ABSTRACT OF PROCEEDINGS. XXXIX. 



ever, several species of scrub ticks, and his investigations 

 had fixed the identity of a certain species responsible for 

 a particular form of paralysis. He had also established 

 the period of incubation elapsing between the attack by the 

 tick and the development of paralysis. He had proved 

 that a single tick of the species Ixodes holocyclus was 

 sufficient to set up a train of symptoms closely resembling 

 intoxication, and often resulting in death. The popular 

 idea that symptoms of paralysis appeared in a day or so 

 after infestation was incorrect, as it took 5-7 days for the 

 symptoms to manifest themselves. The question as to 

 whether the condition was due to a living organism or 

 virus, or to a toxin or venom, had not been determined. 



Monthly Meeting, 9th August, 1920. 



Sir Joseph Oarruthers in the Ohair. 



A discussion took place on "Stud Seed Production." Sir 

 Joseph Oarruthers, Mr. W. Birks, and Hon. Secretary, 

 pointed out the valuable work done in this connection in 

 Canada, Sweden and Denmark. In both Sweden and Canada 

 there existed Seed Companies who procured the foundation 

 stocks of the best seed from the Agricultural Departments 

 and extended the sowing of such seed on a large commercial 

 scale. The New South Wales Agricultural Department 

 had commenced to induce farmers to take up the matter 

 of stud-seed production. 



Mr. J. W. Matthews delivered a lecture on " Wool Pro- 

 duction." He pointed out that with improved methods of 

 breeding in 1918-19 with 25,000,000 less sheep there were 

 70,000,000 lbs. more wool produced than in 1891. He 

 demonstrated that, although closer settlement should be 

 encouraged, merino breeding which required large areas, 

 should be safeguarded. The Border Leicester x Merino 

 had proved the best cross for mixed-farming areas.
