THE MOUNT DESERT REGION 49 



The dredging' table is made of cypress, it is 3 feet wide 

 by 7 feet in length ; the height from the deck is 3^ feet, which 

 is the most convenient ; and the inside depth is 10 inches. The 

 bottom of the table slopes to the center, where there is a 

 sunken coupling to which a 2-inch hose connects, leading to 

 the connection in the floor of the cockpit. This slope in the 

 table is very slight so that jars and bottles may be placed on it 

 without upsetting. The bottom of the table, after two coats of 

 marine paint, is covered with canvas and then given two more 

 coats, and with one coat a year it is as good today as when 

 it was made. Along the inside bottom edge of this table is a 

 raised strip on which the frame holding the sieves is placed 

 and on which it may be shoved back and forward. See figure 

 15. Into this frame can be easily slipped any of the sieves and 

 these sieves are made so that each may be fitted into the 

 other. The sieves are stoutly constructed, which is necessary 

 if they are to be of service, and are shown in figure 15. I 

 found three sizes sufficient — yieth, ^eth, and %th mesh. In 

 addition, mud was taken from the dredge when it came up and 

 washed out in jars in the laboratory when searching for 

 smaller forms. 



One of the conveniences of this method is that the dredging 

 table can be lifted out of the boat on the return to the labora- 

 tory, as can the sieves and the davit. Also, when out in rough 

 weather or traveling from point to point, the dredging table 

 could be turned upside down and the davit and dredges 

 placed on it, adding greatly to the comfort of traveling in 

 rough weather. 



After a short trial, a small gasoline hoisting engine fastened 

 to the cockpit was discarded because its vibration racked the 

 cockpit so that it would leak and it made more of a mess than 

 it was worth. I therefore put an oak table, securely bolted 

 through to the frame of the cockpit and on it a set of gears 

 so that the dredge could be hauled by hand. This was found 

 satisfactory and a further description is unnecessary, as it is 

 shown in figure 14.
