38 AMERICAN EXPORT CORN ( MAIZE ) IN EUROPE. 



quantities of corn to sell. With a view toward overcomino; as far 

 as possible the undesirable effects of these conditions the following 

 recommendations are made. 



RECOMMENDATIONS. 



(1) That the moisture content of all grain exported be kept as low 

 as possible, in order that high temperatures, long voyages, and other 

 harmful conditions encountered may not cause it to become heated 

 and damaged in transit. 



(2) That corn containing more than 13 J per cent of moisture and 

 wheat containing more than 12 per cent of moisture, at the time of 

 loading, be not stow^ed in ships against or near unprotected boiler and 

 engine room bulkheads, unprotected propeller-shaft tunnel coverings, 

 or in the coal-bunker holds of ships." 



(3) That partially artificially dried corn which before drying con- 

 tained high percentages of moisture or which had been in a heating 

 condition before being partially dried be not shipped for export.'' 



(4) That corn that has been partially or wholly artificially dried 

 and that has been mixed with corn not dried that contains high 

 percentages of moisture be not shipped for export.'' 



(5) That all corn shipped for export be made as clean as possible 

 and that care be taken to distribute evenly through each hold broken 

 particles of corn, dirt, and foreign matter not removable from the 

 grain, which usually collect under the hatches of the ships during the 

 process of loading. 



(6) That grain for export be not loaded into ships when it is raining 

 and that care be exercised not to admit water in any manner into the 

 holds where grain is stowed. 



(7) That all shifting boards and all dunnage of every description 

 placed in holds where grain is stowed be dry. 



a The investigations of the Office of Grain Standardization into the subject of air- 

 dry grain have not been completed, but sufficient is known from observations made 

 during three years' work to enable it to be said that thoroughly air-dried corn contains 

 about 12 per cent of moistine and that corn considered commercially dry contains 

 about 14 per cent of moisture. 



Tests made with wheat considered commercially dry ranged from 9 per cent of 

 moisture in wheat from the Pacific coast to from 12 to 13 per cent of moisture in that 

 from the East and Middle West. Indications are that the air-dry basis of other grains 

 will be found slightly lower than that of corn. 



b Observations of such corn in storage and in transit have indicated that it was 

 strongly inclined to heat very quickly, especially in ocean transit. Such corn should 

 be thoroughly dried and thoroughly cooled after drying. 



c As in the case of the corn referred to in the above footnote, such corn also showed a 

 strong tendency to heat quickly in ocean transit. No attempt will be made to explain 

 these phenomena until these investigations have been completed.
