But th'j most admirable feature of the plan 

 is this: the houses need not be all alike 



a bathroom. The two and three family 

 houses would cost proportionately less. 

 It is estimated that a four-room and bath 

 cottage built under the new method, 

 could hardly be duplicated for less than 

 $1,800 under conventional schemes of 

 construction, using the same materials. 

 The two family dwelling costing less than 

 $1,200, with four rooms and bath and a 

 porch for each user, is especially desirable. 

 The price of lumber is now so high that 

 the erection of wooden houses similar in 

 design to those here described would cost 

 from seventy-five to eighty-five per cent 

 of the sum expended for houses of brick 

 or reinforced concrete. Such costs, how- 

 ever, vary greatly according to localities 

 and the accessibility of supplies. Lead- 

 ing architects agree that after-the-war 

 developments will justify the expense. 



Real Lights for the Automobiles in 

 Motion Pictures 



MR. LANGDON McCORMICK of 

 New York thinks that the present 

 motion picture representations of night 

 scenes are not sufficiently realistic, especi- 

 ally in their lighting effects. 



It is his belief that representations of 

 light on the screen, such as lamppost, 

 automobile, and locomotive lamps, should 

 be lights in reality, instead of pictorial 

 representations. 



As most night scenes projected on the 



screen are photographed in daylight and 

 tinted blue to give the night effect, it 

 is true that there is an absence of glow. 

 But from our knowledge of motion pic- 

 ture projection we fail to see a practical 

 need in Mr. McCormick's invention. 



He proposes to arrange a number of 

 tracks behind a translucent screen, upon 

 which actual electric bulbs are to be 

 dragged along by motors. These lights 

 will be caused to move about on the screen 

 to correspond with the ever changing 

 positions of the lights in the picture. 



How this corresponding movement will 

 be accomplished we do not know, but 

 we are certain that if it is at all possible 

 it can be accomplished only more or less 

 successfully in a direct side to side or 

 up and down movement which involves 

 no perspective changes. 



As regards objects which come forward 

 or recede in the perspective of the picture 

 it is well understood that they change 

 their size during their movement. 



No provision is made for this change 

 in size of the traveling lights and if this 

 method were actually applied to a pic- 

 ture of an automobile going away from 

 us into the distance the car would be seen 

 to diminish in size while the tail-light 

 would remain unchanged, and this effect 

 would continue until the machine became 

 much smaller than its tail-light. Literally 

 speaking tlie automobile would disappear 

 in a blaze of tail-light glory.
