The convention lasted six days and was attended by over 

 sixty Supervisors and officers of the National Forests of 

 Colorado, Wyoming, South Dakota, Michigan, Minnesota, 

 and Nebraska. Twenty-nine National Forests were repre- 

 sented, and a wide range of topics closely related to the 

 upbuilding of the West discussed. District Forester Smith 

 Riley presided at the meetings, and each day was given 

 over to the consideration of some particular branch of 

 National Forest work, such as good roads and their 

 relation to State and community development; organi- 

 zation and up-to-date business methods; opportunities 

 for public service and educational problems for Forest 

 Service men, etc. 



Lectures on organization and efficiency were delivered 

 by the manager of the Ford Motor Company's plant in 

 Denver, the superintendent of the Mountain States' 

 Telegraph and Telephone Company and the efficiency 

 engineer of the Denver Tramway Company. Good 

 roads problems were presented by officers of the Bureau 

 of Public Roads, United States Department of Agricult- 

 ure, and the subject of game conservation dealt with by 

 the director of the Colorado Museum of Natural His- 

 tory. Other interesting papers were delivered by mem- 

 bers of the Colorado Mountain Club and officers of the 

 Boy Scouts' organizations. 



The possibilities for the development of the National 

 Forests as great recreation centers ; for the use of the poor 

 man as well as the rich, was one of the paramount topics 



of the convention. Figures were presented showing that 

 the Forests of District 2 had over 667,000 visitors in 1916 

 and of that number the seventeen Forests of Colorado con- 

 tributed over 600,000 visitors. 



On one day of the convention the Supervisors made a 

 special trip to Fort Collins as guests of the Colorado State 

 Agriculture College. After inspecting the experiment sta- 

 tion the men attended a series of lectures on various sub- 

 jects connected with the grazing of livestock on the Na- 

 tional Forests, delivered by members of the College faculty. 

 The program concluded with a banquet in the evening. 



During the convention in Denver the "get-together" 

 spirit was fostered by a series of dinners at which promi- 

 nent speakers addressed the Supervisors, and by social 

 dances and theatre parties. At the close of the meetings 

 resolutions were adopted commending and supporting 

 the work and administration of H. S. Graves, Forester of 

 the United States Department of Agriculture and Smith 

 Riley, District Forester. 



rPHE shortage of labor in the lumber industry is being 

 A felt even in the government operations on the Menom- 

 inee Indian reservation at Neopit, Wisconsin. The super- 

 visor, A. S. Nicholson, is having difficulty in finding two 

 hemlock inspectors and a yard superintendent. 



ILLUSTRATED GLOSSARY FURTHER DESCRIPTIONS OF ROOTS 



Figure 41, the rootstock of the peppermint; this is nothing more than an 

 underground creeping stem. Such rhizomas, as they are called by botanists, 

 are more generally known as running, creeping or scaly roots. From their manner 

 of growth and structure of their stems, it is clear that they are subterranean 

 branches, having joints or nodes with axillary buds at their points of union, 

 with other evidences of branch structure. Such underground stems are extremely 

 difficult to get rid of, and are therefore of great annoyance to the agriculturist 

 and farmer. 



Figure 42 illustrates the nature of a tuber, and shows the subterranean 

 growth of the common Irish Potato, which gives every stage of an ordinary 

 tuber. The eyes of the potato are merely axillary buds, and one of these is 

 shown on section in Figure 43. 



Corms, or solid bulbs have already been briefly touched upon and illustrated. 



Another form of the corm is seen in the bulb, though the two plans of growth 

 merge into each other. When perfectly typical, however, they are such growths 

 as we see in the Canada Lily (Figure 44), shown on section in Figure 45. The 

 thickened scales there shown are bases of leaves which are loaded with nourish- 

 ment for the plant. There are hundreds of examples of such growths to be 

 studied, being duplicated many times in fleshy plants. 



Parasitic plants like the mistletoe grow upon other plants, and their roots 

 draw sustenance from them. This, however, is not the case with certain air- 

 plants or Epiphytes, for these live entirely upon what they get from the air. 

 Two species of them are shown in Figure 46, the one with the flowers being the 

 Epidendrum conopseum, and the other the "Black Moss" (Tillandsia usne- 

 oides); both are from our Southern States, and are very instructive plants to 

 study.
