Excerpt from Handbook of the Southern Nigeria Survey and Text Book of Topographical Surveying in Tropical Africa This Handbook contains the Rules and Regulations which govern the Southern Nigeria Survey in the matter Of organisation and administration, and also lays down the principles on which the technical details Of all Topographical Survey Work are to be executed and in which all Survey pupils are to be instructed. As a text-book it does not pretend to be complete, but rather to adapt existing systems to what may be fairly described as very difficult local conditions, both climatic and topographical. Undoubtedly the most satisfactory method of surveying a country is by what may be called exact systems, but the more exact the system the greater the cost Of survey. Hence, the surveyor must adopt a fair mean between accuracy and cost, - must make a judicious proportionate use Of the theodolite and compass, Of the level and the aneroid, Of'the steel band and the human stride, - in short, must cut his coat according to the cloth.
