No, Bruce. "'Tis" isn't a contraction of "THIS is." It's a contraction of "IT is."
Oxford English Dictionary on "'tis":
"Abbreviation of 'it is', formerly common in prose, now poetic or archaic . . ."
The OED's first quotation for it is dated c. 1450.
Similarly, "'twas" is a contraction of "it was" ('Twas the night before Christmas . . . ). "'Twill" and "'tain't" also exist, but the OED doesn't have entries for them.
