seems reasonable to suppose that, as the season advances, 

 the injurious ammonium chloride formed at first is eitlicr 

 washed out of the soil or destroyed by further chemical 

 changes. This question will be made a matter of further 

 study. 



The spraying with Bordeaux mixture, although necessarily 

 nine times repeated on account of the unusual numl)cr of 

 heavy rains, must be considered to have been profitable, as 

 the yield was very heavy, while in general the crop this year 

 was light where spraying was not practised. 



Giant Pascal Celery. — Two rows were grown in each 

 plot; the plants, large and well grown, were set 1 foot 

 apart in rows 5 feet apart on July 19. Banking began 

 Septem])er 29, and the crop was put into the cellar in good 

 condition on November 4. The growth on plots 0, 1 and 

 4 was fair ; on the other plots, excellent. There was con- 

 siderable rust on Plot 0, while there was little or none on 

 the other plots. The weights in pounds of the plants (in- 

 cluding roots and a little earth) w^ere as follows : Plot 0, 

 443 ; Plot 1, 328 ; Plot 2, 478 ; Plot 3, 478 ; Plot 4, 348 ; 

 Plots, 568; Plot 6, 488. ^ 



The calculated averages will not be given until the crop is 

 blanched, since the earth, of necessity left adhering to the 

 roots of the plants as put into the cellar, is an element of 

 uncertainty. It may be of interest to state that these aver- 

 ages indicate little if any increase which can be attril^uted 

 to the fertilizers. 



White Egg Turnips. — This crop followed spinach, let- 

 tuce and table beets, without further manuring. The land 

 was reploughed and fitted and the seed sown on July 28, in 

 rows 14 inches apart. Soon after sowing a heavy shower 

 caused some washing across the plots, which was particu- 

 larly injurious on Plot 0. The crop was harvested Novem- 

 ber 8 and 9, and was of excellent quality. The yields in 

 pounds are shown in the following table : —
