everything must be left almost 
entirely to chance. On the con- 
trary, when the movable col- 
lecting apparatus is used the 
territory can be planted not 
with thousands alone, but with 
millions of young, of various 
ages, whose management is 
easy, since they are all bound 
together, thanks to their com- 
mon support, which permits 
them to be placed at will in the 
most favorable conditions of 
bottom, depth, temperature, 
and light. Inspection is also 
easy, and can be undertaken at 
any moment. At the end of 
three or four years, when the 
oysters should have attained 
marketable size, they can be 
culled, on account of their large 
number, and the largest sold, 
leaving still a sufficient number 
to assure the continuous and 
definite repeopling of the bed. 
Fascine collector (Fig. 7).— 
The most simple movable col- 
lecting apparatus, and the least 
expensive, at least in the be- 
ginning, consists of bundles of 
small branches of chestnut, oak, 
or elm, fragments of grapevine, 
or, in fact, of any wood con- 
taining no poisonous or aro- 
matic principle which by dis- 
solving in the water can injure 
the spawn or prevent its adher- 
ence. The fascines or bundles 
of fagots, from one and one-half 
to two meters in length, are i | |
