prohibited by law, unless the authorities of the State into 
which such swine are being imported provide suitable and safe 
conveniences for the absolute isolation and quarantining of such 
imported hogs at selected points of entry, so that each lot can be 
safely and securely confined in a previously cleansed and disin¬ 
fected hog-pen. 
In all such cases the State would be liable should the imported 
hogs become infected while in the quarantine pens, if the latter 
had not been previously cleansed and disinfected, or, on account 
of neglect of duty on the part of any servant of the State 
attached to the quarantine. 
In order that the pens of such a State quarantine station shall 
constitute a safe and suitable place for such imported hogs, it is 
absolutely necessary that they be individual pens of variable size, 
that the walls be made of the hardest bricks and the gates of 
iron, and if any portion of the pens be roofed that the same be 
of iron also, and the bottoms made of cement, not pitch, asphalt. 
The feeding troughs should be made of stone or iron and of such 
a size as to be convenient to handle and cleanse. The pens should 
be at least ten feet apart; the passage-way between them should 
be made of cement asphalt and so graded that the drippings or 
washing from each pen could not run over to the opposite pens. 
The entire quarantine grounds should be paved with cement 
asphalt and sewered. The drainage from each individual pen 
should enter the sewer from a trap within the walls of the pen, so 
that in washing them no material could possibly get outside the 
pen. 
The quarantined hogs should be inspected daily by a compe¬ 
tent Veterinary Inspector, for a period of twenty days subse¬ 
quent to their arrival upon the State territory into which they 
were imported. 
If no evidence of swine-plague or other suspicious disease 
occurred during that period, the hogs should be declared free and 
released to the owner. 
The State authorities should take such measures as would in¬ 
sure their further transport into the State in cars or conveyances 
that had been previously cleansed and disinfected under the eye
