in Local Coord's p149, show scene.add(earth) commented out

Chapter: Local Coordinates, page 149, the second example reads:

…
var earth = new THREE.Mesh(shape, cover);
//earth.postion.x = 300;
earthLocal.add(earth);


I think it should also show the line scene.add(earth) commented out, vis:

...
var earth = new THREE.Mesh(shape, cover);
//earth.postion.x = 300;
//scene.add(earth);
earthLocal.add(earth);

While the text implies this it wouldn’t hurt to spell it out (and it does note that earth.position=… is removed).
