'' It is probable that as regards (1) the nefed for a chano^e of seed 

 potatoes and (2) the merits of one district over another in producing 

 good seed climate is the chief determining factor. Bearing this in 

 mind, and having regard to the varying climatic conditions which 

 prevail in different parts of Ireland, it is not advisable to confine the 

 analysis of the results to the general average return of all the centres. 

 Therefore, the average returns for each province should be studied, and 

 it may be of assistance in interpreting the results if the order of merit

of the diiferent plots as regards average total yield be shown in the 

 following manner : — 



In Ulster. — -Ist, Home-grown seed; 2nd, Connaught; 3rd, Ulster; 

 4th, Scotland; 5th, Leinster; 6th, Munster. 



In Munster. — 1st, Home-grown seed; 2nd, Connaught; 3rd, Scot- 

 land; 4th, Ulster; 5th, Leinster; 6th, Munster. 



In Leinster. — 1st and 2nd (equal). Home-grown seed and Con- 

 naught; 3rd, Scotland; 4th and 5th (equal), Ulster and Mun- 

 ster; 6 th, Leinster. 



In Connaught. — 1st, Connaught; 2nd, Scotland; 3rd, Home-grown 

 seed; 4th, Ulster; 5th, Munster; 6th, Leinster. 



"The following conclusions may be drawn from the results: — (1) 

 where sufficient attention is devoted to the selection and treatment of 

 home-grown seed potatoes, the frequent introduction of new seed is 

 Unnecessary; (2) as good crops may be obtained from seed grown in 

 Ireland as from imported seed." 



There is but one method by which potatoes may be selected for seed 

 so that the standard of trueness to type and yielding capacity may be 

 maintained unimpaired, and that is, by selecting from the field crop
