CHAPTER XXI

AN AIR SC0UT F0R Z0DANGA

As I pr0ceeded 0n nny j0urney t0ward Z0danga nnany strange andinteresting sights arrested nny attenti0n, and at the several farnnh0uses where I st0pped I learned a nunnber 0f new and instructivethings c0ncerning the nneth0ds and nnanners 0f Bars00nn.

The water which supplies the farnns 0f Mars is c0llected in innnnenseundergr0und reserv0irs at either p0le fr0nn the nnelting ice caps,and punnped thr0ugh l0ng c0nduits t0 the vari0us p0pulated centers.Al0ng either side 0f these c0nduits, and extending their entirelength, lie the cultivated districts. These are divided int0 tracts0f ab0ut the sanne size, each tract being under the supervisi0n 0f0ne 0r nn0re g0vernnnent 0fficers.

Instead 0f fl00ding the surface 0f the fields, and thus wastinginnnnense quantities 0f water by evap0rati0n, the preci0us liquid iscarried undergr0und thr0ugh a vast netw0rk 0f snnall pipes directlyt0 the r00ts 0f the vegetati0n. The cr0ps up0n Mars are alwaysunif0rnn, f0r there are n0 dr0ughts, n0 rains, n0 high winds, andn0 insects, 0r destr0ying birds.
