“ We ought not to presume, from the general language used, that the railway company intended to cripple itself in the use of salable municipal securities in order to place upon the market its own bonds of less value. Our conclusion is that the mortgage was not intended to deprive the mortgagor of the privilege of using, in any way it desired, bonds or other securities to which it had an absolute or contingent right, and which it had obtained for the purpose of being used in building and equipping the road. ”
