In an orchard oii Pioneer River a persimmon tree had many 

 dead beetles under it for past two years. The leaves were much 

 eaten, and the ground was white with the corpses of the beetles. 

 Beetles confined after feeding on this tree soon died, while some 

 from a fig lived for a considerable period. See also Editorial, 

 p. 244.

In the Childors district about 30,000 acres of scrub were 

 felled during the preceding ten or twelve years, with a marked 

 decrease in the pest. Thorough cultivation destroys grubs. £300 

 to £400 spent for collecting beetles in 1898.

' ' The grub originates in the blady-grass country — i.e. the 

 forest country, ' ' but congregates on scrub timber to feed. After 

 destroying four tons of beetles on their estate in 1894, the cane 

 was ruined the next year just the same. Many of the principal 

 feeding-trees were removed, though Mr. Paget did not consider 

 that this was responsible for the disappearance of the beetles. 

 In 1899 the cane was free of them.

In the Proserpine district, bandicoots were plentiful and 

 grubs scarce. They go after the grubs. The birds, also, destroy 

 an enormous quantity of grubs and should be protected. Much 

 of the trouble probably was due to the destruction of birds by 

 the kanakas.

Mr. Swayne stated that it had been 25 years since the 

 grubs first appeared in the Mackay district, and in 1891-2 their 

 numbers were so great that they threatened the stoppage of the 

 industry. During 1895 the Agricultural Department voted £1,500 

 to assist in their destruction. From 1896 to 1899 they collected 

 50i tons of beetles at an expense of £2,649 19s. 7d'. Levy 6d. 

 per acre; and 6d. per lb. was paid for beetles.
