and socket joints, or a piece of tubeing at one end, and a ball nicely 

 fitted to its interior at the other. The ball has a pin run throujih 

 its center, and the tube has a slot an inch long cut in its and to 

 receive it. This allows of a slight deviation from line, and gives 

 us what is quite as essential — any amount of inchase, with certainty 

 of action. If much deviation from line is required, we use the 

 imiversal joint. Every ten or fifteen feet, a short piece is set in a 

 frame and made permanent. For the north tower, the power is 

 taken oil' by a pinion from the main wheel. The first rods ruu 

 down forty-five feet, thence across to the other tower sixty feet, 

 and then up to the dials seventy feet, making the distance, from 

 movement to dials, one hundred and seventy-five feet. The center 

 between the towers will rest on the organ, where a six-feet dial is 

 also to be placed, making seven dials in all. If these connections 

 are properly put up, they will carry very easy, and last as long as 

 the rest of the clock, besides allowing a movement to be put below 

 all vibrations of the tower. 



A duplicate of this clock is now being put up at Rock Island, in 

 the new -arsenal our Uncle Samuel is building there. It will carry 

 four twelve-feet dials. The dials are of stone, built in the tower, 

 which is large — about thirty feet square at the dials, I think. I 

 hope they may prove a credit to our city, as well as to their 

 designer, my very worthy friend, Mr. A. S. Hotchkiss. The clock 

 that was destroyed by the fire at St. George's, had run eighteen 

 months without having the hands changed. I set the new one, 

 about November 1st, three seconds fast. It has not been altered 

 since, and to-day it shows very good running, I think, it being 

 hardly regulated. 



The clocks in the Brick Church, and St. Theresa, are small but 

 well made, and if well taken care of would keep good time. They 

 are cared for by the sextons, and get no caie at all. 



I have a few words to say about the clock exhibited at the late 

 fair, if only to correct the impression among many that Remontoir 

 is the name of an escapement. A Remontoir can have a pin, Gra- 

 ham, Detached, Chronometer, or any other kind of an escapement. 

 This was a complicated aflair, but Crane never madfe an escapement 

 but what was. The idea was taken from Harrison, and the same 

 line of thought runs through all of Crane's work, and he seems 

 determined to fight it out on that line if it took a lifetime, but 

 eternity came before he had succeeded in making a good escape- 

 ment. His favorite hobby was transmitting power by a ratchet
