ber of the society. 
Reports from the directors of the several sections were then 
heard, after which those present listened with much interest to 
a paper entitled ''Dakota Indian Mounds," by Lee R. Whitney. 
Mr. Whitney in the fall of 1899 had taken advantage of a visit 
to Ransom county in N. Dakota to dig into a series of mounds

Messrs. Geo. A. West and Chas. E. Brown took part in the

The secretary was instructed to convey the thanks of the 
society to the retiring officers Dr. Peckham and Mr. F. Meinecke 
for their efficient services during the year that was past, after 
which there being no further business to transact the meeting was 
adjourned.

With moisture and light he was most concerned. The first how-
