Or, that the areas connected with musical representations lie near those of speech. An Experimental Pacific Type Designed with All Modern improvements to Provide the Maximum Power Per Pound of Weight To accomplish the purpose of the design--the maximum capacity per pound of weight--the largest boiler capacity within the predetermined wheel loads was the essential feature.'. This end was obtained by eliminating every pound of weight in all the parts that was not necessary to strength or durability and by utilizing the weight thus saved to provide a larger boiler and by increasing the capacity of the boiler thus secured by the use of fuel saving devices to obtain the utmost economy in boiler and cylinder performance. The design and construction of the boiler is shown in one of the accompanying illustrations.
