POT 



POU 



POTS FOR PLANTS. The com- 

 mon unglazed earthen pots are su- 

 perior to those that are glazed, be- 

 cause they allow excess of tluid to 

 drain off by their pores. The size 

 should be proportional to the plants. 



POT-STONE. A tough soap-stone. 



POTTER'S CLAY. Plastic clay 

 either of a white or red colour. 



POTTLNG. The placing of young 

 plants in small pots for the following 

 purposes : 



" The first and greatest end at- 

 tained by potting is the power of mo- 

 ving plants about from place to place 

 without injury ; green-house plants 

 from the open air to the house, and 

 the reverse ; hardy species, difficult 

 to transplant, to their final stations 

 in the open ground without disturb- 

 ing their roots ; annuals raised in 

 heat to the open borders, and so on : 

 and when this power of moving 

 plants is wanted, pots afford the only 

 means of doing so. It also cramps 

 the roots, diminishes the tendency to 

 form leaves, and increases the dispo- 

 sition to flower. Another object is 

 to effect a secure and constant drain- 

 age from roots of water ; a third is, 

 to expose the roots to the most fa- 

 vourable amount of bottom heat, 

 which cannot be readily accomplish- 

 ed when plants of large size are made 

 to grow in the ground, even of a hot- 

 house ; and, finally, it is a conveni- 

 ent process for the nourishment of 

 delicate seedlings. Unless some one 

 of these ends is to be answered, and 

 cannot be effected in a more natural 

 manner, potting is better dispensed 

 rtith." — (LiTuUey.) 



POUDRETTE. Dried night soil 

 mixed with charcoal powder, with 

 gypsum, with lime, with peat, or 

 merely dried in the air. The manu- 

 facturers usually reserve the process : 

 that with gypsum and charcoal is 

 best. From twenty to thirty bushels 

 the acre are used with great effect in 

 the drill, or sown over growing crops 

 in spring. It forwards the plant con- 

 siderably, but seldom lasts for more 

 than one season. See Nisriil Soil. 



POULTICE. " An external appli- 

 cation employed for promoting the 

 suppuration of tumours, or abating 

 painful inflammation. The chief in- 

 tention of the poultice is to retain the 

 heat on the tumour for a sufficient 

 length of time ; consequently, corn 

 meal, linseed meal are the best fitted 

 for poultices. The fatty matter usu- 

 ally added is to give softness to the 

 poultice, which is otherwise apt to 

 harden as the moisture evaporates. 

 Few farmers are aware of the value 

 of these simple applications in abating 

 inflainmation, relieving pain, cleans- 

 ing wounds, and disposing them to 

 heal. The poultice may be rendered 

 more soothing by opium, or increased 

 activity may be given by the addition 

 of common turpentine or chloride of 

 lime, and in cases of foul ulcers pow- 

 dered charcoal may be added. As 

 an emollient poultice for grease and 

 cracked heels, and especially if ac- 

 companied by much unpleasant smell, 

 there is nothing preferable to a poul- 

 tice of mashed carrots with charcoal. 

 It is always best to enclose poultices 

 in bags."
