going strong, with a membership of SO. and an attractive pro- 

 gramme. Mr. B. S. Roach has completed the third of his series 

 of fine articles on the founders of Australian botany ; this 

 article deals in a most complete manner with the life of Ferdi- 

 nand von Mueller, and is written in that intimate and personal 

 manner that characterises Mr. Roach's biographical notes. Dur- 

 ing the past few weeks the Field Naturalises ' Committee, in 

 conjunctioii with the Fauna and Flora Protection Commit te?, 

 took a leading part m organising a i)ublic demonstration ni 

 favour of further setting aside of national reserves, and of a 

 more effective protection of the native animals and plant:; in 

 our present reserves. 



EXCURSIONS AND LECTURES. 



Excursion, April 9, 1921. — The (uiarry on the old road 

 leading to Beiair, from which road metal is now being pro- 

 cured, was visited by a party, with Mr. A. G. Edquist as leader, 

 A shot which had been fired in the morning had brought dov,n a 

 large quantity of rock. This provided a fine field for study, 

 because the broken faces of the stone and the contained minerals 

 were fresh and clean. After the rock had been examined, and 

 its mineral content and physical structure determined, a survey 

 was made of the quarry. The nature of the forces and agents 

 which had produced the metomorphic characters of these ])ar- 

 ticular rocks were discussed in the light of the evidence put 

 forward by modern geologists. 



Excursion, April 23, 1921. — In the absence of Capt. White, 

 Mr. A. G. Edquist led the party, which took the Beach car to 

 Lockleys P.O., and from there proceeded south through a 

 plantation of native trees, which had been planted on an area 

 reserved as a bird sanctuary by Mr. White. Chief among the 

 flora examined were specimens of banksia, hakea, callitris, 

 casuarina, acacias, exocarps, loranthus, exotic pines, many small 

 plants, including hibbertia, and also several species of eucalypts, 

 amongst which was E. cneorifolia from Kangaroo Island. Leav- 

 ing the reserve, the party proceeded to the sandhills behind the 

 rifle range, and there studied the re^nains of native ^^eapons 

 and implements used by the blacks, who had a large encamp- 

 ment at this spot in the early days. The effect of the wind as 

 an eroding agent was studied, and the interesting calcified 

 remains of tree stumps were examined with much interest. 



Excursion, May 9, 1921.— The excursionists journeyed by 

 motor charabanc to Golden Grove, a locality which was visited 

 very early in the section's history, and which has often since 

 been its trysting place. A cool breeze and brilliant sunshine
