A search on Google Books for "spare made" gave me this: http://tiny.cc/2ip6tz http://tiny.cc/2ip6tz Which gives us "spare made", "well made", and "well set" as descriptions. A similar "ethnography" (http://tiny.cc/3ip6tz http://tiny.cc/3ip6tz) gives me this: "Although from their wiry and spare conformation of body, the Villees look tall, they are not so in reality." Which I would think implies thin.
