The tree possesses remarkable personality. Though one sees a chance specimen grow up straight as a spruce, yet its normal tendency is to “flatten out” on top, whence three, four, even a dozen independent “leaders” spring away, each with equal vigour, and finally form as many distinct vertical trunks, say six or eight separate pines all arising from a common base.
To see the pinsápo in its pristine majesty and massiveness, one must ascend beyond the range of charcoal-burners; up there flourish gigantic specimens, some of which we measured (by rough pacing) to encompass ten to fifteen yards of base. These trees grow from screes of broken rock—great blocks of white dolomite; but the deep-searching tap-roots penetrate to black alluvia beneath. Other huge pines found roothold in walls of living rock. The three sketches, made from individual trees (presumed for the purpose to be divested of foliage), illustrate the singular multiple growth described.
The foliage of the pinsápo differs from ordinary pine-needles, being rather a series of stiff outstanding spines analogous to those of the Araucaria. They display a crimson efflorescence in March, developing into clusters of red cones by April, and ripening in August to September.[58]
The pinsápo-forests are subject to terrible destruction alike by hatchet and fire, tempest and avalanche. Forest-fires sweep whole glens; while rock-slides overwhelm and uproot even the biggest trees by scores. Few scenes that we have witnessed are more eloquent of nature’s violence than these traces of an avalanche. Mammoth skeletons, weird and weather-blanched, protrude by the hundred from chaotic rock-ruin—some still upright, others overthrown or half submerged in debris, yet stretching great white arms heavenward, as though in agonised appeal. The distant roar of an avalanche is a not infrequent sound throughout the mountain-land.
The pinsápo-forests of San Cristobal present one of the most striking mountain-landscapes in Andalucia. For some three miles they cover in a semicircle the whole scooped-out amphitheatre of the mountain-side. Their dark-green masses, contrasted against the white rocks on which they grow—and in winter with yet whiter snow—cluster upwards, tier above tier, from below the 3000-feet level away to the extreme summit of the knife-edged ridge above, say 5500 feet. Would that we could depict the beauty of the scene.
Through these dark forests a track winds, and here again the evident industry of the mountaineers surprised. At intervals along this pathway lay great baulks of pine-timber (sleepers, planks, and poles), dressed and piled ready for transport. That such loads could be carried hence on donkey-back, or, were such possible, that the labour could be repaid, appeared incredible—so distant are markets and so heavy the cargo.[59]
We had hoped to find in these forests a home of the Spanish crossbill, but not a sign of it rewarded our search. To avail the ripe fruit, the crossbill would need to nest in autumn, and that (wide as is the latitude of its breeding-season) is too much even for the Pico-tuerto. An interesting species found here in March was the cole-tit (Parus pinsapinensis?), which climbed around us, swinging from twigs within a yard as we sat at lunch. Blackstarts abounded, also firecrests. The latter have a pretty habit of engaging in aërial struggle—whether for love or war—both falling locked together to earth, as blue-tits do. On one such occasion a male, ere taking wing, spread out his flaming crown fanlike, as it were a halo.
Beyond the pinsápo-forests succeeds a region of wiry esparto-grass, up which we climbed to yet more sterile zones above. Here cruel rocks are adorned with a dwarf sword-broom, steel-tipped, a thorny berberis, and vicious pin-cushion gorse that protects its newer growths (not that there is anything tender about it at any stage) by a delicate grey tracery that deceives a careless eye. For that subtle tracery is, in fact, the indurated malice of last year’s spikey armour. No handhold does nature here vouchsafe.
