about $20. Assuming the cost of administration to be covered 

 from thinnings, etc., the investment has paid 5 per cent., leaving 

 the soil in a condition four times as valuable.

Stolz reports on the success of plantations 



Planting carried on poor heath soil with bog iron ore 



on by planting on raised beds of 12 feet width, 



Raised throwing the soil from ditches, 4 to 5 feet 



Beds. wide and 2 feet deep, over the bed and 



heightening the ground thereby 7 inches. 



Although expensive, nearly $15 per acre, the astonishing success 



of the plantation seems to justify the expense. After 32 years, in 



comparison with other plantations, both in height and diameter, 



and in volume the plantation on raised beds is considerably 



favored. 



A number of experiences from other localities support this 

 method as effective on poor soils. 



The same method of ditching was applied to a 20-year old pine 

 and spruce stand on washed, poor, gravelly soil in exposed north- 

 west aspect. The spruces hardly 3 feet high, the pines almost 

 shrubs, maltreated by Tortrix, oak sprouts almost creepers. 

 Ditches were thrown up every 12 feet, the soil carefully distri- 

 buted not to bury the plants, then additional pine, spruce and larch 

 planted. This proved an unnecessary expense for in two years 

 an unexpected revival in the original growth took place, spruces 

 making 18 inch shoots, and oaks astonishing by the richness of 

 their foliage, while a small area left in original condition re- 

 mained poor. Pine and larch, however, were crowded out by the 

 spruce. 



Similarly a 30-year pine stand of "umbrella" trees was revived, 

 by cutting out all but the best stem, distributing the brush and 

 covering it with the soil from the ditches, if foot wide. After 

 the soil was settled, it was planted with 4-year old spruce. After 

 20 years the stand had become a 6 to 10 foot spruce thicket, with 

 10 to 12 inch leaders, from which the last pine was being cut out.
