Islands. As it requires more moisture and better land than sisal 

 I doubt if it will be as profitable as that plant. 



Quite an importation of choice California grape vines was 

 made by Mr. Isoshima to be planted at Wahiawa ; no insects were 

 found, but in order to be safe we niake a practice of fumigating 

 all grape vine stock wath carbon-bisulphide, so that vapor was 

 adnunistered to this importation. 



Several colonies of lantana destroying insects have been sent 

 out. 



Mr. Muir, beneficial insect collector of the Hawaiian Sugar 

 Planters' Association, sent from Fiji a colony of a large "lady- 

 birds {SynoncJie sp.). They were placed in charge of Mr. 

 Kotinsky, and Miss E. Dayton attends daily to feeding them with 

 aphis, which they greedily devour. They are breeding freely, 

 having passed through the various stages from ^gg to pupae and 

 as soon as we have native-raised adults will liberate them out of 

 doors. 



Mr. Kotinsky and I have twice visited the district where it w^as 

 reported that a borer w^as at w^ork destroying the young living 

 branches of the Algeroba trees ; we made a careful examination 

 but failed to discover any borers. The gentleman showed us 

 wdiere he cut the branch, but we could not find any insect. In a 

 near by wood shed we examined the algeroba wood wdiere we 

 found one native borer, species of Bostrichid, just entering a stick 

 of wood. This beetle only attacks w-ood that is beginning to sour 

 after cutting, so I don't look for it ever becoming a pest in grow- 

 ing trees. 



On February 27th the S. S. "Nippon Maru" brought a large 

 shipment of grape cuttings for the Federal Experiment Station 

 from the San Joaquin \'alley, California, which we took the pre- 

 caution to fumigate, as they were from a district that is known 

 to be infested with the ''grape vine hopper" (Erythroneura vifis) . 

 This is a very serious pest and breeds rapidly and hibernates in the 

 perfect state so the fumigation would reach any that would have 

 been present on the cuttings. 



Mr. Hughes, the Master Car Builder of the Oahu R. R. Co., re- 

 ported to me the existence of a serious pest attacking the hard 

 wood timbers and finishings of some of their passenger cars. On 

 the 6th inst. Mr. Austin and I visited the car department and 

 found the pest to be Termites, and I prescribed the injection of 

 carbon bisulphide into the infested parts, also gave them the in-
