What? A Poisoned Sea in the 

 Atlantic Ocean? 



FOR the eighth time since 1844 fish 

 have been killed along the west coast 

 of Florida in an area of poisoned water. 

 Not only the water, but the air has been 

 charged with a suffocating gas, odorless 

 but irritating to the air-passages. The 

 last mortality was reported in October 

 and November of 191G. The Bureau of 

 Fisheries sent experts to the spot but 

 they were obliged to admit, after a care- 

 ful investigation, that the cause of the 

 strange occurrence is a mystery. One 

 explanation advanced is that earth- 

 quake shocks, possibly due to West 

 Indian hurricanes, released poisonous 

 gases from the sea-bottom. 



Using the Exhaust Gas to Make the 

 Engine Start Easily in Cold Weather 



A SIMPLE device to make your 

 automobile engine start easily in 

 cold weather and to prevent it from 

 sputtering before it gets warmed up, is 

 shown in the accompanying illustration. 

 It consists of a length of one-quarter-inch 

 brass gas pipe screwed into the exhaust 

 manifold and then wound around the in- 

 take manifold between the carbureter 

 and the cylinders. The free end of the 

 pipe is then bent downward and backward 

 under the car, so that the small amount 

 of exhaust gas passing out of it will 

 not be disagreea- 

 ble to the driver or 

 to the passengers. 

 It takes about six 

 feet of pipe to 

 make the device. 

 The heat of the 

 gas in the pipe 

 warms the intake 

 manifold so that 

 the incoming fuel 

 is heated and more 

 completely vapor- 

 ized. This gives 

 additional power 

 because of the 

 greater heat and ef- 

 fects a considerable 

 saving in gasoline. 

 It also prevents 

 carbon deposits. 



The heat of the exhaust gas warms the 

 intake manifold, vaporizing the fuel 



An ice formation resembling a giant cauli- 

 flower. It remained solid for several weeks 



A Giant Cauliflower of Solid Ice. It 

 Was Twenty Feet Tall 



DURING some freezing weather in 

 Alberta, Canada, the device which 

 takes care of the 

 overflow from 

 the oil w el 1 , 

 shown above, was 

 out of order, and 

 the gas and water 

 squirted high in the 

 air, freezing as it 

 fell. In about a 

 week's time, a 

 beautiful ice for- 

 mation resembling 

 a giant cauliflower 

 ornamented the 

 side of the build- 

 ing, and reached 

 twenty feet in the 

 air. Its beauty 

 was augmented 

 when the sun 

 shone.
