    Iract between the Government and the Peninsular and Orien- tal Company, the Company are bound to perlorm the voyage from Suez to Bombay in 312 hours. The distance being 2972 miles, which gives an average speed of 9 1/2 knots an hour. Ifit wcre proposed to increasethat speed to 11 knots au hour, what should you consider to be the proper équivalent to be paid to the Company in considération of the extra speed thus given by them to the public? — That would entail a consumption of 7800 tons of coals, if the voyages were perfor- med weekly, and a cost of about 27 000 1. in money. I take it in this way : 11 knots would require 60 tons of coal per day, ane the présent consumption of coal, as it actually is taking place, I am informed, is 44 tons a day, to produce 9 1/2 knots. The différence by that calculation, taking into account the reduced days of voyage, would be 150 tons per voyage, and 150 tons per voyage, multiplied by 52 voyages, will give 7800 tons a year; therefore, on the Indian side, you will hâve to increase the cost by 27 300 1. for coal. I hâve also taken on the European side to increase the speed to 12 knots an hour, and running the same number of voyages, you will require to increase your consumption of coal 169 tons a voyage, or 8800 tons in the year, or 15 800 L, that is between Marseilles to Alexandria. That would give a total of 43 000 1. a year additional for coal, if you accelerated the speed from 10 knots, which isthe présent speed on the European side, to 12 knots, and from 9 or 9 1/2 knots, which is the présent speed on the Indian side, to 11 knots; and a voyage weekly, each way, that is, 52 complété voyages out and home, or 104 trips, Then I hâve taken 36 tons per day as the quantity which they are bur- ning on the European side, going at 10 knots an hour, which I am informed is their quantity. And I would call the attention of the Committee liere to the reason why 1 hâve suggested a différence of a knot an hour in the two services, and so small a différence in the quantity ol'coal for the different speeds.
