A\is its point or borer; B its handle. The point or beareri A, istwelve inches in length, and one inch and a half at its, greatestdiameter.. It is formed <strong>of</strong> two half cylinders, an exterior_ a,and an interiol"_ b. They are so arranged that when put toge<strong>the</strong>ri as at c, <strong>the</strong> exterior roils upon <strong>the</strong> interior_ causing<strong>the</strong> whole to presetit <strong>the</strong> form <strong>of</strong> a conical or tapering cylinder.The handle is made <strong>of</strong> strong wood, and in detachedportions, four feet in length, which may be counected at pleasure,by means <strong>of</strong> an iron band, as at d. Pl_he•object in.having<strong>the</strong> handle in detached portions is for convenience <strong>of</strong> trans-• portatlo_), and for increasing its length as eireumgauces maydemand. The instrument being closed, as represented st /t.B, it is forced into <strong>the</strong> peat or marl to <strong>the</strong> depth at'which <strong>the</strong>examination is to be made; <strong>the</strong>n by turning <strong>the</strong> handle to <strong>the</strong>right_ <strong>the</strong> pressure on tim exterior cylinder 9forces it behind <strong>the</strong>interior_ and in this manner <strong>the</strong> instrument is opened. It is<strong>the</strong>n forced downward six or eight inehes_ or <strong>the</strong> length <strong>of</strong> <strong>the</strong>cylinder, when <strong>the</strong> hollow becomes filled. The handle being<strong>the</strong>n turned towards <strong>the</strong> left, <strong>the</strong> cylinder enc]ose_ a portion <strong>of</strong>peat or o<strong>the</strong>r matter taken.from <strong>the</strong> spot where <strong>the</strong> instrumentstopped. Its precise depth is indicatedby <strong>the</strong> number <strong>of</strong> fee_and inches represented on <strong>the</strong> handle. +USE OF SHELL MARL AS A MANURE.In Europe_ as well as, in some parts <strong>of</strong> this country, shellmarl has long been considered one <strong>of</strong> <strong>the</strong> most valuable <strong>of</strong> 'fertilizers.
