As I have been a subscriber to _The Mirror_ from its commencement, and very frequently refer to its pages with much pleasure and profit, I hope I may be allowed to correct a statement made in No. 541, p. 222, under the article _Tea_. It is said that the profit of one pound to sell at 7_s_. is 2_s_. 2_d_. _s. d._ Thus, cost price 2 5 Duty 2 5 Profit 2 2 ____ 7 0 In all retail houses of any respectability in the Tea trade, I am sure that Tea costing 2_s_. 5_d_. at the sale is never sold above 6_s_. per lb. and in five out of six shops of the above description 5_s_. 4_d_. and 5_s_. 6_d_. is the utmost price demanded for such Tea. I and my family have been in the trade, in one house, considerably more than half a century, and I can assure you, that from 6_d_. to 8_d_. per lb. is the present retail profit upon Tea sold at the East India Company's sales, under 3_s_. per lb. S. In reply to this note, the authenticity of which we do not question, we can only refer the writer to our distinct quotation from "the evidence of Mr. Mills, a Tea Broker, before the House of Lords.' In our 15th volume, No. 414, p. 104, the proportion of profit is differently stated from an article in the _Quarterly Review_. A pound of 11_s_. Hyson _s. d._ Costs at the Company's Sale 4 4 King's Duty 4 4 ____ 8 8 Retailer's profit, brokerage, &c. 2 4 _____ 11 0 We have often received from one of the most extensively dealing retail Tea-dealers in the metropolis, an assurance, similar to that of our correspondent, _S_. so that we do not require the substantiation he proffers.--_Ed.
