The boulder bed is occasionally replaced by a very coarse sand- 

 stone, -which' is seen resting on the gneiss in some places, as to the 

 South-west of Takua on the Tikiria Nullah and to the East of Laija 

 in Eehrakol. In the latter case, the sandstone bed is probably 20 to 30 

 feet in thickness, (the section in the bed of- a small water-course being 

 very imperfect), and above the sandstone the usual boulder bed occurs 

 of considerable thickness, probably not less than 100 feet and exhibiting 

 all its typical peculiarities. In the former case (near Takua) the true 

 boulder bed is absent, but an ordinary conglomerate of quartz or gneiss 

 pebbles appears to replace it, pebbles being rare in the next beds as 

 usually seen. 



The most usual matrix of this boulder bed is a fine bluish sandy and 

 rippled shale.
