MASKED LUBRICANTS
"JUST
UST as good as Mobilot at half the price" is one of
many masks inferior lubricating oil hides behind.
A trial of Gargoyle Mobiloil has, time and time again, unmasked poor quality oil.
Many are the dollars spent on unnecessary repairs- all due to the use of good looking, inferior lubricating oil.
اکھ
And to hear a man. say: "I do not know the name, of the brand of oil I use" makes the average wage earner do some tall wondering. Probably using a masked oil and pay. ing through his nose for it.
Let Müblloi prove to you what. there is to efficient lubrication. Let it unmask the lubricant you now use. Let it prove to you that it is the most economical lubricant available-bar none.
All you have to do is to drain off the old oil while the engine is hot and refill to proper level with the correct grade of Gargoyle Mobileil.

PNEUMATIC TYRES.
"What date was the pneumatic tyred safety bicycle first used on Australian roads?" This interest- ing quary was recently addressed to the Dunlop Perdriau Co. A search through the company's recorde dis- closes the fact that Mr. Geo. R. Broadbent, one of the best-known Australian wheel-men in the cycling world, roda a Baylias- Thomas bicycle shod with Dunlop pneumatic tyres in 1891. The machine weighed 57lb., was geared to 58in, whilst the wrapped-on tyres were of 21⁄44in. diameter. The tyres had non-return valves. Broadbent used this machine in a 50 mile road race from Kyneton to Melbourne that year, and establish- ed fastest time. Two other well known Victorian cyclists, who, at the same period were using pneu- matics, ware E. Rudd and A. Daff. At the time all kinds of unfavour able verdicta were cast on the cum- bersome looking air-inflated tyre. It was not until about 1893-4 that the Dunlop detachable tyre, known as the Dunlop-Welch type was In- troduced into Australia. It is a re mirkable fact that the same prin ciple of prematie tyre attachment Is practically identical to-day throughout the world, not only on millions of bicycles, but on over 80,000,000 motor cars and trucks.
