46 THE CULTIVATED EVERGREENS 



New York by the late Charles A. Dana about fifty years ago, 

 and was maintained for many years in excellent cultural 

 condition. Mr. Dana loved them most intensely. Perhaps the 

 most notable private pinetum in this country at the present 

 time is on the Hunnewell Estate, Wellesley, Massachusetts, 

 which had its beginning between sixty and seventy years ago, 

 by the late H. H. Hunnewell, and is still well maintained. 

 Many of the conifers have attained large adult size and are in 

 excellent health. 



The largest public collection of conifers in this country is 

 the pinetum at the Arnold Arboretum, Jamaica Plain, Mas- 

 sachusetts, where all of the known hardy species of the northern 

 hemisphere, and all of the available horticultural forms are 

 assembled. It affords an excellent opportunity for the gardener, 

 horticulturist, and landscape-gardener to study the particular 

 forms they have in mind for special purposes. The next 

 largest public collection of conifers is in the Arboretum of 

 Highland Park, Rochester, New York. The planting of the 

 nucleus of this collection was in the spring of 1896, and many 

 of the conifers put out at that time have reached a height of 

 thirty-five to forty-four feet. 



Pines. 



It is fortunate that the white pine, Pinus Strohus, one of 

 the most beautiful of all conifers native as far north as New- 

 foundland, is so well adapted to cultural conditions. In very 

 exposed situations the white pine may become partly browned 

 from the sweep of cold penetrating winds. Nevertheless, it 

 makes a noble windbreak when planted rather closely as the 

 trees give mutual support to each other. The plants may be 

 set seven to eight feet apart and when they begin to crowd 

 they should be thinned out and planted elsewhere. The white
