Geodaesia, or, The art of surveying and measuring land made easy : shewing by plain and practical rules, to survey, protract, cast up, reduce or divide any piece of land whatsoever; with new tables for the ease of the surveyor in reducing the measure of land : moreover a more facile and sure way of surveying by the chain, than has hitherto been taught : as also to lay out new lands in America, or elsewhere : and how to make a perfect map of a river's mouth or harbour; with several other things never before published in our language /
