Mr. W. Wakefield gives these good 

 directions : — 



" To prevent dampness there must 

 be a free circulation of air ; the plants 

 must be placed on a dry bottom ; and if 

 they are in a situation which will admit 

 of a fire occasionally, it will render the 

 pits or house dry, but it should be used 

 very sparingly, and only when abso- 

 lutely necessary. But even with all i 

 care and attention, damp will attack | 

 some plants, and generally those that I 

 are most succulent in their nature, or 1 

 the young and tender tops of others. 

 We should therefore watch narrowly 

 and remove every leaf or shoot affected, 

 as damp not only destroys the indi- 

 vidual immediately affected, but ex- 

 tends its influence to those in the neigh- 

 bourhood of the one so affected. It is 

 contagious; it engenders mould, which 

 being a speciesof fungus, is rapidly dis- 

 seminated, attacking and destroying 

 wherever the damp has prepared the 

 leaves for its reception. Neither should 

 plants be too much crowded, as that 

 obstructs the free circulation of air. 



" Watering should of course be done 

 sparingly, but still it w-ill be required 

 occasionally. Care, however, should 

 be taken to preserve the foliage as dry 

 as possible, as, there being but little sun 

 in winter, and that not of sufficient 

 strength to evaporate the superabundant 

 moisture rapidly, it quickly rots the 

 leaves, especially of Pelargoniums, and 

 similar plants having leaves which form 

 a kind of dish in which the water ac- 

 cumulates in considerable quantities. 



" When fire is had recourse to for dry- 

 ing the house or pits, choose a fine day, 

 and give all the air possible, so that 

 the moisture dislodged by the heat may 

 be dispersed. 



" If the season is likely to be dry, 

 first make a hole for the plant, and in 

 the bottom of this put some rotten dung, 

 or any sort of material that will retain 

 ■water. Water this well, and then put 

 in the plant, filling the hole to within 

 two inches of the surface ; again water 

 -well, and then fill up the hole. 



" If obliged to water the plants after- 

 wards, cause the beds to be hoed over 

 next day as soon as they are dry enough ; 

 plants do better under this treatment 

 than by watering them so much as is 

 usually done when there is no appear- 

 ance of damp on the leaves over late in 

 the evening." — Gard. Chron.

HANDBARROW is best made of 

 this form : — 



Fis.77. 



The cage below is useful for carrying 

 leaves and other litter ; and when the 

 close moveable cover is on, it serves as 

 a conveyance for plants in large pots or 

 tubs, which, when in flower or bearing 

 fruit, might be too violently shaken in a 

 wheelbarrow. 



HAND-GLASS is a portable glass- 

 case used for sheltering cauliflowers 

 and other plants in winter, and during 

 early spring, or to retain a regular 

 supply of moisture to cuttings until 

 they are rooted. The most durable 

 and convenient are made with cast iron 

 framing of this form : —

They are sometimes made with movea- 

 ble tops as here represented, but the 

 only advantage it affords is, that several 

 of the lower portions may be placed
