AbstractFew realize that more branches of human knowledge contribute to the production of a topographical survey sheet than to any other single object that could be named off-hand. We have made great strides since the days of Swift: elephants, whales, etc., are no longer regular cartographical features. From astronomy to chemistry science plays an increasing part, while art tends to languish. Some there are who love the old styles and ornamentation; yet the latter assort ill with ample and accurate data. 相似文献

AbstractTHE very interesting article on “Road-surveying in the East” by J. N. List appearing in NO. 6 of the Review suggests that the following notes on the methods of road location used in the Gold Coast may be of interest. These methods enter into considerably more detail than those described by Mr. List and are of proved economic value. 相似文献

AbstractAs a survey cadet I suppose one accepted the “tricks of the trade” without question. To turn out of the tent at crack of dawn, cook breakfast, and later devote a few idle moments to light pipes, pull on half-dried boots, pack the tucker bag and billy, then set off to work through wet fern and scrub; to boil the billy in the rain-soaked bush, then trek back again at dusk, with more food to cook for supper by the light of a flickering candle,—all added to the day's work, seldom arousing much enthusiasm in the youngest member of the party. Looking back one realizes how much knowledge was gained unintentionally. 相似文献
