form of park tree than any evergreen that will grow in this country. 

 We believe the finest specimen in' this country is in the Parsons 

 nursery at Flushing, L. I. It is now about forty feet across the 

 spread of its branches, which almost rest upon the ground. The 

 form is rather globular than pyramidal ; the height not being equal 

 to the breadth. Most other specimens are broad ovate-pyramidal. 

 Trees not more than twelve years planted in the New York Cen- 

 tral Park, are now upwards of twenty feet high, about the same 

 diameter of branches, and perfect in every way. It does well at 

 Rochester, N. Y., for six or eight years after planting, and then 

 gives indications of weakness and disease. 



An impression gains ground that this pine is not quite hardy in 

 the northern States. It is not possible to speak with certainty on 

 this point. It is hardy to resist cold, but it seems to be weak, and 

 to develop disease in the summer. The tree not being a native of 

 our country, may not adapt itself to our varied soils or climates so 

 readily as natives. But we still hope that, with care, when young, 

 it may be rooted in most parts of this country, so as to grow 

 healthily. 



The following remarks by H. W. Sargent in his Appendix to Down- 

 ing's Landscape Gardening, are interesting : " It is universally re- 

 turned to us as hardy from all parts of the country, though some- 

 times suffering from sun in summer. Near Boston this is the case, 

 and at Natchez, where plants have to be shaded from the summer 

 sun. Mr. Barry writes from Rochester it is hardy there, but will 

 not make an old tree. Our own trees at Wodenethe, sixteen and 

 eighteen feet high, certainly suffer from sun, and not cold. The 

 winter of 1855 and 1856, which destroyed some and damaged many 

 other white pines here, and even road-side cedars, produced no 

 effect upon this tree, which was entirely unprotected and uninjured ; 

 and yet, often in midsummer, it will become ruptured in its leading 

 shoots, and die back. This may be on the principle of the frozen 

 sap-blight in fruit-trees, where the damage done in winter does not 

 develop the injury before the succeeding summer ; but we are more 

 inclined to believe that the tree, if planted in rich holes, overgrows, 

 and a sort of apoplexy supervenes. We form this theory from ob- 

 serving' that, where a great growth has taken place, and the leading
