They both tend to grow together, if you begin from a period of depression. In such periods credit is bad, and industry unemployed; very generally provisions are high in price, and their dearness was one of the causes which made the times bad. Whether there was or was not too much loanable capital when that period begins, there soon comes to be too much.
