185.--ST. GEORGE'S BANNER.

At a celebration of the national festival of St. George's Day I was

contemplating the familiar banner of the patron saint of our country. We

all know the red cross on a white ground, shown in our illustration.

This is the banner of St. George. The banner of St. Andrew (Scotland) is

a white "St. Andrew's Cross" on a blue ground. That of St. Patrick

(Ireland) is a similar cross in red on a white ground. These three are

united in one to form our Union Jack.

Now on looking at St. George's banner it occurred to me that the

following question would make a simple but pretty little puzzle.

Supposing the flag measures four feet by three feet, how wide must the

arm of the cross be if it is required that there shall be used just the

same quantity of red and of white bunting?
