Factory and industrial management . ively used for coal-handling plants aswell as many other purposes such as handling broken stone, sand andcement for concrete, digging ditches, on dredging machines, use, however, for which they are not to be recommended, al-though used, is for handling concrete or any similar mixture whichwould have the tendency to set and adhere to the buckets or mechan-ism. The buckets are designed to run around horizontal as well asvertical curves. Many of us use as a mental basis of comparison thefact that we have seen day laborers shovel dirt in the country at acost of 25 cents per cubic yard, and we know that if Ihe material ishandled several times at this rate (as it very often is), the expenseamounts up to a very considerable sum. Nature has supplied thecheapest of all methods of handling material—gravity, which shouldbe made use of very much more than it is, in self-dumping wagons,cars, buckets, which should, where possible, be dumped into bins or HOISTING AND HANDLING MACHINERY. 55.

Perfectly ob-vious facts, but not utilised to anything like the extent that theyshould be; for we often see material handled at the cost of from 25cents to a dollar that a good crane would handle for 3 or 4 gravity method evidently appealed strongly to Col.
