Here, amid these long lines of Roman entrenchments, occurs again the mysterious name of "Coldharbour," a perplexing place-name that is found no less than 170 times in England, in situations the most diverse and in districts widely scattered. At least twenty-six of these Coldharbours are to be found on the ordnance maps of Kent, and six of them on, or closely adjoining, the Dover Road. Their situation, scattered thus along the old military _via_ of Watling Street, adds greatly to the force of the argument that this singular name has some connection with Roman times, but what connection, and what is the real meaning of the name, not all the acumen and ingenuity of archaeologists has ever been able to satisfactorily explain. The fact of the great majority of Coldharbours lying by the site of Roman roads or camps has led to the ingenious theory that they first acquired their name in Saxon times when, the country being wasted with ruthless and decimating wars, the Roman villas still remaining were destroyed, and great desolate tracts of country created. Travellers (this theory goes on to say) could find no other shelter on their journeys save the ruined walls of the once magnificent palaces that the Romans had left; and as they crouched, shivering, to leeward of these ruinated and roofless remains of a decayed civilization, and tried to warm themselves at fires painfully and laboriously made of leaves and sticks, they called them "cold harbours." Unhappily for this theory, the places called "Coldharbour" are by no means always situated in exposed situations, and no remains of buildings have been discovered on their actual site, although their neighbourhood is frequently found to be rich in Roman remains. A suggestion has been made that "cold" is a variant of "cool," and that, far from being the miserable refugees of forlorn travellers, the Coldharbours were really the "Mount Pleasants" and "Belle Vues" of ancient times, to which our remote forbears resorted for "a breath of air." We should probably be within our rights in deriding this suggestion as a theory made to fit a fertile imagination, but it is not safe, in the presence of such an apparently insoluble problem, to do more than present a few of the derivations advanced. It would be equally rash to assume that the stations of the "colubris arbor," the Roman serpent-standard, gave their name to these places, although the idea is plausible enough.
