I would therefore earnestly advise the use of octagonal 446 APPENDIX. block-houses for railroad defense. So much time was con-sumed in making mortises and tenons, that I would advise forfuture block-houses a greater simplicity of joints and the lib-eral use of spikes, abolishing, as far as possible, all work re-quiring skilled labor. Spikes answered admirably on theKentucky Central block-houses, but I was induced to trytenons in Tennessee, on account of having skilled labor avail-able. I am now satisfied that the first method of construc-tion was greatly preferable. As a rule, the small railroad bridges had one block-house,and the larger ones two, on opposite sides of the track. Atthe very high and long trestle-work across the Running Watergorge at Whiteside, four small block-houses were built. Forthe protection
