form this judiciously, give a little about eight or nine 

 o'clock, more at ten, and the whole from eleven till twelve 

 o'clock, shutting again by degrees. 



Fire heat will now be dispensed with, but in frosty- 

 nights have the shutters on about sundown. The sun is 

 now powerful, and the house can be early shut up in the 

 afternoon, and will gain as much natural heat as will keep 

 up the required temperature, viz., 36 to 45. Perhaps 

 there may be uncommonly cold weather: at such times be 

 attentive to ward off danger by applying artificial heat. 



OF WATERING. 



Look over the pots and tubs at least every alternate day-, 

 to see where water is wanted. In watering, too much 

 caution cannot be used, especially during winter and the 

 commencement of spring. It was observed last month 

 what would be the effect of too much water. It may be 

 remarked, that if the exterior of the pot is very damp, the 

 soil inside is too wet, and, in that state, 1 is uncongenial to 

 vegetation, which now begins to start, and ought, by all 

 possible means, to be encouraged. People may be fre- 

 quently observed watering all plants indiscriminately, not 

 taking the trouble to look into or feel the state of the soil 

 in the pots or tubs, and thus, by going over them three or 

 four times in this manner, will be sufficient to put the 

 plants in such a state, that they will not be recruited for 

 some months. Hence the reason of so many sickly plants. 



Camellias, where there are collections, will continue to 

 flower. Treat them according to the directions given last 

 month. 



OF ORANGES, LEMONS, &c. 



Be sure they are not too wet, as too much humidity as 

 well as aridity causes their foliage to have a yellow appear- 

 ance, with this difference, that in the former case the foliage 

 is the same to the touch as when green ; but in the latter, 

 it is soft and dry. We have observed trees in tubs and 

 half barrels, with holes all round their sides. This is a
