Notes for 1899. — This year the seed was sown April 25. On May 

 29, when the plants were showing their second and third leaves^ 

 counts were made to determine the percentage of smutty plants. 

 The treated plats were found to average 20 2-5 per ct. of smutty 

 plants and the untreated plats 72 4-5 per ct. At this time it 

 was evident, CA^en to a casual observer, that the treated plats 

 were in considerably better condition, seemingly about 25 per 

 ct. better than the untreated plats. The plants on the treated 

 plats were larger and more numerous. The crop was harvested 

 September 6. 



Notes for 1900. — Seed sown April 27. A strong wind seriously 

 interfered with the proper application of the sulphur and lime. 

 On May 19 the plants were much injured by a dashing rain. 

 Counts made Mary 28 showed the percentage of smut-infested 

 plants on the treated plate to be 38^, and on the untreated 

 plats 80. Counts made June 11 showed 31 per ct. of diseased 

 plants on the treated plats and 52 1 per ct. on the untreated 

 plats. The earlier counts invariably show a larger percentage of 

 smut and are the most reliable. By June 11 there was a marked 

 difference in appearance in favor of the treated plats. The crop 

 was harvested August IT.
