write confidently on the subject. At the same time 

 I am pleased to acknowledge the great assistance I 

 have received from Prof. Marshall Ward, Dr. Munro, 

 Mr. E. C. Beaven, and others, who kindly placed 

 at my disposal a considerable amount of scientific 

 information they have obtained during their researches 

 in connection with diseases, and other interesting 

 features connected with the potato plant. I am also 

 indebted to them for several excellent illustrations 

 they have permitted me to iise. 



Although a subject of general interest, the literature 

 dealing with potato culture is very limited, and most 

 of it is hardly in accordance with modern practices. 

 It is only fair, however, to give credit to the large seed 

 firms for the useful information they have circulated on 

 the subject, as well as for the substantial aid they have 

 given growers by the introduction of new varieties of 

 potatoes which possess so many valuable features. 

 My thanks are due to them for the illustrations of 

 types of potatoes which they have kindly supplied ; 

 also to those implement makers who have placed their 

 illustrations at my disposal.
