A little of it mixed with a diet of grass will drive horses and cattle insane, and there is no authentic case of recovery, that I ever heard, once the infection is complete.

A lot of it will kill,--and these poor beasts had actually been staked out to graze upon it, I suppose because it looked nice and green, and the horses liked it.
The performance matched very well the enamel-trimmed oil stove and the tinned dainties and the expensive suitcases.

Casey went back to camp feeling as though he had stumbled upon a picnic of feeble-minded persons.
He wondered what in hell two men of such a type could be doing out there, a hundred miles and more from an ice-cream soda and a barber's chair.

He wondered too how "Fred" had expected to get himself across that hundred miles and more of dry desert country.

He must certainly be afoot, and the camp itself showed no sign of an emergency outfit having been assembled from its furnishings.
Casey made sure of that, inspecting first the bedding and food and then the cooking utensils.
