The alterations to the telegraph and telephone lines had been carried out by the Posts and Telegraphs Department in accordance with their ideas of the requirements to minimize interference which they feared from the 33-kilovolt lines. I n addition, theDepartmenthad called for transposition of the 33-kilovolt lines, which had been carried out by the Railway Company.Energy was charged for on a two-part tariff, according to maximum demand (half-hour monthly) and consumption, with provision foradjustment withvariations in the price of fuel...

192 DISOUSSION ON IRRIGATION M INbIA. [Minutes Of Mr. Preston. furnished with iron gates and gearing for enabling the supply to be regulated in the channel. Mr. Fitzmaurice had misunderstood the duty anticipated from the canal, which was never likely to reach the 3,000,000 acres mentioned by him. The canal had been done designedto irrigate 1,100,000 annually,andhadalready 2,000,000; but it wasunlikely it would ever exceed 2,500,000 acres. Mr. Whiting's suggestion that every cultivator should use the water simultaneously was impracticable; it was correct for the distributionof the waterfrom the Government distributaries to the village watercourses, and was the practice actually in vogue ; but the distribution of the water to the fields from the villagc watercourses, which wasdone in the manner described in thePaper, could not bedone as Mr...

242 DISOUSSION ON GOVERNMENT OFFICES : Discussion The Authors introduced the Paper with the aid of a series of lantern slides, illustrating the early history of the site and showing details of the progress of the work. Mr R. B. M. Potter, referring to the element of risk in the moving of the crypt, observed that, as soon as his firm had obtained the contract for the work, he had been able to report that it would probably be one of the safest jobs ever to be undertaken by them, but that iwt ould probably be neither a quick nor an economical job...

!FHE BTRENGTH OF CEMENT. 307 Mr. J. GRANT at this stage he said, would simply point out the form of moulds used in the experiments. No. 1, Table 1, was the first form, and was used previous to 1865. It would be perceived that the angles were very sharp, which was the cause of irregular fractures. After some esperience the original form of mould was. modified, as shown in No. 2, Table 1 , in which the angles were rounded off, and which hadbeen i n use for several gears...

168 DOCKS -4ND WAHEHOUSES MARSEILLES. AT Mr. VIGNOLES he was at Marseilles about the year 1846, said when some of these works were being commenced ; and he afterwards crossed over to Algiers, where the concrete blocks were used to a large extent, andhe obtained the best information he could as to their dimensions. Various statements had been made with regard to the wearing away of such blocks; and it had been asserted by some Engineers, that there was a chemical property in the water of the Mediterranean which decomposed the concrete blocks...

42 DISCUSSION ON FLOATING DOCKS. [Minutes of Discussion. The President. The PRESIDENT, in moving a vote of thanks to the Author for his veryinterestingPaper, remarked thatthe subjectwas of considerable importance at thepresent time, for events happening in the Far East would doubtless give great impetus to the construction of floating docks. The Author. The AUTHOR exhibited a numberof lantern-slides illustrating the construction and use of floating docks. Mr. Harding. Mr. W. J. HARDING thought the Paper pointed the moral that the docks of one generation were not suited to the requirements of thenext...

Proceedings.] CIJXENT OF IANUFACTURE, 73 Discussion. The PRESIDENT considered thattheInstitutionwasgreatly The President. indebtedtotheAuthors for theirusefulandimportantPaper. Most engineershad more to do withthe use of cement than with its manufacture, but it was interesting to know that such great strides in the method of manufacture were being made, and he hoped` that in this country, as in America, engineers would now have the benefit of getting a cement of superior quality at less cost thanhad been hithertothe case. He wassurethe members would agree with him in according to Messrs...

Proceedings.] DISCUSSION ON DEPOSITS IN PIPES. 43 Discussion. The PRESIDENT, inmoving avote of thanks to the Authors, The President. remarked that the Papers dealt with questions of great practical importance, and he was assured by friends who were experienced i n such matters that they were likely to be of considerable value to future engineering practice in water-supply. BROWN placed on the table a typical specimen Prof. B ~ Professor CAMPBELL of what he called "limpets," andsome called "barnacles," but which were really incrustations of iron...

260 DISCUSSION ON THE ELECTRIFICATION OF THE [Minutes of Discussion. The Author. Sir Clement Hindley. The AUTHOR, exhibiting a number of lantern slides, remarked in that the mostinteresting feature of the overhead equipment was perhaps the form of mast used, which consisted of a G-inch by 6-inch joist, slit in the web, and expanded to give the necessary greater width at the base. On to these masts all t'he t,op equipment was clipped, and the wholewas capable of being adjusted in position. That arrangement obviated drilling, which had objections, and assisted greatly in the erection, besides reducing the cost...
