In Figure 2 is exemplified the ordinary unweathered tabular iceberg with 

 freshly fractured cliffs and a level top. Figure 1 represents a smaller example of 

 the same type, with stratification lines, showing how the whole is made up of 

 successive deposits of snow. In Figure 3 a more worn and weathered berg is 

 shown, with many inequalities obscured by snow-drift.
