DIFFICULTY IN FORECASTING TIME OF BURSTER'S ARRIVAL. 



These few remarks will show how many and how serious are the 

 difficulties to be contended with in predicting the moment at 

 which a burst will arrive at any given point for up to the present 

 moment it has been found impossible to decide how far the axis of 

 the A may deviate from its vertical position before reaching the 

 coast, or whether the rate of atmospheric motion may diminish, 

 maintain or increase.
