most easily where the skin is broken. 13. Recollect that the potato 

 requires potash. On most arable land 3 cwt. to 5 cwt. of kainit per 

 aere is of great benefit. 14. To produce its full effect on the crop, 

 kainit should be spread some weeks before planting. 15. Those 

 \vlio only grow small quantities of potatoes for eating would do 

 well to try cropping every alternate row with carrots, parsnips, or 

 some such crop, so as to let the potato drills be as airy as possible. 

 1 6. It is better to use a moderate dressing of farmyard manure, 

 with a small dressing of artificial manure, rather than a heavy 

 dressing of farmyard manure alone, because the warmth produced 

 by a heavy dressing of farmyard manure encourages slugs, worms, 

 etc., which injure the tubers, whilst the artificial manure helps to 

 keep them away. 17. If disease shows itself, earth up well at once, 

 so as to leave, say, 4in. of fine dry earth over the tubers, because 

 the earth-coating protects the tubers from spawn falling from the 

 leaves.
