Interesting results of the work are the finding of the existence 
of totemic clans among the Indians of the Chumashan stock and 
the determination of the genetic relationship of Chumashan and 
Yuman. 
EXPERIMENTAL FLIGHTS WITH THE ORIGINAL LANGLEY 
AERODROME 
The trial flights with the original Langley aerodrome (built 1898- 
1903), which were begun in May, 1914, under the direction of Mr. 
Glenn Curtiss, to determine whether the machine was fundamentally

correct in design and construction, were continued in 1915 at Lake 
Keuka, New York. 
Toward the end of February, 1915, the machine was mounted 
on three elastic skates preparatory to launching it from the ice on 
Lake Keuka, with its original motor and as nearly as possible in its 
original condition. When thus assembled for flight it weighed 
without pilot 955 pounds, including five gallons of gasoline and the 
necessary oil and water. The aeroplane frame and wings were on 
March 2 taken on a tug boat 12 miles down Lake Keuka to where 
the ice was thick, and placed upon the ice under the brow of a wooded 
hill whose shelter made it easier to wing and unwing the machine 
in the wind.
