It appears that, throughout, the least economical crop has been that 

 grown with heavy dung, which has been not a great deal better than 

 that grown with light dung alone. Light dung and chemical fertilisers 

 have given a better crop, but, on surveying all the records up to the 

 present, it appears that in our earlier years the best results were those 

 from light dung, phosphates, and 4 cwt. of nitrate of scda per acre, and in 

 later years those from light dung, phosphates, and 6 cwt. of nitrate of 

 soda per acre. 



Chemical fertilisers alone, however, when nitrate is liberally used, 

 seem to answer well without dung ; and probably, for land in good con- 

 dition that has been dunged for a previous crop, any special application 

 of dung for this crop may be dispensed with. But in that case the 

 dressing of phosphates should be liberal, and should be accompanied by a 

 dressing of 4 cwt. of kainit per acre (spread before the land is prepared 

 for planting), and the nitrogenous dressing should be heavy, say 6 to 

 8 cwt. of nitrate of soda per acre — half applied just before planting out, 

 and the rest in one or more top dressings later in the summer. Possibly, 

 as the crop does not flower until spring, part of the nitrate might with 

 advantage be reserved till after the winter. But this plan we have never 

 tried. 



Autumn-cut Cabbages. 



These are the Main-crop Cabbage, planted in summer and cut in 

 the autumn. Next to Potatos they form the largest crop of the market 

 gardener. They are well known as what is called an exhausting crop, 

 being " hungry feeders," and both their weight and their quality are 

 readily influenced by manuring. What has been already said of the
