Minor Prehistoric Remains of Britain. 121 care, and the materials removed restored if possible on the completion of the work, so as to avoid any permanent dis- figurement. The so-called "exploration" of many ancient structures, whose venerable antiquity should have rendered them sacred, has often been conducted in a manner which can only be called an act of desecration. How frequently do we read in local histories such statements as the following :— " On------Common there formerly stood a large mound of earth supposed to be a tumulus, which was opened by Mr.------in the year------, but nothing of any interest was found, except a few fragments of pottery and some decayed bones"! Such passages as this, which is not a verbatim extract, but simply an ideal specimen illustrating the kind of destruction that has been going on, lead to the supposition that the prevailing idea in opening a tumulus is the discovery of hidden treasure. Any other find is considered devoid of interest, and the scientific value of the structure is for ever lost by the scattering of its contents. The ancient monument committees of local societies, in addition to the preparation of catalogues and the conducting of explorations, would have another important function to fulfil; they might take upon themselves the duties of vigil- ance committees, keeping a watchful eye upon the ancient remains in their neighbourhood, and preventing as far as possible their destruction. In the case of minor remains which were not considered worth scheduling for State protec- tion, opportunities would often occur for investigating with- out incurring the expense of systematic excavations. In the course of building or agricultural operations, old ramparts are frequently cleared away in perfect ignorance of their value to the archaeologist: or again, a new road has to be made, which in its course passes through the remains of some ancient earthwork, now almost obliterated by the hand of of time. In such cases the vigilance committee, having pre- viously catalogued the remains threatened, would endeavour to come to some arrangement with the owner of the property, and obtain permission to appoint watchers, for the purpose of recording the nature and position of any relics that might be
