The cured leaf consisted of about 75 per cent of wrapi)ers and 25 per cent 

 " seconds." Of the wrai)pers 45 per cent were light, 30 per cent medium, and 

 27 per cent darlv. Sixty per cent of the leaves were over 16 in. long. In 

 capacity, life, and burning quality the 1905 crop was superior to the crop of 

 1904, and showed a general rating above all domestic Sumatra-type tobacco 

 except the better Georgia and Florida grades. The cured leaf was produced 

 at Cocalico at a cost of 45 cts. per pound. It is believed that the cost per 

 pound of producing the sweated and sorted leaf will not be over 05 to 70 cts. 

 The items of exjiense are given in a table.
