252 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 



Any information along these lines which you may be able to supply for the 

 edification of the committee will be greatly appreciated. 

 Very respectfully, yours, 



J. Louis WILLIGE, Chairman. 



P. S. Kindly indicate additionally how much ice per day or per trip is 

 required to refrigerate a car for the transportation of milk at a maximum 

 temperature of 50 F. 



NOTE. Letters similar to the above were sent to the presidents of the Balti- 

 more & Ohio Railroad Co., the Chesapeake & Ohio Railway Co., the Southern 

 Railway Co., the Atlantic Coast Line, and the Seaboard Air Line.

DEAR SIRS: I beg to acknowledge the receipt of a letter from the chairman 

 of a special committee of the Washington Chamber of Commerce, requesting 

 certain information in connection with the transportation of milk in refriger- 

 ator cars over our lines to the Washington market from points in that vicinity, 

 and I have referred it to the third vice president, in charge of traffic, with the 

 request that prompt reply be made thereto. 



Yours, truly, JAMES MCCREA, President.

Philadelphia, November 21, 1910. 

 CHAIRMAN WASHINGTON CHAMBER OF COMMERCE, 



1202 F Street NW., Washington, D. C. 



DEAR SIR: Your favor of the 5th instant, addressed to the president of the 

 Pennsylvania Railroad Co., having reference to the feasibility of supplying 

 refrigerator cars for the transportation of milk over our lines from producers 

 shipping to the Washington market, together with a statement of the cost of 

 refrigeration of each car per day or per trip, etc., has been referred to this 

 department for reply. 



More prompt answer would have been given, but it has been found necessary 

 to refer these questions to the superintendent of passenger transportation and 

 the general superintendent of motive power, and the careful consideration 

 which those officials have found it necessary to make in connection therewith 

 has delayed replies. 



It is very difficult to answer a general question of this kind; that is, as to 

 the cost of refrigeration per car per day or per trip, and how much ice per day 

 or per trip is required for a refrigerator car for the transportation of milk at 

 a maximum temperature of 50 F., as there are so many conditions surrounding 

 a general proposition of that kind that would have a material bearing on this 

 question. 



There are three factors that would enter into the hauling of milk under re- 

 frigeration, namely, length of the haul, temperature of the milk when placed in 

 the car, and whether the cars would be loaded all at one point or at intervals 

 between originating point and destination. 



If a class "Rf " refrigerator car was used for this purpose, the initial icing 

 would require 7,400 pounds. After precooling, 4,000 pounds would be suffi- 

 cient to carry the milk under a temperature of 50 F. for a distance of 300 

 miles, or a 24-hour run. However, if the car were to be opened at different 

 points to receive milk, the temperature would fluctuate according to outside 

 conditions. 



The cost for icing a car with 12,000 pounds of ice would approximately be 

 $15; this on the basis of ice at $2.50 per ton, including the necessary labor. 

 By keeping the same cars in this milk service the bunkers would retain a per- 

 centage of ice from one trip until the next, and thus would require an average 

 of only about 3,000 pounds of ice, at a cost of $4, on the same basis as above. 

 The cost per gallon for refrigerated milk would depend on the number of 

 gallon cans that would be loaded in a car.
