B. Text-Books.

The Story of the Earth’s Atmosphere. Douglas Archibald. New York, D. Appleton & Co., 1898. 18mo, pp. 194. 40 cents.

To be recommended to the general reader who wishes to gain some knowledge of meteorology quickly. Not a text-book. Contains a chapter on “Flight in the Atmosphere.”

Elementary Meteorology. William Morris Davis. Boston, Ginn & Co., 1898. 8vo, pp. 355. $2.50.

The most complete of the modern text-books, and the best adapted for use in the systematic teaching of meteorology. The modern views are presented clearly and without the use of mathematics. Portions of it are somewhat too advanced for school study, but teachers will find it invaluable as a reference book in directing the laboratory work, and in answering the questions of school classes.

A Popular Treatise on the Winds. William Ferrel. New York, John Wiley & Sons, 1890. 8vo, pp. 505. $3.40.

This can hardly be regarded as a popular treatise. It embodies, in condensed and chiefly non-mathematical form, the results of Ferrel’s researches during his long and profound study of the general circulation and phenomena of the atmosphere. Teachers who advance far into meteorology will find this book indispensable. It is not at all suited for general class-room use.

American Weather. A. W. Greely. New York, Dodd, Mead & Co., 1888. 8vo, pp. 286. Out of print, but secondhand copies are probably obtainable.

Deals, as the title implies, especially with the weather phenomena of the United States. Contains brief accounts of individual hot and cold waves, hurricanes, blizzards and tornadoes, and gives specific data concerning maxima and minima of temperature, precipitation, etc., in the United States.

Meteorology: Practical and Applied. John William Moore. London, F. J. Rebman, 1894. 8vo, pp. 445. 8 shillings.

A readable book. Considerable space is given to instrumental meteorology. Contains chapters on the climate of the British Isles and on the relations of weather and disease in the British Isles. Especially adapted for the use of English readers.

Elementary Meteorology. Robert H. Scott. International Scientific Series. London, Kegan Paul, Trench & Co., 1885; Boston, A. A. Waterman & Co., 1889. 8vo, pp. 410. 6 shillings.

The standard text-book in Great Britain. The author is secretary to the Meteorological Council of the Royal Society. Fairly complete, but now somewhat out of date in some portions. It is a useful book in a meteorological library, but does not treat the subject in a way very helpful to the teacher.

Meteorology. Thomas Russell. New York, The Macmillan Company, 1895. 8vo, pp. 277.

Brief and incomplete as a text-book of meteorology, but containing a very comprehensive account, fully illustrated, of rivers and floods in the United States, and their prediction.

Elementary Meteorology. Frank Waldo. New York, American Book Company, 1896. 8vo, pp. 373. 90 cents.

A compact summary. Useful to teachers as a handy reference book.

Modern Meteorology. Frank Waldo. New York, Charles Scribner’s Sons, 1893. 8vo, pp. 460. $1.25.

Very complete account of meteorological apparatus and methods, and admirable summary of recent German studies of the thermodynamics and general motions of the atmosphere.

C. Instructions in the Use of Instruments.

Instructions for Voluntary Observers. 1899. 8vo, pp. 23. Brief instructions for taking and recording observations of temperature and precipitation with ordinary and maximum and minimum thermometers and with the rain gauge.

D. Journals, etc.

Monthly Weather Review. Prepared under the direction of Willis L. Moore, Chief of Weather Bureau, Professor Cleveland Abbe, Editor. United States Department of Agriculture, Weather Bureau, Washington, D. C. 10 cents a copy.

An invaluable publication for teachers and students alike. Contains complete meteorological summaries for each month; accounts of all notable storms, cold and hot waves, etc.; and a large number of articles on a wide range of meteorological subjects. The charts show the tracks of areas of high and low pressure which crossed the United States during the month, the total precipitation, sea-level pressure, temperature and surface winds, percentage of sunshine, etc., for the month. Other charts are also frequently added.

The Journal of School Geography. Professor Richard E. Dodge, Teachers College, Columbia University, New York City, Editor. Publication Office, 41 No. Queen Street, Lancaster, Pa. Ten numbers a year. $1.00 per annum.

A monthly journal devoted to the interests of the common school teacher of geography. Contains numerous articles and notes on meteorological and climatological subjects.

Science. Edited by Professor J. McK. Cattell, Columbia University, New York City, New York, The Macmillan Company. Weekly. $5.00 per annum.

Monthly Bulletins of the Climate and Crop Service of the Weather Bureau.

