 — especially to one who has experienced the conditions of their 

 formation. These Kilauean pisolites are large, often exceed-

Scattered about upon these fields of ash, and even to a con-

 and Keanakakoi, one may see a great quantity of angular blocks 

 of lava rock, ejected in that condition, and also many true
