6. Sewage Sludge. 
When sewage sludge can be obtained near at

being great for the potatoes to become “ scabby.” 
7. Ground Lime and Chalk. 
I have in previous reports alluded to the fact that “ground 
lime ” is a material of somewhat uncertain quality, and that 
care must be exercised in its purchase. The following are
