1042 EXPERIMENT STATION RECORD. 



The art of landscape gardening, H. 'Repton {Bo>ston and New York. 1907, 

 pp. A' A'/// +252, pis. 22, pr/s. 28). — This is the first of a series of classics in 

 landscape architecture undertalven at the suggestion and with the cooperation 

 of the American Society of Landscape Architects and edited by J. Nolen. 



Tlie present volume includes what are considered two of the best works of 

 Humphry Repton, an early English landscape gardener, as follows: Sketches 

 and Hints on Landscape (hardening, published in 1795, and Theory and I'ractice 

 of Landscape Gardening, published in 1803. These have been reprinted, illus- 

 trated in modern form, and edited to serve modern conditions. The first-named 

 work is prefaced by general remarks on landscape gardening, and succeeding 

 chapters deal with the discussion of different characters and situations, build- 

 ings, proper situations for a house, water, large private places, formal garden- 

 ing, approaches, affinity between painting and gardening, and sources of pleas- 

 ure in landscape gardening. The second work is prefaced by some general obser- 

 vations on taste; the introduction treats of the general principles of landscape 

 gardening, utility, scale, examples of compai*ative proportion, and use of the 

 perspective, and succeeding chapters deal with the treatment of grounds, water, 

 various forms of planting, woods, fences, vines, farms, i)arks, and pleasure 

 grounds, a discussion on landscape gardening as related to painting, ancient and 

 modern gardening, variety of situation and character, architecture and garden- 

 ing, and the formation of a new place, with concluding remarks concerning color 

 and the difficulty of comparisons between art and nature. 



Several notes by the author, dealing with various phases of landscai)e garden- 

 ing, are appended to the volume. 



FORESTRY. 



The relation of the Southern Appalachian Mountains to the development 

 of water power, M. O. Leighton, M. R. Hall, and R. H. Bolster (U. H. Dcpt. 

 Agr., Forest Serv. Circ. 14-'h PP- 5'/). — In connection with a survey made of the 

 Appalachian and White Mountain watersheds under the direction of the Secre- 

 tary of Agriculture, the report of whicli has been previously noted (E. S. R., 

 19, p. 948) arrangements were made with the Geological Survey for a study of 

 the water resources of the Southern Appalachian ^Mountains. The present cir- 

 cular embraces the results of that study. 



The measurements and estimates on the discharge of streams and water 

 storage facilities of the rivers of that region as related to the production of 

 water power are based on the data accumulated at the regular measurement 

 stations maintained by the Survey during the past 7 years as well as on that 

 secured from a special study made in 1907. The various rivers studied were 

 divided into sections of convenient leugtli and of similar character, and deter- 

 minations were niiide of the mean drainage area of each section, the minimum 

 discharge and horsepower, and the minimum discharge and horsepower during 

 the ti high-water months, and estimates were made of the horsepower available 

 from storage during periods of 3, 0, and 12 months. These data are presented 

 in tabular form. Desirable sites for storage reservoirs were also selected and 

 their capacities determined. The data relative to these reservoirs are here 

 given. 



According to estimates made from this work, there is a minimum of about 

 2,800,000 indicated horsepower developed by the rivers originating in the 

 Southern Appalachian JNIountains, of which it is estimated that at least 50 per 

 cent is available for economic development, providing the i)resent forests of the 

 mountains are protected from this time on. The importance of preserving these 

 forests is strongly pointed out.
