the greatest number of grubs can be destroyed by its use, and from 

 40 per cent, to 50 per cent, of codlin larvae are said to have thus been 

 entrapped. The bandages are made of wide bands of Hessian, 

 about 12 inches wide, and long enough to encircle the stem of the 

 tree. The piece of stuff is folded in the middle and fastened tightly 

 round the tree by means of twine. 



"According to the regulations at present in force in Tasmania, 

 the bandages should be placed on the trees in November, and 

 finally taken off not later than the following July." They should 

 be removed every eight or ten days and boiled this boiling also 

 destroys a great many eggs of red spiders and then replaced. 

 This is preferable and more reliable than an eye inspection of the 

 bands, whereby a certain number of grubs are generally allowed to 

 escape unnoticed. On going over the trees, when the bandages are 

 removed, a pointed probe should be used to search out all grubs 

 which may have secreted themselves under pieces of bark, or eaten 

 for themselves a hiding-place into the bark, broken branches, forks 

 of the limbs, or old scars as they prefer such places to the bands. 

 Two bands, one over the other, are sometimes used, as some of the 

 grubs, at times, crawl over the first in search of a hiding-place 

 more to their liking. " For a considerable number of trees 

 examined," says Lea, "I found that where the trees had been 

 properly bandaged, four grubs would be found in the bandages to 

 one in the bark beneath them ; doubtless in the rougher- barked 

 trees many of the grubs never came as far as the bandages, and, in 

 many instances, more grubs will be found in the bark than in the 

 bands, especially if these cross an old saw-scar." These bands 

 answer a good purpose, but some growers successfully supplement 

 them by placing among the lower limbs and on the ground around the 

 trees, other traps, made of sandwiching a piece of sacking between 

 two shingles, and joining these together with a nail. These traps 

 are easily made and laid, and as easily gathered up and inspected. 



Although bands answer a good purpose, they must be applied 

 to other kinds of trees, and even to fencing posts around the apple, 

 pear and quince trees, to do all the good which may be expected 

 from them. 



Mr. G-eorge Compere, who has done valuable work in Australia 

 and China for the State Board of Horticulture of California, and 

 who is now attached to this Department, mentions another easy 

 way of gathering and destroying the codlin grub in California. 

 Long straw is lightly scattered about the trees in the summer, and 

 then raked up into small heaps and set fire to.

' 12. Probably the greatest distributor of the codlin moth is the 

 fruit-grower himself, and the compulsory spraying and bandaging 

 in force in Tasmania meet with many opponents, says Lea.
