Mr. Hyatt states on his own knowledge. He states himself, as a fact, that he has never received even half of this sum which is attrib uted to him. And now, sir, the question occurs, has he received a sufficient reward or compensation for his patent? That leads to the question of the value of the invention. On that I have already adduced the very strong testimony of the ComrPatents, who gives itas his positive opinion that the invention is of very great and peculiar value; but it needs no oliicial testimony for Senators to see that it is of great and peculiar value. The character of the invention itSelf is so obvious, it goes so to the understanding the moment you begin to look at it, that no one can hesitate to say that it is of great and pecu liar valuc. It may be regarded, as I understand it, in 2 different aspects: 1st, as a light to cellars and bringing into use cellars and underground apartments which before this invention were absolutely useless, but which are now brought practically into the light of day, so that immense spaces in all our large cities, and especially in NewYork, are now used for merchandise which formerly were absolutely idle, yielding no profit of any kind. Thus an immense amount of taxable preperty is brought forward to contribute to the expenses of the Government. From the memorandum I have in my hand I read this statement on that point: "At the presenthour. too, there is lying below the sidewalks of the greateity of NewYork taxable real estateto the value of $5,000,00uop, on which the city governmenteollectstaxes to the extent of $40,000a you, whilo the ownersderivefrom it an annual revo nuo of 9100.00moore." Thus in the city of NewYork alone that vast amount of propertyis broughtto the light of day, if I may so express my If, and made to contribute through taxation to the resources of this Government. Then this light is applicable in another way. It is used in roofs as a covering there, and is fire roof, and through its fire proof character builings and merchandise of vast amount have been protected from conflagration. For in stance here is a statement on that head: "At this hour morethan 100 million dollars'worth of merchandise is nightl protectedin the city of NewYork against fire antf iiurglnry by my vault lights. manufactured into illuminatin: roofs, which cover the rear extensions of the principal storiesof warehousesin that city.” These are the 2 different aspects in which this invention may be seen. In each aspect its value is apparent. Thus in each does it contribute to the resources of the city or place where it is, enlarging the taxable property and also contributing to the wealth of the owners. I think, therefore, I do not go too far when I say that such an invention is valuable in its character. Now, the question is whether the inventor has received enough from the patent. It appears, and no one I believe will question itthe chairman of the committee certainly will sustain me in what I say that during the 1st 7 years he actually received nothing, so thatthose 7 years may as it were he counted out. Then came the 2nd 7 years when he began to get his invention into use, but during that time he received little more than what belon ed to him as a manufacturer; he receive very little on account of what is some times called the “royalties” from the invention. Then the patent was renewed for 7 years, and during that time he and all concerned received some $120,000, out of which, not 1/2 has come to him. Under those circumstances he comes before Congress asking an extension of his patent for another 7 years. Now, sir, it does seem to me that in making this request he is perfectly reasonable. '1‘ e 1st 7 years of his patent were nothing; the 2nd 7 years were very little; it is only during the 3rd 7 years that he has begun to receive any thing; and what he has received, 1 submit, is a very small consideration for the invention that he has bestowed on the community. I think, sir, if we give him another 7 years we shall do nothing more than follow out the principle of the Constitution which authorizes Congress to legislate for the benefit ofinventors. ‘I do not know that I can add anything more to this very simple statement. I put the case on its essential simplicity; and I put it also on the statements which I have rea from the in ventor himself, in which I place implicit confidence.
