proposed to discuss, as well as the Glass House Mountains them- 

 selves, that portion of the East Moreton District in which they 

 are situated. It comprises the parishes of Beerwah, Toorbul, 

 Canning and Durundur, a few features of some other neighl^our- 

 ing parishes being also touched upon. 



The Glass House Mountains were discovered and named by 

 Captain Cook in May, 1770,^ and again noticed by Flinders in 

 July, 1802.1 They owe their name to their resemblance to glass 

 houses, when viewed from Moreton Bay on a fine day after a 

 shower. No one has so far ever made a systematic geological 

 examination of them, our knowledge up to the present being 

 derived from scattered notes of various geologists who rapidly 

 toured the district. In the present paper I propose to give the 

 results of over three weeks' field work in the mountains themselves, 

 supplemented by a considerable amount of petrological work on 

 the specimens collected, carried out in the geological laboratory 

 of the University of Sydney. Having been a resident of Cabool- 

 ture, near the Glass House Mountains, for ten yeais, I have had 

 the additional advantage of being thoroughly acquainted with 

 the entire district. 



ii. Bibliography. 



The first geological record of the Glass House Mountains is 

 that of Mr. Stutchbury, who, in 1854, described them as consist- 

 ing of masses of metamorphic sandstone, left standing after the 

 unaltered sandstone had been removed by denudation. | 



In 1875, the Hon. A. C. Gregory referred to them as ^' out- 

 hni'sts of ijo^yhyry. "§
