miss-fires, which are often very dangerous, it is best, after inserting the cap in the 

 stick f powder to be used as the primer, to double the fuse round the end of 

 cartridge and tie it securely, putting in the priming cartridge-cap end first. This 

 prevents the fuse being pulled out during the process of tamping. (Sec Fig. 8.)

This picture shows the correct placing of the 

 charge where the stump has a tap-root. The root 

 will be broken off at sufficient depth to admit of 

 the use of a plough. 



The powder most generally used is 20-per-cent. nitro-glycerine, commonly 

 known as stumpiug-powder, which can be got at reduced rates through the various 

 Farmers' Institutes, which are linked up with the Provincial Department of 

 Agriculture. 



The tools required are a 2-inch auger about 4 feet long and a 4-inch auger 

 5 feet long, an ordinary long-handled shovel, and a long-handled spade which has 

 been bent round like a section of a pipe (Fig. 9), also a nipper for attaching the 



cap to the fuse. If stumpiug-powder is used, 

 in the spring particularly, it is often frozen. 

 Great care should be exercised in thawing it. 

 The sticks may be left in the sun, on the barn- 

 roof or some other sunny place, or, what is 

 better still, the box may be put in the horse- 

 manure pile overnight. The hole in the cartridge 

 in which the cap is inserted should be made with 

 a pointed stick, not with a pice*. 4 of metal. 

 If the settler is not used to handling powder, it is better for him to get a 

 neighbour who understands it to help him, as an accident never happens twice to- 

 the same person. If several blasts are being set off at about the same time, do not 

 leave the vicinity until they have been counted and be quite sure they have all 

 gone off before returning. If for any reason one has missed fire, leave it for a 

 while and give it every chance, and when you do go back the best way is to start 

 another hole and put in another charge, as to dig out an exploded charge is a very 

 dangerous operation. 



STUMPING WITH SMALL BLASTS. 



There Is another system of taking out the large old-growth stumps which. 

 although not so popular as the big-blast method, is really more economical if the 

 settler does not put a very high value on his own time, but it can only be followed 

 out if the stumping is undertaken before the big logs and other fairly large debris
