or less, and whenever it does so, it ought to be changed. The 
operation of changing is easily done by one person, when the 
roots are only an inch or two long; but after the flower stems 
are of some length, and the roots nearly at the bottom of the 
glass, two persons become requisite ; one to take out the bulb 
and hold it, and to dip its roots once or twice in a vessel of 
clear water, to clean them a little; and another to empty and 
rinse out the glass, and re-fill it with water. It is essential that 
the water used for renewal or for rinsing the roots, should be of 
the same temperature as that which it is to replace ; and this 
can easily be done by pouring a little hot water into the cold 
water. Whether the water be hard or soft is unimportant.” 
Some persons add the size of a small pea of nitre to each fresh 
glass of water. We have thought it beneficial. 
77 Moles to destroy. It is sometimes with difficulty that these 
little animals are taken in traps, particularly where the propri- 
etor of a garden cannot, without committing trespass, pursue 
them in their misdoings. A Brussels work, on horticulture, 
translated in the Gardener’s Magazine, directs that powdered 
nux vomica be sprinkled on earth worms; that these remain to- 
gether two days, and afterwards be placed in the runs. The 
moles will eat them and be thereby poisoned. 
78 Scale on Pines. There are very few pine growers who have 
never had occassion to seek a remedy against the attack of this 
troublesome insect. Mr. John Rogers, who really appears to 
write from experience, has published a little work, “ The Fruit 
Cultivator.” In this, the venerable author, for he says that he is 
in his eighty-third year, observes, “Many remedies have been 
advertised for the desti’uction of the different insects which infest 
pines ; but the writer used but one, which he always found effica- 
cious. This was nothing more than sponging the plants with 
soft water, to a gallon of which was put half a pint of tobacco 
liquor ; and while yet moist, dusting the leaves with a hair-dres- 
ser’s puff, charged with the following ingredients, in pow der, viz. 
1 lb. Sulphur Vivum. 1 oz. Stone Vitriol, powdered. 
4 oz. Camphor finely powdered. 2 quarts of Soot, finely sifted. 
The whole to be well mixed, and kept dry in ajar, closely corked 
when not wanted for use. After this application, the plants 
should be kept in moist heat for a few days, at the end of which 
time all the insects will have fled.”
