Mr. Green expressed pleasure that his 

 paper had drawn such useful information 

 as that advanced by Mr. Johnston. The 

 mutton to which he had referred as bein^ 

 purchasable in England at 2^d. came 

 from Xew Zealand, and he had been in- 

 formed that it could be purchased as low- 

 as 2d. 



Mount Elephant. 



Colonel Legge read a paper on "Mount 

 Elephant and its Limestone Beds," and 

 also made reference to the coal obtained 

 in the vicinity. 



The paper -was discussed by Messrs. 

 E. M. Johnston £)nd T. Stephens, after 

 which Colonel Legge replied. 



Eainfall at Great Lake. 



Colonel Legge read a paper, written by 

 himself and Mr. Kingsmill, on "The rain- 

 fall and water supply of the Great L^^.ke.^' 

 The paper stated that the character of 

 the country at the North was totally dif- 

 ferent from that at the South. Atten- 

 tion T^as paid to this feature, owing to 

 the widespread idea that the Great Lake 

 had no feeders, and that the outflow^ 

 through the Shannon at the south end was 

 compensated for by the influence of 

 springs at the bottom of the lake. Ee- 

 ference was made to the extent of the 



rainfall between the south end of the^ 

 lake (Swan Bay) and the Little Lake at 

 the north. The difference in the fall of 

 rain at the two places was caused by the 

 proximity of the north end of the lake 

 to the high mountains of the Western 

 ranges, which caught all the rain coming 

 from the west and north-west. The ex- 

 tent of the fall of rain in various parts 

 of the neighbourhood was explained, and 

 attention "directed to the effect exercised 

 by the adjacent mount-?.ins on the preci- 

 pitation of rain around the head of the 

 lake. It was thought that, though there 

 were no large feeders at the north of the 

 Great Lake, the rivulets that did exist 

 carried a large body of water to the lake 

 after heavy rain, and the climate was so 

 wet that the discharge from the sur- 

 rounding mountains was of frequent oc- 

 currence throughout the year. The con- 

 ditions which affected the water supply of 

 thfe Great Lake were— A wet climate at 

 the north end; a watershed of mountain 

 rivulets ; repeated heavy falls of rain ; 

 melting of snow; the normally small out- 

 flow at the south end. 



Votes of thanks were accorded the 

 writers of papers. 



Discussion of the paper was postponed 

 until next meeting, and His Excellency 

 was accorded a vote of thanks for presid- 



JULY MEETING, 

 Owing to heavy rains the meeting- lapsed.
