shall hardly be able, working with all despatch, to install the Diplodocus as it ought to be installed until the end of May. It requires about four weeks to effect the installation of one of these skeletons in the manner in which it should be done. I will therefore come to PAris about the beginning of June. This will enable me probably to complete the work of installation in such a manner that everything will be in shape with you at the end of the month of June. I regret that it is impossible for me to be in two places at the same time. There are intricacies in the work and there is a special knowlwedge that we possess which we cannot very well impart to others, and I doubt whether it would be possible to have your workman - although they are undoubtedly very skilful - to effect the installtion as it ought to be effected without my presence. It may be however for the best that things should be as they are, for I know that Mr. Carnegie at present does not comtemplate going abroad until very late this year, and my delay in coming to Paris may eventuate in our having the pleasure of having him personally with us in June, which certainly would not be the case, as I now udnerstand matters, if the inauguration were to take place in May. I do not thing he will arrive on your side of the Atlantic himself until toward the end of May and possible not until June. His movements are very undecided as yet. I will not take time just now to write more, but will push the work along as rapidly as I can. Thanking you very much for all your kindness and your attention to my requests for information, assuring you of my most perfect consideration, I am Yours very truly, Director Carnegie Museum
