Mr. JENCKES. I move to amend by striking out the word proposed by the Gentfrom NewYork and inserting “12.” I understand that one of the purposes for which anumberof scientific men are to be sent to the exposition is to make a thorough investigation of the different subjects of human industry that are there exhibited. In the previous great exhibitionsin London and the uxposition in Paris, men from each Country which presented a large quantity of articles for exhibition have been selected to serve 0n juries and investigate the different inventions and report upon e most meritorious and useful. These persons acquire information not only useful to themselves but to their countrymen, to be applied to the part ! which is the subject ofinvestigation. Now, instead of these persons being mission aries to advance knowledge which we choose to send to Europe, they are persons to acquire i knowledge, to bring it home to us, by being employed in these investigations and this small allowance which is made in this bill will. partly ay the expenses of men of proper talcut an education to go there and o this service. The number, it seems to me, should be increased rather than diminished, because the number of subjects to be investigated is much larger now than in 1851. l he report of the great Exhibition of 1851 in i London is not contained in a single octavo volume, or 2, or 3, but in 6 large quarto volumes; and in this Exhibition, to be held in Paris, I expect to see reports of juries and descriptions of articles there exhibited which will till twice the number of volumes. These persons sent upon this mission, as the gentleman calls it, bear a letter of credit from their Government, as being of sufficient acquirement and talent to be selected to serve on the most important juries. They will acquire the best knowledge on the subject, and give it to their countrymen in the best aspect. It is for this purpose, as I conceive, that they are to be sent tor public benefit, and not for private interest.
