Ponn.—Analyses of a few of the Fire-clays of Auckland, 351 
ware, and stoneware. The enhanced value in labour would be met by the 
risk, freight, and high rate of duty in importing, and in many places water 
power could be utilized, while at the Waikato, Bay of Islands, and Whare- 
kawa mines, the proximity of coal would be of the greatest value. During 
the year 1878 there was imported into this colony fire-bricks, pipes, earthen- 
ware, and stoneware to the value of £48,900, while in 1874 the same class 
of goods imported were valued at £65,860. 
In conclusion, I hope that greater attention will be given to this 
subject than has hitherto been accorded to it.