These Bulletins are issued every month at the central office of the Weather Bureau in each State, under the direction of the Section Director of the Climate and Crop Service in that State. They contain meteorological data for the month, and frequently notes of interest. The annual summaries are especially valuable.

E. Charts.

Daily Weather Maps. These are published at the central office of the Weather Bureau in Washington, and at eighty-four other stations of the Bureau throughout the United States. It is best to have the daily maps sent from the nearest map-publishing station, and not from Washington, as the delay in the latter case is often so great that much of the immediate value of the maps is lost.

Climate and Crop Bulletin of the United States Weather Bureau. Washington, D. C. Monthly.

Chart showing, by means of small maps, the actual precipitation, departures from normal precipitation, departures from normal temperature, and maximum and minimum temperatures. Also a printed summary of the weather and of the crop conditions in the different sections of the United States. Issued on the first of each month.

Snow and Ice Chart of the United States Weather Bureau. Washington, D. C. Weekly during the winter season.

Based on data from regular Weather Bureau stations, supplemented by reports from selected voluntary observers. Shows, by shading, the area covered with snow at 8 P.M. each Tuesday during the winter, and by lines, the depth of snow in inches. Explanatory tables and text accompany the chart.

Storm Bulletin of the United States Weather Bureau. Washington, D. C. Issued at irregular intervals.

Charts, with text, illustrating the history of individual notable storms.

Pilot Chart of the North Atlantic and North Pacific Oceans. Hydrographic Office, Bureau of Equipment, Department of the Navy, Washington, D. C. Monthly. Price 10 cents a copy.

Shows calms and prevailing winds, ocean currents, regions of fog and equatorial rains, the positions of icebergs and wrecks, steamship and sailing routes, storm tracks, magnetic variation, etc. Also gives isobars and isotherms and a forecast for the month succeeding the date of publication, and a review of the weather over the oceans for the preceding month. Supplementary charts are occasionally issued.

Rainfall and Snow of the United States as compiled to the End of 1891, with Annual, Seasonal, Monthly, and other Charts. Mark W. Harrington. United States Department of Agriculture. Weather Bureau, Bulletin C, Washington, D. C. 1894. Atlas, 18 × 24 inches. Charts 23. Text, 4-80 pp.

Contains twenty-three charts as follows: Monthly rainfall, seasonal rainfall, annual rainfall, monthly snowfall, monthly maxima of rainfall, rainy seasons, details of rainfall, details of occurrence of thunderstorms. Well adapted to serve as illustrations for use in the class-room. The text is explanatory, and is published separately in quarto form.

Rainfall of the United States, with Annual, Seasonal, and other Charts. Alfred J. Henry. United States Department of Agriculture, Weather Bureau, Bulletin D, Washington, D. C. 1897. 9¹/₄ × 11¹/₂ inches. Pp. 58. Charts 10. Plates III.

A more recent publication than the preceding one, the averages having been compiled to the end of 1896. The charts are smaller than most of those in Bulletin C, and therefore not so well adapted for class-room illustration. The chart of mean annual precipitation is the latest and best published. The rainfall of the crop-growing season receives separate treatment, and is illustrated by means of two charts. The discussion in the text is excellent.

F. Meteorological Tables.

Smithsonian Meteorological Tables. Smithsonian Miscellaneous Collections, 844. Washington, D. C. 1893. 8vo. Pp. 262.

A very complete set of tables.

Handbook of Meteorological Tables. H. A. Hazen (of the United States Weather Bureau). Washington, D. C. 1888. 8vo. Pp. 127. $1.50.

Contains forty-seven tables, comprising all that are needed by the working meteorologist. Includes tables for Fahrenheit and Centigrade conversions, for barometric hypsometry and reduction to sea level, for the psychrometer, etc.

Tables for Obtaining the Temperature of the Dew-Point, Relative Humidity, etc. United States Department of Agriculture, Weather Bureau, Washington, D. C. 1897. 8vo. Pp. 29.

These are the tables now in use by the Weather Bureau.

G. Illustrations.

Classification of Clouds for the Weather Observers of the Hydrographic Office. Hydrographic Office, Bureau of Navigation, Department of the Navy, Washington, D. C. 1897. Sheet of twelve colored views. Price 40 cents. In book form, with descriptive text, $1.00.

An excellent set of cloud views, classified according to the International Nomenclature. The text describes the various cloud forms and shows their value as weather prognostics. An attractive addition to the furnishings of a schoolroom.
