rent discrepancies in tlie various returns which we 

 have received from these places, and we are led, there- 

 fore, to these conclusions, viz : that the hardihood and 

 success of trees depend not exclusively upon climate, 

 and that a few degrees of latitude, north or south, are 

 of far less importance than proper soil and situation, and 

 that a thorough knowledge of what to do, which ex- 

 perience alone, after many mishaps, can teach, will 

 often enable us to grow trees at the North and East 

 which do not seem to succeed now at the "West and the 

 South. For instance, in the neighborhood of Natchez, 

 within six miles of that city, and on an elevation of three 

 hundred and twenty-six feet above the river, the 

 Gardenia Florida, the Pittosporum, the Magnolia fuscata, 

 the M. grandiflora, the Olea fragrans, the Myrtles in 

 variety, the English laurel, the Laurestinus, thrive 

 perfectly. 



The Deodar cedar and Cryptomeria Japonica, never 

 suffer except occasionally from caterpillars, and become 

 luxuriant trees ; there being specimens of the former 

 thirty feet high, and of the latter fifteen feet, with 

 branches in both trees sweeping the ground. Cunning- 

 hamia Sinensis is also perfectly hardy, and has reached 

 a height of from fifteen to eighteen feet, and yet the 

 Abies Smithiana is reported as not quite hardy and 

 sometimes injured by spring frosts, though at New- 

 port, the Abies Smithiana is said to be the hardiest of 

 all the spruces — more so even than the Abies excelsa 

 (the common Norway). Again, in a report from Penn- 

 sylvania, in the neighborhood of "Warrior's Mark, on 

 the side of one of the Alleghany mountains, at an altitude 

 above the sea of 1,020 feet, and in latitude 40° 40', and 

 where the thermometer has indicated 23° below zero, 

 where even the Ailanthus, Catalpa, and Paulownia are 

 annually cut to the ground, the Gryptomeria flourishes, 

 though browned, and the Deodar cedar survives, though 

 making little or no progress, when the cedar of Le-
