THE WORLD'S ADVANCE 



This method quickly concentrates a 

 gallon of grape juice to one quart of 

 syrup without impairing the flavor. To 

 be exact, the flavor is improved because 

 of the fact that part of the cream of tar- 

 tar which gives acidity to the grape juice 

 is left in the ice. Some juices are too 

 acid, and this treatment improves the 

 juice. This is notably true of the Con- 

 cord grape, and in the case of the Ives 

 grape the "rough" taste is removed. 



Aside from convenience in handling, 

 this rich syrup will save freight rates. 

 It will be popular as a syrup for ice- 

 cream sundaes and as a flavoring syrup 

 in cooking. Of course, it is heated to 

 the sterilizing point before bottling. 



BAKING BREAD BY ELECTRICITY 



An electric bake oven has been built 

 for an enterprising Minneapolis baker. 

 One of the ovens was designed for bak- 

 ing bread, biscuits and cake for demon- 

 strating flour, baking powder and yeast. 

 The current consumption is 2,400 watts 

 for the first 45 minutes, and thereafter 

 about 300-600 watts. The temperature 

 is 400 to 550 degrees F. 



The baking oven has two-inch heat 

 retaining walls with highly polished steel 

 covering. The framework is of angle 

 iron and the corners of bronze. The 

 metal fittings are nickel plated. 



CYCLOMETER MEASURES WORK 

 OF HARVESTER 



A resourceful ranch owner in Wash- 

 ington measures the number of miles 

 traveled by a 

 harvest ing 

 machine and 

 the number 

 of acres of 

 grain that it 

 cuts by using 

 a bicycle 

 wheel on 

 which a 

 cyclometer is 

 mounted. 

 The bicycle 

 w'h.e el is 

 turned by 

 making con- 

 tact with the 

 top of the 

 large wheel 

 of the harvester. When a sixteen and 

 one-half foot swath has been cut for a 

 distance of one-half mile, one acre has 

 been harvested.

WOODEN FLAGSTAFF OVER TWO 

 HUNDRED FEET HIGH 



"The longest flagstaff produced in 

 British Columbia will be forwarded soon 

 to Great Britain as a present from the 

 provincial government, and will 

 be placed in the Kew Botanical 

 Gardens, a few miles out from 

 London," says a report by R. E. 

 Mansfield, United States Consul- 

 General at Vancouver, B. C. 

 "The tree from which it was 

 made was a perfect specimen of 

 fir pine, and the staff, which is 

 216 feet in length, is without 

 flaw or defect. 



"In its original state the stick 

 was 5 f ee t m diameter at the 

 butt and 14 inches in diameter 

 at the top, and perfectly straight. 

 Dressed into shape, the staff has 

 a diameter of 32 inches square 

 at the butt for a distance of 16 

 feet. For the next 100 feet it is 

 octagonal in shape, and for the 

 last 100 feet it is round. The up- 

 per 200 feet has a gentle taper.
