ECOLOGICAL NOTES I15 
which runs through the gulch, is 6,923 feet above sea level at the place 
studied. The hills at the side are about sixty feet higher. A west and 
east line from the top of one hill down through the gulch and up the 
other side was laid off with stakes every twenty feet. Every plant 
along this line was recorded and its exact position noted in feet and 
inches from the preceding stake. This record shows very well the relative 
abundance of the plants which occur here; while the number of plants 
found in any of the twenty-foot distances shows the relative closeness or 
openness of the formation. A few sample records only are given below. 
Between Stake 1 and Stake 2 the ground slopes gently to the east. 
Here 52 plants were touched by the tape-line stretched between the 
stakes. As most of the plants were not in flower they could not be 
identified fully but the list will serve the purpose intended, viz., to show 
the general character of the vegetation with reference to slope, altitude 
(which here means moisture), character of soil, etc.
