MAPS. 31 



geographical position of each state or country may be readily ex- 

 plained, and it is obvious that by the use of such a series of 

 maps as a transparency, together with the map of the world, 

 and the illuminated globe, the study of geography may be 

 taught with a great saving of time and expense, and may also 

 be taught to those whose sight does not admit of close study at 

 night, as well as those who have no leisure hours to devote to 

 study except at night. The perfection of this system, however, 

 will not be attained until skillful artists shall have turned their 

 attention to the subject, for the purpose of illustrating the maps 

 by the best designs, and most truthful representations of the 

 scenery, productions, and costume of the inhabitants of the 

 different countries, and blending these with the geographical 

 outlines. 



The panoramic representations, so popular of late, are proof 

 of the interest that may be given to a panorama of the world 

 prepared in this way, for the teaching of geography and astron- 

 omy, now too much neglected for the want of such facilities. 



When the plates or callenders are once executed, the printing 

 of these maps will be no more expensive than the ordinary 

 printing of calicos, so that sets of these maps will be brought 

 within the reach of any individual or institution, that can afford 

 the expense of atlases or maps of any kind. Outline maps for 

 the use of schools, printed upon this material without illustration, 

 are already offered for sale by the licensees of the inventor; and 

 also crumb-cloths, table-spreads, and piano-covers, with maps 

 printed on them ; it having been proved that these impressions, 

 with the coloring, are sufficiently durable for these purposes, not 

 excepting carpeting, which is exposed to hard service.

These are printed upon vulcanized India rubber, vellum, dra- 

 pery, and tissue ; drapery being used for pocket maps, and vellum 

 for those that are mounted. The advantages over paper which are
