on the voyage, for which purpose rain water is best. If, in any special 
case, particular instructions on this point, or upon any other connected 
with the management of the plants du^-ing the voyage, be necessary, they 
should be made known to those having charge of the plants. But, after 
all, much will depend upon the judicious care of those to whom the plants 
may be confided during the voyage. 
Plants of the succulent bind, and particularly of the cactus family, 
should not be planted in earth, but in mixture of dry sand, old lime rub¬ 
bish, and vegetable mould, in about equal parts, and should not be watered. 
It may not be necessary, in every case, to observe all the precautions 
here recommended in regard to the putting up and transmission of seeds ; 
but it is believed that there will be the risk in departing from them, in 
proportion to the distance of the country from which the seeds are to be 
brought, and to the difference of its latitude, or of the latitudes through 
which they w^ill pass on the voyage. It is not intended, however, by these 
instructions, to exclude the adoption of any other modes of, putting up 
and transmitting seeds and plants which are in use in any particular 
place, and which have been found successful, especially if more simple. 
And it is recommended that not only the aid of competent persons be ac¬ 
cepted in procuring and putting up the seeds and plants, but that they be 
invited to ofier any suggestions in regard to the treatment of the plants 
during the voyage, and their cultivation and use afterwards.

Sir : I have to call your attention to the enclosed copy of a communi¬ 
cation from the Treasury Department to the consuls of the United States 
at various posts ; and to desire that the objects of that communication may 
be promoted by you, on all occasions, as far as may be in your power. 
The Executive takes a deep interest in this matter ; and, by particular 
attention to it, you will probably confer a lasting benefit to the country. 
The letter of the Secretary of the Treasury is so full and satisfactory, 
that no farther explanations seem necessary on my part. ■ 
You will be pleased to report to. the Department Avhatyou do in execu¬ 
tion of this object, and return the papers to the Department when you are 
detached from the vessel which you now command. 
I am, respectfully, &c.
