Now if we look at Table No. 4, we see that this year's results confirm 
those of last year, viz., that fairly large seed produces heavier yields 
than small seed, but is not so profitable. 
We also notice that large seed always produces more stems and more 
chats than small seed ; the large sets yielded 24^ cwt. per acre on an 
average, whereas small sets yielded cwt. per acre : this seems to 
prove that the more stems a potato produces, the greater the yield of 
small potatos. It is also worth noting that in a dry season the strong- 
haulmed varieties withstood the drought best and produced the heaviest 
yields.
