No. 149.J 343 



torn up the pines, the path is discovered by the uniform size of the 

 new pines grown up since that tornado, and occasionally I found 

 oaks had taken the place of pines in the tornado paths. The 

 growth of pines in these paths is so extensively uniform, that 

 they may be compared to the teeth of a hatchel. In some of 

 these paths the trees are several hundreds of years old. 



Mr. Morris. — There is no difficulty in obtaining any number of 

 young pine trees. 



Mr. Bell had observed the young plants growing in some one 

 direction from the parent tree, indicating that the seeds had fall- 

 en thus to leeward in a blow. The young plants are quite vig- 

 orous, and are easily transplanted. 



, Martin E. Thompson. — They are quite sure in the transplant- 

 ing. It is best done in September, but will do at any time of the 

 year. I have observed yellow pine trees in New Jersey, all 

 young, not more than forty years old as big as my body, and I 

 am full sized. 



Tho;nas Bell, of Morrisania. — Many years ago I was cultivating 

 tobacco in Fairfax county, Virgina, and I found that in three 

 successive crops the soil was no longer worth anything ; and that 

 in most of the worn out tobacco lands left to their own fate, a 

 growth of pine trees covered the soil ; and that in some twenty 

 years, these pines were often cut down and burned on the soil. 

 ' After which tobacco was again planted for another series of three 

 years. And on such renewed pine soil I have raised the richest 

 Virginia tobacco. These crops were on light soil, much of which 

 exists in Maryland and in Virginia. 



Mr. Blakeslee, of Water town. Conn. — Two white pines were 

 cut down for their bright turpentine ; within twenty years after 

 they were so cut down a new growth of beautiful white pines 

 v'-made their appearance, and now they are nearly as thick as my 

 body ; these must have come from the seeds of the two parent 

 trees. On another field cleared up twenty-five years ago a growth 

 of red cedars succeeded ; these are now as large as my arm.
