During the latter part of February and the entire month of March the 

 entomologist was engaged at 29 Miles, Olaa, Hawaii, superintending the 

 work authorized by the Board and intended to eradicate the fern weevil 

 in that locality. It will be recalled that the work done in January was 

 only calculated to contain the weevil in the original area of infestation 

 and left a considerable XJart of the interior to be cleared and scarified. 

 This had been roughly done earlier but the effort was entirely inade- 

 quate, the principal defects being (1) failure to destroy the fern stumps. 

 (2) to kill the weevils which had fallen to the ground when the ferns 

 were cut, and (3) to treat tree ferns and epyphytic ferns. It was planned 

 on this occasion to clear the area thoroughly and completely of all 

 ferns, so that there would be absolutely no material on which the weevil 

 could live for a considerable period, and to treat the ground cover w^ith 

 poison in such a manner that all straggling weevils would be killed anni 

 the chance of their escape from the area obviated. Opposition was 

 encountered at once in attempting to carry out this plan, the objection 

 to it being that it was too drastic and unnecessarily interfered with the 

 natural rights of property owners on the infested area. The land under 

 the control of the government w^as treated as originally contemplated, 

 although it ruined the koa part, but in dealing with the property owners 

 it was considered necessary to compromise in order to avoid damage 

 suits, and the work on the residence lots was not as complete and thor- 

 ough as it should have been. One of the property owners elected to per- 

 form the Board's requirements personally and in view of the fact that 

 the labor commanded was hardly adequate for the entire job, no objec- 

 tion was interposed, but it was stipulated that the work should be dono 

 satisfactorily and promptly as the law provides. The arrangement has, 

 however, not proved good, as the person has been unable to secure the 

 necessary labor and the work has been delayed. It is expected that by 

 exerting pressure on this delinquent the work can be hurried and tha\ 

 by careful attention the situation can be daily improved and sooner or 

 later mastered. It was impossible to find evidence of any new infesta- 

 tion, which is a fortunate circumstance. 



The actual work performed during this period is as follows: 



Koa grove — Thoroughly cleared and sprayed with arsenite of soda. 



Deyo lot — Thoroughly cleared and sprayed with arsenite of soda in the 

 rear portion. Middle portion sprayed during rainy weather. House lot, 

 sprayed all ferns that could be found, spared all large ferns and flowers. 



Bowman lot — Eeceived the same treatment as the Deyo lot. 



Kennedy lot — ^Sprayed during rainy weather. 



Shipman lot — The area around lava tubes and a part of cow pasture, 

 which Mr. Shipman fenced, was sprayed, partly during rainy weather. 

 The hog pasture has not been sprayed. The house lot and cow pasture 

 mauka of the honse has not been sprayed. The ferns here are very 

 sparse and are being hand-picked as often as convenient. 



English lot — Referred to above. Xot touched, on account of owner's 

 election to treat it himself. 



Respectfully submitted, 



D. T. FULLAWAY, 

 ' Entomologist.
