to Mr. Alonsarrat in person what was most desired as to condi- 

 tion of cow droppings, and he promised to get to work on these 

 at once. 



August 11 — Hawaiian Agricultural Co., Pahala, Kau ; W. H. 

 Ogg, manager. One vial, 100 parasites. Upon inspection con- 

 ditions were not found altogether satisfactory in the enclosure 

 selected by Mr. Ogg for liberation of the parasites. I therefore 

 withheld a portion of the parasites intended for that place and 

 distributed them elsewhere. The enclosure is at the corner of a 

 large pasture which cattle frequent daily, j4 i^i^^ cast of the 

 mill near Chinese graveyard. I found much manure piled in the 

 enclosure but as yet no pupae. Suggested that in future manure 

 be spread only 6 inches deep in enclosure and that intervals of a 

 few days take place between each spreading. Mr. Ogg is much 

 interested in the establishment of the parasite and is taking par- 

 ticular pains to arrange conditions properly for future liberations. 

 I would suggest that, at as early a date as possible after due 

 notice from him, we send him a strong colony. I fear that those 

 I liberated there will not multiply satisfactorily as pupae was 

 scarce at the time. The same may be said of the previous lot sent 

 him via Hilo and the Volcano House. These were placed in an 

 open pasture where droppings were more or less tramped down 

 by cattle. 



August 11 — Flutchinson Sugar Plantation Co., Naalehu ; Geo. 

 Gibb, manager. Two vials, 200 parasites. Practically the same 

 conditions applied here as at Pahala. The droppings were un- 

 satisfactory and but few pupae seen. The manager has selected 

 an enclosure in the bullock pen about 1000 feet away from the 

 road leading to manager's house. Water is in close proximity 

 and the adjoining pasture is fairly stocked with cattle. As the 

 manager promised to have gathered a larger quantity of suitable 

 manure and placed in the enclosure I agreed, if possible, to liber- 

 ate parasites there again upon my return trip from Kona. 



August 13 — Received 15 vials, approximately 1500 parasites, 

 at Kealakekua via Kailua per Mauna Loa. 



August 13 — W. H. Greenwell Ranch, Kona. Three vials, 300 

 parasites, were sent by me through one of the Greenwell boys to 

 the Puulehua section of the ranch, ten miles mauka from Keala- 

 kekua, at 4200 feet elevation. Conditions were said to be good 

 up there as to manure because of the dairy, 100 cow^s being 

 milked daily. Besides this the regular range of the ranch is in 

 that section. Upon inspection of the home dairy at the home- 

 stead on the government Kona road I found conditions for 

 liberating altogether unsatisfactory and, as horn fly at the time 

 was not bad anyway in the latter place, I decided to have the 

 parasites liberated in the Puulehua section above referred to. 



August 13 — John Paris Ranch, Kona. Three vials, 300 para- 

 sites, were given by me to Mr. Paris for him to take personally
