...paintings on exhibition, only four were attributed directly to Leonardo. The rest, wavering between chill sentimentality and brown gloom, either anticipated or copied the Master's favorite tricks: chiaroscuro (strong contrasts of mingled light and shadow), sfumato (blurring of outlines to suggest space), geometrically involved compositions and ambiguous half-smiles...
...hairs. Using the Renaissance technique of egg tempera painting on wood panels, Hurd confines himself to precise portraits of people and places, dramatized by isolated figures, long shadows and cold, gleaming colors. The paintings that tell of the barren hills and washes, the deserts and clear bright light of New Mexico are as knowing and sincere as an honest man's praise of his own family...

From the first, his primary concern has been to preach and minister to men. But in his spare time he has devoted his energies tirelessly to visiting the studios of artists everywhere and telling them that the Church is where their work belongs. In addition he founded, twelve years ago, the little magazine L'Art Sacr...
...Schmidt spent years studying the failings of refracting (lens) telescopes and reflecting (mirror) telescopes. Finally he devised a sort of compromise. His telescope has a concave spherical mirror, which is much easier to make than the parabolic mirror of a reflecting telescope. In front of it, to bring the light to a focus without "spherical aberration," is a correcting plate so slightly curved that it looks like plain sheet glass. The Schmidt telescope's advantage: it can take pictures of large patches of sky and have them turn out as sharp on the edges as in the center...
...Schmidt reaches about 300 million light-years into space-less than one-third as far as the 200-in. - but it is more efficient than any earlier instrument designed for survey of the sky. As the Schmidt's pictures become available, astronomers all over the world will study them eagerly...
