of quaraiitiiie No. o7. Althoiigcli the relatively luL-jie proportion of the importa- 
tions from Canada and Mexico consist of baggage and cargo shipments, for 
which the mail-entry procedure is unsuitable (thus tending to keep the percent- 
age of total mail shipments at a relatively low figure), r)8 percent of all imiK)r- 
tations under quarantine No. 37 came by mail. Only 12 percent of the bulb 
shipments, under regulation 3 of quarantine No. 37, arrived by mail, but 90 
l)ercent of all other importations under that regulation were imported by that 
means. Of the importations entered under regulations 14 and 1.") of the same 
(piarantine, 59 percent and 12 peix?ent, respectively, entered through postal 
channels. 
MEXICAN-BORDER SERVICE 
With the improvement in economic conditions and the completion of im- 
portant highways in Mexico, there has been a decided increase in the amount 
of travel between Mexico and the United States. This increase in traffic is 
reflected in the increase in the vehicular and baggage inspection at certain 
ports during the year and also in the number of interceptions of prohibited 
and restricted plant material. The number of freight cars entering from 
Mexico in< r(>ased from 27.259 in the fiscal year 1936 to 32,050 in 1937; likewise, 
there was an iiu rease in the number of cars contaminated with cottonseed from 
1.179 the previous year to 2,034 this fiscal year. The number of railway cars 
fumigated increased from 8.181 in the fiscal year 1936 to 8,226 in 1937. All 
lailway cars found to be contaminated with cottonseed were required to be 
cleaned before entry was permitted. The usual fee of $4 was charged for each 
car fumigated and all fees collected were covered into the Treasury as miscella- 
neous receipts. 
A summary of the railway-car inspection and fumigation is shown in table 
26. In addition to the freight cars listed in this table. 4.123 Pullman and 
passenger coaches entered and were inspected at the following ports : Eagle 
Pass. 8; El Paso. 1.160: Laredo, 2,487; Nogales, 465; and Presidio, 3.

2 The apparent discrepancy in fees collected and the num.ber of cars fumigated may be explained by the 
fact that it is custom.ary for the railroads to purchase fumigation coupons in advance. 
Plant-quarantine inspectors at Mexican-border ports take an active part, 
in cooperation with the customs service, in the inspection of vehicles, baggage, 
personal etfects, and express packages from Mexico. A total of 315,736 pieces 
of baggage and 3.795,609 vehicles were inspected. This inspection resultwl in 
the interception of large quantities of prohibited and restrict(»d plant inateri.il. 
a record of which may be found in table 29.
