I left a day after. Before long I got a letter from my friend, brief but to the point: "All quiet, old boy; come again."


THE MEREWIGS

During the time that I lived in Essex, I had the pleasure of knowing Major Donelly, retired on half-pay, who had spent many years in India; he was a man of great powers of observation, and possessed an inexhaustible fund of information of the most valuable quality, which he was ready to communicate to his intimates, among whom was I.

Major Donelly is now no more, and the world is thereby the poorer. Major Donelly took an interest in everything—anthropology, mechanics, archæology, physical science, natural history, the stock market, politics. In fact, it was not possible in conversation to broach a subject with which he was wholly unacquainted, and concerning which he was not desirous of acquiring further information. A man of this description is not to be held by lightly. I grappled him to my heart.

One day when we were taking a constitutional walk together, I casually mentioned the "Red Hills." He had never heard of them, inquired, and I told him what little I knew on the matter. The Red Hills are mounds of burnt clay of a brick-red colour, found at intervals along the fringe of the marshes on the east coast. Of the date of their formation and the purpose they were destined to discharge, nothing has been certainly ascertained. Theories have been formed, and have been held to with tenacity, but these are unsupported by sound evidence. And yet, one would have supposed that these mysterious mounds would have been subjected to a careful scientific exploration to determine by the discovery of flint tools, potsherds, or coins to what epoch they belong, and that some clue should be discovered as to their purport. But at the time when I was in Essex, no such study had been attempted; whether any has been undertaken since I am unable to say.

I mentioned to Donelly some of the suppositions offered as to the origin of these Red Hills; that they represented salt-making works, that they were funereal erections, that they were artificial bases for the huts of fishers.

"That is it," said the major, "no doubt about it. To keep off the ague. Do you not know that burnt clay is a sure protection against ague, which was the curse of the Essex marsh land? In Central Africa, in the districts that lie low and there is morass, the natives are quite aware of the fact, and systematically form a bed of burnt clay as a platform on which to erect their hovels. Now look here, my dear friend, I'd most uncommonly like to take a boat along with you, and explore both sides of the Blackwater to begin with, and its inlets, and to tick down on the ordnance map every red hill we can find."

"I am quite ready," I replied. "There is one thing to remember. A vast number of these hills have been ploughed down, but you can certainly detect where they were by the colour of the soil."

Accordingly, on the next fine day we engaged a boat—not a rower—for we could manage it between us, and started on our expedition.
