PLATE 85 

 Relation of curing conditions to the development of smudge: 



A, B. — Comparison of onion sets artificially dried immediately after harvest with 

 those not dried. Photograph made at the end of the storage period after the two lots 

 had each been divided into three classes — namely, those free from disease, those 

 slightly diseased, and those badly diseased. (See experiment 1, p. 710-711.) 



C, D. — Comparison of white onion sets cured in shallow crates in the field under the 

 best of natural conditions with part of the same lot after exposure to moist conditions 

 for one week. (See experiment 2, p. 711-712.)
