out in the salt-marsh, beyond the living timber. Such 

 marsh has, however, a cedar swamp bottom, which has 

 been overrun by the tide. In the view it will be noticed, 

 that while no living timber is to be seen, stumps are pro- 

 jecting above the surface of the marsh on all sides. In 

 this case, the method of working the timber is the same as 

 in the preceding. The drawing was made at high-water, 

 and the shingler is seen working at the timber below the 

 tide-level. Twenty thousand shingles were taken from a 

 small spot near this, the present year. A good idea may 

 be obtained from the drawing of the appearance of these 

 lands, which are now being changed from timbered swamps 

 to salt-marshes. The heaviest part of the business in 

 making the shingles is done in the neighborhood of Dennis- 

 ville. 



AGRICULTURAL PRODUCTS. 



The leading agricultural products of the county, and, to 

 some extent, its agricultural condition and capabilities, 

 may be seen from the following statistical table. The 

 materials from which it has been made were collected by 

 the assessors : Richard D. Edmunds, in Lower Township ; 

 Stephen Hand, in Middle; Albert Peterson, in Dennis; 

 and Champion Corson, in Upper. In prosecuting the sur- 

 vey, it was found that agriculture had advanced very 

 rapidly since the United States' Census of 1850, and that 

 the returns made at that time would give a very inade- 

 quate idea of the present annual produce. Hence the 

 preparation of the present table, which, it is gratifying to 

 say, shows an increase beyond what was expected.
