THE OLD FILTER

Renan's transmitter was singing by itself on the step when Célia came back along the corridor. The girl's voice reached the broken-off line and stopped. Thirteen minutes were left. She carried the capsule under her clothes and the visor open in her palm. She had searched the network for a magnetic assay blade, a part used to separate wear dust from ore suspended in the air. The nearest supplier showed the drawing of the part, but had removed the price. The entire production of the next five cycles was reserved for a foreign vehicle manufacturer, newly entered into the direct purchase of rare earths. Another workshop offered a reconditioned blade for the value of eight meals. Delivery would take four days. Célia closed the search. The buyer's decision had reached Buritaçu as an absence the size of two fingers. Renan raised his face. The purple band on his forearm had darkened. He counted the time by the projection on the step and held out his hand. I couldn't get the part, she said. Then give it back. Nael came away from the duct. He signalled for them to wait and went into the bar. Antônio followed him, wary since the intervention on the plate, but left the way clear. The food activity remained suspended. On the counter, the reading piece taken from the cartridge shared space with three empty glasses and the transmitter Antônio used to compose messages to his son. The young man's presence light was on. Antônio covered the transmitter with the shallow bowl. Nael crouched in front of the bar's first refrigerator, dead for years and kept under the worktop because replacement metal cost more than the space. The copper of the circuit had already been ripped out to repair the line. He pulled the casing. Behind it was an old respirator, hardened at the rim, with two layers of filter stuck together by the dust. Antônio held his arm. Since when has that been there, he asked. Nael pointed to himself, then drew in the air the curve the old excavator made before it reached the Lajes. During the visit, his speech remained forbidden, but the respirator spoke through the contact it had had with his mouth. He had used it when he was paid by the metre opened to drive the surveys. He had kept the piece when he bought the refrigerator, together with the digital receipt long since expired and a key that had lost its lock. Renan stood up. He knew that model. He brought his face close to the filter without touching it. The inner layer holds rust from the machines, he said. The outer one catches what comes in with the air. Nael broke the dried-out seam. The inner layer fell apart into three grey plates. The outer one stayed rigid, red in the folds. A small spider came out of the fitting, ran across the counter and disappeared under the reading piece. Outside, moths beat against the tracking cameras, drawn by the light that had replaced the vegetation of the slope. The leaves of the last two shrubs by the guesthouse bore the same reddish film, up to where the sap could no longer push out a shoot. Célia set the capsule beside the filter. Eight minutes were left. I'd need to open it, she said. You said you didn't need to, answered Renan. She did not apologise. She took from the collection container a rod used for water samples and offered its clean tip. Renan looked at Nael. The former miner pushed the outer layer of the respirator to the middle of the counter. The capsule opened with a click. Célia gathered less dust than an ant's head and laid half of it on the old filter. The two matters stuck with no visible difference. She tilted the layer. Both ran along the grooves and stopped in the deepest fold. The inner residue of the respirator, scraped off by Renan with his fingernail, fell in larger grains and left a dark streak. It could still be coincidence. Nael picked up the reading piece taken from the cartridge and brought its magnetised edge close. The inner grains moved forward a millimetre. The dust from the capsule and the old dust from the pit stayed where they were. Renan repeated the movement. Once, twice, three times. On the third, he separated the outer layer and put it away inside his own toolbox. Célia understood before asking. If she published only the image of the capsule, the utility company would look for the technician linked to the shift. The remains of the time when he drove the machines would lose one half. Célia captured the two dusts together, without face, without capsule, without recent tool. She sent the material to the newsroom with the provenance attributed to the air of the pit. The vehicle advertisement occupied the top band of the portal and would pay for that image to stay up for six hours. Two minutes were left when she closed the capsule and handed it over. Renan checked the seal, kept it against his chest and picked up his daughter's transmitter. Nael folded the remaining half of the respirator. Antônio moved the refrigerator casing aside, opening a space for him under the counter. Nael did not put the piece away. He walked to the veranda and fixed the old filter over the cabinet's air intake, where the new dust began to settle on the old.
