 Should it be so, this fact would be of importance relative to the appearance 

 of the disease in the root houses or storage cellars.

C. Remarks About the Construction of Storage 



Houses. 



The growing demand for celery during the late winter months 

 has recently brought about considerable improvement in the con- 

 struction of storage houses; and as has been suggested, this 

 matter is intimately associated with the disease question. The 

 original type of root house, which I have not seen in New York, 

 was essentially a rail coop. Upon the rails, slraw and earth, or 

 manure, were placed in sufficient quantity to k* ep out cold and 

 moisture. Trade demands soon necessitated the form seen in 

 Figs. 54. 55, 56, for the storage of celery. This form is well 

 known, and the construction of this is easily made out with the 

 aid of Fig. 56, which is an interior view. The-e houses are 

 usually provided with double doors at both ends, two or more
