vision in manufacturing, many desisted. Dr. A. H. Ide, of 
Utica, N. Y., was determined, however, to have a duplicate of

have two sets made and send one to him, to which he kindly

cess of manufacturing the first set, he saw many opportunities 
for improvements in the way of a self-locking device and other 
modern methods, and when he finally had it ready to ship the 
principle was about the only resemblance between it and the 
original one. The Review commented upon the harness in its 
October issue, and it has received several letters asking a de¬

answer to their inquiries mainly, we have asked Dr. Ide to 
furnish us with a drawing of the harness in position, together 
with a description in detail of the apparatus, and herewith we

is freed from all fetters. 2 shows strap to be applied after horse
