: A simple graph G = ( V, E ) admits an H -covering if every edge in E belongs to a subgraph of G isomorphic to H . We say that G is Smarandachely pair { s, l } H -magic if there is a total labeling f : V ∪ E → { 1 , 2 , 3 , · · · , | V | + | E |} such that there are subgraphs H 1 = ( V 1 , E 1 ) and H 2 = ( V 2 , E 2 ) of G isomorphic to H , the sum and P v ∈ V 2 f ( v P e ∈ E 2 f ( e ) = l . Particularly, if s = l , such a Smarandachely pair { s, l } H -magic is called H -magic and if f ( V ) = { 1 , 2 , · · · , | V |} , G is said to be a H -supermagic. In this paper we show that edge amalgamation of a finite collection of graphs isomorphic to any 2-connected simple graph H is H -supermagic.
