Limited, Montreal, Canada, and London, E. C., England IN COMMUNICATING WITH PATRONS KINDLY MENTION THIS MAGAZINE THE SELECTION OF THE LUBRICANT LUBRICATION In the selection of a lubricant, two things must be considered: First-Is the lubricant efficient? Does it give perfect satisfaction at all times, or only part of the time? Second-Is the lubricant economical? Does it do its work at the lowest possible cost, or is it wasteful? Albany Grease is efficient because it will lubricate the bearings of any kind of machinery and line shafting perfectly. It can be used in any kind or style of grease cup, and will not gum, cake or clog. Neither will it corrode or discolor. ALBANY GREASE is economical because it stays where you put it and docs not run or leak away. It will flow just enough to give perfect lubrication-no more. Save your time experimenting by starting in with Albany Grease in the first place, for the more you experiment, the better you will like Albany Grease and the sooner you will use it. We'll send a quantity without charge for trial, if you are interested.
