rope. The greater part of the apparatus 

 used was either new or improved forms of 

 that ordinarily used, and much of it was 

 due to the ingenuity of Commander Sigs- 

 bce. The present work does not go into 

 the results obtained by the various expedi- 

 tions, but is devoted to a description of the 

 apparatus employed and statement of its 

 actual value in use. Detailed drawings sup- 

 plement the descriptions, and a large num- 

 ber of heliotype plates clearly show the 

 arrangement and method of using on board 

 ship.

POPULAR MISCELLANY. 



Improved Safety Construction of Ele- 

 vators. With an appliance in such general 

 use as the elevator, means of securing safety 

 in case of the parting of the cable, or failure 

 of other parts of the moving apparatus, are 

 of prime importance. A great variety of 

 devices, many of them quite ingenious, have 

 been designed to accomplish this object, 

 but few of them are entirely satisfactory. 

 They have done much to decrease accidents, 

 but these still happen frequently enough 

 with them to show the necessity of a more 

 perfect apparatus. These mechanical stops 

 consist of combinations of levers, pawls, and 

 clutches so arranged that the weight of the 

 carriage will throw them into action. Both 

 classes, those which bring the carriage to a 

 sudden stop, and those which act as a break, 

 need to begin to act the moment the fall 

 commences, or the motion becomes so great 

 as to be beyond control. From various causes 

 impossible to provide against, these devices
