The best time for vessels to sail from Suez for India, &c. is therefore about the end of August, which will enable them to clear the Straits of Bab-el-Mandeb in September, before the easterly winds commence in the Gulf outside.

From all these facts it will appear,

1st. That the passage between India, &c., and the Gulf of Aden, may be made with ordinary facility by sailing vessels.

2nd. That some delay would be experienced by sailing vessels in the Gulf of Aden during certain portions of the year, whether bound to or from India; and also by vessels coming from India, in the northern part of the Red Sea, during the greater part of the year.

Against these difficulties in the Red Sea route must, however, be set off the delays by calms and contrary winds, between the trades experienced by vessels navigating by the Cape route. In order to ascertain how nearly they may balance each other, and consequently whether a saving of time in navigating by the Mediterranean and Red Sea, proportionate to the shorter distance, as compared with the voyage round the Cape of Good Hope, might be effected, I would beg leave to submit the following questions to the consideration of experienced nautical men.

1st. Is the navigation by a sailing vessel, between England and Pelusium, say 3000 miles, of equal facility as a similar distance from England on the Cape route?

2nd. Is the navigation to or from the given point, to the southward of Ceylon and Cape Guardafui, more certain than that of an equal distance between the same point and the Cape of Good Hope?

3rd. Would the impediments in the navigation of the Red Sea and Gulf of Aden, already pointed out, be greater or less than those experienced from calms and contrary winds between the trades in navigating by the Cape of Good Hope route? And, assuming that the answer to the second query should be in favour of the Red Sea route, would that gain set off against the difficulties of navigating the Red Sea and Gulf of Aden, and reduce the latter to a par with the impediments between the trades just alluded to?

4th. Would not the nature of the coast of Egypt, at the embouchure of the Canal in the Mediterranean, present considerable difficulty and danger to sailing vessels approaching it for the purpose of seeking the Canal entrance? The coast, it is well known, for a distance of upwards of 150 miles to the eastward, as well as to the westward of the Canal entrance, is destitute of any sheltered anchorage, is exceedingly low, and not easily discoverable until within a short distance of it, and very shallow at a distance of two leagues from the shore. A good light on the pier or breakwater might obviate some of the danger, but still it is to be apprehended, that sailing vessels approaching this part of the coast, with the wind strong from the north and north-west, and which is very prevalent, would incur considerable risk of getting embayed and being driven ashore.
