In a sketch such as the present, outlines alone are possible, detail cannot be elaborated. If it has suggested enough of atmosphere to show the vastness of the landscape spreading out before our eyes back into the past and on into the future, the task has been accomplished. There are many detailed volumes which follow out one or other special line of enquiry along the highroads and by-ways of this long traverse in creation. If the bird’s-eye view of the country given in this book entices some to foot it yard by yard under the guidance of specialists for each district, it will have done its part. While to those who will make no intimate acquaintance with so far off a land it presents a short account by a traveller, so that they may know something of the main features and a little of the romance of the fossil world. APPENDIX I LIST OF REQUIREMENTS FOR A COLLECTING EXPEDITION In order to obtain the best possible results from an expedition, it is well to go fossil hunting in a party of two, four, or six persons. Large parties tend to split up into detachments, or to waste time in trying to keep together. Each individual should have strong suitable clothes, with as many pockets arranged in them as possible. The weight of the stones can thus be distributed over the body, and is not felt so much as if they were all carried in a knapsack. Each collector should also provide himself with— A satchel or knapsack, preferably of leather or strong canvas, but not of large size, for when the space is limited selection of the specimens is likely to be made carefully. One or two hammers. If only one is carried, it should be of a fair size with a square head and strong straight edge. One chisel, entirely of metal, and with a strong straight cutting edge. Soft paper to wrap up the more delicate fossils, in order to prevent them from scraping each other’s surfaces; and one or two small cardboard boxes for very fragile specimens. A map of the district (preferably geologically coloured). Localities should be noted in pencil on this, indicating the exact spot of finds. For general work the one-inch survey map suffices, but for detailed work it is necessary to have the six-inch maps of important districts. A small notebook. Few notes are needed, but those few _must_ be taken on the spot to be reliable. A pencil or fountain pen, preferably both. A penknife, which, among other things, will be found useful for working out very delicate fossils. APPENDIX II TREATMENT OF SPECIMENS 1. The commonest form in which fossils are collected is that which has been described as _impression material_ (see p. 12). In many cases these will need no further attention after the block of stone on which they lie has been chipped into shape.
