tained both ripe and unripe infested coffee berries. The crop in 

 general on or near government road was not yet sufficiently ripe 

 for harvesting although there had been some few small i)ickings 

 in many fields. In all the fields there were dropped berries in 

 more or less c|uantities. Owing to heavy rains during visit in 

 Kona I found it impossible to investigate the "Opius" experi- 

 ments. Mr. Wallace, however, assured me that instructions as 

 to placing and taking off the nets on the trees had been com- 

 plied with. As a matter of fact too short a time had elapsed since 

 the liberation of the "Opius" parasites to make it worth while in- 

 vestigating for parasatized larvae. I think, however, that it now 

 would be interesting to secure small quantities of coffee berries 

 from some of the trees in the immediate neighborhood of where 

 these special ])arasites were liberated and to work these out for 

 possible parasites in the insectary. During my visit in Kona I 

 arranged a meeting with Mr. Macfarlane of the Capt. Cook 

 Coffee Company and concluded an arrangement with him where- 

 by he would be willing to defray his portion of the expense in- 

 curred by reason of our having previously bargained with Jap- 

 anese and other planters to each set aside a ^4 ^cre (approxi- 

 mately) of bearing coffee trees wherever the "Opius" parasites 

 had been liberated. Messrs. Hackfeld & Company having already 

 practically agreed to the same course, provided Mr. Macfarlane 

 also concurred, the Board has been saved considerable funds 

 which would otherwise have had to be expended to reimburse the 

 Japanese and others for the crops on the )4 acres referred to. 

 There were five or six of these areas reserved from the present 

 crop pickings, the reservation being allowed for a period of ap- 

 proximately three months.

 Two vials 200 ])arasites liberated in cdw ]>cn at lower end of 

 ranch. Conditions as to future liheralions could be improwd by 

 gathering and ])lacing manure in special enclosure. Present con- 

 ditions not altogether satisfactory because of cattle tramping 

 down the drop])ings in the pen.
