20,6 ° Mendiola: Weight and Ash Content of Tobacco 645 
In this harvest only three plants were taken as samples from 
each chamber; namely, plants 5, 6, and 8 from the humid room 
and plants 4, 8, and 9 from the dry room. 
The average height of the harvested plants, number of leaves 
per plant, average length of roots, and average weight of roots, 
stems, and leaves per plant were determined, and the figures in 
Table 5 were obtained.

Tables 6 and 7 contain the figures obtained from moisture and 
ash determinations, respectively; the percentages of moisture — 
are based on fresh weights, while those of ash were figured on 
the dry-weight basis.
