keep the side track clear ofcars when loaded. If a high-pressure engine arrives atthis station with a good train, and is obliged to take six orseven wood cars, they are compelled to double these ninekilos, while the compound is simply thrown into highpressure and the sand ejectors put to work. Under theseconditions the hauling capacity of the engine is increasedabout 40 per cent., and we consider it more economical torun these nine kilos in high pressure than to double thehill. Again, nearer Mexico we have a piece of li percent, grade three kilos long, not compensated for curva-ture. As this is a short hill, conductors have orders to fillout their trains along the level country before reachingthe hill, and are expected to double the hill if necessary.This is another place where the compounds are throwninto high pressure, and time and locomotive mileage issaved. With these facts in view, I think the compoundsshould get credit for the full value of the figures shown intheir performance.

Not even the most exag-gerative optimist would assert that the sanitary arrange-ments of
