540 AMERICAN FORESTRY 



specimens, cvpress knees, enormous burls, and samples of special uses of 

 trees such as ship-knees. It is equipped with the necessary apparatus for 

 sectioninf;: and mascerating specimens, with compound microscopes and large 

 charts illustrating sections of various woods. Each student is assigned a 

 locker where his individual assortment of woods may be kept unmolested. 



For use in dendrology there are three separate working collections ; seeds, 

 cones and a leaf and twig herbarium. The seed collection contains samples 

 of about two hundred species, nearly a third of which are conifers. The seeds 

 are kept in screw-top glass jars containing on an average a half-pint of each 

 kind. The cone collection is kept in herbarium cases fitted with drawers of 

 two sizes. It contains from twenty-five to several hundred cones each of over 

 seventy-five species. These collections are for the use of the student who is 

 required to dissect and study both seeds and cones. The leaf and twig herba- 

 rium is also a working collection, and is quite independent of the large 

 botanical herbarium mentioned above. It contains mounted specimens, about 

 fifteen to twenty each, of the more important trees of the United States. Over 

 two hundred species are represented. 



A collection of about one hundred fungi important to the forester is 

 made available for study in forest mycology by allotting species to drawers 

 similar to those used for the cones. Here wherever possible a section of the 

 wood and bark accompanies the fruiting body. 



Exhibits of logging and saw-mill tools, samples of the results of many 

 methods of close utilization of woods, stereopticon slides and enlarged photo- 

 graphs are used to illustrate lectures on logging, lumbering and methods of 

 manufacturing forest products. 



For use in forest mensuration, laboratory and field, an assortment of 

 instruments for both accurate and rough work is provided. Included in this 

 are instruments for mapping and for measuring heights, diameters, and 

 volumes of logs and trees. They are of various makes and patterns giving the 

 student a chance to compare the merits of one with the other. About forty 

 complete stem-analysis sections are provided for volume and growth studies. 



In order to show the difference between seedlings grown in various regions 

 and between different grades in the same region, several hundred specimens 

 have been mounted on herbarium sheets and these filed in cases where they 

 are readily available. Two hundred and fifty stereopticon slides are used 

 to supplement the lectures on nursery w^ork and planting. 



The post-graduate year demands original work in at least two courses. 

 To this end, a research room is well equipped with the apparatus and materials 

 that are needed. The Botanical Library, which is one of the very few complete 

 technical libraries of this kind in the United States, is open to the post- 

 graduate. The Forestry Library contains a complete set of all the Forest 

 Service publications, card-indexed according to subject-matter, many English, 

 German, and French volumes on Forestry subjects, a set of files containing 

 several thousand bulletins, circulars, and clippings from lumber and forestry 

 journals. All of the material in the library is made usuable by means of the 

 card index system. The subjects are listed in a very simple way so that every 

 item is available to the student and can be obtained at a moment's notice. 



For experimental field work the department has fifty acres of plantations 

 of various species growing under many conditions. A one acre nursery is 

 provided with water system and with concrete seed-beds for special lines of 

 experimental work. The university is located only a few hours' ride from 

 the Government Nursery at Halsey, Nebraska, where the students may have 

 an oi)portunity of inspecting tree-growing under very exacting conditions. 

 Every two years the upper classes spend three or four weeks in northern
