pass through an ash sapling 14 feet. 2 inches long. The author believes 

 that the V'essels of the wood are not limited in length and interrupted 

 by septa at frequent intervals but that they are continuous tubes running 

 the whole length of each annual cone of wood and that important move- 

 ments of water vapour and air may take place in them. Reasoning from 

 this it would appear that frequent alterations of atmospheric pressure 

 would be more efficacious than high temperature in drying timber.

Arthur, J. C, Rapid method of removing smut from 



seed oats. (Purdue Agricl. Expt. Stat. Bull. 103. p. 257 



—264. 1905.) 



This gives an account of a method of treating seed oats very ra- 

 pidly and in large quantities with formalin to kill the smut spores. The 

 method consists of the application of a spray of formalin Solution of 4"/» 

 strength, or weaker, using about 25 gallons of Solution to 120 busheis of 

 seed. The wet grain should lie in bulk for at least two hours, and pre- 

 ferably longer^ before being sown. Several elevators in Indiana are 

 already fitted to perform this Operation at a very small cost.
