as it was ground fell upon a flat rock in front of the cleft. It 

 resembled, viewed from above, a primitive grindstone. The 

 nardoo was poured down the cleft, and was crushed between the 

 wheel (turned by hand) and the two rollers. This is the descrip- 

 tion of the modus operandi as given to Mr. Norman Grant, Dist. 

 Engineer for Roads and Bridges, by the licensee of East Toorale 

 Hotel, who found it in situ. The flat rock and the mechanism of 

 the two cylinders had been injured by a bush fire; and it is very 

 much to be regretted that the discoverer did not bring away the 

 rollers. I hope some day to be able to visit the place myself and 

 be able to make a sketch of the ground. As far as I have 

 been able to learn, this is the only mill partaking of the nature 

 of machinery, made by natives, yet discovered. Mr. Norman 

 Grant kindly presented me with the stone in 1897, knowing the 

 interest I take in the ethnology of this country.

 when young by the attacks of an Aphis. Also specimens of the

 Meeting; and a collection of individuals of Icerya purqhasi, from 

 which a number of the useful lactybird beetles Novitis cardinalis 

 had bred out.
