256 ON FORMING THE DIRECTIONS OF PLEASURE-GROUND WALKS. 



to attach a pipe, which may be of lead or iron, and be carrie 

 round the house and enter the boiler near the bottom. If the party 

 choose the pipe may be carried along a channel in the floor, and some 

 fancy trellis iron-work be placed over it, which would be rather 

 ornamental. A single pipe of two-inch bore would be quite suf- 

 ficient to attach to the small-sized boiler. As the main point in the 

 management of a greenhouse in the winter season is to keep it in a 

 healthy state, but very little moist heat would be required; it would, 

 nevertheless, be well to have two or three tin troughs, about a yard 

 long, to place on the pipes, and fill them with water, which would 

 give a moist heat at any desired time. It cannot be too strongly 

 remarked that too much fire heat is very hurtful to most greenhouse 

 plants in the winter, enough only being required to keep out frost, or 

 to dry up damp, which should be done by lighting some fire in the 

 morning, and opening some of the sashes, if the weather will permit 

 it, and let the fire go out towards evening, except the weather be 

 severe, in which case enough fire should be kept in to raise the ther- 

 mometer to about forty degrees, which would be quite sufficient in 

 ordinary frost ; the water would not require to be heated above blood 

 heat to keep up the desired temperature.

ON FORMING THE DIRECTIONS OF PLEASURE-GROUND 

 WALKS, &c. 



B\' AN AMATEUR LANDSCAPE GARDENER. 



Much perplexity occurring in giving a proper direction to the walks 

 of a shrubbery or pleasure-ground, and having had a considerable 

 share in marking out the lines of walks in various situations, induces 

 me to transmit a few hints on the subject, hoping it may in a de- 

 gree assist some of the readers of the Floricultural Cabinet in 

 such operations. 



Walks are not formed by nature, but are the efforts of man or 

 beast, &c, and the difficulties existing in opposing objects render 

 curved lines and circuitous directions to be taken. The refined taste 

 of modern gardening, especially among trees, shrubs, &c, is to reject 

 straight paths, but unless there exist a reason beyond this, to adopt it
