APPENDIX. 



INDEX TO TREES ABOUT THE CAPITOL, WITH ADVICE TO VISITORS 



INTERESTED IN THEM. 



The interest shown by many visitors in the young growth about the Capitol and 

 the character of the inquiries made by them is a gratifying evidence of the growing 

 preparation of the public mind to give economic forestry its due national importance, 

 and also of a rising disposition to study the choice of trees and methods of using them 

 as aids to public health and comfort, and as means for the decoration of homes and 

 the improvement of scenery. 



As to citizens from all parts of the country and to visitors from abroad the Capitol 

 is often the first and a more continuous attraction than any other in Washington, it 

 is not surprising that its small plantations should receive more than their due share 

 of attention relatively to other expositions of sylviculture near by. It is for this 

 reason desired not only that such information about them as is more commonly wanted 

 may be made readily attainable and that misleading impressions of the purposes they 

 are meant to serve may be guarded against, but that visiters may be advised of 



THE ADVANTAGES OTHERWISE OFFERED IN WASHINGTON FOR THE STUDY AND THE 



ENJOYMENT OF TREES. 



The climate of Washington is subject to great extremes of heat and cold, dampness 

 and dryness, but, for some not clearly established reasons, it seems to admit of an 

 unusual range of vegetation, and allows of the growth in a more or less vigorous or de- 

 pressed way of numerous woody plants not known far to the northward, and of some 

 not common to the southward, except at considerable elevations. It is hospitable, 

 also, to a larger number of foreign trees than the climate of most other parts of the 

 country. 



The Capitol ground is not planted with the least purpose to show what is possible 

 in either respect; the aim in the larger part of it has been to avoid exciting interest 

 through the exhibition of strange qualities in trees, especially of such as might be 

 suggestive of unnatural or forced conditions, or of stratagems of horticulture, nor have 

 the trees to be found in it been given position with a view to conspicuously present- 

 ing their individual qualities; rather, for reasons that will be later given, it has been 

 designed to obscure these. 



But, as visitors to the Capitol often find trees that happen to be new to them, and 

 about which they wish to be better informed, labels have been placed before a large 

 number, giving names under which inquiries can be made. With these as memoranda, 

 and such other facilities as are supplied by the maps and tables herewith, it is hoped 

 that the Capitol ground may «erve to many as an introduction to such better oppor- 

 tunities as are offered in the city, there being few trees within it of which more in- 

 structive, because older, examples are not to be seen near by and better exhibited be- 

 cause planted with the design of exhibition. 



The several government plantations in which they may be looked for are unfortu- 

 nately divided, fragmentary, and, each by itself, incomprehensive and incomplete,
