STATISTICAL DESIGN AND ANALYSIS 



The work of the Statistics Section was centered around the following 

 projects:

 the data submitted was analysed* These partly confirmed previous recommendations | 

 partly gave rise to new ones* A detailed report on the whole problem is forth- 



^- coming* 



2) Cull and Grading *- The survival in the first experiment of a series of 

 three has been observed and is now partly analysed* Farther work on this 

 experiment is now under way* A second experiment has been set out and. survival 

 figures can be expected by this fall* 



3) Red Pine Pathogens *- An experiment with thlram pelleting of red pine 

 seeds showed significant decrease of mortality as the effect of treatment* 

 h) A detailed report on the effect of planting depths and methods on 

 survival of conifers was prepared and published as Research Report No* 26* 

 5y An experiment on rooting of poplar cuttings was analysed, showing a 

 significant difference between species* The position of the cuttings showed 

 significEOit differences* Cuttings near the butt end proved better rooters* 

 6) An analysis of the preference of black weevils for the roots and stems
