88 . Report op the Botanist of the 



On the other three treated plats 750 pounds of sulphur and 

 375 pounds of lime were applied broadcast before the seed was 

 s-own; one plat receiving the application for one year, one plat 

 for two years, and th^ third plat for three years, as described 

 above. 



The field on which this series of experiments was made lay to 

 the east of Series I field, joining it at Plat L. The rows were run 

 lengthwise across both fields; hence in Series II the rows ran 

 crosswise the plats. 



Notes for 1898. —The seed was sown April 23. The July hail- 

 storm injured the phmts very much, probably reducing the yield 

 by 50 per ct.; and the accompanying heavy rain induced a bac- 

 terial rot which destroyed large quantities of the bulbs. The 

 crop was harvested August 10. 



Notes for 1899.— In the fall of 1898 the field was given a dress- 

 ing of stable manure at the rate of eight wagon loads per acre, 

 and then plowed. On April 24, 1899, 'the sulphur and lime were 

 applied broadcast on Plats D, F, J and L. Plats B and H, treated 

 in 1898, were omitted this year because they were to be treated 

 but one year. The field was then thoroughly harrowed, after 

 which it was smoothed by " planking." The seed was sown April 

 25 at the rate of 8 pounds per acre. 



On May 27, Plat D (treated two years with 750 pounds of sul- 

 phur and 375 pounds of lime per acre) showed 36 per ct. of 

 smutty plants against 38 per ct. on Plat C (untreated). On 

 Plats D and F the stand of plants was thin, indicating that the 

 sulphur and lime had been injurious to the seedlings. The crop 

 was harvested September 6. 



Notes for 1900.— Field plowed in the fall of 1899. The follow- 

 ing spring commercial fertilizer was applied to the whole field at 

 the rate of 500 pounds per acre. April 20, sulphur and lime were 

 applied broadcast on Plats F and L only, and the field harrowed. 

 On Plats D and F the sulphur applied to them in 1898 and 1899 

 was still plainly visible. The seed was sown April 27 and the 

 crop gathered August 17.
