Every farm road end has a gate across it with disinfectant, straw and sawdust.
There are now seven types of hut being made, some of plywood, others of asbestos cement, others of concrete, of sawdust cement, and so on.
All of us know that even pattern-makers who have inhaled sawdust for some years suffer from pneumoconiosis.
Sawdust filled the tube above and below the larvae and the tubes were then placed upright in a sawdust-filled bucket (30 cm in diameter, 25 cm in depth).
Wet sawdust slightly heavier than water was used to visualize the flows below breakers.
Mature larvae hopped from the medium into sawdust where they pupariated.
Each morning most of the manure was removed; the stables were only mucked out every third day and the sawdust replaced.
Which tube received the home, neighbouring or distant wadi intruder's sawdust was randomized across residents.
