Such duties afforded a some- what unique opportunity for the applica- tion of science to a new development of the highest practical importance. The large and profitable traffic between Boston and Albany made that railroad company one of the first to undertake a system of block signals, and therefore here more than on any other Amer- ican railroad was worked out the development of the system peculiar to this country, Blod- gett made good use of the circumstances. European railroads had organized... very thorough systems of signalmen to safeguard the movement of trains, and the business on many American lines had so grown that the need was keenly felt for a similar protection, but the English arrangement required so large a staff' of men that the expense was prohibi- tive in this country. About five years before Blodgett entered the employment of the railroad company, it had begun to install the Hall system of train signals, which sought to substitute for an elaborate and costly corps of signalmen automatic appliances and electric currents.
