the Scots pine often forming impenetrable thickets of stufif 20 to 30 

 feet high, 6 inches in diameter at the butt. 



These grassy plains, however, are considerably different in their 

 characteristics than the grassy areas in this country. On Hanmer 

 Plains there is an annual precipitation of 48 inches and an average 

 of 132 rainy days per year, temperatures in the last 13 years have not 

 exceeded 98 degrees nor have they fallen below 8 and in most years 

 not below 20 degrees. It has been proposed by Mr. Morrison to plant 

 trees of European and North American conifers in various spots on 

 the Hanmer Plains without any particular preparation of the site or 

 protection from grazing or other injury. In a comparatively short 

 time these will seed up the areas far to the windward and will finally 

 convert the whole plains region into a valuable timber region covered 

 with trees growing at an exceedingly rapid rate. This system would 

 be extremely useful on account of its economy. It probably could be 

 duplicated in no part of the United States since our grass areas are 

 very much more dry.

In restoring the forests in the area devastated 



Tzvo Species by the war, species should be chosen which are 



Not To Be of rapid growth and capable of furnishing usable 



Forgotten products in a short period. On the other hand, 



in restoring portions of the forest in the midst 



of otherwise undamaged stands, the work should be conducted with a 



view to obtaining new stands as nearly as possible of the same type as 



those already existing. This means high forests of conifers in the 



\''osges mountains and coppice under standards in the greater part of 



the forests in the plains. In the Vosges, plantations of the "green" 



form of Douglas fir are indicated. In the plains, black locust and white 



alder (Alnus incana) should be given careful consideration because 



of their rapid growth, ability to reproduce by suckers, and immunity 



from insect damage. White alder, while less known than black locust 



and producing a less valuable wood, is more tolerant, thrives in dry, 



calcareous soils, and suckers very abundantly. These, however, are 



not the two species referred to in the title of the article. From an 



economic point of view, it is essential to replace as quickly as possible 



the high forest trees which have disappeared whether the coppice will 



recover naturally or must be rcpl.-iced nrtificially. White (Weymouth)
