Such is a valuable little piece of experience gained by proxy. The morals are three and obvious. First, every tank or funnel should be fitted with an irremovable strainer. Secondly, if this be not so, superintend refilling yourself and see that a temporary strainer is used. Thirdly, if grit does get into the petrol through omission of these precautions, and blowing a pipe becomes necessary, wrap up the mouth of that pipe with care, or preferably get somebody else, and best of all an idle bystander, to do the blowing for you. For this service, if rendered by a boy, a shilling is a sufficient recompense, and you may depart at your leisure; but if it be done by a man, especially if he be large and rough, give him half a crown, and stand not on the order of your going.
