also equally determined in their exertions to suppress this pest. 

 One careless and slovenly gardener will afford a breeding ground 

 for this creature, whence its progeny will carry devastation into 

 the orchards of his neighbours. 



Mr. F. Abbott, Superintendent of the Botanic Gardens, said : — 

 With reference to this moth I would offer a few remarks, 

 with a view to disseminating information not readily accessible to 

 many readers. The moth has been so long known that the details 

 of its operations may be found in any work on gardening or 

 horticulture, and it will not be necessary for me to repeat them 

 here, but there are some points on which a difference of opinion 

 exists, that it would be well to call attention to, with a view to 

 having them cleared up. The first and most important is the belief 

 held by many that there are more than one generation of the 

 moth during the season ; the basis of any operations conducted 

 for the suppression of this pest wUl be materially affected by the 

 truth or otherwise of this statement. The following extract from 

 Mackintosh's Book of the Garden, Vol. II. , p. 345, may assist in 

 throwing some light on the subject. After describing the moth, he 

 goes on'to state that it 'invariably selects the finest apple in which 

 to lay its eggs, knowing instinctively that these will be most 

 palatable to its future progeny. (In Tasmania the Golden Harvey 

 is most affected). In favourable weather the little grubs are 

 hatched in a few days, so that in May apples and pears may be 

 found infested by them. At first the grub is white, with a black 

 head and collar, and black slanting double dots which run in four 

 rows from the head to the abdomen, it afterwards becomes more of 

 a flesh colour, the head and collar turning brown, the dots grey 

 and indistinct. It is fully grown in 3 or 4 weeks as its food 

 never fails. It now leaves the fruit, whether it is hanging on the 

 tree or has fallen off, and selects for itself a secure place on the 

 stem of the tree to spin its cocoon and become a pupa. It usually 

 chooses the rents and seams of the loose bark, hollows itself out a 

 chamber, and spins a white web over itself, intermixing some of the 

 loose bark with it. The little grub becomes a pupa immediately in 

 the web, and in a few days the moth comes out, which shortly 

 afterwards pairs and deposits eggs on the fruit. In this way in 

 July and August and partly in September, much sound fruit will 

 again be pierced and infested with the caterpillar of this moth, 

 which are then numerous in proportion to the number of eggs of the 

 first generation which were laid and hatched in May. In the year 

 1822 which was warm and dry, more than the half, particularly of 

 the choice fruit was grub eaten, and moths were still seen laying 

 their eggs till the end of September. Fortunately the caterpillars 

 which are so late in laying their eggs seldom arrive at maturity, as 

 the fruit is taken off the tree at that time." If the above extract 

 states the case correctly it unquestionably shows that there is more 

 than one generation of the moth during the season. The following 

 from Johnson's Gardener, Vol. III., p. 103, Book II. — "Apples" — in 

 part bears out the statement as it shows that in some cases if not in 

 all the larvse remains in the pupa state for a short time only. After
