Treat the other ground glass in the same way, and when 

 hard grind the two new ones together with pumice and 

 water until the sections are as thin as possible. Then 

 carefully dissolve them off witli turpentine, and select 

 and mount in balsam. Some will show best as opaque 

 objects. Page 161

 PORTRAITS OF SOUTH SEA ISLANDERS. 



There is nothing that pleases a native more than to make a 

 display of his accoutrements and insignia of rank. The 

 tattoo marks on the face, arms and breast of the New 

 Zealanders indicate the tribe and rank of each person. 

 A high chief is pretty well covered with them all over 

 the upper part of his body. A married woman is 

 tatooed on her chin as well as on breast and arms. 

 These scarifying marks are put on in India ink, under 

 some pointed instrument (formerly flint or bone), beaten 

 into the skin by a light mallet. It is said that 110 per- 

 son can bear the torture of it more than half an hour 

 in a day. Some of these old cannibals must have had 

 quite a foretaste of torment in this life. Page 298

 WHITE TERRACES AND GEYSER, NEW ZEALAND. 



In the central part of the North Island of New Zealand, 

 about 100 miles inland by the road, is the remarkable 

 geyser district which contains the hot lake Rotomahana, 

 on opposite borders of which are the far-famed 

 White and Pink Terraces. In each case, at a height of 

 nearly 100 feet above the lake, there is an enormous 

 fountain of boiling and spouting waters surcharged 

 with silica. Inasmuch as only hot water will hold any 

 of this mineral in solution, it must necessarily be depos- 

 ited as the water cools. This is the cause of the forma- 

 tion of these splendid and spacious steps and basins of 

 silicious sinter. A slight impregnation of iron in the 

 waters of the Pink Terraces gives to them their beauti- 

 fully variegated pinkish tinge. Pages 308 to 312
