Sunday afternoons, and may be seen sitting under the trees, sometimes in a state of great excitement, as they busily sell or exchange any of their surplus stock for some of which they may have been in search. The gathering of a complete set of postage-stamps, and a proper arrangement of them, is at least a harmless and innocent amusement. On this point, however, we prefer, in conclusion, to let Dr. Gray, of the British Museum, speak,[179] and our readers to judge for themselves. "The use and charm of collecting any kind of object is to educate the mind and the eye to careful observation, accurate comparison, and just reasoning on the differences and likenesses which they present, and to interest the collector in the design or art shown in their creation or manufacture, and the history of the country which produces or uses the objects collected. The postage-stamps afford good objects for all these branches of study, as they are sufficiently different to present broad outlines for their classification; and yet some of the variations are so slight, that they require minute examination and comparison to prevent them from being overlooked. The fact of obtaining stamps from so many countries, suggests to ask what were the circumstances that induced the adoption, the history of the countries which issue them, and the understanding why some countries (like France) have considered it necessary, in so few years, to make so many changes in the form or design of the stamp used; while other countries, like Holland, have never made the slightest change. "The changes referred to all mark some historical event of importance--such as the accession of a new king, a change in the form of government, or the absorption of some smaller state into some larger one; a change in the currency, or some other revolution. Hence, a collection of postage-stamps may be considered, like a collection of coins, an epitome of the history of Europe and America for the last quarter of a century; and at the same time, as they exhibit much variation in design and in execution as a collection of works of art on a small scale, showing the style of art of the countries that issue them, while the size of the collection, and the number in which they are arranged and kept, will show the industry, taste, and neatness of the collector."

[175] The Mulready envelopes are regarded as great curiosities by stamp-collectors, and as their value rose to about fifteen shillings, a spurious imitation found its way into the market, usually to be had at half a crown. In 1862, stamp-dealers were shocked by the Vandalism of the Government, who caused, it is said, many thousands of these envelopes to be destroyed at Somerset House.
