diseases which, like common potato scab, are transmitted by 

 germs on the surface of the seed tubers. Again, he practices 

 a rotation of crops so that potatoes never follow each other 

 successively, and before they are planted again the field is 

 devoted for some years to other crops. In this way the fungus 

 left in the soil by the last potato crop may in some cases be 

 destroyed or lessened. 



A list of diseases of potatoes in this country would include 

 at least the following: early blight, late blight, leaf blotch, sun 

 scald, tip burn, brown rot, black leg, potato stem blight or 

 rosette, potato wilt, potato scab, wort disease and internal 

 brown spot. These may not be all, but they are enough to 

 give one an idea that if potatoes are to be grown successfully, 

 the grower must be prepared to practice "eternal vigilance." 

 He must also take advantage of all the results obtained by the 

 specialists on potato diseases and potato growing, working in 

 the United States Department of Agriculture, as well as of the 

 splendid work in experimental potato growing done by the 

 neighboring experiment stations of Maine, Vermont and New 

 York. 



Again, referring to the potato crop in tliis State, we see that 

 it stands next to the highest in total value, being exceeded 

 only by the hay crop. What is there that offers greater 

 returns per acre as a cash crop? It is one that fits into other 

 lines, like dairy farming, with the best of results. Let the 

 acreage of potatoes in the State increase!
