Lightning report, J. B. Reynolds {Ann. /!/>/. Ontario Agr. Col. and Expt. Farm, 

 80{190',\, [>[>. 23-25).— A record is given of damage done by lightning to trees of 

 various kinds, animals, and larm buildings during the4 years L901-1904. An analysis 

 «»f the figures shows strong presumptive evidence as to the efficiency of planting trees 

 ahoiit farm buildings as a means of protection from lightning. "The planting of 

 trees, such as spruce, elm, or maple, near enough to buildings to protect them, hut Dot 

 so near as to endanger them, is Btrongly recommended. The trees should be planted 

 at such distance that when lull grown their branches will not touch the buildings."
