VARIETAL DESCRIPTIONS. 



The accompanying varietal descriptions, except where otherwise 

 indicated, have all been obtained from the sources of information 

 mentioned in the references. This information is not always stated 

 in exactly the same order m which it occurs in the book, magazine, or 

 seed catalogue from which it is taken, changes being necessary in 

 order to foUow a logical sequence in the presentation of available 

 facts. The Ust here presented includes only about one-fifth of the 

 varieties upon which data have been collated. In determining which 

 varieties should be included in this list, the writer has tried to keep in 

 mind the present or the past commercial importance of the variety, 

 its value from the standpoint of the plant breeder, and its general 

 interest to the older potato enthusiasts. Doubtless in the process of 

 selection some varieties have been included wliich could have been 

 dispensed A\dth, while others have been left out which should have 

 been included. Where comments have been made by the writer, 

 and particularly where there has been a suggestion of criticism as to 

 the renaming of an old variety or its resemblance to an existing one, 

 it has been done with the intention of dii-ecting the reader's attention 

 to these points. The main object in publishing these data is to make 

 available such information as it has been possible to collect duiing the 

 past ten y(!ai-s. It is important that the plant breeder sliould know 

 the parentage of the varieties with which he is working, in order that 

 he may have some idea as to what can })(5 expe(;t(!d from th(^ union of 

 any giv(!n panaits. It is equally dc^sii-abh? that iho })otato specialist 

 and the up-to-date grower should have at hand the original published
