SUGGESTIONS 



RELATIVE TO AN 



ETH^^OLOGIGAL MAP OF NORTH AMERICA, 



3G by 44 INCHES. 



BY LEWIS H. MORGAN, OF ROCHESTER, N. Y. 



It should show — 



I. Ocean boundaries: with the straits of Behring, the Aleutian 

 islands, and the direction of the North Atlantic ocean currents. 



II. River sj^stem, with the small tributaries complete. 



III. Mountain ranges: to be indicated strongly. 1. Great ranges: 

 these to be named; whether wooded or sterile, to be shown. 2. Cross 

 or transverse ranges ; the same. 



IV. Profiles showing the elevations of the continent on every fifth 

 parallel: to be drawn on the parallels, as now shown on the Smith- 

 sonian map. 



V. Prairie and forest areas: 1. Arable prairie; to be shown as on 

 Smithsonian map in Patent Office report, but with a further discrimi- 

 nation as follows: where there is a mixture of forest and prairie, as is 

 the case particularly east of the Mississippi, if the forest predomi- 

 nates use one indication ; if the prairie predominates use another. 

 2. Dry prairie; to be shown as on the Smithsonian map. 



VI. Show the limits of the Colorado desert or basin, as far as they 

 are known. 



VII. Show the barren grounds west of Hudson bay. 

 Vni. Isothermal lines. 



IX. Amount of annual precipitation in figures, for the purpose of 

 showing the comparative wetness or dryness of different areas — no 

 shading. 



X. Boundary lines of States and Territories, with the initials of 

 each. 



XI. Location and distribution of the embankments and eathworks 

 of the mound builders. 



When the map is thus far completed by a draughtsman, there may 

 be added as follows: 



XII. Boundaries of the territories of the several stock Indian fam- 

 ilies, each one to be shaded with a different color: 1. Stock families. 

 2. Nations constituting each family, and their location. 3. Location 

 of principal villages or settlements. 4. Geographical Indian names 

 of rivers, lakes, and localities, &c. 



XIII. Date of map: 1. East of the Mississippi and the Red River
