(2) Another type of collector is the bouquet* employed when the bottom is suitably 
firm, but tvhere from depth of water the gabaret is inconvenient. This collector is 
simply a bunch of a dozen tiles 
strung together in different ways 
by galvanized wire. Its wire loop 
is readily seized by a boathook, and 
its compactness makes it conven- 
ient in handling. 
The musliroom is the form almost 
exclusively used where the banks 
are soft, or in deeper water where 
there is a heavy bottom sediment 
to be avoided. Without this col- 
lector many localities would be ren- 
dered absolutely worthless. It is 
simply a bouquet raised a foot or 
two above the bottom, hung by its 
wire ring to the top of a firmly 
driven stake. All the attendant 
care is readily given from flat-bottomed skiffs as the tide is falling. 
Another modification of the bouquet is the camion (Plate lxx, Fig. 2), a collector 
used in place of the gabaret in localities where the current is not too strong. It is a 
gabaret lacking the wooden frame, formed by banking together bouquets , one above 
the other. It is therefore readily taken apart and handled. To aid its stability it is 
sometimes weighted by stones. 
(3) In place of the gabaret, 
equally exposed by the reced- 
ing tide, there is often em- 
ployed a planche collecteur , or 
a bank of a dozen horizontal 
wooden trays (Plate lxxi, Fig. 
1). This collector is kept in 
position by rough uprights 
driven into the ground, which 
serve from year to year. The 
wooden trays are easily re- 
moved and transported for 
detroquage or reliming. 
We must now examine (1) 
the way in which the tiles are 
coated with cement, (2) how 
the collectors are put in place, and (3) how the young oysters are afterward separated. 
* The bouquet is shown in the upper figure; the second figure represents th e planche collecteur.
