Nevertheless, as a place of call for refreshment, for ships passing through the Channel, Mozambique has some claims to attention. Abundance of vegetables and fruit are to be obtained there; pigs and goats are readily to be purchased, as well as poultry, and, were the demand for bullocks larger, they would soon be brought to market in numbers. At present, however, they are very dear. But the great treasure of the place remains yet to be developed; at all events, the subject is well open to investigation. The existence of good coal in that neighbourhood is now, I believe for the first time, made public. There is reason to expect that it will be found in large quantity, and of good quality, although as yet the search for it has not been carried on to any great extent. The all-engrossing subject of the slave-trade seems to darken every other object of attention in that quarter, and the Portuguese are probably afraid that the discovery of coal in their settlements would occasion the continual visits of so many steamers and other vessels, that even greater difficulty would be thrown in the way of the traffic. Just as the Nemesis was leaving the harbour, the captain of an English merchant ship, the only one there at the time, brought off a large piece of excellent coal for inspection. It had all the appearance of coal perfectly adapted for steaming purposes; it was stated to be found at Quillimane, (the settlement before alluded to) about three hundred miles to the southward of Mozambique, and that there is every reason to believe it might be procured in large quantities, and worked without difficulty. This specimen was sent to England for examination, by Captain Hall; but it has since been ascertained that it did not reach its destination. This is on all accounts to be regretted. It was sent down to the Cape of Good Hope from Mozambique, in a box, with directions that it should be forwarded to the India House, but was probably lost, or set aside at the Cape. If further investigation should prove what is here stated to be correct, there can be no reason for not searching for coal upon other parts of the coast; and under any circumstances, as Quillimane is so short a distance from Mozambique, the coal might easily be brought up to the latter at little expense; and, if it were to become a more frequented route to India, it would be desirable to moor a large coal-hulk off the town, in which a constant supply of coal could be kept ready, and which could be taken in rapidly, and at little expense, by a steamer running up alongside of her.
