MISCELLANEOUS FORESTRY PROJECTS 



Seed Treatment and Coating 



Research on coating tree seeds was started In 19^6. The object of this 

 project Is to treat seed to Increase the germination and survlvalf cmd to devise 

 and test means of reforestation by direct seeding* 



A number of experiments have been conducted In the laboratory and In 

 the field* In 1952) tests Indicated an Improved coating for seeds using calcium 

 llgno sulphonate, a waste liquor from the pulp sulphide Industry* Field data 

 from direct seeding studies Indicated some optimum depths for seeding* Experi- 

 mentation with the **Wallclng-stlck** seeder disclosed that the seed of the pine 

 species could be seeded satisfactorily without being coated* 



During 1953 a coating consisting of calcium llgno sulphonate and flyash 

 was experimented with until a satisfactory pellet for white and black spruce 

 seed was evolved* Three sites were seeded in Algonquin Park with the "Walking- 

 stick** seeder using pelleted white spruce seed and unpelleted red and white pine 

 seed* Results of this seeding were recorded in 195^* Seed treatment and coating 

 project was concluded in 195^* 



Cargo Dropping 



In 1951 research was started on design and construction of suitable 

 cargo parachutes for dropping supplies and equipment from aircraft to forest 

 fire fighters* 



In 1952 a number of parachutes made from ^ oz* factory cotton were 

 field tested* Eleven-foot and 8-foot diameter size cargo parachutes wer« 

 extensively used in the field in 1953* A l6-foot diameter size 'chute was 

 designed and field tested for pump work in 195^* These larger parachutes wer« 

 'supplied to the field for operation during 195**'* 



Future work should consist largely of a service nature developing 

 items and techniques upon demand or request* Project **Cargo Dropping** as 

 originally designated is now considered completed*
