6 in. with small twine, which has a neater appearance than, and does not shade 

 so much as, common pea-sticks. The situation I have found quite suitable is 

 at the back walls of the late vineries. The pots so filled and staked are placed 

 on the top of the back flues, elevated to the glass as near as the stakes will 

 permit ; where they are to remain till the crop is gathered, which will be from 

 the 1st to the 15th of May. It will readily be seen that the peas are certainly 

 kept from the frost and severe weather, and have always plenty of air when 

 the weather is fine. They are watered rather sparingly at fir&t, but plentifully 

 as they advance into bloom. The following is the result of two years' expe- 

 rience on the above method : — In 1839 and 40 I gathered a peck of peas on 

 the 1st day of May ; on the 11th of last May, above two pecks ; and a peck 

 on the 15th, 20th, and 25th days of the same month. The whole was ga- 

 thered from pots standing on the back flues of two vineries, each 40 ft. in 

 length. I have tried the early frame pea, the Warwick, and Thompson's early 

 dwarf; but I have found very little difference as to earliness or produce. I 

 have tried to force peas in pits and various ways, and have found that they 

 will not bear forcing till they are out of bloom, and the pod set; then they 

 will bear it, and be forwarded admirably. I have tried them in the autumn 

 on the same principle, but could not get them after the 20th of November. — ■

The figures are executed with the very greatest care, and evidently faithful 

 representations of nature ; and the letterpress is copious, scientific, and also 

 popular. Under every species the generic character, and what belongs to the 

 genus generally, are stated ; next the section of the genus to which the species 

 belongs is described; then the specific character; next the synonymes, and re-
