Inc nature of heroism. wrong and retribution
Ploral innocence, and the myStic's "inner and

In Romeo and Juliet" Shakespeare almost
plays the part of his own commentator by tell
ing in the prologue that he is here trying to
picture not sin and its consequences, but the
entangling circumstances Of fate working above

dramatist shows the presence of a moral gov
ernment in the world, which enables each case
OF perverted right to work through by suffering
TO Its own redemption. In Henry VIII" 1t is
taught that there are two spheres in which
providence may be displayed, the life without

though. as in the more detailed studies follow
ing them, Professor Moulton forces home the
unpleasant fact that Shakespeare had no phil
osophy after all; to be sure, this lesson is not
meant but it is there. The reconciliations the
philosophical Interpreter effects between the
infinitely numerous and diverse shadings of
thought expressed in the plots Of the dramas
and the utterances of leading characters are

them shakespearian philosophy, inasmuch as
philosophy is a system of opinions about the
world and mans relation to it. Unless the

ans he can scarcely drag even a moral system

ments. TO be sure occur constantly therein, but
Professor Moulton himself is exceedingly wary
about using these, especially apart from the
plots in which they are woven. In the plots
themselves, where the interpreter seeks a philos-
ophy most hopefully what appears is a series of
ldeas that have been the heritage of mankind
Tor untold ages; Shakespeare simply presents
them in the living form of personages and

Engineers Think "Mile-a-M Minute" Boat Nav

Inc advent Of the mile minute boat may soon

Yesterday by a party of experts including naval
engineers, yachtsmen and others who got a private
view and a practical demonstration at No rs Full

Set in motion by belt gear and driven by four
piston rods which pass through stuffing boxes in
the bottom Of the boat and are connected In its
hinges the triple horizontal plates which form the
propeller worked I'D and down with the sinuous
motion Of fish. The spectators predicted that tho
propeller and It's inventor would speedily become
subjects for serious consideration IN engineering
circles; in fact, by all interested in marine or
aerial propulsion for Mr. Turner intends to apply
his system TO aerial navigation.

afterward said: 1T looks well and it works well
and IS an invention that, it seems TO me well war

as propelling motion. and It has this advantage
over the screw propeller that the surface on both
sides Of each blade plate is efficient for pro-
pulsion. while in the propeller only the front
surface is efficient
