Listen to the Nose Flute of the 

 Untutored Filipino 



187 



IT is not an uncommon spectacle 

 to see a colored man play 

 a harmonica with his nos- 

 trils. When it is done, how- 

 ever, it always awakens a 

 certain degree of wonder. 

 Among the Filipinos a 

 flute is never played in any 

 other way, and it would 

 create as much surprise in 

 that country to see a man 

 play a flute with his mouth. 

 Why they see fit to play 

 with the nostrils instead of 

 the mouth we do not know. 

 Moreover, they do this with 

 the greatest ease, and can 

 play the general run of 

 music except the very fast 

 rag time. Dare we perpe- 

 trate a pun and say that it 

 must be a nose-pipe? 



roads. The body of the wagon 

 rests upon a system of springs, 

 which absorb all sharp shocks 

 that might cause the explosion 

 of the nitroglycerin. The 

 load consists of enough nitro- 

 glycerin to "shoot" several 

 oil-wells and of the necessary 

 tubes, tools, etc. The tubes 

 are filled with nitroglycerin 

 and cautiously lowered into 

 the borehole of the well. 

 The uppermost tube has at 

 the top a firing head which 

 is exploded by a falling or 

 sliding weight, called the "go- 

 devil" and sets off the nitro- 

 glycerin charge. From four 

 to six quarts ordinarily con- 

 stitute a charge, but larger 

 charges are used.

RIDING over rough country roads in a 

 spring wagon loaded with nitro- 

 glycerin is an occupation that is not 

 likely to appeal to the average man, yet 

 there are those who make it their business 

 to carry explosives and who 

 become so accustomed to the 

 hazardous 



work, that 

 they scarcely 

 give a thought 

 to the risk of 

 traveling, so to 

 speak, with a 

 potential 

 earthquake.

THE safest and most 

 convenient way of 

 firing charges in blasting is by using 

 the electric spark, and blasting ma- 

 chines for generating the required 

 spark are in general use wherever blast- 

 ing operations are carried on. Farmers, 

 who often have occasion to do blasting 

 of stumps, rocks, etc., but not often 

 enough to justify the expense of purchas- 

 ing a blasting machine will be inter- 

 ested in the suggestion offered by 

 Mr.W. A. Saun- 

 ders , New 

 Hampshire, 

 who made shift 

 to fire a circuit 

 offive charges of 

 dynamite with a 

 spark obtained 

 from a dry-cell 

 battery of his 

 autom ob ile, 

 when no blast- 

 ing machine 

 was available 

 on a certain oc- 

 casion. This is 

 a handy wrin- 

 kle to be ac- 

 quainted with 

 on occasion.
