Finished this in late August and forgot to mention it:
Better than expected space adventure. Smith, more so than most others, can be extremely hit and miss.
Triplanetary and
The Skylark Of Space breezed along without a hitch but
First Lensman and
Galactic Patrol were chores almost beyond belief.
Spacehounds is somewhere inbetween being both creative and bizarre and has a rocket science which while no doubt completely unrealistic retains an internal logic that never seems to contradict itself. I may not understand it but it feels right when bashed back and forth between the several scientists trying to figure things out. The problem, and it's a pretty big one, is the dialog. Hard to take at times. This is one case where a new edition with normalized dialog would be justifiably celebrated.
