UNIVERSITY OF COLORADO STUDIES 



park, fringed by a band of meadow with swamp grass and clumps of 

 willows. A broad area of dry grassland extends back from the creek 

 and this is followed by pine and spruce forests on the surrounding hill- 

 sides. A considerable extent of aspen and alder forest on a moist hill- 

 side opposite the laboratory and a ridge covered with sage brush and 

 various dry-country plants offer extreme conditions for plant growth. 

 Thus in the immediate neighborhood of the laboratory, within twenty 

 minutes' walk, there are almost unrivalled oportunities for ecological 

 study. 



From the standpoint of ornithology and mammalology Boulder Park 

 is not especially rich but there is opportunity here for studying some of 

 the more common birds and mammals of the region. An abundance 

 and variety of insects make it possible for the student to secure a good 

 collection with a minimum amount of exertion. During the summer 

 of 1909 a large number of specimens of insects were taken as well as 

 many birds and some mammals. 



To the student who wishes to become acquainted quickly with exam- 

 ples of many plant families Tolland offers a wealth of material for work. 

 In the early spring season — which is the month of June — there are wil- 

 lows, alders and birches in blossom, and, somewhat later, pines and 

 spruces. Flowering herbs are abundant and varied in character. The 

 growing season is so short that in two months' time it is possible to observe 

 nearly the whole flora from blooming of willows to fruiting of gentians 

 and composites. 



The laboratory is a place where those who wish to become acquainted 

 with the outdoor side of botany and zoology may find instruction suited 

 to their needs. Teachers who wish to prepare themselves for nature- 

 study work may make collections to be used later in their schools. The 

 advanced student, trained in laboratory work, may carry on investigations 

 and enlarge his knowledge of plants and animals in the field. To the 

 high-school or college instructor who wishes to broaden his horizon by 

 intimate contact with nature and an acquaintance with mountain plants 

 and animals opportunity is here given to learn much in a short time. 



The laboratory is in no way a rival of the many excellent seaside and 

 lakeside laboratories in various parts of the world. It occupies a unique
