The quantity of Irish potatoes that can be picked up after plowing 
out with an ordinary plow and elevator digger is shown in Table XLI 
in terms of yield per acre. The amount that can be dug with a fork 
and picked up is also given in the same table. Where the yields are 
the same, it is seen that 40 per cent more can be picked up after an 
elevator digger than can be gathered after an ordinary plow. It 
appears also that twice as much human labor is required to dig and 
pick up a bushel of potatoes by hand as is required to pick up after 
an elevator digger.

Averages for the operation of hauling potatoes from the field and 
unloading into the cellar are given in Table XLII by bushels in the 
load in terms of bushels in a day. The larger loads are the most 
economical from the standpoint of work accomplished daily. 
Arrangement of this data by distance hauled showed no relation 
between the distance and amount of work done daily.
