on the farm soil at a cost of $2 per acre, with very satisfactory 

 result. Even in the heather this simple, rough method promises 

 to work. 



All these experiments were made on waste lands. On forest 

 soil, after clearing, the humus accumulations seem inimical to the 

 success of the lupine, but it is perfect after burning over the 

 clearing or removing surface cover otherwise. 



Finally an account is given of the remarkable influence of Black 

 Locust on the root and growth development of spruce. The in- 

 fluence is similar to the lupine, the spruce roots seeking and fol- 

 lowing the locust roots into the depth and forming whole nests 

 of fibrils alongside on their bark. 



An entirely different root development was observed in a 6-year 

 plantation in clover, i. c, of esparsette, luzerne, etc., in mixture, 

 after oats. The development of the 3-year-old transplants was 

 very good, a height of nearly 3 feet, a diameter of nearly 2 inches 

 at base and a crown diameter of 2^ feet. The root system, how- 

 ever, was short (15-30 inches) with stout roots (|-inch) going 

 down to 12 to 14 inches, the depth being rather unusual, removing 

 the root competition. 



The author then refers to the relation of root development to 

 disease and insect damage especially June beetle, to which old 

 farm (waste) lands are so often exposed and against which the 

 deep rooting is the best preventive. 



In conclusion the author expresses his opinion that the alder 

 combination is best and cheapest, with 2-year-old, once trans- 

 planted (6 to 8 inches in the row) stock, planted 6 feet by 4 feet; 

 after 2 or 3 years spruce is planted, leaving the alder as nurses.
