of the next trench fills up the trench just

 The trenches should run from east to west, 

 if possible, and the soil disposed in ridges 

 so as to present a short, steep slope to the 

 north, and a longer incline at a more 

 gentle gradient to the south. When the 

 young shoots make their appearance above 

 ground, the crest of each ridge affords 

 useful protection to them until they have 

 outtopped it. The soil is lightened by 

 being broken thoroughly and thrown up 

 with the spade, and in this condition 

 permits more readily the entrance of air 

 and moisture. 



Potentilla (nat. ord. Rosa'cea). 



A genus of plants some of which bear 

 a resemblance to the strawberry in flower 

 and manner of propagation by runners, 

 inasmuch that they are sometimes taken for 

 wild strawberries. It must be understood 

 that the resemblance is not general, but 

 is confined to some species included in the 

 genus, many being shrubby herbaceous 

 perennials ranging from i foot to 3 feet 

 in height. These are propagated by 

 division of the roots and by seed. The 

 flowers are chiefly white or yellow, but 

 some species bear red or purple flowers. 



description, as far as the ordinary descrip- 

 tion of flower pot is concerned. The 

 majority of those in use are unattractive 

 in form, if convenient, and are made of 

 common potter's clay, similar to that which 

 is used for making the better and softer 

 kinds of bricks. The best, perhaps, that can 

 be had are those made at Weston-super- 

 Mare, which are good and cheap. The shape 

 of the common pot and saucer are shown 

 in the accompanying illustration. Pots 

 should always be unglazed, to admit of the 

 escape and absorption of water when neces- 

 sary ; but the interior of the water saucers
