AMERICAN EXPORT CORN ( MAIZE ) IN EUROPE. 39 



(8) That heav}^ freight, and especially damp cotton or wet lumber, 

 be not stowod in the holds of the ships upon the top of grain for 

 export. 



(9) That grain for export be not loaded into ships at any consider- 

 able time before they are ready to leave port. 



(10) That all grain-carrying ships be provided with additional or 

 "false" bulkheads in such manner as to provide air spaces of from 12 

 to 18 inches next to and between the boiler and engine room })ulk- 

 heads and those of the cargo holds; that these false bulkheads and all 

 metal shaft tunnel coverings be reenforced with plank sheathing next 

 to the cargo and that the air spaces thus formed between the bulk- 

 heads, as well as the propeller-shaft tunnels, be connected with venti- 

 lators, as shown in figure 6. 



(11) That when exporting wheat which contains considerable quan- 

 tities of wild garlic the advisablity of artificially drying and cleaning 

 the wheat in order to remove the garlic be considered.'* 



(12) That the commercial grades of corn for export be recast and 

 the grading be done in such manner that the corn may be bought and 

 sold upon the basis of its dry -matter content, considered together 

 with its apparent quality, and that 12 per cent of moisture be con- 

 sidered as a commercial basis from which to figure corn values. 



THE RELATIVE WORTH OF GRAIN ON A DRY-MATTER BASIS. 



Table XVI is here inserted as a guide to a better understanding 

 of the relative values of commercial corn upon a dry-matter basis. 

 This table shows the comparative values of the dry-matter content 

 of grain containing from 12 to 25 per cent of moisture, inclusive, and 

 at prices ranging from 40 cents to SI per unit of measure, that is, per 

 bushel hundredweight, etc. The comparative values as shown in this 

 table, as well as the principle upon which they are based, will apply 

 equally well to all grains, although the air-dry basis of other grains 

 is likely to be found slightly lower in moisture than that of corn. 



HOW TO USE THE DRY-MATTER BASIS. 



Tlu'ough the use of this table the relative value of the dry-matter 

 content of grain containing various quantities of moisture may be 

 quickly ascertained. Thus, if grain containing 12 per cent of moisture 

 is worth 40 cents per bushel (or other unit of measure) then grain 

 containing 22 per cent of moisture is worth 35.45 cents, and grain 

 containing 25 per cent of moisture is worth 34.09 cents on the same 

 basis, because corn containing 12 per cent of moisture at 40 cents 



o Bulletin 100, pt. 3, Bureau of Plant Industry, TJ. S. Dept. of Agriculture, gives 

 details and results of experiments in artificially drying wheat in order to remove 

 garlic.
