It thus appear-? that in the Experimental Garden, Salt cake, at 

 the rate of 2 cwt. 96 lbs. per acre, gives more than double the 

 amount of produce as compared with that obtained where no 

 manure was apphed. It falls back in the Kitchen garden set of 

 experiments ; but in this, Nitrate of Soda and Salt cake are only 

 the third from the top • and it may be further observed that 

 where the Nitrate of J>oda and Salt cake were there applied, 

 there was a large proportion of small potatoes, and it may there- 

 fore be inferred that these had been produced late in the season, 

 and that the effect of the substances had not till then been in full 

 operation. It is also necessary to observe, that although sets 

 may be selected as nearly equal as possible, yet some will always 

 push stronger in the first instance than others, and thus obtain 

 an advantage independent of other circumstances. 



The Flat -stemmed White Celery (Wrench), proves to be a very 

 distinct sort, of compact growth, not tall, but sending up a good 

 heart 3 and standing the winter better than other varieties of 

 White Celery. It is not the same as Seymour's Superb White, 

 as some have supposed it to be. 



The Beet-root received from Cabul proves to be the Common 

 Mangold Wiirzel. 



Salt applied at the rate of J lb. to every ^20 feet of rows of 

 Celery, has not produced any decided difference in growth j but 

 being rather late before the experiment was commenced the trial 

 requires to be repeated. In the mean time the knowledge that 

 the Celery plants are not injured by salt is something gained ; 20 

 feet of one row had a pound applied in the form of a strong so- 

 lution, and the plants did not suffer.
