feed on wild berries and insects, and iicst zvell up in forest trees. 
This latter fact makes them particularly good subjects for trial 
in the Islands, as they would be largely exempt from attacks by 
the mongoose. 
It is impossible to predict beforehand" the probable results of 
an attempt to establish the foregoing species in the Islands, 
though I see no reason why any of them, except the migratory 
species which are doubtful, may not thrive there. Sometimes, 
however, tw^o or three attempts to establish a species in a foreign 
country have to be made before the bird is finally acclimatized. 
It may be said that the general history of efforts to acclimatize 
birds in foreign parts shows many more failures than successes. 
It has always unfortunately proved easier to secure and import 
the hardy seed eaters, which can be bought in almost any bird 
store, than the more delicately organized insectivores, which ex- 
plains largely why so many disastrous importations have been 
made in different parts of the world. The introduction of really 
useful species, on the other hand, cannot be attempted without 
entailing considerable expense and trouble. Hence the rarity of 
properly conducted experiments. 
Should attempts be made to import into the Islands any birds 
from California, I would suggest that you can probably obtain 
all necessary information as to where they can best be secured 
from Mr. Joseph Grinnell, of the Museum of Vertebrate Zoology, 
University of California, Berkeley. I have no doubt that Miss 
Annie M. Alexander, Oakland, California, through whose gener- 
osity the museum has been established, would take great interest 
in the matter. I shall be glad to supply any further informa- 
tion on the subject or to aid in any way within my power. 
Very truly yours, 
H. W. Henshaw, 
Chief, Biological Survey. 
Correction : In the reports of the Superintendent of Forestry 
on following pages in reference to changes of boundary in the 
Kau, Hawaii, and West Maui Forest Reserves, the table show- 
ing ownership of lands in the Kau Reserve (p. 71), should read 
as follows: Kaalaala-Makakupu Tract, Govt. (Lease No. 555), 
Keaiwa — Hawn. Agricultural Co. 
On West Maui the proposed forest planting is to be done by 
the Wailuku Sugar Co., not by C. Brewer & Co.
