Garden Road

The widening of Garden Road will ronder this thoroughfaro much safer for both vehicle

und pedestrian traffic, and will be one of the most necessary and welcome improvements of the year. We are glad to learn that the original proposal for a 3' 6") footpath has been turned down.in] favour of a wider path. The orig- inal intention was no doubt based on the desire to give as much room as possible to traffic, on account of the large number of vehicles which use this roud, but such a narrow. footway would have boon extremely dangerous. in that pedestrians would have frequently had to step on to the road in order to pare other people comfortably. It would be quite a good idea if notices were erected when the work is completo, re- questing pedestrians to "Please keep to the Footpath," otherwise there is to be the same pedestrian congestion on the road whenever a Poak tram discharges its passon- gers. The amount of traffic al- most warrente a rail dividing the path from the road..

GARGOYLE

Mobiloil

Make the chart your guide

The price we, ask for Gargoyle Mobiloil is not an arbitrary charge for something that costa nothing extra to create but, on the contrary, it is a charge to cover the added cost of making the lubricant good enough to deliver the type of service which will live up to the buyer's highest expectations.

Poor quality lubricating oil may be purchas- ed at the same price charged for Gargoyle Mobil- oil the use of the word CHEAP frequently implies CHEAP IN PRICE TO BUY. Inasmuch as we have often referred to CHEAP oil-meaning CHEAP IN TERMS OF QUALITY-we mean that sometimes oils heretofore sold at cheaper prices than we charge for the various grades of Gargoyle Moboiloil are not retailed at the same prices; thus making it difficult for motorists to discriminate.

Cheapness in quality penalizes not only one's satisfaction, but from an investment atandpoint of view, it is extremely expensive; for, as a rule, the requirement for replacement of worn out bearings and other expensive metal is much more frequent than is the case with a QUALITY product. The very purpose of QUALITY is to give the utmost service, delivered is a manner that makes it a pleasure to use QUALITY and enable this type of service to continue over the longest possible period.

That is why Gargoyle Mobiloil gives one sweet memories of the day of purchase; why it brings customers back for more; why it makes loyal friends and boosters; why it enables the Vacuum Oil Company to build up a reputation that is recognised and accepted by people as standing for the best to be had.
