The director of the survey reports that the work is well received by farmers, and he gives some excellent reasons why it should be. Boundary marks have so generally disappeared that in tracing the boundaries of eleven counties where sixty corners had been made, only two were found. It is a part of Mr. Gardner's plan to preserve these old lines, marking them in a permanent manner. The cost of bad work appears to have been very large to the people. The citizens of the State spend $40,000 for maps that are really worthless. Designing persons obtain aid for improper enterprises by exhibiting false maps, and there is no means of disproving their assertions. Counties and towns have contributed large sums to such projects, and the total is estimated at forty million dollars. Half of this was paid for the Oswego Midland railroad, which Mr. Gardner says would never have been built had its supporters known the character of the country it would cross and the ruinous original cost and running expenses involved in its heavy cuttings and high grades. The cost of surveying the whole State is estimated at $200,000 for the trigonometrical work, which is all that is now projected. To this must eventually be added topography and mapping, though these are not necessary for fixing boundaries. Still, the whole sum required, distributed as it would be over ten years' time, would be a light burden and a remunerative expenditure. * * * * * THE USE OF AIR IN ORE DRESSING.
