This is all very interesting; but that is enough as to its effect on live stock.
At the request of the Department of Agriculture I sent to Washington some specimens of a grub which, when the plant reaches its greatest exuberance and abundance, infests it, eating out its heart and so killing it.

It destroys the plant, but alas! generally too late to prevent the seed maturing and falling to earth.

The plant itself has been several times carefully examined, its juices tested and experimentally administered to various animals.

But no absolutely satisfactory explanation of its effects has been given out; and certainly no antidote or cure of its effects suggested.
Well, in a certain year the seven years' cycle came round; faithfully the loco plant cropped up all over the plains, the seed that had lain dormant for many years germinated and developed everywhere.

As winter approached (in October) my fall round-up was due.
