Mammoth Cave in Idaho. About twenty-eight miles from Boise City, Idaho, there has been discovered dis-covered what is d to be the largest cave in that part of the Northwest, North-west, and the largest in Idaho. It measures nearly half a mile in length, that is from its mouth to the lake. Of course it may be that long again, but owing to the lake it is impossible to get the exact length without a boat. The government is unaware of its existence, ex-istence, as it is located on unsurveyed land and in an exceedingly desolate region. Should the government become be-come aware of its whereabouts it would immediately claim it.
