The germination of the plots wa.s e.xcellent througliout, a result duo to the 

 use of good seed combined with a sufficiency of soil moisture, obtained by 

 thorough preparation of the soil and consequent conservation of the previous 

 summer and autumn rains. Irish blight did not make its appearance in any 

 of the plots, owing, no doubt, to the prevailing high temperatures and lack of 

 humidity in the atmosphere. It is said that no spores of this fungus are 

 formed below 40 deg. Fah. and above 78 deg. Fah., and that they are most 

 active at 72 deg. Fah. ; it is possible, therefore, that only rarely will the spring 

 crop in the upper North Coast be affected provided the seed is clean. On 

 the other hand, the autumn crop is very likely to be attacked by the fungus • 

 as a matter of fact, it almost invariably is attacked, and very few farmers at 

 present take the risk except in very small areas.
