Not illustrated. 1920 edition. Excerpt: ...been made. Future Work The committee suggests that some of the following' subjects be considered for next year's work: 1. Continue the study of mechanical devices for handling ties. 2. Study the internal temperatures of wood under treatment, especially where the wood is steamed. 3. Study the moisture content of wood before and after steaming for both seasoned and green wood. 4._ Study the absorption in volume per cent and other results of preliminary steaming of seasoned material versus that without steaming for zinc chloride treatment.

I cannot let this go by unless he makes it clear to me. He says with a locomotive crane they figure 360 ties per man hour, or 11,520 ties with four men in eight hours. MR. GRADY: I want to say to you, Mr. Waterman, that has been done. The test that I have in mind was made at Toledo, and no doubt there are men here who can tell you it was done. The crane was put on a schedule basis of one train per hour, and if the plant handled ten trains in ten hours, that is 100 per cent efficiency. The men were supposed to handle one train every hour. They were 6x8 ties, 1,000 ties in the train. On this standard basis of one train' per hour they eventually got up to 130 per cent efficiency; in other words, thirteen trains in ten hours, if that will answer your question. Very convenient arrangements were had. There were two parallel standard tracks, a train of empties put on one of the tracks and a crane on the track parallel to it. Then they loaded the ties from a third parallel tram track. All the crane had to do was to pick up a tram more
