Fertilizers applied each j'ear from 

 1889 to 18!)8 or 1899. No fertil- 

 izers used from that time to 1905. 

 Clover h-own in 1900 in place of the 

 roots and i)ioughed under in May, 

 1901, 1 Iff ore tlie roots were sown. 

 In 1903 clover was again sown and 

 plough(^d iinder in May, 1904. In 

 190r)-(]-7-8 fertilizers again applied 

 as in 1899. Clover discontinued.

 1897 inclusive. In 1898 and 1899 

 1,000 lbs. of the Thomas' phosphate 

 were used in place of the mineral 

 phosphate. No fertilizers used from 

 1900 to 1905. In 1905-G-7-8 fertili- 

 zers again used as in 1899 12 1212
