A question of graver and universal interest is the possibility of another attack from the Martians. I do not think that nearly enough attention is being given to this aspect of the matter. At present the planet Mars is in conjunction, but with every return to opposition I, for one, anticipate a renewal of their adventure. In any case, we should be prepared. It seems to me that it should be possible to define the position of the gun from which the shots are discharged, to keep a sustained watch upon this part of the planet, and to anticipate the arrival of the next attack.
