FOR HORTICULTURAL IXVESTIOATTOX. 



On page 117 the subappropriation for horticultural investigations, 

 which includes also the technical studies of the physiological changes 

 of vegetables while in the proces.ses of marketing and storage, (•arrie^ 

 an estimate of fl.oOO. wliich relates specifically to investigation of 

 vegetable transportation work. The questions of primary imjiortance 

 may be said to be those involved in transportation of northern pota- 

 toes, the whole <|uestion of production of j)otatoes against harmful 

 temperatures in transit in winter harmful both through freezing, 

 through the effect of c(»ld in unhealed cars, and the determination of 

 the relation of the heated-car temperature to the carrving qual tv of 

 the product wliere heater-car service is not maintained. 



This is needed especially with reference to the northern Mjiine. 

 Minnesota, and Dakota potato-growing districts, and the potato 

 producers and shippers have 



Mr. Anderson (interposing). We would not worry much now. 

 anyhow, as to how they behave in refrigerator cars or other kinds of 

 cars if we could get the cars. We will take a chance on how they 

 beliave. 



Doctor Taylor. Yes; until it gets down to about 2o° or 30° beh)W 

 zero, then sometimes there come very heavy los.ses on account of 

 freezing in transit wiien with the transportati()n charges already lying 

 against the shipment, rnfortunately these destructive freezes do not 

 always occur in years when potatoes are cheap. 



Mr. Anderson. I nt>tice in this item on page 1 l.'i that there is a pro- 

 vision for the investigation of these physiological and relateil changes 

 of fruits and vegetables during the process of liarvesting an<l while in 

 commercial storage, and in the same general item appears this item on 

 page 1 1."). What is the difTerence ^
