REPORT OF THE 



No. 3 



Fertilizers. — Green manures were used extensively where possible, crops of 

 fall rye and buckwheat being ploughed under. Two plots were seeded to sweet 

 clover in the spring and a good catch has been obtained. In addition, the fol- 

 lowing fertilizers other than green manures, were applied during the year: — 



Demonstration Plantations. — No additions were made to nursery demon- 

 stration plantations this season, the only activity in this section being confined 

 to maintenance and the refilling of fail places. 



In the Manvers township municipal demonstration plot, 123^ acres were 

 planted to red, white, jack and Scotch pine and bands of poplar cuttings were 

 run across the wind direction. 



Property. — During the early part of the year a two hundred acre area, com- 

 prising lot 22, concession 1, Manvers township, Durham county, having been 

 taken over by the Department of Lands and Forests, came definitely under the 

 jurisdiction of this Forest Station. 



This land, which supported an uneven aged mixture of white pine, red 

 pine, red oak, hard maple and white birch, was logged for saw timber and ties 

 (oak) in the winters of 1923 and 1924. It was cut over for cordwood in the 

 winters of 1925 and 1926. Cutting, however, was restricted to a diameter limit 

 of eight inches D.B.H. for pines, and six inches D.B.H. for hardwoods and, as 

 a result, sufficient seed trees were left to ensure adequate reproduction. A 

 splendid young growth is already established consisting mainly of white pine 

 and red oak, with a fair percentage of red pine, hard maple and white birch 

 interspersed. It is hoped that some silvicultural operations may be commenced 

 next year. 



Irrigation. — The most important single operation undertaken during the 

 year was the laying out and installation of an irrigation system. As the success 

 of our nursery operations are so dependent on irrigation, all other activities were 

 made subordinate to this work. 



The water supply is obtained from a spring creek which passes through the 

 northeast corner of the property, along the east side and through the southeast 

 corner. A retaining wall thirty feet long by three feet above water level and 

 four feet below, was constructed along the creek and through an opening in this 

 the water is conducted by means of a foot-square concrete chute, ten feet long, 

 into a supply cistern 20 feet x 12 feet x 63/^ -feet. The water is screened in the 

 chute by a series of graduated mesh screens. ■ 



The pump house — a 15 foot x 18 foot cottage-roofed building — is located 

 fifteen feet beyond the cistern. In it are the engine and a three-stage centrifugal 

 pump. The suction pipe is four inches by twenty feet long, fitted with a foot 

 valve, while the discharge is three inches by 230 feet to the base of the tower, 

 which is forty-five feet above the water level in the cistern. From the base of 

 the tower the water is elevated 100 feet to the bottom of the 10,000 U.S. gallon 

 tank.
