Since we wrote last, we have had a more accurate and general investigation in reference to the condition of this crop, in the gardens within a few miles round the city; and the intelligent and every way competent gentleman to whom the task has been entrusted, gives it as his opinion that there is no trace whatever of disease– and that in no one instance has he been able to discover a symptom of the last years’ blight.

We have equally good accounts from Carrigaline, a great potato-growing country; also, from Whitechurch; from Fermoy, and a number of other localities.

Mr. WILLIAM CAHILL of Ballinoe called at this office, on Monday, and showed us a stalk to which was appended a cluster of nearly full-grown ash-leave kidneys; and neither upon bulb or stalk was there the least trace of the disease.

Mr. CAHILL also stated an important fact– that he had six or seven different descriptions of potato set; and in no one variety could he discover a symptom of the blight. He added that many were grown from seed that had been tainted.

It is stated in Cork that all the rumours may be easily traced to corn speculators, who, to serve their own selfish ends, would circulate that or any other disheartening rumour.
