Director's Report for 1916. 9 
ance given us by the Museum in the loan of the valuable collection 
of casts and the most generous and helpful assistance of Mr. Stokes 
and Mr. Lambert. These gentlemen who represented you, and 
Mrs. Stokes who gave so freely of her time, inspired the best pos- 
sible work on the part of our Committee, and brought to Maui’s 
careful attention the excellent work of your most valuable Museum. 
I feel that your enthusiastic support of the project on Maui, which 
you know is our first attempt, will materially assist in subsequent 
fairs whether held here or on the otherislands. ‘The Museum can- 
not be thanked enough, and you, kind sir, for the pains taken to 
so materially assist in Maui’s First County Fair. 
In behalf of the Committee of Hawaiian Arts and Crafts, 
I remain most gratefully yours, 
ROWLAND B. DopGE, Chairman. 
Botany. From the Report of the Curator of Botany, Mr. 
Charles N. Forbes, I quote from his field work : 
‘During the latter part of May I made an excursion to Hawaii 
to observe the effects of a lava flow on vegetation. In order to 
obtain quick transportation from Hilo to the source of the flow I 
accepted the invitation of Dr. C. D. Barnes to join his automobile 
party. While an unforeseen illness prevented a thorough explora- 
tion I was enabled to see much which helps to explain conditions 
observed on many old flows. I was able to visit a branch of the 
flow in Kahuku while it was still hot, although movement had 
ceased, and to see the actual source of the flow which was in great 
activity. 
‘“The effect of heat on the lee side of the aa flow visited was 
most interesting. Where the lava overhung dry grass, as it did 
in many places along the flow, the grass was only scorched the 
amount of the overhang away from the flow, which was only six 
inches in many places. Detached pieces of lava which fell off and 
away from the flow simply burned a small circle about themselves. 
Branches of trees actually overhanging the flow were usually but 
not always withered ; while otherwise the tree remained unharmed. 
In one place an ohia (JZetrosideros polymorpha) tree in full bloom 
was nearly surrounded by a wall of lava without its foliage being 
even wilted. Near the end of this flow a large prostrated koa tree 
( Acacia koa) had been carried a short distance without its foliage
