We also visited the anthropological department, and I was much interested in the relics of ancient Mexico, in the rude stone implements that are so often the only record of an age--the simple monuments of nature's unlettered children (so I thought as I fingered them) that seem bound to last while the memorials of kings and sages crumble in dust away--and in the Egyptian mummies, which I shrank from touching.
Great care is necessary to prevent the heaps from becoming too hot, in which case the clay becomes baked into hard lumps of brick-like material which cannot be broken up. With careful management, however, the clay dries and bakes, becoming slowly converted into lumps which readily crumble into a fine powder, in which state it is spread over and worked into the land at the rate of 40 loads per acre.
Towards the northern end of Malabar hill lie the Parsee Towers of Silence, where the Parsecs expose their dead till the flesh is devoured by vultures, and then cast the bones into a well where they crumble into dust.
The clay should be only slightly burnt, so as to make it crumble down readily; in fact, the fire should not be allowed to break through, but should be constantly repressed by the addition of material.

The barrier that separated the Arabs from the conquered nations begins to crumble away.
The empire certainly was wealthy and of enormous extent, for there were successively added to it the rich kingdoms of Bijapur and Golconda, but it was internally decaying and ready to crumble away before the first vigorous assault.
When dry they crumble into small pieces which can be readily mixed with the soil by ploughing.
The book's ancient pages were so brittle, he feared they would crumble before he finished.
