it is above the horizon long before dusk. In the same way the 

 waning "crescent " does not set ; it is only eclipsed by the light 

 of the rising sun. Neither the crescent nor the decrescent is 

 ever seen high in the sky. 



NOTES ON BOOKS. In beginning a course on the Physical Environment 

 the teacher will naturally in the first instance have recourse to the ordinary 

 school manuals of physical geography. It is unnecessary to give a list 

 of these, the revised edition of Huxley's Physiography, published as 

 Physiography by Huxley & Gregory (London, 1904), may be named as a 

 good example. For reference a text-book of meteorology is useful, such 

 as Dickson's Meteorology (London, 1893), or Davis' Elementary Meteorology 

 (Boston, 1894). The Atlas of Meteorology, by Bartholomew, Herbertson, & 

 Buchan (Edinburgh, 1899), is invaluable, and Hann's Climatology, First Part 

 translated by Ward as General Climatology (New York and London, 1903), is 

 also almost indispensable. The raw material of the science of meteorology, no 

 less than special studies on the subject, is to be found in the publications of the 

 Meteorological Societies, notably in the Journal of the Scottish Meteorological 

 Society, where in addition to the monthly records of temperature, rainfall, etc., 

 for Scotland, there are numerous valuable papers on climate, temperature, 

 rainfall, etc., especially the classical papers written by Dr. Buchan. See also 

 the Quarterly Journal of the Royal Meteorological Society, and the annual volume 

 of the British Rainfall Organisation (published at London yearly as British 

 Rainfall), and Symons' Meteorological Magazine. The Royal Meteorological 

 Society also publishes two little pamphlets which teachers will find useful 

 Hints to Meteorological Observers, and Some facts about the Weather, both written 

 by W. Marriott, assistant secretary, which are revised from time to time. 

 If any detailed observations are to be made, the Weather Reports of the 

 Meteorological Office are almost a necessity. Application for these should be 

 made to the Office, 63 Victoria Street, London, S.W. ; the Daily Report can also 

 be bought at certain of the railway stations in London. 



The facts as regards climate and weather, considered in their geographical 

 relationships, will be found treated in such books as Britain and the British Seas, 

 by H. J. Mackinder (second edition, Oxford, 1907), G. S. Chisholm's Commercial 

 Geography (seventh edition, London, 1908), and The International Geography, edited 

 by H. R. Mill (London, 1907). In the Scottish Geographical Magazine various 

 articles have appeared recently on climate and weather ; mention may be made 

 especially of the author's The Study of the Weather as a Branch of Nature Know- 

 ledge (xxiii., 1907), and The Climate of the British Isles, by Andrew Watt (xxiv., 

 1908). Some useful suggestions as to the best way of including the subject in 

 a general Nature Study course will be found in Some Suggestions to Teachers for 

 Seasonal Nature Study in Schools, by J. A. Thomson (Aberdeen, 1908). 



For the subjects discussed in the later chapters the following books may be 

 mentioned : An Introduction to Practical Geography, by Simmons & Richardson 

 (London, 1907), a little book packed with useful practical suggestions ; Practical
