While possibly structures favorable to the accumulation 

 of oil and gas may be found in the northeastern part of 

 the state, the chances of locating such structures are small 

 and there is no convincing evidence that such structures, 

 if located, would carry considerable quantities of either 

 oil or gas. Thus the district as a whole offers very little 

 encouragement to prospecting for oil and gas, and the 

 chances for success in such prospecting are veiy small, 

 while the chances for failure are very large.
