OB4TUARY 



Jt fa with regret that we. inns* record the untimely death of Mr Allan 

 Roderick Henderson, U..M , a member ot our Quh tor some years. 



Of wide cuhn»i\ with many eotmuuniiy interests, the late Mr. Henderson 

 did not participate fully iw Club activities. He occasionally attended CcnOial 

 Meetings however, and, in his leaning*:; towards natural history, evinced a 

 passion tor birds. Ou a memorable Club excursion lo Anglesea a few years 

 Sgb he acted as host and guide at hjs delightfully situated cottage on the 

 foreshore. Some of us were fortunate enough to ubtaiu a gttmgse of a I3rist!e» 

 bird near Ins side verandah, and, later, as we were iiiepanng to leave on the 

 homeward journey, we plainly hctitd and identified the chills of ihc Geclutrir

 rear of the cottage. The vicinity is the type locality of the sub-species

 of SM-birds 



Mr- Henderson maintained a lively concern for National Parks m Viciuria. 

 and was part author of a publication on the subject. Once, upon learning i>f 

 the seclusion and unwitivc nature ot the Lakes National Park at Sperrmvhale 

 Head, he expressed a wish lo see this area, and confirm for himself the 

 statement ihat it embraced at least a thousand acros of tru- indigetUtus Ucath-
