I see I haven't explained very well. I'll try to rectify that.

No, the camels sucked in many extra gallons of water, sufficient to their needs for the forced-march ahead of them.

In preparation for the eleven-day trek across the burning sands the camels were led to a watering hole where they spread both front and back legs to access the water. As they began drinking, one of the soldiers carrying two bricks approached each camel from behind and in a motion much like clapping one's hands together slammed the Adobe bricks together on the protruding bits of the camels' reproductive systems. This caused them to drink very deeply. When it was remarked that it must hurt, Manuel said, "Not if you keep your thumbs out of the way."

I have been thinking that the Adobe Method should work for bass, alto, tenor and possibly soprano singers, also.
