VEGETABLES — DESCRIPTION AND CULTURE. 211 



Celery be 2 feet in length, the depth of the drain or 

 trench shonld be 2 feet also. The Celery is now placed in 

 the trench as near perpendicular as possible, so as to fill it 

 up entirely, its green tops being on a level with the top 

 of the trench. Figure 66 represents a section across a 

 trench filled with Celery in the manner just described. 

 ~No earth whatever is put to the roots other than what 

 may adhere to them after being dug up. It being closely 

 packed together, there is moisture enough always at the 

 bottom of the trench to keep this plant, at the cool season 

 of the year, from wilting. That which is put in trenches 

 about the 25th of October is usually ready to be taken 

 up for use about the 1st of December, that a couple of 

 weeks later, by 1st of January, and the last (which we try 

 always to defer to 15th or 20th November) may be used 

 during the winter and until the 1st of Aprih For the 

 first lot, no covering is required, but that for use during 

 the winter months must be gradually covered up, from the 

 middle of December, on until 1st of January, when it will 

 require at least a foot of covering of some light, dry 

 material — hay, straw, or leaves — the latter perhaps the 

 best. I have said the covering up should be gradual. 

 This is very important, for if the full weight of covering 

 is put on at once, it prevents the passing off of the heat 

 generated by the closely packed mass of Celery, and in 

 consequence it to some extent " heats," and decay takes 

 place. Covered up in this manner, it can be got out with 

 ease, during the coldest weather in winter, and with perfect 

 safety. These dates of operations, like all others named 

 throughout, are for this latitude ; the cultivator must use 

 his judgment carefully in this matter, to suit the section 

 in which he is located. 



To save Seed. — Leave some plants where grown ; in the 

 latter part of February, take them carefully, cut off the 

 outside leaves, and remove the side shoots, and plant 

 them out in moist soil, one foot apart. Select those which
