COOLEY HYBRID VARIETY. 



65 



The Havana Seed variety has loii^, rather pointed leaves with 

 hw^o veins. Only the tips of these leaves are suited to cij^ar-wrapper 

 manufacture, the middle and basal portions laolvino; the necessary 

 (juality for good wrappers. This portion of the leaves is used for 

 hinders and in some cases for blending with cigar-filler tobacco. Inas- 

 much as the value of the tobacco dei^ends on its capacity for pro- 

 ducing cigar wrai)pers, it is highly desirable and important that as 

 nnich of the leaf be utilized for wrapper purposes as possible. liy 

 crossing this acclimated variety with the standard Sumatra variety 

 a hybrid was secured which produces short, broad, well-rounded 

 leaves with fine veins. In other 

 words, the hybvi<l combines the 

 hard}' and acclinuited charac- 

 ters of the Havana Seed with 

 .some of the important charac- 

 ters of the Sumatra variety. 

 From the variations in the 

 plants of this hybrid it has been 

 found possible to i)roduce about 

 the tvpe of plant that is best 

 suited to cigar-wrapper manu- 

 facture which can be grown 

 under the soil and climatic con- 

 ditions of the Connecticut Val- 

 ley. 



The general characters of the 

 Coolev Hvbrid distinfruishinjr 

 it from the mother Havana Seed 

 variety are increased number of 

 leaves; shorter, broader leaves 

 with very small, fine veins; re- 

 duced seed production, and 

 more even texture of leaf from 

 tip to base. The average num- 

 ber of leaves is IG; length, 27 

 inches; breadth, lU inches; shape, very round; number of slickers, 

 2; size of suckers, small; height of plant, 29 inches; circumference 

 of stem, 2f inches; length of internode, 2 inches; time of maturity, 

 ninety- five days. 



It is necessary that the seed of this hybrid be saved under bag 

 to avoid the possibility of cross-pollination. If the seed is crost 

 with other plants, particularly with plants belonging to other 

 varieties grown in a region, it is probable that there will be con- 

 siderable breaking up in type and consequent deterioration of the
