The weights may be kept from vibration by allowing them to hang in a pail of water. A small pail of oil is better yet, since its great viscosity more readily checks any motion. Hav- ing pulled the line C taut in the correct position, it is an easy matter to adjust each bearing by throwing the string with the nuts on the ends over the shaft at the bearing to be tested, and adjusting the set screws until the line C is exactly central

The weights may be kept from vibration by allowing them to hang in a pail of water. A small pail of oil is better yet, since its great viscosity more readily checks any motion. Hav- ing pulled the line C taut in the correct position, it is an easy matter to adjust each bearing by throwing the string with the nuts on the ends over the shaft at the bearing to be tested, and adjusting the set screws until the line C is exactly central between the two ends of the string. You will notice that variations in the size of shafting do not hinder this operation in the least, as is the case when a line is stretched at one side and attempts are made to measure in from it to the shaft; and, furthermore, the presence of the pulleys is no ob- jection whatever. Any shaft may be tested in this manner during the noon hour, except when the belts interfere with the line C. Where this is the case suffi- cient time must be allowed to remove such belts as are in the way. If the shafting was put up with sticks, as above ex- plained, it may also be tested for the horizontal plane in a very few moments. If these sticks are not in posi-.
