were as good as the juices of the best Louisiana sugar cane. There 

 is evidence of that. Here is a blue line which represents the 

 average of nine analj'ses of three varieties of sugar cane grown 

 in Louisiana, selected by and sent by the President of the Sugar 

 Planting Association. They came in excellent condition. They 

 were treated b}' precisely the same methods — by the same men who 

 analyzed the sorghum, and as you see, the average of the nine 

 anal^yses show that they were not quite so good as was this sorghum 

 at that time. The same is true of another variety — White Sibe- 

 rian — on the 18th of July. It follows up very closel}', almost as 

 though it was a duplicate variet}'. You will observe that when it 

 has obtained this maximum content of sugar it practicall}' main- 

 tains it from the middle of August to the first of November. That 

 is a matter of extreme importance. After it has reached that con- 

 dition it maintains it almost indefinitel3'. In this case it was onl}' 

 cut off b}^ a hea-v^' frost and subsequent thaw. 



Here is still another varietj' called the Chinese sorghum. When 

 that was first examined on the 7th of August, it contained 7 per 

 cent, of cr^'stallizable sugar in the juice, and it contained 5^ per 

 cent, of uncr3stallizable sugar in the juice. There is not a person 

 on the earth, who from a thousand acres could produce a pound of 

 sugar, the crop being in that condition. Here a'Ou see this crystal- 

 lizable sugar rapidh* increased, ran up and was approximately as 

 good as the others, but with this difference, that while these reached 

 their maximum or reached that average the middle of August, these 

 did not get there till the fh'st quarter of October, the first week in 

 October. 



Now the same is true of still another variet3' called the Honduras 

 sorghum, which had but a little over one per cent, about the 20th 

 of August, of cr^'stallizable sugar, and contained about five and a 

 quarter per cent, of uncr3'stallizable sugar, — even worse than the 

 Chinese sorghum for making sugar. 



Mr. Charles J. Gilman — When you speak of the one per cent, 

 and five per cent. , perhaps it would be a little more intelligible to 

 the audience to indicate exactly the import of that. Do 3-ou mean 

 to take it as a per cent, of something else ? 



Professor Collier — Certainl3\ When I sa}' one per cent, of sugar 

 I mean that one hundred pounds of juice contains one pound of 

 sugar. Most of the other ninetj'-nine pounds was water, but not all 

 water, bear in mind. These per cents, all have reference to the
