spite of having been harvested early, the plants were fairing well. 



I have seen a cheaper and modified form of the above structure 

 provided with a single air chamber outside of the rafters and first 

 boarding, with tarred paper covering the final layer of boards. 

 The odor of tar in the house has caused comment ; but if the 

 house is well aired and sunned before celery 

 is admitted, there seems to be no need to 

 fear even local censure. 



I know of no experiments with the soils 

 of storage houses ; but since even the sur- 

 face soil has some inflnence on the amount 

 of water evaporated, it might be well to 

 give some attention to this point. 



The improved form of storage house 

 which has been described above may be 

 suggestive to market gardeners who have 

 other vegetable products to store 

 for the winter markets, for in the 

 storage of almost any vegetable 

 product the same three essential 

 features are to be 

 borne in mind, 

 viz.: (i) protec- 

 tion against freez- 

 ing ; (2) a tem- 

 perature so low 

 that the activities 

 of the plant may 

 not be incited

and that the growth of fungi may be discouraged; and (3) proper 

 protection against excessive moisture.
