The Plant World. 



Boulder, Colo., have made this an integral part of the University, 

 and students who pursue courses in the mountain laboratory 

 receive the same credit for work accomplished as if done in the 

 laboratories on the campus. The six weeks' summer session 

 of 1909 begins June 15, but the laboratory will be open through 

 the months of June and July. 



The location which has been selected is an ideal one. The 

 place is called Tolland. It is a mountain hamlet of half a hun- 



Fig. 2. — South Boulder Park. The Park is a glacial valley converted by stream erosion and in-filling 

 into a flat, plain-like area. Morainal hummocky topography occurs toward the lower end of the valley. 

 South Boulder Creek, which is a r ashing stream a few miles west of Tolland, is here seen to be winding 

 its way through the Par ; clu nos of willows border the stream. A portion of Tolland is seen at the 

 right. The body of water is Park Lake. The hills on both sides of the valley are covered with coni- 

 ferous forests. , 



dred houses about forty miles northwest of Denver and eighteen 

 miles in a direct line from Boulder. The town lies nestled at 

 the base of a high mountain in a small valley, through which 

 flaws a trout- illed stream named South Boulder Creek.
