of the lawn sprinklers. In front of the 
house where | resided was a lawn of con- 
siderable dimensions upon which a sprink- 
ler was usually kept running. this spray 
of cold water was a delight to all the Hum- 
mers in that vicinity. They would gather 
about it, sometimes three or four together, 
and dart to and fro in the sprav, accom- 
panying their movements with a creaking 
sound that constitutes their song, and 
seemingly in the very height of joy. After 
moving in this manner a few times one 
would dart off toa twig where it would 
light and preen its plumage, or else dash 
after a companion and both would scurry 
away out of sight only to retura again in 
a few minutes to renew their sport. The 
Allen. Alexander, Rufous, Costa, and 
Anna Humming-birds were oDserved to 
bath in this manner at the spray of the 
lawn sprinkler.

ROGUE RIVER RELICS. 
Those who delight in the search for 
hidden treasures left by the aborigines of 
the Pacific Coast will find a fine field in 
Jackson County, Southern ‘Oregon. A 
few years ago, while on a hunting trip, | 
stopped over at the ranch of Mr. Jackson, 
about 10 miles east of Centrai Point. In 
passing over the plowed fields I saw 
traces of former Indian occupation, there 
being flint and chert chips in abundance 
lying about, showing conclusively that 
the manufacture of flint and stone imple- 
ments had been carried on there to a con- 
siderable extent. This induced me to put 
in a spare hour in search of relics to add to 
my cabinet. My search was amply re- 
warded. My first find was a piece of 
sandstone about 7 inches long, 1’%xi in. 
square, slightly tapering at the ends, with 
a narrow groove running lengthwise 
across one side. As the depth of the 
groove was about the dimensions to ad- 
mit an arrow shaft, it was probably used 
for truing and smoothing in their manu- 
facture, the roughness and sandy charac- 
acter of the stone acting as sandpaper or 
emery on the wood (Fig. 1). A very

finds. It was originally a water-worn 
pebble, and is about 1% in. high and 2 In. 
across, dug out to a depth of about 1 in. 
It was probably used for mixing pigments 
of medicinal herbs. My third tind of in- 
terest was a pip2 (Fig. 3), of brown stone,
