Potatoes in 1906. — The season may be noted for largest yields ever 

 obtained before, and for superior quality as well. This was principally 

 due to a total absence of early blight and accounts for the fact that 

 the increased yield of the early varieties was proportionately greater 

 than that of the late varieties, for on the other hand, late blight came 

 earlier and was of more than average virulence, but as a fairly good 

 spray pump was secured in time, the blight was effectively checked by 

 spraying the vines with Bordeaux Mixture. The varieties used have 

 been tested several years except the Green Mountain, the seed of which 

 was kindly donated by the E. L. Cleveland Co., of Houlton (Maine). 

 The variety is of the Carman type and constitutes the main market 

 crop in the potato districts of Maine. Oblong and slightly flattened, 

 the potato has the square shaped form of the leading market varieties. 

 It's white and linely netted skin, shallow^ eyes, fine grained flesh and 

 good keeping qualities ought to command it as a desirable market crop. 

 It ripens about a week earlier than Carman. The plot was on a side 

 liill, from which most of the top soil was originally removed, and on 

 better ground the yield would have been no dou])t still larger. All 

 seed potatoes were treated with formalin for llie ])i'eveution of scab 

 and tlie treatment was eftective on all plots except the one ui)on which 

 the varieties in the following table were tested and where about 15% 

 of the potatoes were more or less scabby when harvested. Evidently 

 this was due to the fact that the same ground had been used for pota-
