Note. I was desirous of repeating all those analyses in which so much foreign matter, 
as coal and sand, existed. Experience subsequently enabled me to avoid this objectionable 
state of the ash; still, the results are correct for all the elements except silica. In regard 
to this, I have been satisfied that it varies from 1* 50 to 5 per centum ; and it is probable, 
in those varieties grown upon soils of Lewis county, that they reach the maximum per¬ 
centage. The grain has a thick cuticle, and is rather dark ; and it is in these kinds that 
the silica is in the largest proportions.
