel to the existing entrance-lock, but he had changed that plan and put it at the eastern end of the main dock, near to the existing dry docks. That was a very good decision, as itenabled all the ship-refitting and all the pumping arrangements...

... paint would stand if applied on top of the original coat of red-lead paint, as stated on p. 361. In his experience there was no objection t o the use of bituminous paint over red-lead paint, but the decision had been queried at the time, and it would be of interest t o have the views of other engineers...

... of these values is lower than the discharge-capacity of the dam. A special investigation wasmade to ascertain if the discharge-capacity of the dam could be increased from the original figure of 470,000 to 600,000 cusecs ; it waa found that the cost of the necessary arrangements wouldbe very slight...

..., and the parapet formed a stop for the big blocks. Incidentally, it gave asmooth walk out to the boIlards. Originally it was intended to have a pell-mell breakwater, butthe stone on thetop was the weakest spot, and might easily have been washed over inside the harbour. That top stone would have had only its own...

... the reasons why the true extent of the work was not disclosed by the original investigations ? Although the depth below ordinary ground-water-level to which work had t o be carriedwasvery considerable, the total quantity of pumping was not excessive ; could not the trench have been excavated with the aid...

... theupstream face of thedam " gunited," a procedure not contemplated in the original scheme. He would be glad to hear Mr. Hellstrom's remarks on that point; did not Mr. Hellstrom think that a slightly thicker slab with lighter reinforcement would have been more economical for a tropical job ? Thesubject...

... was originally anticipated, and so, in place of the pitched slopes to the excavation originally proposed, retaining-walls to hold the hillside had to be built. In places quite large areas of shale rock were exposed, but it was found that during the winter weathering occurred, and it was not considered desirable...

Subsequentexcavation showed that the actual rock-surface was a t a slightly higher level. In the same year, Mr.McCulloughwas taken seriously ill. His illness...

Each type of crusher is considered from the following aspects :(U) Its origin. (b) Intermediate stages in its development. (c) Modem examples. (d) Its special use. (e...

..., and to endeavour to correlate those physical properties with the behaviour of stones in use. The testing of the mechanical properties of road-stone, as a means of determining its suitability for use, was carried out on more or less standard lines in America, on the Continent, and also in England, and the original...
