foot apart or more, according to circumstances. Drop in a 

 teaspoonful of the liquid and cover up the hole at once. This 

 remedy may also be used to kill all other forms of grub. 



The white grub so common in pasture lands is sometimes 

 troublesome among Roses newly planted. If a plant suddenly 

 wilts, dig carefully around it and you may find the grub at 

 work, or curled up if at rest, or he may have traveled along 

 to the next plant. Kill him and you may save the plant. 



Numerous beetles or chafers attack Roses outdoors. They 

 are of various lengths and colors. Hand picking on cool, cloudy 

 days, or in the early morning, or evening is best. If the grubs 

 in the ground are so numerous as to be a menace to the roots, 

 the ground may be forked up lightly and chickens turned in 

 among the bushes; they will eat the grubs with avidity. Or, 

 pieces of sod may be placed grass side down under the earth 

 where grubs are numerous ; these sods will attract the grubs and 

 they may be collected and killed. The carbon bisulphide remedy 

 may also be used. This will kill any and all grubs in the soil 

 without hurting the plants. 



Perhaps the most destructive pest on Roses grown under 

 glass, and the hardest to fight, is the leaf roller. These are 

 the young of moths or butterflies, which lay their eggs on the 

 leaves. They hatch into caterpillars about three-fourths of an 

 inch long, which envelope themselves in the leaves, curling them 

 up and, where plentiful, which they are liable to become if neg- 

 lected, will ruin a house. They fall to the ground when full 

 grown, and enter the soil, where they form a cocoon and re- 

 main until early Spring, at which time they come forth and go 

 through the round of reproduction over again, so that once a 

 place is badly infested it is hard to get rid of them. 



The best remedies are, hand picking of the caterpillars, spray- 

 ing the foliage with poison, and catching the butterflies. For 

 spraying the foliage, pan's green, not more than a teaspoonful to 

 ten gallons of water, applied lightly every day for a week, has
