Prior to 1877 the Central Authority held that children boarded out within the union, being merely cases of outdoor relief, did not require these precautions. From 1877 onward similar precautions were required in their cases. Such children became thus differentiated from other children on outdoor relief, on whose behalf no such requirements are insisted on. For the boarded-out children a payment was approved of 4s. a week each (afterwards raised to 5s.), a sum to be contrasted with the 1s. or 1s. 6d. for each child which is the usual sum allowed for each child on ordinary outdoor relief.[638] [638] The rate of 1s. and one loaf for the support per week of each child on outdoor relief was deliberately sanctioned, in 1869, by a Conference of Metropolitan Guardians, presided over by Mr. Corbett (Mr. Corbett's Report of 10th August 1871, as reprinted for official circulation in 1873 by the Central Authority). The dividing line between children merely on this outdoor relief, and those "boarded out" at 4s. or 5s. per week, it must be remembered, is not kinship, but whether or not the person with whom the child lives is legally liable for its maintenance. Thus, the policy of the Central Authority has been that children living with a stepfather and stepmother, with a widower stepfather, with a widowed stepmother, or even with a brother, a sister, an uncle, or an aunt (none of whom is legally liable for their maintenance) require all this elaborate supervision and protection; whereas if the children live with their own mother and father, with their widowed mother, with their widower father, with any or all of their grandparents, or exposed to the tender mercies of a father and stepmother, no such supervision and protection is insisted on. But although this is the rule, we are informed that the Central Authority, in practice, now makes no difficulty, if applied to, in sanctioning the transfer of children living with grandparents, uncles and aunts, or brothers and sisters, from the category of ordinary outdoor relief to the more regulated and more richly endowed category of boarding-out. It still objects in the case of parents (_Selections from the Correspondence of the Local Government Board_, vol. iii. 1888, p. 187; _Decisions of the Local Government Board_, 1903-4, by W. A. Casson, 1905, p. 78).
