— The A?nerzcan Garden of New York has taken another step 

 forward by the incorporation of its business under the title of" The 

 Garden PubUshing Company, Limited." The management goes 

 on largely in the same hands, but with the more intimate connec- 

 tion of several able men, who really have had much to do in mak- 

 ing T/ie Amerzca?i Garden what it has become ; and, with in- 

 creased means, the editor expects to more rapidly improve the 

 magazine, and increase the business in proper lines. The organ- 

 ization of the new company stands as follows : Lawson Valentine, 

 president ; Charles Barnard, vice-president ; L. H. Bailey ; John 

 DeWolf, secretary ; Edgar H. Libby, treasurer. Mr. Valentine is 

 also president of the Christian Union Company ; a prominent mem- 

 ber of the great publishing-house of Houghton, Mifflin. & Co., 

 owner of Houghton Farm ; and president of the Lawson Valentine 

 Company, makers of fine varnishes. Mr. Barnard is connected 

 with The Century Company, author of that wonderfully successful 



drama, " The County Fair, " author of numerous successful books 

 on technical subjects, and a practical horticulturist as well. Pro- 

 fessor Bailey is head of the new horticultural department at Cor- 

 nell University, and a thoroughly practical man of wide experience. 

 Mr. DeWolf is a professional landscape-gardener, for several years 

 head of the art department and assistant editor of The American 

 Garden. Mr. Libby has been the editor and publisher for four 

 years and a half, and has pushed the business with hard work and 

 exceptional skill. 



— The editorial management of the North American Review is 

 at present in the hands of Mr. William H. Rideing. 



— Macmillan & Co. will publish shortly an appendix to Grove's 

 " Dictionary of Music and Musicians," which completes the fourth 

 and concluding volume of the work. A full index to the work is 

 in preparation, which will be published later in a separate volume.

IN PRESS FOR EARLY PUBLICATION. 



Ives strata Map of the United States, 



In which the Architecture of the Earth's Crust is Graphically Exhibited, Illustrating Fundamental Facts 

 alike of 



STRUCTURAL GEOLOGY AND PHYSICAL GEOGRAPHY. 



Tbe Strata Map is a device for the more efficient teaching of Physical 

 Geography and Elementary Geology 1h Schools. It consists of a series of 

 Superimposed Maps, of different colors, representing the several geologl- 

 cal formations of the district, enclosed in a frame, the whole hinged to ad- 



mit of examination In detail. By Its means superposition^ denudation, and 

 outcrop of strata are graphically exhibited, with the phenomena of escarp- 

 ments, outliers^ inliers, dip, strike., conformability., &c., and the Cards may 

 be bent to show synclinal or anticlinal folds. 



OF'INIONS OF EMINEISTT G-EOLOG-ISTS. 



Yale University. Professor James D. Dana. 



" Well fitted lor the use of Instruction In tlie science." 



Professor Addison E. Virrill. 

 " It will be of very great advantage in the teaching of geology." 

 Harvard University, Professor N. S, Shaler, 



" An extremely useful adjunct to our means of illustration." 

 Jolins Hopkins University, President D, C. Gilman, 



'' Wherever American geology is taught your map should be a part 

 of the apparatus." 

 Pennsylvania University, Professor Geo. A. Koenig. 



'^ The map will be of special use in schools, which can only de- 

 vote a short time to the study of Geology." 

 Michigan University. Professor Alexander Winchell. 



** It seems to me that the device will commend the study of Geol- 

 ogy to many persons who might otherwise regard the subject as dif- 

 ficult and uninviting. The work prepared by Mr. Ives ought to be used 

 extensively in American t-chools." 

 Cornell University. Professor H, Shaler Williams. 



" A valuable aid to teachers of geology as a means of graphically 

 representing the grand facts of stratigraphy m the Eastern United 

 States." 

 Columbia College, New York, Professor J. S, Newberry, 



" A valuable aid in teaching geology, giving as it does to the stu- 

 dent a clear idea of the superposition of the different geological sys- 

 tems at a glance." 

 Dartmouth College, Hanover, N. H, Professor C. H, Hitchcock. 



"Am satisfied that its use will greatly assist students to understand 

 the geological structure of the country." 



Academy of Natural Sciences of Philadelphia. Professor Angelo Heilprin, 



"The representation of Strata, as imposed one upon the other, by 

 means of cardboard is certainly a good plan, for apart from rendering 

 more intelligible the general expressions of the Map, It permits of 

 ready alteration and the possibility of constantly bringing the map up 

 to date, in other words to make it conform to more recent discoveries." 

 Boston Society of Natural History- Professor Alpheus Hyatt. 



" Your map representing superposition and the various phenom- 

 ena of geological science, so far as the distribution of rocks on this 

 continent is concerned, has greatly interested me. I think that in the 

 hands of a good teacher it would prove an efficient and useful adjunct 

 in the teaching of geology." 

 American Museum of Natural History. Professor R. P. Whitfield. 



" In the direciion of a want long felt by Teachers of Geology aod 

 will undoubtedly be appreciated by them as well as by the student." 

 U. Si Geological Survey. Major J. W, Powell, Director 



" After examination I am able to state that the work has been ex- 

 ecuted with care and fidelity, and I believe it will be a valuable aid to 

 teachers." 

 New York State Survey. Professor James Hall, State Geologist 



" I believe that maps constructed upon this method would be ex- 

 tremely useful iu the hands of competent teachers." 

 Pennsylvania Survey, Professor J. P. Lesley, State Geologist. 



" A piece of new and useful apparatus for teaching Geology, by 

 representing to the eye of the student the areas of superimposed for- 

 mations. I cordially recommend it to teachers tmd students." 

 New Jersey Survey. Professor Geo, H, Cook, State Geologist, 



" It is very neatly done and must prove a great help to inteliigeut 

 teaching and studying of Geological Science."
