7. " Don't put all your eggs in one basket," but try planting a small 

 quantity of well-known disease-resisting varieties ; for instance, the 

 " magnum bonum " is a heavy cropper, very disease-resisting, raid 

 though rather soft in the early season as compared with the 

 " champion," it keeps well right through the summer. 8. Don't 

 use the very smallest tubers for seed, because they are often not 

 fully grown, and therefore will not produce good results. You 

 would not use the lightest and smallest oats for seed ; why do so 

 with potatoes ? 9. Change seed frequently, and always select seed 

 from a perfectly different class of land to that for which it is 

 required ; merely getting seed from a distance is of slight importance 

 compared with getting sound seed from a different | class of : land. 



10. Keep the crop very clean, use the hoe frequently, because by 

 doing so you keep the plant healthy and avoid its being choked 

 with weeds, which help the disease to spread, ir. Always try to 

 plant on fresh ground on which potatoes have not been grown for 

 several years, because the spawn which reproduces disease can live 

 for several years in the ground, and could affect the sets as stated 

 in No. 3. 12. Earth up repeatedly with line, dry earth after each 

 hoeing, because the coating of earth prevents a great deal of the 

 fungus from reaching the potato when it falls from the leaves ; the 

 coating of earth also protects the potato from injury by slugs, 

 vermin, birds, etc.; and recollect that the disease enters the potato
