Sow of the round-leaved variety at the 

 close of January in a warm situation, to 

 be repeated in larger, but still small 

 breadths, at the commencement and end 

 of February, and to be continued every 

 three weeks until the middle of April, 

 when it rnnst be performed once a week 

 until the close of May, and then once a 

 fortnight till the end of July. In August 

 sow at intervals of three weeks until the 

 early part of September. Sow thinly 

 in drills half an inch deep and a foot 

 apart. The sowing should be in showery 

 weather, otherwise an occasional water- 

 ing must be given ; for if there is a defi- 

 ciency of moisture during the first grades 

 of vegetation, not half of the seedlings 

 will come up. The triangular - leaved 

 plants must be thinned to four or five 

 inches apart, and the round-leaved to 

 eight. Thin by degrees, separating them 

 at first only an inch or two, as the plants 

 of the several thinnings are fit for use. 

 The thinning ought to commence when 

 tbey have attained four leaves about an 

 inch in breadth. Kegular gathering pro- 

 motes the health of the plants. The 

 outer leaves only should be gathered at 

 a time, the centre being left uninjured, 

 to produce successional crops. This 

 direction applies chiefly to the winter- 

 standing crops; those of the summer 

 may be cut off close to the root. 



To oltaiti Seed. A. sowing of each 

 variety may be made in February or 

 March, according to the openness of the 

 season ; or, of the round-leaved variety, 

 some plants of a regular crop may be 

 allowed to run up in April or May ; and 

 of the triangular-leaved, some plants of 

 the winter-standing crops may be trans 

 planted in March. Set them twelve 

 inches apart. Spinach is dioecious, and 

 many ignorant persons, perceiving some 

 of the plants to have no appearance of 

 bearing seed, advise these to be pulled 

 ap ; but they are the male-bearing plants 

 without which the others would be un- 

 fruitful. If, however, they are very nu- 

 merous, some of them may be removed 

 with benefit to those that remain, care 

 being taken that some are left in every 

 part of the bed. When the seed is set 

 the male plants may be entirely removed. 

 When the seed is ripe in July or August, 

 the plants ought to be pulled up, and laid 

 to dry thoroughly on a cloth, previously 

 to its being beaten out and stored.
