The stars become entangled in themeshes of these mops and are raised in large numbers. Mr. Herman has made many experiments for the purpose of perfecting somebetter plan of combating this scourge. He has found, he believes, a prac-ticable method for use in localities where there is not too great a depth ofwater. His plan is to make a continuous wall or ridge of lime along theboundary of the bed to be protected. He has accomplished this by fillingpaper bags with quick lime and dropping these bags along the line. Thepaper serves to hold the lime from being carried away by tides while.

The water will of course slack the lime, butMr. Pausch states that so long as the lime barrier remains intact no starfishwill cross it. He has experimented quite extensively in this direction, and[ the opinion that the results attained will warrant the use of his methodsupon a large scale. One of his tests consists of placing starfish withinlime enclosures, and though kept there for considerable periods of time notone will attempt to cross the line which separates it from freedom. Mr. Pausch says that the lime barrier constitutes a veritable dead linefor the sea star. He considers the use of paper bags a somewhat clumsyplan for getting the lime to the bottom, and is now engaged in perfectingan apparatus by means of which he may feed the lime through a hoseor pipe so drawn over the ground as to leave an unbroken ridge of thematerial on the bottom.
