28. The Court, if satisfied of the fact of such desertion, and that the same was without reasonable excuse, and that the wife is maintaining herself by her own industry or property, may make and give to the wife an order protecting her earnings and other property from her husband and all creditors and persons claiming under him. Every such order shall state the time at which the desertion commenced, and shall, as regards all persons dealing with the wife in reliance thereon, be conclusive as to such time.
