Mylarris Beetles. 749 



The foregoing tables show that collecting was a very effective 

 measure in small gardens. The results from the vegetable garden in 

 1918 and from the orchard in 1919 were not quite so good, but, never- 

 theless, were fairly satisfactory. In large fields and orchards the 

 Jesuits are not likely to be always so good as those obtained by the 

 writer; yet, if properly carried out, collecting should prove an 

 effective control measure. 



From five to thirty minutes were required each day for about a 

 week to clear the beetles from a small garden, so it can be seen that 

 controlling the pests in such cases is not a difficult proposition as a 

 rule. In orchards and fields it is a different matter, but our experi- 

 ence is that collecting is quite practicable. It requires a certain 

 amount of labour, but so does every other operation on the farm, and 

 the labour requiied for this work is less than it would appear on 

 first thought. Half a dozen boys working for an hour or two can cover 

 a pretty large area of ground.

Offer of Tractors. 



The Department has received an offer of a number of heavy 

 tractors of the caterpillar type, which were built for war purposes 

 and are now available for disposal. These are of 110 h.p., are petrol- 

 driven, and are capable of exerting a draw bar pull of six tons. The 

 use of petrol as fuel is undoubtedly a great disadvantage under 

 present circumstances. Any one interested in this type of tractor is 

 recommended to apply to the Secretary for Agriculture, Pretoria, for 

 further information.
