Street-peas are a great ornament to flower-borders in autumn. 

 The seeds only require to be sown in drills or in clumps in April. 

 Gardeners who raise Sweet-peas for tlie London markets, sow 

 them in the autumn in pots, and secure them from severe weather 

 by placing them in hot-bed frames, by which means they can 

 bring them early to market. They may be continued in flower 

 the whole summer by repeated sowings in the spring. When 

 sown in pots they require to be frequently refreshed with water.
