Although, as we have seen, the drainage capability of a bedding material varies inversely as its power of absorption, and vice versa, we can obtain both of these valuable qualities by employing two materials, one being highly absorbent, and the other having good powers of drainage. Thus, a layer of sawdust 4 or 5 in. thick, covered with a sufficiently deep layer of sound wheat straw, would make a nearly perfect bedding. Peat moss would serve the purpose of absorption even better than sawdust; but it is not so clean, and its dark colour is against it. A combined bedding would probably entail more trouble on the groom than a bedding made from only one substance.
