THE TREE DOCTOR 



flower-pot, say six inches, put gravel in the bottom raising it 

 high enough so that you can stand the four-inch one (having the 

 plant) right in the center and bringing the top on a level with 

 the outer one, and then fill the space between the outer and in- 

 ner crocks with sand, your plant, thus treated, will do at least 

 five hundred per cent, better than those that are left in the ordi- 

 nary way. Certainly there is more pleasure with one good plant 

 than a dozen half-dead ones. 



New York City imagine they have a superb collection of 

 plants in their conservatory at the Bronx Park; but the Phipps 

 Conservatory in Shenley Park, Pittsburg, or, rather, the plants 

 therein, are an hundred per cent, ahead of those of the Bronx. 

 It would be difficult, indeed, to surpass the quality of the Pitts- 

 burg plants, or the skill displayed in their management. Photo
