a distance, the pines being 8 to 10 inches in diameter, a few of the 

 larch have succeeded, but the spruce have remained suppressed from 

 the first and are but 2 or 3 feet tall beneath the pines. That they 

 have all lived shows the wonderful power of spruce to withstand 

 suppression. Beginning at the top, Oberforster Krutina, who is 

 in charge of the Heidelberg forests, started a few years ago grad- 

 ually to take out the pine, with the result that the spruce has 

 developed rapidly and has apparently lost nothing in vigor due to 

 its half century of suppression. 



The growing stock of the Heidelberg city forest has more than 

 doubled in the past 75 years, as has also the annual cut. It is a 

 startling surprise to read in detail, from the working plans, the 

 amount and variety of forest products that this city forest produces 

 annually, with the maximum production apparently not yet in sight. 



On the brow of the high plateau to the south of the city and 

 looking toward the Rhine river valley is a forest experimental tract 

 which contains even-aged stands of Douglas fir, Engelmann spruce 

 and other exotic species. The arboretum contains many interesting 

 groups of trees and shrubs, among them being Juniperus sa« 

 bina, Juniperus virginiana, Tsuga canadensis, 

 Cedrus atlantica, Sequoia washingtoniana (36 

 inches in diameter and 37 years old) , Nyssa sylvatica, 

 Ginkgo bilob-a, Abies polita, Abies pinsapo, 

 Pinus peuce, Pinus monticola, Pinus lamber- 

 tiana, Thuya plicata, Thuya occidentalis, 

 C h a m a e c y p a r i s lawsoniana, Cedrus deodar, 

 Hicoria alba, and many others.
