EXPERIMENTS WITH TOBACCO. 
VARIETIES AND ANALYSES. 
The following varieties were cultivated in 1888 and 
1889: 
1—Landreth. 2—Veulte Abajo. 3—Spandona (im¬ 
ported from Italy). 4—Wilson’s Prolific. 5—Dele de Suma¬ 
tra (imported seed). 6—Havana Seedling. 7—Spagnola. 
8—Cienfuegos. 9—Fiji Orinoco. 10—Spanish Hybrid. 
11—Persian Rose Muscatella. 12—Isabella. 13—Benta 
(imported, Italy). 14—Dele de Sumatra (Missouri seed). 
15—Golden Pryor. 16—Havana (rich soil). 17—Havana 
(poor soil). 18—White Burley. 
The analyses were made from the stripped leaves; 
the dry and ground tobacco was burned at a low red heat 
in a platinum dish to obtain the crude ash. The amount 
of pure ash is obtained by subtracting the water, carbonic 
acid, silica and carbon from the crude ash. The silica 
present might be called an accidental impurity, as most 
of it consists of fine sand which has blown upon and 
adhered to the plant. There is nothing in the method of 
analysis worthy of especial mention, except that the 
method of soda lime for nitrogen determination gives 
results below that of Kjeldahls’ method. The nicotine in 
No. 5 was determined after the method of Schloesing, 
and 2.85 per cent, was found present. Following is the table 
of results found in analysis of the eighteen varieties of 
tobacco grown upon the College farm, at the State* 
Experiment Station:
