7°|o Guaranteed Farm Mortgages 7°|o 



The Guarantee Investment Company makes loaiis upon fertile farms in the choicest portions of Kansas and Nebraska 

 and has adopted the policy of sending a Committee of its Investors each year to examine its loans and methods of bicsiness. 



The Committee this year consisted of FROF. A. H. BERIIN, Principal of the High School Montrose, Fa., and 

 MA J. THEODORE L. FOOLE, Ex- U. S. Fension Agent, Syracuse, N. Y. Both of these gentlemen are persons of 

 the highest character and have the confidence of the Communities in which they reside. 



The Committee has recently returned and has made a very interesting Report upon the general development of Kansas ana 

 Nebraska as ivell as the business of the Company. The Company 7vill be glad to send this Report to any address.

Address for Report and Monthly Bulletin 



HENRY A. RILEY, General Eastern Manager, 191 Broadway, N.Y. 



Ives Strata Map of part of the United States of America and Canada, 



III Avliicli tlie Architecture of the Earth's Crust is Graphically Exhibited, Illustrating Fundamental Facts 

 alike of 



STRUCTURAL GEOLOGY AND PHYSICAL GEOGRAPHY. 



The Strata Map is a device for the more efficient teaching of Physical Ge- 

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

 Superimposed Maps, of different coloks, representing the several geological 

 formations of the district, enclosed In a glazed frame, the whole hinged to ad- 



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

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

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

 be bent to show synclinal or anticlinal folds. 



OFINIOISrS OF EMUSrENT Gi^EOLOGHSTS. 



Yale University. Professor James D. Dana. 



" Well fitted for the use of Instruetion in the 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." 

 Johns Hopl<ins University. President D. C. Oilman. 



'' 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.'' 

 Micliigan 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 tchools." 

 Cornell University. Professor H. Shaler Williams. 



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

 representing the grand facts of stratigraphy In the Eastern United 

 States." 

 Columbia College, New Yorl<. 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. 



■'A m satisfied that its use wlU greatly assist students to understand 

 the geological structure of the country." 



SIZE 30x24 INCHES. PRICE S17.50. 



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, tor 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 direction of a want long felt by Teachers of Geology aad 

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

 U. S. 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 in 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 and students." 

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



" It Is very neatly done and must prove a great help to intelligent 

 teaching and studying of Geological Science."
