ence, the best way to use this material. There are doubt- 

 less many other landscape-gardening problems to be solved 

 and other kinds of grounds to be laid out than those indi- 

 cated in these chapters, but I think, however, that a num- 

 ber of the most constantly recurring ones have been fairly 

 considered. 



Before concluding this introduction I desire to express 

 my obligation for assistance in preparing these chapters to 

 Mr^ Calvert Vaux, Landscape Architect of the Department 

 of Public Parks, New York, to Mr. George C. Woolson, 

 Superintending Gardener of the Park Department, and to 

 Mr. J. Francois Huss, General Foreman of Construction 

 Work in the Park Department. 



In the preparation of the illustrations I am greatly in- 

 debted to Mr. Paul Dana, Commissioner of the Department 

 of Public Parks, New York, for the loan and reproduction 

 of seven excellent photographs, taken by himself, from the 

 unsurpassed tree specimens growing on his father's, Mr. 

 Charles A. Dana's, great country-place at Dosoris, L. I. 

 An excellent photograph of an island in the lake. Central 

 Park, New York, is also reproduced with the permission of 

 Dr. E. P. Fowler.
