formation. Then later, when the origin of the graded surface is deter- 

 mined, the appropriate genetic term may be applied. 



The following terms were discussed, with references showing their uses 

 by various writers : Terrace, grade, slope, bench, grade-level, grade-plain, 

 peneplain, base-level, and bevel. 



The conclusion was reached that some compromise must be made by 

 physiographic writers in order to secure uniformity of usage. The choice 

 would seem to lie between terrace, grade-level, grade-plain, and bevel. 

 If one of these terms could be agreed upon by physiographic writers to 

 use as a general form term, to imply no genetic hypothesis, greater clear- 

 ness would result.
