thus affected. The records do not show, however, from what sta- 

 tions these less-than-carload shipments were made, so that it is 

 impossible to determine the aggregate additional rail transportation 

 expense. 



Gins are located on the Holton Interurban Railway. All cotton 

 which is shipped from these gins to a compress must pay the local 

 charges on this railroad to El Centro, no part of which is refunded. 

 Beyond El Centro compression in transit is permitted, and the 

 charges on carload. shipments to compress points are refunded under 

 Southern Pacific tariffs, as has been described above. 



The excellent roads of the Imperial Valley, which are seldom dis- 

 turbed by rainfall, make it more economical in some cases to haul 

 cotton by autotrucks or wagons to compress points. In actual prac- 

 tice it would seem that a relatively small amount is hauled in this 

 way. If the experience of the Imperial Valley Long Staple Cotton 

 Growers' Association is representative of that of all the shippers in 

 the valley, the amount so transported is slightly in excess of 3 per 

 cent. In computing the total transportation expense, however, ac- 

 count must be taken of the cost of the haul by wagon and autotruck.
