Cleaning Tobacco Seed. 



Three years ago this division began a new line of work, that of clean- 

 ing tobacco seed for farmers of the State. Most gratifying reports have 

 been received from persons for whom seed was cleaned. The following 

 shows the trend of opinion among the tobacco farmers in regard to this 

 new line of work : 



"The tobacco seed I had cleaned by the Department of Agriculture last year 

 I gave to one hundred and twenty-five farmers, and find them all pleased with 

 the seed. I want to say that I find a great difference in the results where 

 seeds are cleaned. 



"First. I get stronger plants on beds, and have no small, inferior plants. 



"Second. The tobacco lives better; not having to replant, grows evenly, 

 not having any late, inferior tobacco to contend with. 



"Third. It matures uniformly, making the housing of the crop easier. 



"Fourth. I get a better grade of tobacco, heavier and more uniform. 



"Fifth. Better plants, regular growth, uniform maturity, heavier crops, 

 and better prices I find to be the result of cleaned seed, with which I am 

 much pleased. I am sending you today my seed for this year to be cleaned." 



From a very small beginning this work has grown till during the past 

 year we recleaned and returned to the tobacco farmers enough seed to 

 plant many thousand acres of tobacco. The farmers are thus appreci- 

 ating the importance of clean seed for the tobacco crop as well as for 

 other crops. 



The planting of clean seed of high vitality is of such importance that 

 it is hoped the tobacco farmers of the State will take advantage of the 

 opportunity the department offers and have all of their seed cleaned. 

 This work can be done more efficiently by the department than by the 

 farmers, as the Seed Laboratory has special apparatus for doing this 

 work. Several times the quantity of seed desired for sowing should be 

 sent to insure a sufficient quantity of cleaned seed. The seed should be
