The charges for the work since leaving Wellington have been 

 made with a view to cover the actual costs, disregarding wear and 

 tear to the outfit and the time lost in moving about. These chargf s 

 in general have been 6d. for trees under eight feet in height, and Is. 

 for ti:ose above. The increased charges were necessary to keep up 

 the work, as the funds were nearing exhaustion, but they appear to 

 have proved an advantage in other respects. The work has been 

 more appreciated, and every assistance given to facilitate it, no 

 trouble at all being made about the conveyance of the equipment, 

 however great the distance. 



The movements of the outfit have been advertised from time to 

 time in the newspapers, and the public have been invited to be 

 present at stated times in the different towns when full explanations 

 of the process have been given by the foreman. 



Object of this Report. This report is written at the request 

 of the Board to supplement the field work by giving full particulars 

 of the process and of the equipment ; and to point the way for 

 others to take up the work where the Board leaves it. 



The object-lesson of the efficacy of fumigation is now before the 

 public. An inspection of the trees shows them to have improved 

 wonderfully since the treatment, and farmers are enthusiastic over 

 the results. The Board's field work is finished. There are many 

 disadvantages in carrying on a work of this kind through the 

 Grovernment or body like tne Horticultural Board, and now that 

 several thousand trees have been successfully treated, there is no 

 longer any reason for the Board to continue the work. ^N"ot every 

 day is suitable for fumigating trees, but as the foreman and his men 

 were working away from home, they had to be paid for days when 

 no work was done equally with those when they were employed. 

 This loss of time greatly augmented the expense, but is a factor 

 which would be largely obviated if the work was done by the 

 farmers themselves, or by a local party with other employment for 

 himself and men when fumigation could not be carried on to 

 advantage. 



Acknowledgments. As stated in the introductory paragraph, 

 we are following Calif ornian precedents. The outfit employed by 

 the Board was modelled after those employed by the Los Angeles 

 County Horticultural Commission as described in California!! 

 publications; other details were furnished by Horticultural Corn- 

 mi- siojier John Scott, of the same couuty, in correspondence with 

 the Entomologist. The full-page illustrations were purchased from 

 the Calif ornian State Board of Horticulture; they were engraved 

 from photographs of the Los Angeles County Horticultural Commis- 

 sion's outfit. The illustrations of the red and other scale insects 

 were obtained from the United States Department of Agriculture, 

 through the kindness of Dr. L. 0. Howard, the Entomologist of the 

 Department.
