Bombay. — The following are some of the definite con- 

 clusions which have been arrived at in this Presidency : — 



At Surat it has been decided to make a reduction in the 

 number of varieties so as to simplify the work, and to dis- 

 continue the cultivation of tree cottons as not one has given 

 a useful result. 



At the Ganeshkhind Botanical Garden it has been 

 proved that Bourbon only lasts for 6 years which is far 

 short of the 20 years of life claimed for it. 



At Dhulia it has been found that the white-flowered 

 Varhadi excels in yield and ginning percentage. It has 

 produced 1,500 lbs. of seed cotton per acre, of a value of 

 over Rs. 200. Comparing price and outturn it easily out- 

 strips in value all other Khandesh or Berar cottons. 

 Karkeli, although of very high quality, does not yield suffi- 

 ciently well to be remunerative. 



At Dharwar, Cambodia cotton has not continued to be 

 immune from red leaf blight. Mr. Main has arrived at 

 the following conclusions regarding it : — 



(1) Cambodia cotton can be grown most profitably in 



the early part of July in spite of the liability of 

 early sown cottons to red leaf blight. 



(2) The early sown crop begins to flower about the 



middle of November, but these flowers drop off 

 and bolls do not set till December-January. 



Bhuri again did badly. It suffered from the red leaf 

 blight believed to be the disease known as the Mosaic in the 

 United States of America. It appears to be less suitable 

 than Cambodia for the conditions obtaining at Dharwar. 



At the Gadag Farm, Cambodia Cotton has been proved 

 to be the most suitable substitute for Dharwar American 

 cotton in the eastern part of the Dharwar District, as it 

 surpasses it in yield and ginning percentage. 



The trials with numerous American cottons show that 

 they all require considerable acclimatization. Mr. Main 

 also finds that the green fuzz of the seeds of certain Dhar- 

 war American plants is not a fixed character as a number 

 of white fuzz seeded plants are produced from green fuzzed
