type which should be introduced into general cultivation; 

 the second is less hardy in its nature. It is attacked by 

 Jassids this year and its superiority to Upland is so trifling 

 that it is not worth the risk of beinej maintained. The soft 

 Peruvian is one of the finest cottons ever grown in India. 

 Its low outturn (in .spite of its higher price), however, 

 brings it on a par with Upland. This variety should not 

 be distributed indiscriminately, but should be brought to 

 the notice of farmers of good position who would under- 

 take to give it the necessary care and attention. I would 

 advise that jour selections of American cottons be kept 

 down in number. Many at present existing do not differ 

 sufficiently from one another to deserve being kept separate. 



' As regards the Deshi cottons, a survey should be 

 carried out in each tract so that the dominant forms in 

 each can be extracted and tested comparatively as pure 

 types. Those passing the test could be rapidly multiplied 

 on seed farms for distribution to cultivators. It is almost 

 unnecessary to point out that aid should be given in the 

 marketing of the produce until the trade is disposed to pay 

 fair prices spontaneously. 



" Mr. Milne's discovery that root-rot is caused by a 

 nematode worm is most interesting and I hope he will 

 publish his notes as soon as possible. He has now on his 

 Botanical area pure strains of all the varieties of cotton 

 found in the Punjab. These can be compared with your 

 survey types and time could be saved by making a start 

 from these for your seed farms." 



Since writing the above I have heard that the cottons 

 of the districts of Lyallpur, Hissar and Lahore have been 

 surveyed with the following results : — 



Lyallpur Tahsil. — Gossypium indicum, yellow flower- 

 ed, is the prominent form. 

 Toba Tek Singh. — Gossypium sanguineum, both 

 broad-lobed and narrow-lobed, chiefly near 

 Gojra, and Gossypium indicum, yellow flowered, 

 in almost as great quantity.
