Abstract

(1) PROF. KEILHACK has produced a bookon water-supply which presents a remarkable contrast with the brief treatment of the subject in many works on engineering. Yet he regards these five hundred tall and handsome pages as constituting a preliminary “Lehrbuch,” leading up to a future “Handbuch” of Teutonic magnitude. The geologist here subordinates himself willingly to his technical purpose. The kinds of rocks are dealt with in a few short sentences, but their structure and the passage-ways for water in them are at once impressed upon the reader as of paramount importance. The characters of soils as water-bearers receive rather slight attention, and the necessity for discriminating between the “fine earth” used experimentally and the soil as part of the earth's crust, with all the stones in it, seems left to the intelligence of the reader.
