CULTIVATION OF ROSES IX POTS. 177

 in rooms, that method cannot be well adopted, 

 for the odor would penfetrate into every part of 

 the dwelling. They should in that case be brushed

 to made a strong tea of tobacco, fill a pail with it, 

 and while in a tepid state invert the plant therein,

 Eoses in pots are wonderfully benefited by a 

 watering of manure water about once in two 

 weeks. This water is very easily prepared either 

 in town or country. The droppings from the 

 horse or cow stable put into a large tub or barrel, 

 with water kept over it for a week or two, occa-

 of sea-fowls that has accumulated for centuries, 

 is very valuable for making liquid manure. A
