This is a statement over the signature of an engineer as regards the physical condition of a railroad or other property. This is further explained under the next subject, but the wording of such a certificate should be in form so as to show beyond peradventure that exhaustive examination has been made and that all construction was proper; that power, for example, is sufficient for the present needs, and likely to be so for reasonable future requirements; that, if a water-power enters into the proposition, the supply of water is sufficient at all times, and, if not, that proper provision has been made for auxiliary power by the use of coal, for example; and so on. In fact, on an " engineer's report " depends so much that too great pains cannot be exercised in studying into such a report and ascertaining if all reasonable care and precautions have been taken. Let the engineer be one of good repute and standing, and let his report be sufficient to set forth in detail all necessary information.

It has become the custom for railway and other public service corporations to allow for an extension of the property by a further issue of bonds up to a certain rate of the actual cost for such an extension, all based upon "engineer's certificates." It is, therefore, of extreme importance that these certificates should properly show the expenditure of this money. It is not a bad idea that an affidavit, signed by the president and treasurer of the company, should go with such reports, showing them to be true.
