Gasoline storage is not developing asrapidly as the peak of demand is rising, and unless this relationshipis reversed the supply wiU thin out to a stringency in an early summerahead, even granted an adequacy of crude to maintain a shortage of crude at the same time supervene this stringencywill break into a shortage, calling widespread attention to the situa-tion.
