In the experimental period of dredge construction in this country, many failures resulted in attempting to use the hydraulic, or suction, and the dipper and clam-shell types of dredges. We have recently equipped many of these properties with successful dredges.

We are the first concern to make a specialty of export work, and we are particularly well equipped to handle this line, being familiar with the conditions existing in most of the gold-bearing placers of the world.

It also contains much valuable information and many tables of use in placer and dredge mining, and it will be sent on application.

We have done much to develop dredge architecture and to promote gold dredging in general therefore, to those interested in this subject, we suggest the reading of our booklet on “Drills and Prospecting,” illustrating the Empire Hand Prospecting Drill and its application in determining the values and characteristics of dredging or placer ground. Some of our engineers were taken from the California dredging fields, and thus we have the advantage of the many lessons learned in that country. We are the first and only concern in this country to devote its whole attention exclusively to the designing and building of gold dredges therefore, we are especially well equipped to do this work much better and more quickly than other concerns for with them, dredge building is only a side line, and their principal business, which receives their best efforts, is the manufacturing of some other lines of product.
